CERT. OF AUTH. # 31333 Alpha Roofing & Sheet Metal, LLC April 22, 2019 1477 West Gore Street RE-19-086-loc Orlando, Florida 32805 Re: In -Progress & Final Roof Inspections 300 Northstar Court Sanford, FL 32771 Permit# BC19-000159 Letter of Compliance This correspondence is in reference to the recently installed TPO roof system located at 300 Northstar Court in Sanford, Florida. The above referenced installation was done on an existing standing seam metal roof deck using a GAF 60-mil TPO roof system. Evaluation of the roof criteria and installation was done by an examination of photographs obtained from Alpha Roofing & Sheet Metal, LLC. The existing roof deck consisted of a standing seam metal roof deck, supported by 16 gauge steel purlins spaced at 60" o.c. The recover roof fastening system was designated to be a GAF 60-mil TPO RhinoBonded onto the mechanically fastened insulation plates, as per Florida Product Approval. #5293 Page 98, System No. R-182. This system has a Design Pressure of -45 psf, which exceeds the Field Pressure of -28.3 psf. The maximum roof uplift pressure was P3 Corner at —71.5 psf. Based upon this criteria; the Florida Approval calls for preliminarily fastening the flute fill & insulation using 6 fasteners per board and subsequently fastening 12.0" o.c. along the 16 gauge purlins in the Field Zone. Enhancements are required within the Perimeter & Corner Zones. Using a GAF fastening pattern recommendation, the spacing along the 16 gauge purlins was decreased to 6.0" o.c. in both the Perimeter & Corner Zones. The insulation was preliminarily attached using Drill-Tec # 12 screws w/plates and secured into the purlins with Drill-Tec Purlin Fasteners and RhinoBond XHD Plates. The 60-mil GAF TPO was subsequently RhinoBonded onto the insulation plates with a RhinoBond portable bonding tool. Based upon examination of the photographs obtained from Alpha Roofing and the wind uplift pressure calculations; it is evident that the roofing system is installed as per the above -referenced Florida Product Approval, and therefore is acceptable. Note that the perimeter and corner enhancements recommended by GAF actually exceed the calculated requirements, resulting in additional strength to the roof system. All wind uplift pressures and fastening patterns for the perimeter and corner enhancements were calculated and verified by RE-CSI. RE-CSI will continue to provide consulting services upon request. If further assistance is required, or questions arise concerning this letter, please do not hesitate to contact this office. Respectfully Submitted, Digitally signed by Donald J Donald J. Flood, P.E.

If possible, examine the underside of existing metal panel roof system to confirm the existence of supplemental purlins at corner, perimeter and/or ridge areas. If supplemental purlins exist, the roof membrane should be mechanically attached to these purlins per the fastening patterns applicable for the roof zone. Wind Load Testing: The following standards are commonly used to determine the wind resistance (i.e., uplift) for roofing systems. ASTM E1S92, "Standard Test Method for Structural Performance of Sheet Metal Roof and Siding Systems by Uniform Static Air Pressure Difference." ASTM E1592 covers the evaluation of the structural performance of sheet metal panels and anchor -to -panel attachments. FM 4474, American National Standard for Evaluating the Simulated Wind Uplift Resistance of Roof Assemblies Using Static Positive and/or Negative Differential Pressures." FM 4474 evaluates simulated wind uplift resistance of complete roof assemblies by using static pressure differentials. UL 580, "Standard for Tests for Uplift Resistance of Roof Assemblies." UL 580 evaluates the roofing system and the roof deck attachment to the supports. UL 1897, "Standard for Uplift Tests for Roof Covering Systems." UL 1897 evaluates a roof covering system's method of attachment, including all components, by using differential air pressures. Some components of a roof deck system are not evaluated by these test methods. For example, secondary supports such as beams, purlins and joists, and the connections from secondary supports to the main structural system, are not evaluated. It is imperative that the attachment capacity of the purlins to the secondary structure is greater than rn the attachment capacity of the metal panels to the purlins. m vsN Structural Performance a There are structural design considerations when installing a TPO/PVC mechanically attached retrofit roofing system over existing metal roof panels on a metal building, such as: 0 Dead load: Additional dead load may come from two sources: o Added weight of the new roof (albeit minimal), and o Added loads during winter from a lack of melted snow due to reduced heat loss from 2 the insulation upgrade in the retrofit roof system. a L Additionally, if the building is located in a jurisdiction that adopted the 2012, 2015 or 2018 v International Existing Building Code (IEBC) and any one of the two conditions listed below occur due to reroofing, then the affected structural elements carrying the increased loads must be Copyright© 2019 GAF • 1 Campus Drive Parsippany, NJ 07054 • www.gaf.com 4 EverGuardO Metal Retrofit Published 312019 EVERGUARD® TPO FLASHING STRIP MIN. 8" WIDTH EVERGUARDm TPO MEMBRANE — ENERGYGUARD® INSULATION — ENERGYGUARD INSULATION FLUTE FILLER DRILL -TECH" PUP- iu cncrcuFw; AND PLATES EVERGUARDP TF ENE ENE FLU' DRIL AND._..__ TPO MECHANICALLY ATTACHED SYSTEMS SPECIFICATION PLATE - EVERY PURLIN MEMBRANE TYPE CONSTRUCTION TYPE INSULATION T = TPO R = RECOVER I = INSULATED r EXISTING LIETAL PANEL ROOF STRUCTURAL PURLING T MA R MEMBRANE ATTACHMENT MA = MECHANICALLY ATTACHED 1 6a t MEMBRANE (THICKNESS AND TYPE) 45 = 45 MIL SMOOTH 60 = 60 MIL SMOOTH 80 = 80 MIL SMOOTH 50EX = 50 MIL EXTREME 60EX = 60 ML EXTREME 70EX = 70 MIL EXTREME 80EX = 80 MIL EXTREME MEMBRANE TYPE I MEMBRANE ATTACHMENT I CONSTRUCTION TYPE I INSULATION GUARANTEE, LENGTH UP TO 20 YEARS The attachment capacity of the purlins to the secondary structure must be greater than the attachment capacity of the metal panels to the purlins. n0v m s NO O D T nm 3 C 0 m vm m. v m z O4 A d 0 3 EVERGUARDm PVC FLASHING S RAIN. a- WIDTH EVERGUARD® PVC MEMBRANE ENERGYGUARD* INSULATION — ENERGYGUARD® INSULATION — FLUTE FILLER DRILL-TEC' PURLIN FASTENERS AND PLATES EVERGUARIP PVC ENERGYGUA ENERGYGUA IMF FLUTE FILLET DRILL-TECTM AND PLATES PVC MECHANICALLY ATTACHED SYSTEMS SPECIFICATION PLATE - EVERY PURLIN EXISTING METAL PANEL ROOF STRUCTURAL PURLIN' MEMBRANE TYPE ' 7,-- P = PVC I = INSULATED P MA R MEMBRANE ATTACHMENT MA = MECHANICALLY ATTACHED REEM-11 MEMBRANE (THICKNESS AND TYPE) 50 = 50 MIL SMOOTH 60 = 60 MIL SMOOTH 80 = 80 MIL SMOOTH 50XK = 50 MIL SMOOTH 60XK = 60 MIL SMOOTH 80XK = 60 MIL SMOOTH 50KEE = 50 MIL SMOOTH 60KEE = 60 MIL SMOOTH 80KEE = 80 MIL SMOOTH MEMBRANE TYPE I MEMBRANE ATTACHMENT I CONSTRUCTION TYPE I INSULATION I 111 GUARANTEE LENGTH UP TO 20 YEARS 1 The attachment capacity of the purlins to the secondary structure must be greater than the attachment capacity of the metal panels to the purlins.

Design Considerations & Application Guidelines Mechanically Attached And Drill-TecTm RhinoBond° Roofing Systems The following are additional guidelines for roofing professionals on projects involving metal roof retrofit assemblies. Substrate Surface Preparation & Site Conditions 1. Substrates must be inspected and accepted by the contractor as suitable to receive and hold roof membrane materials. Substrate preparation is the sole responsibility of the building owner or roofing contractor. All defects in the substrate must be corrected before roofing work commences. 2. Confirm the adequacy of the new roofing system to provide positive slope to drains. Eliminate ponding areas by the addition of drainage locations or by providing additional pitch to the roof surface. 3. Obtain verification that the building structure can accommodate the added weight of the new roofing system. 4. When staging materials on the roof during application, ensure the existing metal roof and structure are not temporarily overloaded by the weight of construction materials. Rolls of membrane, especially the 12 ft. (3.05 m) wide rolls, are exceptionally heavy. 5. The existing metal panel roof system must be free of visible moisture, such as ponding water, ice, or snow. 6. Prepare substrate surfaces thoroughly prior to application of new roofing materials. This is particularly important for re-cover and reroofing applications. Providing a smooth, even, sound, clean, and dry substrate minimizes the likelihood that underlying deficiencies will cause premature deterioration or even failure of the new roofing system. 7. Preparation includes, but is not limited to, removal of existing flashings, replacement of wet/damaged existing roofing materials, removal of loose aggregate, removal of abandoned equipment, supports and penetrations, securement and replacement of damaged and deteriorated metal decking, etc. 8. All defects in the existing metal panel roof system must be corrected before new roofing work commences. Verify that the deck surface is dry, sound, clean, and smooth, and free of depressions, waves, or projections. 9. Confirm quality and condition of existing metal panel roof system by visual inspection and by fastener pull-out testing. GAF recommends that these test results to be kept on file as part as part of the acceptability of the substrate surface for a Diamond Pledger' Guarantee. 10. Remove all existing flashings and clean substrate surfaces of all adhesive contaminants. If the wall/ curb flashings are in good condition and tightly adhered to the substrate, new TPO or PVC Copyright© 2019 GAF - 1 Campus Drive Parsippany, NJ 07054 - www gaf.com flashing materials may be installed over existing flashings to a height of 24" (610 mm) without adhesives. 11. Remove abandoned equipment and equipment supports. Replace Raise equipment supports to allow the installation of full -height flashings. 12. Protect building surfaces against damage and contamination from roofing work. 13. Where work must continue over completed roof areas, protect the finished roofing system from damage. Fasteners & Plates 1. Drill-TecT"° Purlin Fasteners. Refer to the appropriate Attachment Tables in this Guide for fastener spacing and pull-out requirements. 2. Drill-TeCT" RhinoBond° Fastening Plates. 3. Drill-TecT" 2 3/8" (60.3 mm) Barbed XHD Plate and 2" (51 mm) Double -Barbed XHD Plates. 4. Drill-TecT"" "flat" plates (without the countersunk screw holes protruding from the bottom of the plates) are required when plates are installed over hard surfaces such as DensDecke, SECUROCK° or other hard cover boards to allow the plates to rest flush on the surface. 5. Drill-TecT"" XHD Fasteners and plates can be used for supplemental insulation attachment. Installation tip: Square insulation plates, such as AccuTrac® plates, may be helpful in distinguishing them from round Drill-Tec'"" RhinoBond® plates. 6. Use fasteners that are suitable for the purlin type, and ensure that purlins are of the required condition to ensure reliable installation and performance. rn 7. Fasteners used in flashings should be dictated by the substrate. m 8. Special care should be taken when fastening plates, so as not to overdrive or underdrive the N fasteners into the purlins. Overdriving the fasteners will result in a deformation or "cupping" of the plate and will result in an uneven or inadequate bond to the membrane when welded. Under -driving the fastener will result in a loose plate with insufficient clamping force and a protruding fastener head that could cause damage to the membrane during welding and through normal roof traffic. o 2 v Insulation & Flute Filler v 1. The selection of insulation type, thickness, and configuration is the responsibility of the 2 Q architect, engineer, owner, or roof consultant. GAF reserves the right to accept or reject any 3 roof insulation as an acceptable substrate for GAF roof systems. GAF EnergyGuardT"° insulations must be used in roofing systems for which GAF guarantees are sought. Refer to the specific EverGuard° System Manual you are working with for a complete list of approved insulation w boards. Copyright© 2019 GAF • 1 Campus Drive Parsippany, NJ 07054 • www.gaf.com 10, 2 v 12a W 2. Flute Filler Insulation: EPS, XPS, or polyiso insulation may be used to fill in flutes of existing metal roof panels, and should fit snuggly between seams of the existing metal panels. Flute filler insulation thickness should be equivalent to the height of the metal panel seams. a. EnergyGuardT"^ Polyisocyanurate insulation with glass -based facer meeting or exceeding the requirements of ASTM C1289, min. 16 psi (110 kPa) compressive strength. b. Extruded Polystyrene insulation meeting or exceeding the requirements of ASTM C578, Type II nominal 1.5 pound (42 gram/cubic cm) density and minimum 15 psi (110 kPa) compressive strength. c. Expanded Polystyrene insulation with plastic facer meeting or exceeding the requirements for ASTM C578, Type II nominal 1.5 pound (42 gram/cubic cm) density and minimum 15 psi (110 kPa) compressive strength. Use the minimum number of fasteners necessary to hold insulation boards in place prior to membrane attachment. Membrane Installation — Mechanically Attached Roofing System into Purlins Membrane Placement Place roof membrane so that wrinkles and buckles are not formed. Remove any wrinkles or buckles from the sheet prior to permanent securement. Roof membrane must be mechanically fastened after it is rolled out, followed by welding to adjacent sheets. Overlap roof membrane a minimum of 6" (152 mm) for side laps of mechanically attached systems, and a minimum of 3" (76 mm) for end laps. Membranes are provided with lap lines along the side laps; the inside line is for mechanically attached system overlaps, which are 6" 152 mm) for TPO membranes. For PVC membranes, the solid line (overlap line) is marked on the top ply 5" (127 mm) from the sheet edge. The fastener line is a nominal 2" (51 mm) from the sheet edge, and an "X" is placed between the sheet edge and the field seam overlap line with spacing every 6" (152 mm). TPO fastener spacing marks should resemble a "pyramid" pattern. Best practice is to install membrane so that the flow of water is parallel or over the side laps toward drainage points. Membrane Securement The Mechanically Attached Metal Retrofit System secures the membrane by mechanically fastening into purlins with Drill-Tec'm Purlin Fasteners as required by the Attachment Tables in this Guide. The fasteners are installed into the purlins for maximum uplift resistance. 2. Depending on sheet orientation and placement of the fasteners into the purlins, fasteners may be located in the seams of the membrane or in the field of the sheet. Fasteners not located in the seams should be covered by an 8" (203 mm) wide flashing strip hot air welded to the membrane. Fasteners must be installed to achieve the proper embedment depth. Install fasteners vertical to the substrate/deck, without lean or tilt. Do not over- or under -drive fasteners. Install fasteners Copyright© 2019 GAF • 1 Campus Drive Parsippany, NJ 07054 • www.gaf.com so that the plate is drawn down tightly to the membrane surface. Properly installed fasteners will not allow the plate to move (underdriving), but will not cause wrinkling of the membrane overdriving). Fastener pullout tests shall be conducted on the purlins with approved fasteners. Refer to the TPO & PVC Attachment Table for Mechanically Attached Systems in the Guide for complete requirements. 5. Membrane may be heat -welded to EverGuard° coated metal flanges. 6. Membrane must be secured to the substrate within 6" (152 mm) of the base of walls and curbs, at the perimeter and at all penetrations with Drill-TecT" XHD Fasteners and barbed plates with a 12" (305 mm) o.c. maximum spacing. Alternatively, membrane may be extended vertically 3" up walls and curbs and secured to the wall/curb substrate within 2" (51 mm) of the plane of the roof. Use Drill-TecT"° XHD Fasteners and inverted termination bar of type and spacing in accordance with in -lap attachment requirements, with a 12" (305 mm) o.c. maximum spacing. Vertical attachment with seam plates and fasteners may also be used. This alternative detail, including termination bar, is required to be used for pressurized buildings. Membrane Installation — Drill-TeCTm RhinoBond° Roofing System into Purlins Membrane Placement 1. Place roof membrane so that wrinkles and buckles are not formed. Remove any wrinkles or buckles from the sheet prior to permanent securement. 2. Full -width rolls can be installed throughout the field and perimeter of the roof. Half sheets are not necessary. rn 0 3. Overlap roof membrane a minimum of 3" (76 mm) for end laps of EverGuard° PVC and TPO m membranes. Membranes are provided with lap lines along the side laps; the red line is for the Drill-TeCT' RhinoBond® Attachment System. PVC does not have an adhered line. t a 4. Best practice is to install membrane so that the flow of water is parallel or over the side laps toward drainage points Membrane Securement o v 1. The RhinoBond° Purlin Attachment Metal Retrofit System secures the membrane to the purlins without penetrating the roofing material. 2. The Drill-TecT°° Purlin Fasteners are installed into the purlins for maximum uplift resistance without being placed in the seams of the membrane. Once the fasteners are in place, unroll the membrane and weld the membrane to the specially coated RhinoBond® plates using the Drill- y TecT"" RhinoBond® induction welding tool. Then, hot air weld the membrane seams. Copyright© 2019 GAF - 1 Campus Drive Parsippany, NJ 07054 - www.gaf.com 0 0s v v w Fastener pullout tests shall be conducted on the purlins with approved fasteners. Refer to the TPO & PVC Attachment Table for Drill-TecT"" RhinoBond° Systems in the Guide for complete requirements. 4. Since fastening patterns are different in the field, perimeter and corner areas, treat each as a separate zone and weld each zone separately. This helps ensure that all plates are welded as you move from zone to zone. Refer to the TPO & PVC Attachment Table for Drill-Tec'm RhinoBond° Attached Systems in this Guide. Roof membrane must be mechanically secured at the perimeter, at the base of internal walls and curbs, and at all penetrations with Drill-Tec'" RhinoBond° Plates and XHD Fasteners at 12" 305 mm) o.c. maximum spacing. Membrane may be heat -welded to coated metal flanges. A minimum of 4 fasteners per penetration is required. Note: This assembly must be placed no closer than 4.5" (113 mm) from vertical flashings and a maximum of 6" (152 mm) away to facilitate the proper placement of the RhinoBond° induction welder. Specific details are available for these conditions in this Guide. Alternatively, standard mechanical base attachment can be used 12" (305 mm) o.c. Fasteners must be installed to achieve the proper embedment depth. Install fasteners vertical to the substrate/deck, without lean or tilt. Do not overdrive or underdrive fasteners.

Drag Load: Drag load is a load that runs parallel to a sloped roof surface. With low -slope roof systems (i.e., 2:12 or less), the effect of drag load typically is insignificant. However, drag loads can pull metal roof panels down the slope of a roof. Factors that contribute to drag load are the weight of the roof system itself, and the additional weight of snow and ice. Drag load increases as roof slope increases. With a single -ply membrane retrofit system, drag loads are resisted by: o Attachment of the metal roofing panels to the structural purlins; Drag loads may be large enough to cause structural purlins to "roll." o Lateral loading on the membrane fasteners. The greater the insulation depth, the greater the bending load on the fasteners. Purlin Continuity: The most common purlin types are "Z" and "C" shaped sections. In many metal buildings, purlins are continuous over rigid steel frames or rafters, which serve as structural supports for the purlins. Purlins are commonly lapped at the supports to achieve continuity. With "Z" purlins, purlins are typically lapped by nesting one inside another, see Figure 2. However with "C" purlins, purlins often are connected back-to-back for continuity, see Figure 3, and under these circumstances, a straight row of fasteners will not be achievable. Where the "C" purlins are installed back-to-back, GAF recommends appropriate measures be taken, so that adjustment is made in the fastening pattern to ensure the attachment of the roofing system engages into the structural purlins.

In metal buildings, purlins should be braced to guard against bending, rotation or deformation. Special attention should be paid to metal panel roofing systems with exposed fasteners, a.k.a. through -fastened metal roofs. With these types of applications, the metal panels are often relied upon to provide the diaphragm action to stiffen the building and brace the purlins. This may not be adequate for a metal roof retrofit. GAF recommends a licensed design professional be retained to evaluate the needs for the specific project. GAF recommends purlins be braced when installing a mechanically attached single -ply over an existing metal panel roof system. See Figure 4 for examples of bracing.

Since the water is confined to individual panel sections, this results in a uniform load on the structural system. Metal buildings are typically designed for balanced loading; therefore, equal loading across the purlins is critical. When a single -ply membrane is installed over a metal panel roof system, the water flow pattern is changed, because water is no longer confined by the panel seams. Certain conditions can lead to ponded water, which may produce uneven loading of the structure. The following may contribute or exacerbate uneven loading situations due to ponding: Clogged gutters or scuppers, especially buildings with parapets or built-in (internal) gutters Surge of water as a result of a mechanically -attached single -ply membrane billowing from high winds Damaged or overloaded purlins Deflection in metal roof panels Copyright© 2019 GAF • 1 Campus Drive Parsippany, NJ 07054 • www.gaf.com I Available Roll Sizes The following is a list of available roll sizes by product type: m 0N m v a v= 2 v v L W Copyright© 2019 GAF • 1 Campus Drive Parsippany, NJ 07054 • www.gaf.com s Product Membrane Thickness Available Roll Size width x length) 50and 60mils 10'x100'(3.05x30.5m) EverGuard® PVC 80 mils 10'x80'(3.05x24.4m) 50and 60mils 10'x100'(3.05x30.5m) EverGuard® PVC KEE 80 mils 10'x80'(3.05x24.4m) 45and 60mils 6'x100'(1.83x30.5m) 8'x100'(2. 44x30.5m) EverGuard® TPO 10' x 100' (3.05 x 30.5 m) 12'x100'(3. 66x30.5m) 80 mils 10' x100'(3.05x30.5m) 50and 60mils 8' x100'(2.44x30.5m) EverGuard Extreme® TPO 10' x 100' (3.05 x 30.5 m) 70and 80mils 10'x100'( 3.05x30.5m) C Roof Design GAF does not practice architecture or engineering. This section is provided for guidance purposes only. There are many factors that may affect roof design, including specific job site conditions, local building codes, building use, etc., which must be taken into account. GAF recommends consultation with a design professional to determine specific roofing needs and requirements for each particular project. Proper roofing system design and selection requires the consideration of many factors. Although GAF's expertise is in materials manufacturing, and not in engineering, architecture, or specialized roof consulting, our company has decades of experience in the practical aspects of roofing. Our experience suggests that careful consideration of the following will provide a fundamentally sound basis for design and selection of EverGuard® TPO/PVC Mechanically Attached and Drill-TecT" RhinoBond' single -ply roofing systems. Re - Cover The basis for any re-cover project is to eliminate defects in the existing roof assembly so that their effect on the new roofing system is minimized. At a minimum, attention to the following considerations is recommended: Raise all perimeter flashings, penetrations, and equipment to provide required flashing heights; Address drainage deficiencies to provide positive drainage; and Concentrate on thorough surface preparation. Existing Metal Roof System As The Substrate It is the responsibility of the engineer, architect, building owner, or roofing contractor to determine the fitness of an existing metal panel roof system that will be serving as a substrate for a specific roofing system installation. Additionally, GAF is not responsible for moisture related problems associated with any deck or substrate materials. Fire Resistance Exterior Fire Resistance: Resistance by the roofing system to fire applied to the exterior roof surface is important. Typically, a UL Class A or B rating is required by building code. Interior Fire Resistance: Depending on the building's use and occupancy, and construction type, resistance to fire from within the building will be required. This is normally expressed in the form of hourly ratings, and usually requires the use of a tested roof assembly. Refer to current EverGuard° listings in the appropriate UL directory or Factory Mutual Approval Listings to verify roof assembly requirements for specific fire ratings. Copyright© 2019 GAF • 1 Campus Drive Parsippany, NJ 07054 • www.gaf.com Thermal Barrier Requirements: The International Building Code has requirements when foam plastic insulation (e.g., polyiso) is used in a roof assembly. A thermal barrier is required to separate the foam plastic insulation from the interior of a building except when a roof assembly passes one of the following tests: FM 4450, "Approval Standard for Class 1 Insulated Steel Decks Roofs' NFPA 276, "Standard Method of Fire Test for Determining the Heat Release Rate of Roofing Assemblies with Combustible Above -Deck Roofing Components" UL 1256, "Standard for Fire Test of Roof Deck Constructions" Wind Performance Ideally, roofing systems should be capable of resisting the forces generated by the maximum anticipated wind speed for a specific building. One widely accepted method for specifying wind performance is to require the appropriate FM 1-60, 1-90, or other rated system as appropriate for a specific building based upon location, exposure, and other factors. The following are common standards and approvals typically used in conjunction with wind performance of EverGuard° roofing systems: Factory Mutual Approvals Testing based on method described in Approval Standards 4450 and 4470. Measures resistance to upward pressure applied to the roof system. American Society of Civil Engineers (ASCE) document ASCE 7, "Minimum Design Loads for Buildings and Other Structures" A comprehensive analysis of wind forces acting on buildings. Requires detailed calculations to determine actual wind pressures at different regions of the roof. Referenced by building codes. rn Corner and Perimeter Attachment: Additional fasteners are required in corner and perimeter areas of o the roof, because wind pressures are increased in the corners, with somewhat lower increased m pressures acting along the remaining roof perimeter. The following details may be used as a fastening v guide for corner and perimeter zones: a Detail 101F: Purlin Fastening Zones — Drill-TeCTm RhinoBond° Assemblies Detail 101G: Purlin Fastening Zones — Mechanically Attached Assemblies Every Purlin Detail 101H: Purlin Fastening Zones — Mechanically Attached Assemblies Every Other Purlin . 0 b Wind Load for Metal Roof Retrofits: TPO/PVC mechanically attached retrofit roofing systems over metal panels on metal buildings should be attached to existing purlins, not the metal panels, to ensure a proper wind -uplift load path. See Figure 1. For conventional mechanically attached roofing systems, they may be fastened into every purlin (e.g., every 5 feet [1.52 m]) or fastened into every other purlin e.g., every 10 feet [3.05 m]). For Drill-TecT"" RhinoBond® attached roofing systems, they should be fastened into every purlin. vL uiW Copyright© 2019 GAF • 1 Campus Drive Parsippany, NJ 07054 • www.gaf.com 0 TPO/PVC PURLIN ATTACHMENT TABLE MECHANICALLY ATTACHED SYSTEMS Maximum roof slope = 2:12 Maximum building height = 40 feet (18.3 m) Maximum enhanced wind speed coverage available: up to 72 mph, on eligible projects only; advanced written approval from GAF required.* Max.
