IMPORTANT NOTICE

Be sure to read this manual in its entirety before beginning installation.
This manual is provided to the customers of ASC Building Products as a guide to assist in the installation of Skyline Roofing. Use for any other purpose is prohibited. This manual remains the property of ASC Building Products.
These instructions contain suggested application procedures only and cannot replace the need for good common sense and experience. Responsibility for conformance to state and local building codes, as well as any other applicable project requirements rests with the installer, as does the responsibility to observe reasonable safety procedures.
Certain panel and flashing conditions such as panel overhangs, gutters, rake trim, etc., are easily damaged if a ladder is leaned against them . Care should be taken to avoid this.
ASC Building Products assumes no responsibility for any problems which might arise as a result of improper installation or any personal injury or property damage that may occur with the product’s use.

Notes:
It is recommended that Skyline Roofing be applied on roofs with a minimum 3:12 slope.

Panels exceeding 40' in length must be fastened using the Skyline Roofing clip. Thru-fastening these longer length Skyline Roofing panels is not recommended. For applications requiring the Skyline Roofing clip and also exceed 20 psf of snow load, please contact an ASC Building Products' Representative for installation assistance.
Each trim or flashing in this guide has been assigned a part number. Each part number contains one or two letters followed by one or two numbers (example: EW17). These part numbers have been provided to make ordering these trims and flashings quick and easy.
To prevent mis-alignment of fasteners and “walking" drill bits, it may be advisable to pre-drill certain flashings before they are installed.

IBC/IRC Building Code Compliance Report: Evaluation Report #ER-0309

DELIVERY, HANDLING AND STORAGE	SAFETY CONSIDERATIONS

Always check the shipment upon delivery. Check for damage and check material quantities against the shipping list. Note any damaged material or shortages at the time of delivery.
Handle panel bundles and individual panels with care to avoid damage. Longer bundles and panels may require two or more "pick points," spaced no farther than 10' apart, to avoid damage that can result from buckling and/or bending of the panels.
Store the panels and other materials in a dry, well ventilated area and away from traffic. Elevate one end of the bundle so that any moisture that may have accumulated during shipping can run off. Be sure that air will be able to circulate freely around the bundles to avoid the build-up of moisture. Never store materials in direct contact with the ground.
Note: Excessive storage periods or poor storage conditions often result in water intrusion.
Prolonged exposure to wet conditions can cause paint blistering and galvanized substrate
corrosion or staining in as little as two weeks.

Painted panels are shipped with a protective plastic sheeting or a strippable film coating between all panels. Remove any strippable film coating prior to installation and in any case, do not allow the strippable film coating to remain on the panels in extreme heat, cold, or in direct sunlight or other UV source.

Wear clean cotton gloves when handling unpainted bare panels or flashings to avoid discoloration. Roll forming die marks (which appear black), particularly at bends, will be visible.
Wear clean, non-marking, soft soled shoes when walking on the panels to avoid shoe marks or damage to the finish. Do not step on the panel seams or ribs. Step only in the flat area of the panel.

Never use unsecured or partially installed panels as a working platform.
Do not walk on panels until they are in place on the roof and all of the fasteners attaching the panels to the roof have been installed.

Metal roofing panels are slippery when wet, dusty, frosty or oily.
Do not walk on a metal roof when any of these conditions are present. Wearing soft soled shoes will help minimize slipping and help prevent damage to the painted surfaces.

Do not walk on the panel seams.
When walking on the fully installed roof panels, be sure to step only in the flat areas of the panels.

Always be aware of your position on the roof relative to your surroundings.
Take note of the locations of roof openings, roof edges, equipment, co-workers, etc.

Always wear proper clothing and safety attire. Wear proper clothing when working with sheet metal in order to minimize the potential for cuts, abrasions, and other injuries. ASC Building Products recommends safety glasses and gloves.

Use care when operating electrical and other power equipment.
Observe all manufacturer’s safety recommendations.

Roof installation on windy days can be dangerous. Avoid working with sheet metal products on windy days.

SKYLINE ROOFING PANEL PROFILE

Use only those accessories specifically designed for use with this product . Use only galvanized or Zincalume coated flashings. Isolate roofing and flashings from contact with dissimilar metals.

Note: All flat metal surfaces can display waviness commonly referred to as "oil canning". This is caused by steel mill tolerances, variations in the steel substrate and roofing underlayments. Oil canning is an inherent characteristic of flat steel products, not a defect, and therefore is not a cause for panel rejection.

16" Coverage (12" Optional)

Important Note:
At completion of each day’s work and at completion of roof installation, sweep panels, flashings, and gutters clean. Take special care not to sweep metal shavings down into the gutters. Do not allow fasteners, cuttings, filings, or scraps to accumulate.

Available Products:
Coverage	Gauge	Weight (lb/ft2)

16"	24	1.2	
12"	26	1.0	

MINIMUM RECOMMENDED TOOLS & EQUIPMENT
Screws/Screw bits: Clutch type screw gun with depth locating nose piece allowing variable torque settings is recommended to insure proper installation of the screws. The following bits will be required: 1/4" hex and No. 2 Phillips screwdriver bit.
Snips: For miscellaneous panel and flashing cutting requirements. Three pairs will be required for left edge, right edge, and centerline cuts.
Electrical Metal Shears or Nibblers: Used for general metal cutting, such as at the hips and valleys.
Chalk Line: Used to assist in the alignment of panels, flashings, etc.
Caulking Gun: For miscellaneous caulking and sealing to inhibit water infiltration.
Rivet Tool: Used for miscellaneous flashing and trim applications.
Turn-Up Tool: Available from ASC Building Products, the tool is used to hand brake the ends of the panels as indicated within the installation details.

Marking Tools: Indelible marker or scratching tools. Scratch Awl: Used to mark the steel.
Utility Knife: Used for miscellaneous cutting.
Electric Drill: Used to drill holes such as those required for rivet installation.
String Line: Used for general alignment and measuring.

Tape Measure: 25 ft. minimum (another 50 ft. handy).
Locking Pliers: Standard and "Duckbill" style for miscellaneous clamping and bending of parts.

Note: Some installers prefer to use circular power saws with metal cutting abrasive blades. While the use of power saws may be faster, there are some disadvantages that must be considered: (1) The edges of metal that have been saw cut are jagged and unsightly, and are more likely to rust than sheared edges. (2) Saw cutting will leave small particles of metal on the panel surface that will rust and damage the panel finish if not
completely removed.

Hammer: Used with roofing nails to fasten flashings.

ROOF PREPARATION

ASC Building Product's Skyline Roofing can be used in both new construction and retrofit roofing applications. Skyline Roofing must be installed over a continuous rigid substrate such as plywood, or OSB. All substrates must be complete, accurately sized and located, in true plane, secure and otherwise properly prepared.
Contact ASC Building Products for additional information .
The following steps need to be taken to prepare the roof for installation of Skyline Roofing panels:
New Roofs:

Make sure there are no nails or other objects protruding from the substrate that might puncture the underlayment or the roof panels. Clean all debris from the roof.
Check all details for possible roof penetrations which must be added to the deck prior to roof panel installation.
Cover the entire roof deck with minimum 30 lb. asphalt saturated felt paper. Some synthetic underlayments may be used in place of felt with ASC Building Products' Skyline Roofing. Installer must ensure they meet the minimum standards of 30 lb felt and that the underlayment manufacturer has approved them for use with metal roofing. (Check with an ASC Building Products representative if project is in snow country). For Class A fire resistance, see notes below. For installation, begin at the eave and roll the underlayment horizontally (parallel to the eave). Allow each consecutive course to overlap the previous one 3". Overlap the ends a minimum of 6" when starting a new roll of underlayment. (See Figure 1). Areas of underlayment that have torn should be replaced or repaired prior to installation of the metal roof.

Constructions Requiring Class 'A' Fire Resistance:
Panel: ASC Building Products’ Skyline Roofing steel roof panels.
Barrier Sheet (one of the following):
GAF VersaShield Underlayment
Polyglass Polystick XFR
Georgia-Pacific DensDeck Roofboard

Additional Ply Sheet (optional): Any UL-classified Type G1, G2 or G3 base/ply sheet, Type 15, 20 or 30 felt or UL-classified prepared roofing accessory or ASC Building Products' "AEP Span Underlayment HT"
Substrate: 15/32” min. plywood or OSB.

Notes:
Obey all local code requirements.
Class A assembly requirements noted above per UL listing #TGFU.R21182. Refer to UL listing for specific construction limitations.

Place an alignment line along the gable end where the first roof panel will be installed. THIS LINE MUST BE LOCATED 1/4" IN FROM THE GABLE EDGE OF THE ROOF DECK AND SQUARE WITH THE EAVE LINE (See Figure 2).
Various methods exist for insuring that the line is square. Call your ASC Building Products representative if you need assistance.

Note: Check with the underlayment supplier for specific installation and handling instructions. Over exposure to the environment may cause buckling of the underlayment resulting in an objectionable appearance of the installed roof.

EXISTING ROOFING:

Some jurisdictions will allow reroofing over existing roofing without the need for tearoff. Check with your local codes or building department for your specific requirements.
For best results, Skyline Roofing requires a smooth and flat substrate. Application over rough and/or uneven surfaces is not recommended. If the roof is to be stripped down to the existing decking, follow the procedure for new roofs.
Be sure to check the existing roof and repair any damaged areas prior to installation of the new roof system.

Note: Do not apply Skyline Roofing over roofs with structural damage or trapped moisture.

The following steps should be taken when installing ASC Building Products' Skyline Roofing over existing roofing:
Inspect the roof for damage and make the necessary repairs to achieve a flat plane for the metal roof panels.
Secure any warped or loose roofing.
Make sure that there are no nails or other objects protruding from the roof that might puncture the new underlayment or the new roof panels.
Remove all moss and other debris from the roof.
Cut off any overhanging roofing flush with the roof deck and remove all hips, ridge caps, and penetration flashings.
Follow the directions on previous page for roof preparation.

Panel Installation - Fixed Eave Install. Method

GENERAL
Study the details section of this manual prior to the installation of the panels. Pay close attention to the following:
Flashings that need to be installed prior to the panels include valley, eave trims, pre-hung gutters,
chalet gable, adjustable gable, and penetration flashings for skylights, chimneys, etc.

Some panels may require "turn-up" at the uphill end prior to their installation.
Apply caulking to the pre-installed flashings per the instructions in the detail section of this manual.

Notes:
Alternate substrate thicknesses have not been included as they don't provide greater outward wind load capacities. Inward gravity loads (snow, etc.) are also resisted by the substrate therefore substrate thickness must be evaluated to account for these inward loads.
Skyline Roofing panels utilize fastener mounting slots at 11" intervals.
Basic Wind Speed Met is based on 2021 International Residential Code (IRC) code provisions (IRC Section R301.2.1) using the following assumptions: Slope >2:12, Wind exposure =B, Mean roof height ≤ 30’, No topographic effects. These values only apply to projects that fall under the 2021 IRC. For applications beyond the assumptions above, please refer to IRC Section R301.2.1 for necessary adjustments, or consult a design professional for assistance.
Outward Wind Load Capacities are taken from IAPMO-UES Building Code Compliance Report #ER-0309. For projects governed by the International Building Code (IBC), consult the Engineer of Record to determine if stated capacities meet or exceed the project’s outward wind load requirements. The capacities stated in the table can also be used for IRC governed projects.

PROCEDURE FOR INSTALLING PANELS LESS THAN 40 FT. IN LENGTH

Align the female edge of the first panel with the alignment line constructed along the start gable (see pg. 7, item 4). Allow the panel to overhang eave 1" (Figure #3).
Check the uphill end of the panel (see corresponding detail for proper panel position). Make sure the female edge of the panel remains 1/4" from the gable and the overhang is 1" from the eave.

FIXED EAVE DETAILS

After the first panel is properly aligned, tack the gable end to the roof as in Figure #3. Then, fasten the panel along the male edge fastening flange. Refer to Table #1 for the fastener spacing.
Align the second panel female edge with the first panel male edge (Figure #4). Make sure the panels are flush with each other at eave edge. Note: the panels overhang the eave by 1".

1" OVERHANG
Snap the panels together at the seam with light foot pressure. Work the seam together from the eave end toward the ridge. DO NOT work the seam from both ends toward the middle.
After locking the panel seam, fasten the panel to the roof utilizing the fastening flange along the male edge (Figure #4).

Panel Installation (continued)
Apply consecutive panels as in items #4 through #6 above.
Fasten the panels along the eave with #14 wood screws located along a straight line parallel to the eave and 3" up from the end of the panel. The fasteners should be evenly spaced (See Figure #5).

Procedure:
Locate the panels down from the ridge as required. Provide space between the zee closure "Z17" and the end of the panel to allow for expansion of the panel. Check the overhang at the eave (see pg. 12).
Turn up panel. Caulk the bottom and sides of the polyethylene closure. Set closure as shown in detail.
Attach the zee closure "Z17"(solid) at the top edge of the roof parallel to the ridge.

Fasten the hip/ridge flashing "R16" to the zee using #12 x 3/4" stitch screws (adjacent to the panel ribs).

Note: "R16" is a standard ridge. A narrow ridge, "R18", is also available. If using narrow ridge, field notch with tin snips to fit over ribs. Attach "R18" to the zee closure with color-matched #12 x 3/4" stitch screws @ 12" O.C. adjacent to each panel rib.

Procedure:
Substrate should be held back 2" from each side of the ridge.
Locate the panels down from the edge of the substrate as required. Provide space between perforated zee closure “Z18” and end of panel to allow for expansion of the panel. Check the overhang at the eave. (See pg. 12).
Install foam panel closure at top end of panel. Secure and seal in place with polyurethane sealant.

Attach the perforated zee closure “Z18” at the top edge of the plywood and parallel to the ridge.
Fasten the vented ridge “R17” to the zee closure using #12 x 3/4" stitch screws. (Adjacent to the panel ribs).
Caulk, lap and rivet sequential flashings. (See appendix).
Close the ends of the ridge cap by slitting and folding material at each end, caulking joints, and fastening with rivets (see following page).

Procedure:

Note:
Valley dimensions must be the proper width to account for slope, snow, ice and rain conditions.
An underlayment such as a rubberized
cold-applied membrane is recommended. The membrane is installed first, extending 3'-0" up from the center of the valley on each side, with felt overlapping the membrane.
Refer to applicable building codes to ensure roof valley construction meets code requirements. Certain jurisdictions, like wildfire prone areas, may require different construction methods or materials.

Place a second layer of 36" roof felt in the valley center line with 18" of felt on each side.
Starting at the low end, trim and place the valley flashing "V16" so it overhangs the eaves 1" (see following page).
Caulk and over lap the subsequent valley flashings a minimum of 8".
Parallel to the valley, place row of butylmastic tape spaced as shown.
Field cut the panels holding a minimum of 4" back from
the valley as shown. Larger valleys, without the center V, may be required in snow country installations.
Fasten the panels to the substrate using (4) #14 wood screws, evenly spaced, insert 2" from the end of panel so they align with butyl mastic tape.

For penetrations through the panel sidelap:

When a penetration occurs through the panel sidelap, install gunnable caulk from the penetration location, all the way uphill to the ridge, peak or endwall to prevent water from running downhill into the opening. See detail at left.

FIXED EAVE DETAILS

Procedure:

Note: In many cases it may be easier to locate the vent/ pipe flashing in the flat area of the roof panel (as shown) rather than have the penetration occur at a panel rib.
Penetrations at panel ribs also increase the risk of water penetration. Determining panel layout prior to installation often simplifies penetration flashing installation.

Trim the opening in the flashing to 20% smaller than the pipe diameter.
Slide the flashing down over the pipe.
Seal between the flashing and the roofing with gunnable caulk and set the flashing.
Form the flashing to fit the profile of the roof.
Fasten the flashing with #14 x 1" wood screws at 1" o.c.

Procedure:
Place a second layer of 36" roof felt in the valley center line with 18" of paper on each side.

Notes:
Valley dimensions must be the proper width to account for slope, snow, ice and rain conditions. An underlayment such as rubberized cold-applied membrane is recommended. The membrane is installed first, extending 3'-0" up from the center of the valley on each side, with felt overlapping the membrane.
Foam or metal closures and caulking are required between the intersecting ridge cap and the valley flashing to provide adequate weathertightness.

Caulk and lap the subsequent valley flashings a minimum of 8".
Parallel to the valley, place row of double beaded butyl mastic tape as shown on pg. 17.
Field cut the panels holding a minimum of 4" back from the valley as shown. Larger valleys, without the center V, may be required in snow country installations.
Attach the panels to the roof and 'thru-fasten' along the bottom end using (4) #14 wood screws per
panel evenly spaced so they align with the butyl tape sealant as shown on pg. 17.

Panel Installation - Floating Eave Install. Method

GENERAL
Study the details section of this manual prior to the installation of the panels. Pay close attention to the following:
Flashings that need to be installed prior to the panels include valley, eave trims, pre-hung gutters, chalet gable, adjustable gable, and penetration flashings for

skylights, chimneys, etc.
Some panels may require "turn-up" at the uphill end prior to their installation.
Apply caulking to the pre-installed flashings per the installation details.

Notes:
Alternate substrate thicknesses have not been included as they don't result in greater outward wind load capacities. Inward gravity loads (snow, etc.) are also resisted by the substrate therefore substrate thickness must be evaluated to account for these inward loads.
Skyline Roofing panels utilize fastener mounting slots at 11" intervals.
Basic Wind Speed Met is based on 2021 International Residential Code (IRC) code provisions (IRC Section R301.2.1) using the following assumptions: Slope >2:12, Wind exposure =B, Mean roof height ≤ 30’, No topographic effects. These values only apply to projects that fall under the 2021 IRC. For applications beyond the assumptions above, please refer to IRC Section R301.2.1 for necessary adjustments, or consult a design professional for assistance.
Refer to IAPMO-UES Building Code Compliance Report #ER-0309 as needed for further information.

PROCEDURE FOR INSTALLING PANELS LESS THAN 40 FT. IN LENGTH

Notch 1" at the downhill end of the panel and fold down.
Confirm proper length of panel at both uphill and downhill ends, ensuring panel cleat (or eave trim 'nose') engagement is considered for turned-under downhill edge.
Align the female edge of the first panel with the alignment line constructed along the start gable (see pg. 7, item 4).

After the first panel is properly positioned, affix the gable side of the roof as shown in Figure #3. Then attach the first panel along the nailing flange. Refer to Table #1 for roof fastener spacing.
Align the second panel edge with the first panel edge (Figure #4). Make sure the panels are even with each other along the eave edge.

Snap the panels together at the seam with light foot pressure. Work the seam together from the eave end toward the ridge. DO NOT work the seam from both ends toward the middle.

For penetrations through the panel sidelap:

FLOATING EAVE DETAILS

When a penetration occurs through the panel sidelap, install gunnable caulk from the penetration location, all the way uphill to the ridge, peak or endwall to prevent water from running downhill into the opening. See detail at left.

Procedure:
Trim the opening in the flashing to 20% smaller than the pipe diameter.

Note: In many cases it may be easier to locate the vent/ pipe flashing in the flat area of the roof panel (as shown) rather than have the penetration occur at a panel rib.
Penetrations at panel ribs also increase the risk of water penetration. Determining panel layout prior to installation often simplifies penetration flashing installation.

Slide the flashing down over the pipe.
Seal between the flashing and the roofing with gunnable caulk and set the flashing.
Form the flashing to fit the profile of the roof.
Fasten the flashing with #14 x 1" wood screws at 1" o.c.
