Introduction	Minimum Recommended Tools & Equipment

ASC Building Products' Metal Roofing not only prioritizes weather tightness, durability, aesthetic appeal, and affordability but also emphasizes ease of installation. This guide aims to assist installers in achieving top-quality results. Feel free to reach out to an ASC Building Products representative for any additional assistance you may need.
Important Notice: Be sure to review 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 metal 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 requirements rests with the installer, as does the responsibility to observe reasonable safety procedures.
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 metal roofing be installed on roofs with a minimum slope of 3:12.
The details contained in this guide are shown over a plywood substrate. Details remain essentially the same for either a solid substrate (plywood/OSB or steel decking), spaced framing or intermittent support conditions with only the fastener size & type changing. Where spaced framing is used, perimeter supports for flashings must be considered.
Each flashing part in this guide has been assigned a part number. Each part number contains one or two letters followed by one or two numbers, for example 'EW17'. These part numbers have been added to make referencing these parts easy.

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.

Delivery, Handling and Storage
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.

Safety Considerations
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.

Roof Preparation
ASC Building Products metal roofing can be used in both new construction and retrofit roofing applications. We recommend installing metal roofing over a continuous rigid substrate such as plywood/OSB, or over spaced supports. Contact ASC Building Products for additional information.
The following steps need to be taken to prepare the roof for installation of metal roofing panels:
New Roofs:
Make sure there are no nails or other objects protruding from the substrates 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.

Roof Preparation, cont.

Cover the entire roof deck with a minimum of 30 lb asphalt-saturated felt paper. Many synthetic underlayments may be used in place of felt with ASC Building Products’ roofing. Installer must ensure the underlayment manufacturer has certified their synthetic underlayment for use with metal roofing. For applications over spaced framing, other underlayments/barriers may be required. 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 inches. Overlap the ends a minimum of 6" (see Figure #1). Areas of underlayment that have torn should be replaced or repaired prior to installation of the metal roof.

Place an alignment line along the gable end where the first roof panel will be installed. This line must be parallel to the gable edge of the roof deck and square with the eave line. Check the roof for squareness by making a 3' line across the eave. (see Figure #2). Completing the 3' x 4' x 5' triangle should place the 4' edge of the triangle parallel with the gable. The first roof panel will be placed parallel with this line. Slight variations or out-of-square conditions can be covered by the gable trims. Refer to Gable detail.

Figure 2
It is very important to measure the entire length of the roof from gable to gable. Correct placement of the panels will allow the panel’s ribs on each side to be covered by the gable flashing. This will create a symmetrical appearance on both ends of the roof. Should this be impractical, the Adjustable Gable detail can be used.
Note: In areas where snow, ice, and/or heavy rain

Constructions Requiring Class ‘A’ Fire Resistance:

Panel: ASC Building Products’ steel roof panels.
Barrier Sheet (one of the following):
GAF VersaShield® Underlayment
Holcim Elevate CLAD-GARD™ SA-FR®
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 (TGDY) or ASC Building Products’ “AEP Span Underlayment HT”.
Substrate: 15 ⁄ 32” min. plywood or 7/16” min. 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.

conditions exist, a high temperature cold-applied rubberized underlayment , like AEP Underlayment HT, should be used in lieu of felt in the valleys. Felt on the remainder of the roof will lap over the membrane where the two meet. See Valley detail.
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, roofing requires a relatively smooth and flat substrate. Application over rough and/or uneven surfaces is not recommended, ie, wood shingles. If the roof is to be stripped down to the existing decking (strongly recommended), follow the procedures for new roofs on the previous page. Be sure to check the existing roof and repair any damaged areas prior to installation of the new roof system.
Note: Do not apply metal roofing over roofs with structural damage or trapped moisture.

The following steps should be taken when installing ASC Building Products’ Metal Roofing over existing roofing:

Inspect the roof for damage and make any necessary repairs to achieve a flat plane for the metal roof panels. Wood shingles should be removed.
Secure any warped or loose roofing material.
Ensure that there are no nails or other objects protruding from the roof that might puncture the new underlayment or damage the new roof panels.
Remove all moss and other debris from the roof.

Cut off any overhanging roofing flush with the edges of the roof deck and remove all hips, ridge caps, and penetration flashings.
Metal debris/shavings should be removed from the roof progressively and daily to prevent immediate corrosion and scratching of the metal panel's top coat.
Follow the directions on page 3 for roof preparation.

Notes:
The table above shows the fasteners commonly required for ASC Building Product's roofing panels. Refer to the panel installation details within this guide for specific fastener usage.
Details shown within this installation guide are based on installations over plywood. Other installations may require different fasteners.
Panel attachment screws must be long enough to fully penetrate through plywood/OSB at least 3/8", or penetrate into solid lumber by at least one inch.

	All screws must be coated to provide protection against corrosion.
Exposed fasteners must have sealing washers and should be the same color as the parts they attach.
Roofing nails are also required, but are not furnished by ASC Building Products.
Screws must be properly driven to ensure proper seal and holding strength. Do not underdrive or overdrive the screws.
Stainless steel rivets are not watertight.

Panel Installation

Procedure:
Before installing the roof panels, install any underlying trims, such as eave trims, valley flashings, pre-hung gutters, etc. Refer to individual installation details for clarification.
Align the first panel along the gable eave, using the alignment line marked along the starting gable (see Figure 2). Ensure the desired eave overhang and correct ridge setback are maintained.
Install the inside panel closure at the eave end of the panel.
Fasten the panel to the substrate according to the guidelines provided on page 7. See page 8 for recommended fastener types.
Continue installing panels across the roof, maintaining proper alignment and squareness to avoid a sawtooth effect along the eave.

	Once all panels are in place, complete the installation by adding final trims over the panel edges, including gable trims, ridge caps, and other finishing components. Refer to the installation details throughout this guide for more information.
Notes:
Details shown within this installation guide are based on installations over plywood substrates. Installations over alternate materials (lumber, metal framing, etc) will require some adjustments. Ensure proper fasteners are used for each alternate installation method.
Metal debris and shavings should be removed from the roof frequently, as they can cause corrosion stains and damage the panel's painted coating almost immediately.

Procedure:
Place a second layer of 36" roof underlayment in the valley center line with 18" of roof underlayment on each side.
Starting at the low end, trim and place the valley flashing so it overhangs the eaves 1" (see next page).
Caulk and lap the subsequent uphill valley flashings a
minimum of 8".
Typical polyethylene closures cannot be installed diagonally across a miter cut panel. At mitre cuts, use universal Emseal closures parallel to the center of the valley.
	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.
Install the panels over the valley flashing using #14 wood screws through the Emseal closure strip.

Space panel fasteners no further apart than as shown in Fastener Placement section.
When valleys are required, install sidelap neoprene or butyl mastic tape inside the sidelap a minimum of 10” up from the panel edge.
Notes:
In areas where snow, ice and heavy rain conditions exist, panels may need to be held back more than 4" and the valley flashing overall width must be increased. A high temperature cold-applied rubberized underlayment should be used extending at least 3' up from the center of the valley on each side.
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.

Vent Flashing

VENT PIPE

PIPE FLASHING

FASTEN AT 1" O.C.

ROOF PANEL

GUNNABLE CAULK IN CAPILLARY GROVE FROM RIDGE/HIP TO
UPHILL SIDE OF ROOF PENETRATION

Procedure:
Trim the opening in the pipe flashing to 20% smaller than the pipe diameter.
Slide the flashing down over the pipe.
Seal between the vent flashing and the roof panel with gunnable caulk and set the flashing.
Form the flashing flange to fit the profile of the roof.
Fasten the flashing to the roof with fasteners at 1"
O.C. spacing.
Penetrations occurring over spaced supports may require additional support framing.
A stainless steel band clamp should be installed at the top of the vent/pipe flashing.

Notes:
A minimum drainage clearance of 2" should be maintained between both sides of the flexible vent/pipe flashing base and the roof panels’ major ribs.
When a penetration occurs through a panel sidelap, gunnable caulk needs to be installed in the capillary groove from the penetration to the ridge. This will prevent water from running downhill in the capillary groove and into the roof opening. Refer to detail above.
When a square-based pipe flashing is used, point one corner of the flashing base uphill to better shed water downhill (rotate flashing 45° from what is shown above).

Vent/Pipe Flashing Installation Procedure

STEP 1: Cut
Cut to pipe diameter marked on flasher (this is approximately 20% smaller than the diameter of the pipe).

STEP 2: Slide
Slide the flasher down the pipe, using water to lubricate if necessary.

STEP 3: Form
Form and bend the aluminum base of the flasher to fit the surface of the roof.

		

STEP 4: Seal
Seal the flasher by applying urethane/silicone sealant between the flasher and the roof. Use a large slotted screwdriver to press the base down tightly.

STEP 5: Fasten
Fasten the flasher with weather-resistant fasteners to
complete the seal.	Note: For the best drainage when
a square-based pipe flashing is used, one corner of the flexible pipe flashing should be oriented to the high-side of the roof.
