ASC Building Products

ASC metal roofing and siding gives homeowners and builders standing seam roofing and exposed-fastener panels for roofs and walls. Skyline Roofing is the standing seam line. Nor-Clad and Nu-Wave Corrugated handle either roofing or siding, making them useful lines to compare when your project includes both.

ASC Building Products is a division of ASC Profiles LLC. The company has manufactured metal roofing and siding for more than 50 years. Its siding range serves residential, commercial, and agricultural projects.

Choosing the panel for the job

Skyline Roofing belongs on your list when you want a standing seam roof. Settle the roof’s pitch and support requirements before choosing by appearance. On a shallow roof, water moves off more slowly and the panel’s joint details matter. ASC gives minimum roof-pitch requirements in each product’s installation guide.

For a shop with metal roofing and siding, Nor-Clad and Nu-Wave Corrugated let you use one profile across both surfaces. That gives the building a consistent rib pattern. The roof and walls each need their own trim and installation details.

Delta Rib and Delta Rib III offer exposed-fastener ribbed panels for roofing and siding, and Strata Rib also serves both applications. Compare the rib pattern across the whole wall: what looks subtle on a sample repeats across every panel. For unpainted metal siding, IronOx is a dedicated siding option.

Structural and fire performance

Both panel families have structural and fire verification behind them. ASC states that all its products are independently verified to meet building-code structural and fire-resistance properties, and it expressly includes its thru-fastened profiles.

The installation matters here. ASC’s Class A fire-rating claim for standing seam depends on installation over a non-combustible deck or framing under the applicable requirements, or installation as part of the specified tested assembly. Match the selected panel’s documentation to the job’s deck, framing, and assembly details.

Fasteners and finish choices

Exposed fasteners pass directly through the panels into the structure, so each attachment needs care. Fastener selection and placement matter, and a sealing washer needs controlled compression. Follow the selected panel’s fastening details and the fastener manufacturer’s tightening instructions.

Choosing a color before settling the panel and gauge can force a change later. ASC’s color inventory varies by manufacturing facility and gauge. Your final color choice needs to match the required gauge and supplying facility.

Select standing seam products feature a limited lifetime finish warranty, and Dura Tech xl has a limited lifetime residential warranty. Match the warranty to your exact panel and finish using the version in effect when the material is originally installed.

Plan on regular washing, including the undersides of weather-exposed panel overhangs. ASC recommends an immediate clear-water rinse. Follow the selected finish’s cleaning instructions, including care of the overhang undersides.

Frequently Asked Questions

What is ASC Building Products’ Skyline Roofing?

Skyline Roofing is ASC Building Products’ standing seam metal roofing line. You need to match the panel to your roof’s pitch and support requirements before settling on a finish.

Can ASC metal panels be used for both roofing and siding?

Nor-Clad, Nu-Wave Corrugated, Delta Rib, Delta Rib III, 2½-inch Corrugated, and Strata Rib are intended for roofing and siding. You can carry a profile across both surfaces, but the roof and walls still need their own installation details.

Does ASC standing seam roofing have a hail-impact rating?

ASC’s standing seam products have a Class 4 impact-resistance rating. That’s an impact-test rating, so it doesn’t mean your roof is guaranteed to stay dent-free in every hailstorm.

What does the limited lifetime finish warranty mean?

Select ASC standing seam products have a limited lifetime finish warranty, and the exact panel and finish determine which terms apply. Under ASC’s limited-warranty terms, coverage belongs to the named original homeowner, isn’t transferable, and requires registration within 150 days of shipment. You need the warranty version in effect when the material is originally installed.
