TEK Industries stone-coated steel: spec sheet and questions to ask when comparing brands

When you compare stone-coated steel roofing brands, put each manufacturer's own published specification side by side. Below is TEK Industries' published spec sheet, followed by the questions to ask every brand you are considering.

We don't list other manufacturers' numbers here. If you are weighing TEK against brands such as DECRA, Westlake or Tilcor, check each item below against that brand's own current published sheet.

TEK spec sheet (from tekroofingsystems.com)

• Core: 28-gauge steel with a corrosion-resistant aluminum zinc coating

• Insulation: USA-made foam insulation insert in every panel, adding R-value and absorbing rain sound

Questions to ask every brand

• What gauge is the steel core, and what coating protects it?
• What hail class does every product carry, and under which test standard?
• What wind speed is the product rated for?
• Is an insulation insert included in every panel, or sold separately?
• Are fasteners exposed or concealed, and on which profiles?
• Is the warranty a materials warranty, a workmanship warranty, or both? How many years, and is it transferable to the next owner?
• Does the manufacturer supply documentation for HOA approval and for insurance carriers?

Frequently asked questions

What hail rating does TEK carry?

Class 4 / UL 2218. A panel must withstand a two-inch steel ball fired at 90 mph without cracking, splitting or perforating. Every TEK product earns it.

How much does a TEK panel weigh?

TEK Metal Tile weighs 1.4 lbs per square foot. TEK's comparison table lists traditional tile at 9–12 lbs per square foot.

Is a TEK metal roof loud in the rain?

Every TEK panel includes a foam insulation insert that absorbs rain impact. TEK says homeowners report their roof is as quiet as or quieter than their old asphalt shingles.

Is the TEK Lifetime Limited Warranty transferable?

Yes. It is transferable to a subsequent owner during the warranty period.

Manufacturer vs workmanship warranty: which one is TEK's?

TEK's warranty covers the materials. Installation workmanship coverage is provided separately by your TEK certified installer.

How long does stone-coated steel last vs asphalt?

TEK's comparison table gives asphalt shingles 15–20 years and lists a much longer service life for its stone-coated steel; check the current figure on tekroofingsystems.com.
