Estate home with a WeatherLok stone-coated steel shake roof

One roof.
Then never again.

Most homeowners buy a new asphalt roof every fifteen years or so, then do it all over again. WeatherLok ends that cycle. Stone-coated steel that outlasts the mortgage, holds up to the worst weather your home could face, and may even lower your insurance bill. You buy it once and stop thinking about your roof.

Why homeowners choose it

Every benefit backed by a hard rating.

110 mph wind

Storm proof

Rated for 110 mph wind, tested and certified. Interlocking hidden-fastener panels lock down as one system. Sheds the kind of wind that tears shingles off in strips.

Class A fire

Fire safe

Class A fire rating, the top class you can get. Non-combustible steel, it will not catch an ember and burn. Real peace of mind if you live in wildfire country.

70-year service life

Built to last

Built for a 70-year service life. Will not crack like tile or rot like wood. Outlasts three asphalt roofs, one after another.

Most of our customers
are replacing an asphalt roof.

Stone-coated steel has been on homes across North America for decades. Here is the difference, line by line.

The difference WeatherLok steel A typical asphalt roof
Roof life Built for a 70-year service life. You buy one roof. 15 to 20 years, then you pay for the whole roof again.
High wind Rated for 110 mph. Interlocked panels hold as one surface. Lifted tabs and blow-offs are how most shingle roofs die.
Leaks Sealed watertight. Five hidden screws per panel, never exposed to weather. Nail pops and lifted tabs are where leaks start.
Hail Class 4 impact rating, independently tested against hail. Cracked and bruised shingles, granules in the gutter.
Fire Class A rated. Steel does not ignite. Asphalt is a petroleum product.
Re-roof day Installs right over up to two layers of existing shingles. Tear-off crew, dumpster in the driveway, disposal fees.

UL tested for impact, fire, and wind. We will hand you the rating documentation on request.

Asphalt is cheap to install once. WeatherLok is cheap to own once.

Comparing standing seam too? It costs more than WeatherLok, it ripples (roofers call it oil canning), the color fades, and it glares in direct sun. The Slate Shingle profile gives you the same clean line with none of it.

Beyond protection

The roof that keeps on giving.

Curb appeal

A fresh-roof look that does not fade, with no metal glare and no oil canning. The kind of roof neighbors ask about.

Increased home value

A roof that protects everything underneath it and looks good doing it. Buyers see a roof they will never have to replace, and that adds real value.

Cooler in summer, warmer in winter

Owners tell us the same thing: the house stays cooler through summer and warmer through winter.

Light on the house. Heavy on the ratings.

Less than half the weight of asphalt on your framing, and it still carries the top impact, fire, and wind ratings, independently tested by UL and ASTM.

No tear-off. No disposal fees.

Up to two layers of existing shingles stay right where they are. No dumpster, no landfill charge, fewer days with a crew on your roof, and less chance of something getting damaged on the way.

The stone stays on the steel

Granules bonded to the panel, not the loose grit you rake out of your gutters every fall.

Your roof may lower your insurance bill.

A Class 4 hail rating and a Class A fire rating mean many insurers give an impact-resistant roof discount. Ask your agent, and we hand you the documentation to send them.
