Commercial & steel roofing
One roof specified for the building, not off a price sheet.
Commercial re-roofs get Class 3 and Class 4 shingles matched to the structure, and we run steel on new builds and re-roofs where it actually earns its cost.
Commercial roofing: specified against the building, not a catalogue
A commercial roof gets sized up differently than a house. Slope, drainage, foot traffic from other trades, how the building actually gets used day to day, all of it changes what covering makes sense. We spec Class 3 and Class 4 impact-rated shingles against the specific building rather than defaulting to whatever's cheapest to move, and we'll tell you when the extra cost of Class 4 is worth carrying on a commercial structure and when it isn't. Tear-off and decking inspection work the same way they do on a house: the old covering comes off, we look at what's underneath while it's open, and anything soft gets replaced before the new roof goes down.

New build and re-roof
Steel roofing, and when it's worth it
We run steel on new construction and on re-roofs, and it's a genuinely different roof than a shingle system: panels running the length of the slope, fastened and sealed rather than layered course by course. Steel earns its cost fastest on long, low-slope runs where a shingle would be fighting the pitch, on outbuildings, and on any property where the owner wants to stop thinking about the roof for the next few decades.
It is not automatically the right call. A steel roof costs more up front than a shingle roof, and on an ordinary metro house with a normal pitch, a good impact-rated shingle is usually the smarter buy. We'll walk your building and tell you honestly which one we'd put on it, not just the one with the bigger ticket.
The honest version
Steel isn't always the upgrade it sounds like
- Where steel earns its cost
- Long, low-slope commercial runs. Outbuildings, barns and shop roofs. Properties where the owner wants decades between roofs and is willing to pay the higher install cost to get there.
- Where a shingle wins
- An ordinary metro house with a normal pitch. Lower cost up front, and a Class 3 or Class 4 impact-rated shingle already covers the hail risk that matters most in Oklahoma. Most residential jobs land here, not on steel.
