Questions

Commercial roofing questions, answered

What building owners and managers ask before they call.

Low-slope commercial roofs with rooftop HVAC units
Is the roof inspection really free?

Yes. The inspection costs nothing, and you get what we found and the price explained before any work starts.

Should I repair my flat roof or replace it?

It depends on how much of the roof is worn or holding water, and how far the damage has spread underneath. The inspection tells you which one you need, and why. “They were up front about the process and costs and held true to that throughout the new roof project.” (Andy A.)

How much does a commercial roof cost per square foot?

It depends on the membrane, the insulation, how many layers come off, and the roof's size and access. You get a number for your building after the free inspection, not a guess before it.

TPO or EPDM: which membrane is better?

TPO is a single-ply membrane, usually white, with heat-welded seams. EPDM is a black rubber membrane. Which one suits your building depends on the roof, and we'll explain the choice at the inspection.

Will you help with an insurance claim after storm damage?

Yes. If hail or wind damaged the roof, we help with the claim, including when the insurer pushes back. 30 of our Google reviews mention insurance help.

Do you clean up after the job?

Our customers say so. Eight Google reviews mention the cleanup or the nail sweep. “They left the area so that you would never know that anything was done except for the look of the roof.” (Scott D.)

Do you roof homes too?

Yes. Most of our work is home roofing, from repairs to full replacements, and the same free inspection comes first.

What areas do you serve?

Greenville and the Upstate, from our office at 1801 Rutherford Rd in Greenville. That includes Spartanburg, Anderson, Greenwood, Simpsonville, Greer, Easley and Travelers Rest.

Ready when you are

Book a free inspection, or call and we'll set a time. Flat roofs hide their leaks well, so it pays to look before the ceiling tiles tell you.
