On every project










A roof price depends on the size and pitch, how many old layers have to come off, the material you pick (asphalt shingle, flat membrane, metal), the condition of the decking underneath, and access. We price it after we get on the roof and see it, then put the full scope in a written estimate so there are no surprises. Ask for a free inspection to get real numbers for your roof.
Curling, cracked or missing shingles, granules collecting in the gutters, daylight or water stains in the attic, sagging areas, and a roof past 20 years are all signs. If the damage is localized we repair it; if the deck or a large area is failing, a replacement is the honest call. We tell you which one you actually need.
Most residential re-roofs are one to three days depending on size, weather, and how much decking needs replacing. Flat and commercial roofs vary more. You get a firm timeline in the written estimate before we start.
A quality asphalt shingle roof installed correctly lasts about 20 to 30 years, flat membranes about 15 to 25, and metal longer. Proper flashing, ventilation, and installation matter more than the shingle brand for how long it actually lasts.
