Q.01Are the black streaks on my roof damage?
They are usually algae, which thrives in humid places like the Mississippi valley. The streaks are mostly cosmetic and can often be cleaned, but they can signal a roof that stays damp. New GAF shingles with StainGuard protection resist regrowth.
Q.02Why is there frost in my attic in winter?
Warm, moist air from the house is reaching the cold roof deck and freezing on the nails. When it thaws it drips onto insulation and ceilings. The fix is air sealing and balanced ventilation, and we check both.
Q.03Which Quad Cities areas do you serve?
All of Davenport, including the Village of East Davenport, McClellan Heights, Vander Veer, Hilltop, and Goose Creek, plus Bettendorf, Moline, Rock Island, East Moline, Eldridge, Riverdale, Le Claire, Blue Grass, Walcott, and Milan. Iowa projects are managed from Centerville.
Q.04Do I need Class 4 shingles in Davenport?
Not always. Exposed bluff-top homes benefit the most, and some insurers offer premium credits for Class 4. Sheltered homes on tree-lined streets often do well with standard architectural shingles. We quote both so you can compare.
Q.05What does GAF Master Elite certification mean?
GAF grants it to about 2% of roofing contractors who meet its licensing, insurance, and reputation standards. It is required to register the 50-year System Plus warranty, and you can verify it on GAF's contractor locator.
Q.06What does a Davenport roof replacement cost?
Most homes run $8,500 to $18,000, and an 1,800 square foot house is often $12,000 to $15,000 in GAF Timberline HDZ. Steep lots, moisture-damaged decking, and new ventilation affect the price. Estimates are itemized, and 0% financing is available through Service Finance Company.
Q.07Can algae or moss be cleaned instead of replacing the roof?
Often, yes, if the shingles underneath are still in good shape. Pressure washing damages shingles, so it should be a gentle treatment. If moss has lifted shingles or the roof is near the end of its life, replacement makes more sense.
Q.08How quickly can you respond to a leak?
Call (608) 909-9109 any time. We prioritize active leaks with temporary cover and photos, then schedule a full inspection of the roof and attic.
Q.09Will insurance cover damage from condensation?
Generally no. Condensation and long-term moisture are usually treated as maintenance, while sudden storm damage is covered. We help separate the two so a legitimate storm claim is not confused with an attic moisture problem.
Q.10How many days does a reroof take in Davenport?
Most homes take a single day, though steep bluff lots can take longer. We protect landscaping, strip to the deck, replace soft sheathing, add ventilation where needed, and magnet-sweep the yard.
