FAQs
What causes the dark streaks on roofs in Cumberland Gap, and how do algae-resistant shingles solve the problem?
The streaks are mainly caused by Gloeocapsa magma, a blue-green algae that thrives in the humid, shaded conditions common in the Cumberland Gap region. Algae-resistant shingles are manufactured with copper-infused granules that slowly release copper ions whenever it rains. Copper is toxic to algae, preventing growth and eliminating the unsightly stains for 20-30 years, depending on the product.
How are algae-resistant shingles different from standard asphalt shingles?
Both products use the same asphalt/fiberglass base, but algae-resistant shingles incorporate 6–12 % copper-coated ceramic granules across the exposure surface. These granules are evenly blended at the factory, so the shingles look identical to conventional architectural shingles while offering built-in algae protection. Standard shingles lack the copper component and therefore allow algae to colonize the roof surface over time.
Will algae-resistant shingles match my existing siding and exterior color scheme?
Yes. Leading manufacturers such as GAF, Owens Corning, and CertainTeed offer algae-resistant technology in all their most popular color blends—charcoal, weathered wood, slate, etc. Because the copper granules are microscopic, they don’t change the shingle’s visible hue. During a free consultation we bring full-size samples so you can compare the shingle colors against your vinyl, fiber-cement, or wood siding to ensure a cohesive appearance.
What is the expected service life and warranty on algae-resistant shingles installed in Cumberland Gap?
Architectural algae-resistant shingles typically carry a 25- to 50-year limited lifetime warranty on manufacturing defects and a 10- to 15-year warranty specifically covering algae discoloration. In our climate, you can expect a real-world lifespan of 25-35 years with proper attic ventilation and annual maintenance. We register every roof installation so homeowners receive the full transferable manufacturer warranty plus our own 10-year workmanship guarantee.
Can algae-resistant shingles be installed over my existing roof, or is a full tear-off necessary?
Building code allows a second roof layer if the decking is sound and the current shingles are flat. However, we usually recommend a complete tear-off in Cumberland Gap for three reasons: 1) It lets us inspect/repair any hidden decking damage caused by moisture. 2) It eliminates excess weight, extending rafter life. 3) It maximizes the copper granules’ exposure to rainfall for optimal algae protection. After the old shingles are removed, we install a synthetic underlayment and high-flow ridge vent before laying the algae-resistant shingles.
Do algae-resistant shingles cost more, and will they save me money over time?
Expect a material upcharge of about $0.15–$0.25 per square foot, or roughly $300–$600 on an average 2,000-sq-ft roof. Installation labor remains the same. Over time, homeowners recoup that small premium by avoiding periodic chemical roof cleanings (typically $250–$400 each) and by preserving curb appeal, which boosts resale value. The copper-infused shingles also reduce the risk of moisture wicking under the tabs, indirectly extending roof life and delaying full replacement costs.
