Drews Roofing And Contracting | Roofing Services in Leesport, PA 19533

Leesport's weather, with its freeze-thaw cycles and humidity, can cause underlayment to degrade over time, leading to leaks. At Drews Roofing, we start with a thorough inspection to locate any compromised areas. We then carefully remove the affected shingles, replace the damaged underlayment with high-quality, water-resistant materials, and re-install the shingles with precision to ensure a watertight seal and long-term protection for your home.

Those dark streaks are often Gloeocapsa magma algae, which thrives in our humid climate. We strongly advise against high-pressure washing, as it can damage shingles. Our professional method involves a gentle, low-pressure application of an EPA-approved, biodegradable cleaning solution specifically formulated to kill the algae at the root and lift the stains without harming your roof's granules or voiding manufacturer warranties.

It depends entirely on the extent and location of the damage. Our expert team will provide an honest assessment. If the damage is localized and the surrounding shingles are in good condition, a targeted repair is often a cost-effective solution. However, if the underlayment failure is widespread or the shingles are nearing the end of their lifespan, a full replacement may be the more prudent, long-term investment to prevent future issues.
