Professional Roofing Repair in Pittsburgh, PA 15210 - Knerr Roofing

Inadequate ventilation traps heat and moisture in your attic, which is common here with our humid summers and cold winters. This can cause ice dams in winter, warp roof decking, drastically reduce shingle lifespan, and spike your cooling costs. Our inspection identifies airflow issues, and we provide solutions like installing ridge and soffit vents to protect your roof.

Moss loves Pittsburgh's shaded, damp environments and can lift shingles, holding moisture against your roof. We never recommend power washing, as it damages granules. Instead, we perform a professional, gentle cleaning with moss-killing solutions and may install zinc or copper strips along the ridge—a long-term preventative measure to inhibit future growth.

Absolutely. Clogged or damaged gutters are a major culprit for both moss and ventilation issues. Overflowing water soaks roof edges and siding, creating a perfect environment for moss. We repair, replace, and clean gutters to ensure proper water diversion, protecting your roof's perimeter and foundation—a key part of a holistic roofing solution.
