John's Roofing and Siding | Roofing Services in Latrobe, PA 15650

In our area, moss holds moisture against shingles, and poor attic ventilation can trap damp air, leading to insulation issues. Our roof replacement process includes a full tear-off to remove compromised materials, followed by installing a proper ventilation system and synthetic underlayment for an added moisture barrier. We also treat the new roof with zinc or copper strips at the ridge, which gently wash down with rain to inhibit future moss growth, providing a comprehensive solution.

Preventing attic moisture starts with proper airflow. During a new roof installation, we carefully calculate and install a balanced ventilation system—intake at the eaves and exhaust at the ridge—to create a continuous flow of air. This venting, combined with high-quality, breathable synthetic underlayment, helps expel warm, moist air from your attic before it can condense and soak your insulation, protecting your home's energy efficiency and structure.

It depends on the extent of the damage. Moss can lift shingles, allowing water underneath. We'll provide a free, honest inspection at your Latrobe home. If the moss is superficial and the roof deck is sound, a professional cleaning and treatment may suffice. However, if the moss has caused widespread granule loss, curling shingles, or leaks, a roof replacement is often the more reliable, long-term investment to prevent recurring issues and protect your home.
