Common signs include sagging roof areas, dark stains or streaks on your ceilings, a musty smell in the attic, and visible water leaks, especially after heavy rain. Roof deck rot is often caused by trapped moisture from failing shingles or flashing. If you notice any of these, it's crucial to get a professional inspection quickly to prevent structural damage.

In Dallastown, flashing around chimneys, vents, and valleys can separate due to age, extreme temperature changes, or improper installation. This creates a direct path for water to enter your home. We repair or replace the flashing using durable, code-compliant materials and expert sealing techniques to re-establish a watertight seal, protecting the vulnerable areas of your roof.

It depends on the extent of the damage. During our inspection, we assess the affected decking. If the rot is localized, we can often remove the damaged section and replace it, then overlay with new underlayment and shingles. However, widespread rot compromises the roof's structure, making a full replacement the safest, most cost-effective long-term solution for your home.
