Common signs include sagging or uneven roof planes, dark stains on your interior ceilings, a spongy feel when walking on the roof, and increased indoor moisture or mold. In our climate, trapped moisture from ice dams or snow is a frequent culprit. We recommend a professional inspection if you notice any of these, as early detection prevents more extensive structural damage.

The underlayment is your roof's critical secondary water barrier, especially vital during Fond Du Lac's heavy rains and snowmelt. It protects the decking if shingles are damaged. It typically needs replacement during a full reroof, or if we find it's torn, brittle, or saturated during an inspection. Using high-quality, ice-and-water shield in vulnerable areas is a standard part of our local best practices to prevent leaks.

We start by safely removing the affected shingles and underlayment to fully expose the damaged decking. All rotted wood is cut out and replaced with new, code-compliant plywood or OSB. We then integrate new underlayment and shingles to seamlessly match your existing roof, ensuring the repair is watertight and structurally sound. Our goal is to fix the problem completely, not just cover it up.
