Excel Roofing | Emergency Roofing Repair in Grand Rapids, MI

In Grand Rapids, roof deck rot is often caused by trapped moisture from ice dams in winter or compromised flashing. We fix it by first locating the source of the leak, safely removing the damaged decking, and replacing it with new, treated plywood. We then ensure proper underlayment and ventilation are installed to prevent future issues, protecting your home's structure.

We use a professional, low-pressure cleaning solution specifically formulated to kill the algae (Gloeocapsa magma) without damaging your shingles. To prevent regrowth, we can install zinc or copper strips along the roof ridge. When metal rains, it creates an environment that inhibits algae, providing a long-term solution to keep your Grand Rapids roof looking clean.

For durability against our freeze-thaw cycles and humidity, we recommend algae-resistant shingles with a solid warranty, proper synthetic underlayment for an added moisture barrier, and ensuring your attic ventilation meets Michigan code. Using these materials from the start builds a roof that's more resistant to the rot and stains we see locally, saving you money on repairs.
