Roof rot, especially from prolonged water exposure, is a silent destroyer. It can affect rafters, sheathing, and soffits, compromising your roof’s entire structure. For Cleveland homeowners, spotting and stopping rot early is essential.
Look for sagging areas, musty odors in the attic, or visible mold and discoloration on decking. These symptoms often point to prolonged leaks. Ice dams, clogged gutters, or improper attic ventilation are common triggers.
Repairs begin with removing all affected material. That includes peeling back shingles, cutting away rotted decking, and sometimes replacing rafters or fascia boards. 7/16″ OSB or ½” plywood are common replacements. Roofers may also upgrade underlayment to breathable or water-resistant materials, but often these are overkill.

Tip: Always replace "not patch" rotted wood
Dry rot is especially deceptive as it can spread with minimal moisture. Expect repairs to cost $600-$2,000 depending on square footage and structural damage. The labor is intensive, but skipping it risks future roof collapse.
Work with roofers who document the rot and share photos during the estimate process, this is best practice. That transparency builds trust and ensures you’re only paying for what’s necessary. Prevention? Regular attic checks and timely shingle replacement go a long way.
