Roof decking (also called sheathing) is the foundation of your entire roofing system. It’s the structural layer of plywood or OSB that sits beneath your underlayment and shingles. When decking is damaged, the entire roof is compromised — and it must be repaired before any new roofing is installed.
What Damages Roof Decking on Longmont Homes?
- Long-term moisture intrusion from undetected leaks
- Poor ventilation causing condensation buildup
- Ice dam water backing under shingles over multiple winters
- Severe hail impact on older or thinner decking
- Age and natural deterioration in older Colorado homes
How We Assess and Repair Decking
During every roof tear-off in Longmont, we walk the entire deck looking for soft spots, delamination, mold, and rot. Damaged sections are replaced with new OSB or plywood before new roofing is installed. We document all decking repairs for your records and insurance.
Don’t Skip Decking Inspection
Some contractors try to save time by skipping thorough decking inspections. At Josh Brooks Construction and Renovation Inc., decking inspection is non-negotiable. Installing new shingles over bad decking means your new roof will fail prematurely.
