What do roofers do when replacing a roof? Homeowners in Vancouver, WA often ask this question when preparing for a full roof replacement. Understanding each step of the process helps you know what to expect and ensures your home stays protected throughout the project.


When replacing a roof, roofers begin by removing the old shingles and any existing roofing materials down to the decking. This allows them to inspect the roof structure for damage, rot, or soft spots. Any compromised decking is repaired or replaced before new materials are installed.


Removing the Old Roofing Materials

The first major step is tearing off the old shingles, underlayment, and flashing. This exposes the roof deck and ensures the new roofing system is installed on a clean, solid surface. Skipping this step can trap moisture and shorten the life of the new roof.


Inspecting and Repairing the Decking

Once the old materials are removed, roofers inspect the wood decking underneath. In Vancouver, WA, consistent rain and moisture can lead to hidden wood rot. Damaged sections are replaced to create a stable foundation for the new roofing system.


Installing Underlayment and Moisture Barriers

After repairs are completed, roofers install new underlayment. This protective layer acts as a moisture barrier between the shingles and the decking. In the Pacific Northwest climate, high quality underlayment is critical for long term protection against rain and damp conditions.


Installing New Shingles and Flashing

Next, the new shingles or roofing material are installed according to manufacturer specifications. Flashing is placed around chimneys, vents, valleys, and other roof penetrations to prevent water intrusion. Ridge caps are installed along the roof peak to seal and protect the highest points.


Ensuring Proper Ventilation

Proper ventilation components are installed or updated during the replacement process. Balanced intake and exhaust ventilation help regulate attic temperature and moisture levels, which extends the life of the roofing system.


Final Inspection and Cleanup

After installation, roofers perform a final inspection to confirm the roof meets manufacturer guidelines and local building codes. The job site is cleaned thoroughly, and debris is removed to leave your property in good condition.
