Roof Edge Rot Repair, Modesto, CA

As a California Licensed General Contractor (CSLB #1130391), we are authorized to perform structural rot repair. This means we can legally sister joists, rebuild rafter tails, and replace load-bearing framing members compromised by decay at the roof edge.

We address the root cause of the decay by identifying and correcting the moisture source. Whether it is failed flashing or poor drainage, we ensure the underlying issue is resolved so the wood decay does not immediately return.

Our crew uses moisture meters for accurate diagnosis of the decayed wood along the roof perimeter. This allows us to precisely map the extent of the damage, differentiating between cosmetic surface rot and deeper structural decay requiring replacement.

We rebuild the compromised roof edge using rot-resistant and treated lumber for lasting results. This structural material, combined with proper flashing and a Bituthene Waterproof Membrane, ensures the repaired perimeter is protected from future water intrusion and decay.

When a roof edge repair exceeds our scope, such as requiring a full roof replacement, we coordinate directly with our sister divisions. This ensures all aspects of the project are handled correctly without attempting work outside our specific lane.

Replacing decayed roof edge decking and rafter tails restores the load-bearing capacity of the perimeter. This structural reinforcement ensures the roof can safely support the weight of the roofing materials and withstand environmental stresses without sagging or failing.

Correcting the moisture source and installing proper flashing at the roof edge prevents water from entering the building envelope. This protects the interior walls, insulation, and underlying framing from significant water damage and the subsequent development of mold.

Removing the decayed wood and treating the surrounding area stops the progression of dry rot. This prevents the fungus from spreading to adjacent structural members, containing the damage and reducing the scope of future necessary framing repairs.

A solid roof edge provides a secure substrate for the installation of drip edges and roofing materials. This ensures the perimeter is properly sealed against wind-driven rain and ice damming, maintaining the overall weather resistance of the roof system.

Integrating a Bituthene Waterproof Membrane during the rebuild provides a durable barrier against moisture. This long-term moisture management strategy ensures the repaired roof edge remains dry, significantly extending the lifespan of the structural framing and exterior trim.

While some roofers handle minor decking issues, extensive structural dry rot requires a licensed general contractor. We specialize in removing decayed rafter tails, sistering joists, and rebuilding the roof edge with treated lumber before the roofing material is installed.

Yes, structural decay at the roof edge compromises the load-bearing capacity of the eave and allows continuous water intrusion. Prompt repair is necessary to prevent the rot from spreading to interior framing and causing significant, extensive water damage.

The cost depends on whether the decay is cosmetic surface rot or structural damage requiring rafter reinforcement. We provide a detailed, written estimate after a site inspection to accurately assess the extent of the decay and required moisture correction.

If the underlying decking and fascia are sound, the drip edge can be replaced. However, if dry rot is present, the decayed wood must be removed and rebuilt with rot-resistant material before installing new flashing and a drip edge.

Repair involves removing the decayed fascia, soffit, and rafter tails. We then sister new treated lumber to the structural framing, install a Bituthene Waterproof Membrane, and rebuild the exterior trim, ensuring the moisture source is permanently corrected.
