Expert Reroofing and Roof Replacement Services in Castro Valley
Your roof protects your most valuable investment—your home. That’s why our reroofing services are designed to strengthen, upgrade, and future-proof your property.
Full Roof Replacement
We remove old, damaged roofing and replace it with modern, energy-efficient materials built to last decades. Whether you choose asphalt shingles, tile, or composite roofing, every installation is done to manufacturer specifications for full warranty coverage.
Reroofing (Overlay Installation)

Tear-Off & Eco-Friendly Disposal
We remove worn roofing and dispose of it responsibly. Our team takes care to protect your landscaping and property throughout the process.
Underlayment & Ventilation Upgrades
During reroofing, we upgrade your underlayment and ventilation systems to prevent moisture buildup, improve energy efficiency, and extend the lifespan of your new roof.
Structural Repairs & Reinforcement
From sagging decking to weakened rafters, we restore the integrity of your roof’s structure before installation begins—ensuring safety and long-term stability.
Every Wonderlin reroof includes a full inspection, premium materials, and expert craftsmanship that meets California building standards.
