Atmospheric River Season Test Your Roof? We'll Handle the Paperwork Too
San Jose's real roofing risk isn't hail — it's the wind-driven rain of winter atmospheric-river storms, which can overwhelm an aging roof or an undersized gutter system over a matter of weeks, not minutes. If a storm has damaged your roof, we'll document everything with dated photos, meet your insurance adjuster on-site if needed, and make sure the scope of work reflects the real damage — not just what's visible from the ground.
Roof Leaking Right Now?
A damaged roof doesn't wait for business hours. If you have active water intrusion during a storm or a sudden leak, call us directly — we prioritize emergency tarping and stabilization to stop the damage from spreading into your attic and walls.

Roofing FAQs
How much does a roof replacement cost in San Jose?
It depends on roof size, pitch, and material — a straightforward asphalt shingle replacement typically costs less than a tile or standing-seam metal system. We give you an exact, written number after a free on-site inspection, not a generic range over the phone.
Do I need a Title 24 cool roof?
California's 2025 Building Energy Efficiency Standards (effective January 1, 2026) require most re-roofing projects to use CRRC-rated cool-roof materials once a significant portion of the roof is replaced. We build compliant material options into every replacement quote so there are no permitting surprises.
How fast can you respond to an emergency?
For active leaks during a storm, we prioritize same-day tarping and stabilization whenever possible. Call (669) 316-8007 directly for the fastest response.
Do you offer free inspections?
Yes. Every inspection is free and comes with photos and a written summary of what we find — whether or not you move forward with repairs.
