Buying a home? Insurance claim? Second opinion? Get a complete video walkthrough of your roof’s true condition.
Not all roofers
are the same.
Anyone with a truck and a ladder can call themselves a roofer. Licensed, insured, and reviewed is a different story. Here’s what sets us apart.
Rated by your neighbors
Over 1,200 verified five-star Google reviews from local homeowners. Not a paid platform — actual customers, actual ratings.
Fully licensed & insured
California State License Board verified. Full general liability and workers’ compensation. Verifiable on the CSLB website at any time.
Every install recorded
We record every roof from prep to cleanup. You see the underlayment, the flashings, the work no other roofer wants you to see.
Local crews, never subcontractors
Every job is done by our W-2 employees — never subcontracted out. Same team, same standards, every project, every time.
Simple. Honest.
No pressure.
We know how roofing companies usually work. The high-pressure pitch, the “today-only discount,” the contract on a clipboard. That’s not us. Here’s how we do it instead.
Call & describe your project
A senior estimator answers — usually under 30 seconds — and asks the right questions to understand your roof.
We come out and inspect
We climb your roof, document it on video, and write up a real quote with real materials and a real timeline.
You decide. No pressure.
Take a week. Get other quotes. Show your neighbor. If you don’t like ours, you owe us nothing — not even a follow-up call.
