A Small Company with a Big Reputation
From a single leak to a full tear-off and replacement. Owner-operated means Duane is on every job, every time. No crews you've never met.
Leaks, missing shingles, storm damage. We find the problem and fix it fast — most repairs done same-day so you're not left waiting.
When repairs won't cut it, we handle the full tear-off and replacement. New underlayment, flashing, ventilation — everything by the book.
Buying, selling, or just want to know where things stand. Honest assessment, written report, no pressure to buy anything you don't need.
Concrete tile, clay tile, asphalt shingles — we work with all of them. Material expertise that comes from doing this every single day.
TPO, modified bitumen, built-up roofing. Flat and low-slope systems for commercial properties, warehouses, and multi-unit buildings.
Middle of the night, middle of a storm — doesn't matter. When water's coming in, we answer the phone. Rapid response for active leaks.
You're not getting a sales rep and a crew you've never met. You're getting Duane — the owner — on your roof, at your door, answering your calls.

No hidden fees, no surprise line items. You get a detailed estimate before any work starts, and that number is the number you pay.
