What We Stand For

Four things we refuse to compromise on

Honest assessments

If your roof doesn't need replacing, we'll tell you. We've talked homeowners out of jobs they didn't need — that's how we earn the ones they do.

Family accountability

We're a family business, not a storm-chasing crew that disappears after the check clears. Our name is on every roof, and we live and work in the same communities we serve.

We meet your adjuster

From documenting the damage to meeting your adjuster on the roof, we guide you through the insurance process so most homeowners pay only their deductible.

Built to last

GAF factory-certified installation, manufacturer lifetime material warranties, and our own 2-year workmanship warranty on every job.

How We Work

From first call to final shingle

Free 24-hour inspection

We document every slope with photos and give you a straight answer — usually within a day of your call.

Claim & estimate

If there's storm damage, we document it and meet your adjuster. If not, you get a clear retail or financed estimate — no pressure.

One-day install

Most roofs are torn off and replaced in a single day. We protect your landscaping and leave the site cleaner than we found it.

Warranty & follow-up

You're covered by manufacturer and workmanship warranties — and we're a phone call away long after the job is done.

Licensed, Certified, Accountable

Credentials you can verify

Roofing is a trade where anyone can print a business card. We're licensed and bonded in three states, factory-certified by the largest shingle manufacturer in North America, and accountable to the BBB. Look us up — we'll wait.
