The firm

We re-roof properly, in one go, with leadwork that outlives the warranty.

Ridgemark is a small, directly employed crew of slaters, tilers, leadworkers and scaffolders led by Tom and Maeve Brennan. We don't subcontract the high-risk work, we don't disappear when the punch list lands, and we don't bid what we can't honor. Every project gets one inspection, one fixed estimate, and a sealed envelope of removed-waste tonnage on closeout day.

  • A.

    One crew, no subcontractors

    The crew on the inspection is the crew on the scaffold. No temp labor, no new faces in week three.

  • B.

    Historic approved

    GAF Master Elite Roofer and on the city preservation review panel. Trusted on National Register and local landmark homes across metro Atlanta.

  • C.

Word of mouth

Half our work walks in through a friend.

Ridgemark stripped a hundred-year-old Vermont slate roof and put it back in seven weeks. Three other firms bid fourteen. We've already booked them for the chimney.
David & Cath M. Decatur · Historic district re-roof ★ ★ ★ ★ ★
We called Ridgemark for a leak. Tom came out the same day, fixed the valley, didn't charge until we had a full estimate for the rest. Five months later they did the whole roof.
Helen S. Marietta · Full re-roof ★ ★ ★ ★ ★
I've had three roofers in twenty years. These are the first who didn't try to sell me work the inspection didn't need. The lead detail on the dormer is photo-grade.

Frequently asked

Questions we field on every first call.

Q/01 How much does a full re-roof cost in metro Atlanta?

Most of our re-roofs land between $13,500 and $38,000. A 1,100 sq ft Vermont slate strip-and-relay on a two-story home sits around $19,000; a historic district barn conversion with chimney leadwork and reclaimed slate can be $45,000+. You'll get a fixed estimate at the inspection, not a vague band.

Q/02 Will you take on historic district properties?

Yes — it's a big chunk of our work. We're GAF Master Elite certified and have an in-house Certificate of Appropriateness specialist who works with the city preservation staff. We source like-for-like reclaimed slate, hand-make lead detailing, and document everything for the file.

Q/03 How long does a typical re-roof take?

A standard 3-bed home runs 3 to 5 weeks on site. Larger or heritage projects 6 to 12 weeks. Lead-time from booking to scaffold up is currently 6–10 weeks depending on season. We won't start the strip until the materials are in the yard.

Q/04 What's the difference between Vermont and Spanish slate?

Vermont slate (Poultney, Fair Haven) is denser, splits cleaner, and lasts 80–120 years on a Georgia roof. Spanish slate is roughly 60% of the price and lasts 40–60 years — great on a barn conversion, not the right choice on a historic district cottage. We'll show you samples of both in your driveway.

Q/05 Will you liaise with my insurer for storm damage?

Yes. We tarp-and-seal the same day, photograph the damage from drone and ground level, and submit a claims-adjuster pack within 48 hours. We deal directly with most major US home insurers — you don't have to chase.

Q/06 Is the 15-year guarantee insurance-backed?

Yes. Our workmanship guarantee is underwritten by an A-rated national insurer, so it survives even if we close up shop (we won't — the firm's 26 years old). The certificate transfers automatically to the next owner if you sell.
