Roof Replacement & Repair in Martinez, GA

Tear-Off, Not Overlay

Columbia County code permits a single overlay, but I won't quote one. Two layers add 200–300 lbs per square, hide deck rot, void most manufacturer warranties, and shorten the second roof's life by 20%. We always tear down to the deck, sister or replace any soft sheathing, then start clean.

Balanced Ventilation Math

FHA's 1/300 rule sets the baseline: 1 sq ft of net free vent area per 300 sq ft of attic floor, split evenly between intake and exhaust. On a typical 2,400 sq ft Martinez ranch with a hipped roof, that means around 8 linear feet of ridge vent paired with continuous 2-inch soffit slots — not the 6-inch round vents builders threw in for cost.

Synthetic Underlayment & Ice-and-Water Detail

We don't use 15# felt. Period. Synthetic underlayment (GAF FeltBuster, Owens Corning Deck Defense) lays flatter, walks safer, and won't tear when wind catches it during a tear-off. At eaves, valleys, and around every pipe boot, chimney, and skylight, we add 3 ft of self-adhered ice-and-water membrane.

What's different about roofing a Martinez home

Most of Martinez was built in the same 15-year window with similar materials and the same shortcuts. Once you know what they cut, you know what to fix at re-roof.

• Builder-grade pipe boots — Original neoprene collars are split by year 12. We replace every one with lead or all-metal Perma-Boots that outlast the new shingles.
• Round can vents instead of ridge vent — Static box vents move a fraction of the air a continuous ridge vent does. We cut a proper ridge slot and remove the old cans during tear-off.
• Shingle-over valleys — Woven valleys clog with pine straw from the wooded lots near Riverwood. We switch to open metal valleys with a W-profile so debris washes through.
• HOA color approvals — West Lake, Jones Creek, and several Furys Ferry HOAs require shingle color sign-off. We submit the sample board on your behalf before order.

What moves the price on a Martinez roof replacement

Pricing for a typical Martinez ranch (28–35 squares, 5/12–7/12 pitch) is more predictable than Augusta's older stock — but a few line items still swing the number.

• Sheet count for deck repair — Most tear-offs uncover 1–3 bad sheets, usually around bath vents or a previously leaking chimney. We charge a flat per-sheet rate, listed in the contract.
• Ventilation rebuild — Removing static cans, cutting a continuous ridge slot, and opening soffit intake adds linear footage to the bill but is the single highest-ROI upgrade we sell.
• Skylight age — Velux and Wasco units over 15 years old should be swapped while the surrounding field is open. Doing it later cuts into a fresh shingle field and creates a warranty seam.
• Gutter coordination — If gutters are getting replaced too, we sequence drip edge install with the gutter crew so the apron tucks behind correctly. Done out of order, water gets behind the fascia.
• Color and brand — GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark all price slightly differently. Designer profiles (Camelot, Grand Manor) carry a meaningful uplift.

Final number is fixed before tear-off, and the only line item that can move is documented deck-sheet count — measured and photographed in front of you.

How a Martinez tear-off and replacement actually runs

Most Martinez jobs are two working days. Day one we tear off the existing shingles and underlayment, inspect the deck, replace any soft sheathing, dry the roof in with synthetic underlayment, and run ice-and-water at eaves, valleys, and penetrations. The roof is fully weather-tight by end of day even if shingles aren't on yet.

Day two is shingles, flashing details, ridge vent, and ridge cap. By mid-afternoon the crew is sweeping the property, magnet-picking the lawn for nails, and loading the dumpster. Final walk happens with you that evening or first thing the next morning — whichever fits your schedule.

Columbia County inspection is scheduled at completion. The inspector signs off the permit, we send you the green tag and the manufacturer warranty registration, and the file closes. Total elapsed time from contract signing to closed permit on a standard Martinez home is usually under three weeks.

Pipe boots are the single most common leak source on a 12–15 year old Martinez roof. The neoprene collar dries out, cracks at the base of the vent stack, and water tracks down the pipe into the bath fan housing. We replace every boot at re-roof — no exceptions — and switch to lead flashings or all-metal Perma-Boots that outlast the shingles.

If your home backs up to wooded lots near Riverwood Plantation or Bartram Trail, expect granule loss from constant pine-needle abrasion and acidic tannin runoff. We recommend brush-back from overhanging branches before tear-off and, when feasible, a metal valley liner instead of woven shingle valleys — far easier to clear debris from each fall.
