What things should you know when replacing a roof?
Short answer. Before replacing a roof, know exactly what the estimate includes (tear off, underlayment, flashing, ventilation, decking allowance), whether a permit and HOA approval are needed, which warranties apply, and what replacement day will look like. Those details matter more than the shingle brand.
Scope details that change the result
- Full tear off rather than roofing over old shingles; see roofing over existing shingles.
- Decking: the per sheet price for rotten wood found after tear off.
- Underlayment and ice and water barrier in valleys and around penetrations.
- New metal: drip edge, pipe boots, step and chimney flashing, not reused rusty pieces.
- Ventilation balanced between soffit intake and ridge exhaust.
Paperwork
- Permits vary by Georgia city and county. Ask who pulls it.
- Many HOAs require color or product approval before work starts; see HOA roof approval in Georgia.
- Get a written contract, a materials list and both warranties: manufacturer and workmanship.
- If insurance is paying, read your contract's cancellation terms. Georgia lets you cancel an insurance dependent roofing contract if the claim is denied.
On the day
Expect noise, a dumpster or trailer in the driveway, magnet sweeps for stray nails and, on an average size roof, most of the work done in one day. Move cars, take down wall hangings on the top floor, and keep kids and pets clear. Roof replacement day walks through it hour by hour.
Afterward
Keep your contract, invoices, warranty registration and photos together. They matter for future claims and for selling the house.
