Tear off, not layover
The old covering comes off so the decking can actually be seen. Rot, delamination and previous bodged repairs only show up once the roof is stripped, and covering them costs you the next roof early.

Install day
What Happens During a Roof Replacement?
Tear off comes first, then the deck is inspected and any rot cut out and replaced, then underlayment goes down the same day so the house is never left open overnight. New flashing, pipe boots and ventilation details are fitted with the shingles, and the job ends with debris removal and a magnet sweep. One to three days is normal for a Cumming home.
Decking repairs priced honestly
Sheets that are soft or rotten are replaced. We show you the boards and agree the count before they are billed, so decking never becomes an invisible line on the invoice.
All new flashing and boots
Wall and chimney flashing, valleys and pipe boots are renewed rather than reused. Reused flashing is the single most common reason a new-looking roof leaks within a couple of years.
Ventilation corrected while open
Intake and exhaust are balanced and the ridge vent cut properly. Georgia attic heat is what ages shingles from below, so this is the cheapest years you will ever add to a roof.
Timing the decision
When Is It Time to Replace Rather Than Repair?
Replace when the failures are no longer in one place: leaks appearing on different slopes, granule loss across the whole roof, widespread curling or cupping, or an asphalt shingle roof past about 20 years. A single failed detail on an otherwise sound roof is a repair, and we will tell you when that is the honest answer.
Selling within a couple of years changes the maths too. A roof at the end of its life will come up in the buyer inspection either way, so replacing it deliberately beats negotiating over it under time pressure.
If you are still weighing one bad leak against the whole roof, the estimator that prices tear off by roof size and pitch puts a number against both paths before you commit.

Replacement questions
What Should You Ask Before Approving a Roof Replacement?
Cost, timing, permits, layovers, what the scope actually includes and how long the new roof should last. Straight answers to all six are below.
How much does a full roof replacement cost in Cumming, GA?
About $30,536 for the average Cumming roof, which local measurement data puts at 5,500 square feet with pitch included, at roughly $5.55 per square foot for asphalt shingle (Instant Roofer, August 2026). A smaller 2,000 square foot home is reported at $7,000 to $17,000, or $3.50 to $8.50 per square foot (RoofHero, 2026). Those are published market figures for the Cumming area, not a quote from us.
How long does a roof replacement take on a Cumming home?
Usually one to three days for a standard asphalt shingle roof. Day one is tear off, dry-in and often the bulk of the new shingles. Complex roofs with multiple valleys, dormers, skylights or a steep pitch take longer, and finding rotted decking during tear off adds time because the deck has to be replaced before the roof can be closed in.
Do I need a permit to replace my roof in Forsyth County?
No. Forsyth County lists roofing, re-roof and shingle replacement as work that does not require a building permit in its Do I Need a Permit guidance. If the job extends into structural framing repairs, confirm that portion with the county before work starts.
Can you install a new roof over the old shingles?
It is sometimes physically possible but we do not recommend it. A layover hides the decking, so nobody sees the rot or the failed flashing underneath, it traps heat that shortens shingle life, and it makes the next replacement more expensive because two layers have to come off. Tear off also lets us inspect and correct the ventilation while the roof is open.
What is included in a roof replacement scope?
Tear off of the existing roof covering, inspection and replacement of any damaged decking, new underlayment, new flashing at walls, chimneys, valleys and penetrations, new pipe boots, ridge and ventilation details, the shingles themselves, then debris removal and a magnet sweep of the property. Anything excluded should be named in writing before you sign.
How long should a new asphalt shingle roof last in Georgia?
Typically 20 to 25 years for architectural asphalt shingle in this climate, though heat and humidity in North Georgia are hard on roofs and attic ventilation makes a real difference to which end of that range you land on. Poor ventilation cooks shingles from underneath and can take years off the roof regardless of the shingle warranty.
