Some roofs are simple. This was not one of them.
For a home near Monarch Court in Cumming, GA, Supreme Roofing and Reconstruction completed a full roof replacement after documented storm damage. The roof measured 4,639 sq. ft., had 21 roof facets, and a predominant pitch of 12/12. In homeowner terms: big, steep, and complex.
That was the final invoice amount — a $32,468.58 base replacement plus a $4,459.72 supplement for items the first insurance estimate didn't fully account for. This was a covered insurance claim for hail and wind damage.
What the storm damage inspection found
The inspection was completed by Jacob Hamby with Supreme Roofing and Reconstruction. Storm data showed 1-inch hail, 45 mph winds, and a south-driven storm direction — the kind of event that leaves marks on every slope.
The inspection documented:
- Bruised shingles across all roof slopes
- Impact craters and fractures in the shingle mat
- Significant granule loss from hail impacts
- Dented HVAC roof vents
- Dented downspouts
- Dented box vents
- Existing wear — severe granule loss and cracking on hip and ridge shingles (roof was approximately 12 years old)
The documented storm damage was sufficient to support a full roof replacement claim. The inspection report distinguished between storm-related damage and normal wear, which is critical in the insurance process.

The final cost breakdown
| Original roof replacement estimate | $32,468.58 |
| Supplement total | $4,459.72 |
| Final invoice amount | $36,928.30 |
The supplement added ice and water barrier, gable cornice return and strip work, and detach/reset of high-grade gutter guards — items that were either pre-existing on the home or required for proper installation but weren't fully captured in the initial insurance scope.
What the roof size actually means for cost
The EagleView report measured 4,639 sq. ft. — approximately 46.4 roofing squares. Here is the full measurement breakdown:
| Total roof area | 4,639 sq. ft. |
| Roofing squares | ~46.4 squares |
| Total roof facets | 21 |
| Predominant pitch | 12/12 |
| Ridges and hips | 268 ft. |
| Valleys | 168 ft. |
| Rakes | 138 ft. |
| Eaves | 236 ft. |
| Cost per sq. ft. | ~$7.96 |
| Cost per roofing square | ~$796 |
168 feet of valleys and 21 roof facets on a 12/12 pitch is not the same job as a simple two-slope ranch roof. Each valley, hip, ridge transition, and facet adds complexity — and with a 12/12 pitch, every one of those details is being worked at a steep angle.
The installation in progress
Why the steep pitch changes the price
A 12/12 pitch means the roof rises 12 inches for every 12 inches of horizontal run. That is a 45-degree slope. The estimate included separate steep roof charges for 7/12–9/12 sections and 10/12–12/12 sections.
On a steep roof, everything takes longer and requires more care:
- Material staging is harder — bundles have to be lifted and placed differently
- Tear-off is more difficult — old shingles and underlayment have to be managed on a slope
- Safety setup adds time — harnesses, anchor points, and rope systems are required
- Installation pace slows — crews work more deliberately on steep surfaces
A 4,639 sq. ft. roof at 12/12 is a different animal than the same square footage on a walkable 4/12 slope. The labor hours are higher, the safety overhead is real, and the pace of the job reflects that.
What was installed
The roof was replaced with TAMKO Titan XT shingles in Rustic Black. The material order for this project included:
- 165 bundles of TAMKO Titan XT shingles — Rustic Black
- 4 rolls of TAMKO synthetic underlayment
- 5 bundles of TAMKO starter strip shingles
- 11 bundles of TAMKO hip and ridge shingles — Rustic Black
- 14 pieces of ridge vent
- 24 pieces of black aluminum drip edge
- Pipe boot material
- Coil roofing nails
- Black spray paint for roof accessories
That is a serious material order. 165 bundles of shingles, 4 rolls of underlayment, and all the accessory products required to complete a properly installed roofing system — not just shingles nailed to decking, but a full layered system designed to protect the home.
Why valleys and flashing matter on a roof like this
This roof had 168 feet of valleys. Valleys are where two slopes meet and water concentrates. On a large, complex roof with 21 facets, valleys are everywhere — and each one has to be installed correctly because that is exactly where leaks start when they are not.
The scope also included chimney flashing and step flashing at wall-to-roof transitions. Those details matter because water finds transitions. A shingle field can be installed perfectly, but if the flashing at a chimney, dormer, or wall is compromised, the roof is not watertight.
On a roof this complex, getting the shingles right is only part of the job.
The warranty
This roof was registered with the TAMKO DiamondShield Enhanced Limited Warranty. The warranty covered the TAMKO Titan XT shingles in Rustic Black across 46 squares and included TAMKO accessory products — hip and ridge shingles, starter strip, synthetic underlayment across the field, and moisture guard in valleys and at penetrations.
A warranty like this covers more than the shingles. It covers the full system — which is why using matching accessory products from the same manufacturer matters. A warranty that only covers the shingles but not the underlayment or accessories is a narrower protection than most homeowners realize.
The completed roof
What Cumming homeowners should take from this
This project is a real example for homeowners in Cumming and Forsyth County with larger, steeper homes. A 4,639 sq. ft. roof at 12/12 is not an average replacement job — and the price reflects that. But the cost is also not arbitrary. It breaks down to $7.96 per square foot, which accounts for the size, the complexity, the materials, the labor required for steep work, and a full warranty-backed system.
If you have a home in Cumming with a steep or complex roofline — especially after a hail or wind event — the first step is an honest inspection. Storm damage is not always visible from the ground, and the inspection documentation is what drives the insurance process.
