Shingle Roof Replacement in Kennesaw, GA
Shingle roof replacement means removing the existing asphalt shingles down to the roof deck, inspecting and repairing the decking, installing fresh underlayment, flashing and drip edge, then fastening a new layer of asphalt shingles to manufacturer specifications.
What Gets Replaced During a Full Shingle Roof Replacement
A full replacement is more than a new layer of shingles. When we tear off a roof in Kennesaw, here is what the crew handles from start to finish:
- Tear-off and disposal. We strip the old shingles, felt and nails, load them into a dumpster staged at your driveway, and haul the debris away when the job is done.
- Deck inspection and repair. Every board visible after tear-off gets checked. Soft or water-damaged decking is replaced before anything new goes down, because shingles nailed to rotten wood will not hold.
- Underlayment and ice/water barrier. A synthetic underlayment covers the whole deck, with self-adhering waterproof membrane in valleys, around chimneys, and along eaves where wind-driven rain pushes in during Georgia storms.
- New flashing and drip edge. Step flashing at walls, boot flashing at plumbing vents, and metal drip edge at every eave and rake. Reusing old flashing is how leaks start.
- Shingle installation. Asphalt shingles installed with proper nail placement, a starter course at the eaves, and hip and ridge caps along every peak.
- Ventilation check. Ridge vents and soffit intake are verified so the attic moves air the way the shingle manufacturer requires. Poor ventilation shortens shingle life and can affect warranty coverage.
Signs Your Kennesaw Home Needs a Roof Replacement Rather Than a Repair
Cobb County roofs take a beating from hail, summer heat and straight-line thunderstorm winds. Weather watches and warnings from the National Weather Service matter for storm prep, but the roof itself tells you when replacement time has arrived. Look for:
- Curling, cupping or cracked shingle tabs visible from the ground
- Granules collecting in gutters and at downspout discharge points
- A previous repair layer — if shingles have been laid over shingles, a full tear-off is usually the right call next
- Daylight visible in the attic or active leaks after rain
- Sagging roof lines between rafters, which points to decking or structural trouble
- Shingle patches that have failed more than once in the same area
Any one of these means an inspection is worth scheduling. Our technicians climb the roof, photograph what we find, and give you a straight answer about repair versus replacement. No pressure, no scare tactics — if the roof has five good years left, we will tell you that.
Shingle Options We Install
Most Kennesaw homes use asphalt shingles because the material suits Georgia's climate and the cost fits most budgets. Our team members install standard three-tab shingles and architectural (dimensional) shingles, and we explain the practical differences before you choose:
| Option | What It Is | Typical Use |
|---|---|---|
| Three-tab asphalt | Single-layer shingle with a flat profile | Budget-minded replacements, rental and secondary properties |
| Architectural asphalt | Thicker, multi-layer shingle with dimensional shadow lines | Most single-family homes in Cobb County; handles wind uplift better than three-tab |
| Impact-resistant asphalt | Shingle rated to resist hail impact | Homes with prior hail damage or owners wanting added durability |
Comparison: Repair, Overlay, or Full Replacement
Homeowners often ask whether they can save money with a repair or an overlay. Here is how the three approaches compare, and when each one makes sense:
| Approach | What Happens | strong Fit | Trade-off |
|---|---|---|---|
| Section repair | Damaged shingles or a small area is removed and replaced | Isolated wind or hail damage on an otherwise sound roof | Matching older shingle color is difficult; leaks can continue elsewhere |
| Overlay (shingle over shingle) | New shingles fastened directly over the existing layer | Rarely recommended; deck problems stay hidden underneath | Traps heat and moisture, adds weight, and most manufacturers limit or void warranty terms |
| Full tear-off replacement | Everything comes off, deck is inspected and repaired, new system installed | Aging roofs, multiple leak points, storm damage, or a planned long-term hold on the home | Higher upfront cost, but the deck and flashing are new and warrantied as a system |
Our recommendation on most Kennesaw roofs is a full tear-off. The decking inspection alone justifies it — you does not see soft wood or old nail holes through an overlay. If you plan to stay in the home, the full replacement is the option that stops the leak cycle. Preparing a home for major work, including contractor selection and written agreements, is covered by general guidance from the SBA's business resources on vetting contractors — the same advice applies to hiring a residential roofer: verify the license, get the scope in writing, and avoid anyone demanding full payment upfront.
How the Kennesaw Pro Roofing Process Works
Roofing has a reputation for high-pressure sales, and we built our process specifically to avoid that. Here is what working with us looks like:
- Inspection. We inspect the roof, attic and flashing, then walk you through photos of what we found.
- Written quote. You receive an itemized estimate covering tear-off, materials, decking allowance, and cleanup. The price we quote is the price on the invoice unless the scope changes.
- Material selection. We bring shingle samples and explain color and ventilation options in plain terms.
- Scheduling and installation. Most residential replacements are completed in one to three working days, weather permitting. Our technicians tarp the property, protect landscaping, and roll the yard with a magnet for nails at cleanup.
- Final walk-through. You inspect the finished roof with us before we call the job complete.
Our license number is ROC-1145321. Our crews are a local Cobb County crew, which means the person who inspects your roof is the person who manages the installation.

FAQ
How long does a shingle roof replacement take in Kennesaw?
Most single-family homes in the Kennesaw area are completed in one to three working days, depending on roof size, pitch and how much decking needs repair. Weather is the main variable — we schedule around rain and will not leave your roof open overnight without protection.
Can you replace a shingle roof in winter?
Yes. Asphalt shingle installation happens year-round in north Georgia, though cold weather affects sealant activation, so we follow manufacturer temperature guidelines for when each product should be installed. Scheduling in the off-season is often easier.
Will my homeowner's insurance pay for a roof replacement?
Insurance typically covers replacement when the damage comes from a covered event such as hail or wind, and it usually does not cover normal wear and age. Our crews document storm damage with photos and provide the paperwork your adjuster needs. Coverage decisions rest with your carrier and policy terms.
Do I need to replace my gutters at the same time?
Not usually. Gutters are removed and reinstalled as part of the drip-edge work, and we inspect them for attachment and slope during the job. If the gutters are sound, they stay. If they are pulling away or rusted through, we will show you before recommending anything beyond the roof itself.
What warranty comes with a new shingle roof?
Shingle manufacturers provide material warranties on their products, and the length depends on the shingle line you choose. Our workmanship warranty covers the installation itself. Both are spelled out in writing before work begins, and we register the manufacturer warranty for you at completion.
