Knoxville Roofing Contractors

That depends on the size of the roof, its pitch, the material, and what the decking looks like once the old covering is off. We price by the roofing square against your measured roof rather than publishing one figure meant to fit every house, and the written estimate itemizes tear-off, underlayment, shingle, flashing, ventilation and a decking allowance as separate lines.

The number moves once we see the decking. Rotted plywood found during tear-off is the most common surprise, and it can add $500 to $5,000.

If damage is limited to a small area or a few shingles, repair is usually the right call. If the roof is over 20 years old, has multiple leaks, soft decking, or has been patched repeatedly, replacement is more cost-effective long-term.

We give an honest recommendation based on what the inspection shows.

Not automatically. A 20-year asphalt roof is near the end of its life, but near the end is not failed. What matters is what an inspection finds: curling shingles, granule loss down to the mat, soft decking, or repairs that keep leading to the next leak.

If the flashing is sound and the shingles are healthy, you may have years left. If you are patching every season, replacement is already cheaper.

Asphalt shingle service life varies by product, installation, attic ventilation, maintenance, and weather exposure. Industry guidance commonly treats about 20 years as a general roof-service benchmark, not a guaranteed shingle lifespan. Metal generally outlasts asphalt, but by how much depends on the system and on the detailing rather than on a number anyone can quote up front. Flat membrane service life depends on the membrane, the slope and the detailing at the edges and penetrations. Poor installation cuts it short on any of them.

Rarely. That number is the warranty tier, not a lifespan promise, and it assumes ideal conditions. Asphalt shingle service life varies by product, installation, attic ventilation, maintenance, and weather exposure. Industry guidance commonly treats about 20 years as a general roof-service benchmark, not a guaranteed shingle lifespan.

The biggest factor is attic ventilation. Poor airflow cooks the shingles from underneath and can cut a third off the life of the roof, which is why we inspect ventilation on every replacement instead of only the surface.

Shingles, up front, by a wide margin. Asphalt is priced per roofing square as well, by product and by pitch, and we give you that figure against your measured roof. Metal starts at $1,062 per roofing square for exposed-fastener systems and $1,525.50 per roofing square for standing seam, with one roofing square covering 100 square feet of roof area.

Metal generally outlasts asphalt, but by how much depends on the system and on the detailing rather than on a number anyone can quote up front. Asphalt shingle service life varies by product, installation, ventilation, maintenance, and weather exposure, and metal systems are rated for considerably longer, so metal wins over decades — but only if you plan to stay. If you are selling in five years, shingles are the better financial decision.

Bad installation, not the metal. Cost is the obvious barrier, but the failures we get called to fix are seam errors and fastener problems. Exposed-screw systems use rubber washers that dry out and crack around year 12 to 15.

Standing seam avoids that but costs more. Metal also needs installers who actually know metal, and the mistakes do not show until it rains.

Labor, usually — tear-off, disposal, and skilled installation run neck and neck with the materials. But the line that surprises homeowners is decking.

Rotted plywood underneath is invisible until the old roof comes off, and it can add $500 to over $5,000. We handle it with a written Change Order and photographs, never as a silent add-on at the end.

Winter, usually. Demand drops after storm season and scheduling opens up. We work year-round in East Tennessee, and a January roof is the same roof as a June roof as long as the weather that week cooperates.

Roofing prices are expected to rise 4 to 6 percent through 2026 on labor and material costs, so waiting for a better price is unlikely to pay off.

Four signs. They want 50% or more before materials arrive. The estimate is one number with no breakdown of flashing, disposal, or decking. They knocked on your door after a storm and want you to sign today. Or they claim damage but cannot show you photos of it.

We ask 33% at signing, itemize the quote, and document every finding with photographs before we touch anything.

Yes. On-site roof inspections are free for standard cases across Knoxville and Surrounding East Tennessee.

For complex inspections requiring drone work, attic access, and moisture mapping, we offer a $350 Technical Assessment that is credited back if you move forward with the project.

If we find rotted decking, framing issues, or moisture damage once the old roof is off, we stop and document it with photos. We explain the scope and provide a written Change Order before continuing.

New shingles go on after the damage underneath has been documented and addressed in writing.

Yes. We document hail and wind damage clearly and provide accurate material takeoffs. We work alongside your insurance adjuster.

We do not promise approval — that is the carrier's decision — but we make sure the scope is honest and well documented.

Yes. For active leaks, exposed decking after a storm, or tree damage, we respond fast to tarp and dry-in the roof. This prevents interior damage before the permanent repair.
