A replacement is mostly the things you will never see again
The shingles are the part you look at and the smallest part of whether the roof lasts. What decides that is the condition of the decking underneath, the underlayment, the flashing at every detail, the ventilation balance, and whether the old roof came off properly or got covered over. We do all of it the same way every time.
Tear-off, not layover. We take the old roof off to the bare deck. Shingling over an existing layer is permitted in some circumstances and it is cheaper, and we will not do it as a default, for three reasons: you cannot see or repair the decking under a layer you have not removed, the second layer traps heat and shortens the new shingles' life, and the uneven surface telegraphs through. It also makes the next replacement more expensive and more disruptive. On a Clarksville roof that is already fighting fifty-one inches of rain a year and a hot attic, giving up decking inspection to save a few hundred dollars is a poor trade.
What happens once it is bare. The deck gets walked and inspected. Sheathing that is soft, delaminated or rotten comes out and gets replaced with new, and that is priced per sheet rather than hidden in the total, because nobody can honestly tell you how many sheets you need before the shingles come off. Then: drip edge at eaves and rakes, ice and water membrane in the valleys and around every penetration, synthetic underlayment across the field, new step flashing and counter-flashing at every wall and chimney — new, not re-used, because re-using flashing is the single most common corner cut in this trade and it is where the roof will leak in six years. New pipe boots. New ridge vent where the ventilation calls for it.
Then the shingles. Architectural asphalt is what goes on the overwhelming majority of roofs in Montgomery County, and for good reason: it handles this climate, the range of products is wide, and the cost is manageable against a median home value around $263,600. Nailing pattern and nail count matter more than most homeowners realise — most manufacturer wind warranties are void if the nails are high, overdriven or too few, and that is invisible the moment the next course goes on. We nail to the manufacturer's spec in the nail zone, six per shingle where the wind rating calls for it, and that is not a line item you should have to ask about. Metal is the other real option here and we fit it where it earns its cost.
And the paperwork. Montgomery County Building Codes permits roof replacement, at $0.38 per square foot with a $25 minimum, and we pull it before the tear-off starts rather than after somebody notices. Tennessee requires a state contractor licence for projects of $25,000 and above through the Tennessee Board for Licensing Contractors; verify ours, and anybody else's, at verify.tn.gov. You get the permit number, the manufacturer's warranty registration and the workmanship warranty in writing, and the yard gets rolled with a magnet twice before we leave, because a roofing nail in a tyre a month later is a genuinely irritating way to remember a contractor.
What's included
Torn off to the deck
The old roof comes off so the sheathing can be seen and repaired. Layovers hide problems and cook the new shingles.
Decking priced per sheet
Rotten sheathing replaced and charged by the sheet, declared on the estimate, because the count is unknowable until it is bare.
All new flashing
Step and counter-flashing, valley metal, drip edge and pipe boots replaced new. Re-used flashing is where a roof leaks in year six.
Nailed to spec
Correct nail count in the nail zone at the right depth, which is what keeps the manufacturer's wind warranty valid.
Ventilation corrected
Intake and exhaust balanced while the roof is open, which is the only cheap moment to fix an attic that has been cooking shingles.
Permitted and cleaned
Montgomery County permit pulled before tear-off, and the yard magnet-rolled twice before the crew leaves.

These are 2026 ranges for Clarksville and Montgomery County, meant for budgeting rather than quoting. Pitch, the number of layers to come off, the condition of the decking and the flashing details all move the number. You get the scope and the price in writing after the inspection, and the inspection is free.

Questions we get about roof replacement
How long does a replacement take?
Most Clarksville houses are one to two days for a straightforward architectural shingle roof, weather permitting. Steeper pitches, multiple layers to remove, complex rooflines with several valleys and dormers, and significant decking repair push it to three. Metal takes longer. We give you a date range at the estimate and tell you honestly when rain is going to move it, because it will.
Can I just go over the old shingles?
It is sometimes permitted and we do not recommend it. You give up the ability to inspect and repair the decking, the trapped heat shortens the new shingles' life in a climate that already cooks them, the surface telegraphs through, and the next tear-off costs more. The saving is modest and the trade is bad. If you want it done that way, we will tell you the same thing in person and you can decide.
How much decking will need replacing?
Nobody can tell you before the shingles are off, and be sceptical of anyone who gives you a confident number up front. On a sound roof with no history of leaks it is often none or a sheet or two. Where there has been a long-running leak, or on an older roof, it can be a dozen. We price it per sheet on the estimate so you know the rate, show you what we find, and only replace what is genuinely bad.
Do you pull the permit?
Yes, on every replacement, before the tear-off. Montgomery County Building Codes handles it at $0.38 per square foot with a $25 minimum and you can reach them at 931-648-5718 if you want to confirm anything independently. The permit number goes on your paperwork. A contractor who suggests skipping the permit is telling you how they handle the rest of it too.
What warranty do I get?
Two separate things, and it is worth understanding the difference. The manufacturer warrants the shingles against defects for a period set by the product line, and that warranty depends on correct installation, which is why nailing and ventilation matter. Separately, we warrant our workmanship for a stated period in writing. Ask any contractor which is which and who honours the workmanship cover if they stop trading.
Will I have to move out?
No. It is loud, and it is dusty in the attic, so people working from home often plan around it and anyone with a nervous dog should. We protect landscaping and the areas below the eaves, keep the drive clear enough to use where we can, and clean up at the end of each day rather than only at the end of the job.
