Shingle roofing in Hendersonville & Gallatin.
The roof most houses here already have, and the one almost every hail claim in Middle Tennessee is written against. What decides whether a shingle roof reaches its service life is rarely the shingle: it is the deck underneath, the nailing pattern, and whether the valleys and eaves were detailed or merely covered.
Sumner County along Old Hickory Lake. Lakeside exposure means wind is the load that matters, and much of the housing stock dates to the 1970s and 80s — a generation of roofs arriving at replacement age at roughly the same time.

Questions
- Architectural or three-tab — what is the difference?
- A three-tab is a single flat layer with a repeating cut-out. An architectural shingle is laminated from two, which is where the depth, the shadow line and the extra weight come from. Nearly everything installed on a Tennessee house today is architectural, and three-tab shows up mostly on outbuildings and on repairs matching an older roof.
- Can you lay the new shingles over the old ones?
- Sometimes it is permitted, and it is almost never the right call. A recover hides the decking — and if the decking is what failed, you have paid to install a new roof on top of the problem. It also traps heat against the new layer, which shortens it.
- Does the attic really change how long the roof lasts?
- Yes, and it is the part nobody looks at. Intake at the soffit and exhaust at the ridge have to be balanced; an attic that cannot breathe cooks the shingle from underneath and the failure gets blamed on the material. We check it before we quote the roof, not after.
