- Check eligibility for the federal Energy Efficient Home Improvement Credit (up to $1,200/year) or the 30% Residential Clean Energy Credit.
- Avoid the cheapest quote — in our network it's a strong predictor of change-orders later.
When NOT to skimp
Some line items are tempting to cut and almost always cost more later: full tear-off vs. overlay on roofs, Manual J load calcs on HVAC, full-frame vs. insert on rotting window openings, and waterproofing/membrane work in bath remodels. If a contractor offers to skip any of these to "save money," get a second opinion.

Frequently Asked Questions
How much does a new roof cost in Nashville?
A typical 2,000 sq ft Nashville home with architectural asphalt shingles runs $9,200 to $18,400 installed in 2026, depending on pitch, tear-off layers, and decking condition. Metal roofs run roughly 60–90% higher.
How long does a roof replacement take?
Most Nashville asphalt-shingle replacements complete in 1–2 days. Metal and tile typically take 3–5 days. Weather can extend the timeline.
Do I need a permit to replace my roof in Nashville?
Yes — Metro Nashville requires a building permit for re-roofs. Your licensed roofer should pull this on your behalf. Williamson, Rutherford, and Wilson counties have similar requirements.
How long does a roof last in Tennessee?
Architectural asphalt shingles last 22–30 years in Middle TN. Metal roofs last 40–70 years. Heavy tree cover, hail, and poor attic ventilation shorten lifespan.
