Got roofing questions? We’re answering the four most common ones to help you make informed decisions about your roof.

A new roof is one of the biggest investments most homeowners ever make on their home. The decision deserves real research, not just a quick quote and a handshake. Here are the four questions homeowners ask us most often, and honest answers to each.

What Is the Best Roofing Material?

There's no single best material. The right one depends on your budget, the style of your home, the climate where you live, and how long you plan to own the property. In Middle Tennessee specifically, the four most common residential options are asphalt shingles, metal roofing, metal shingles, and (occasionally) tile or slate on higher-end homes.

For most homeowners staying in their home long-term, metal makes the most financial sense over the lifespan of the roof. For short-term ownership, asphalt is the more economical choice upfront. A good roofing contractor will walk through the trade-offs with you honestly instead of pushing a single product.

How Much Will a New Roof Cost?

Cost depends on three things: the size and complexity of your roof, the material you choose, and the condition of the existing structure underneath. Real ranges for a typical Middle Tennessee home:

  • Asphalt shingles: $3 to $7 per square foot installed
  • Metal roofing: $7 to $14 per square foot installed
  • Premium metals (copper, zinc): $15 to $25+ per square foot installed

For a 2,000 sq ft roof, asphalt typically runs $6,000 to $14,000, and metal runs $14,000 to $28,000. The honest math: metal costs more upfront, but lasts 2 to 3 times longer, so the lifetime cost often favors metal.

Does My Existing Roof Need to Be Removed Before Installing a New One?

Not always, but yes in most cases. Some jurisdictions allow a new roof to be installed over an existing one (a roof-over), but it's almost always better to tear off the old roof completely. The reason: you can't inspect the decking underneath for rot, water damage, or fastener problems without removing the old material first. Skipping that step means installing a new roof over hidden problems that will eventually cause leaks or structural issues.

For metal roof installations specifically, tear-off is essentially always required because the new system needs a clean, sound deck to attach to.

How Long Will My New Roof Last?

Lifespan varies dramatically by material:

  • Asphalt shingles: 15 to 30 years
  • Metal roofing (standing seam, classic panel): 50 to 75+ years
  • Metal shingles: 40 to 60 years
  • Copper or zinc: 80 to 100+ years
  • Slate or tile: 50 to 100+ years

Installation quality matters as much as material choice. A poorly installed metal roof can fail in 10 years; a well-installed one can outlast its 75-year material warranty. Choose the contractor as carefully as the material.

Frequently Asked Questions

Does a thicker gauge metal roof cost significantly more?

The material cost difference between gauges is real but not dramatic. Going from 26 to 24 gauge typically adds $1.50–$3.00 per square foot to the project. On a 2,000 sq ft roof, that's roughly $3,000–$6,000 more — but you're getting a meaningfully more durable roof that may save money on repairs over decades.

Is 29 gauge metal roofing good enough for a house?

We generally don't recommend 29 gauge for primary residences in Nashville. While it works fine for barns, carports, and outbuildings, it's thinner and more susceptible to denting from hail — and Nashville gets plenty of hail. The cost difference between 29 and 26 gauge is modest compared to the performance gap.

What gauge metal roof is best for Nashville homes?

For most Nashville residential projects, 26 gauge is the standard choice. It provides excellent wind and hail resistance for Middle Tennessee's climate at a reasonable price point. 24 gauge is the premium option for homeowners who want maximum durability and dent resistance.
