How much does a complete roof installation typically cost?

A complete roof installation cost is based on your roof’s size, design, and chosen system, and it’s confirmed after an on-site inspection. The biggest driver is the overall scope of work from tear-off through the new components and finishing details. When a roof is near end of life or leaking in multiple sections, replacement often costs less long term than repeating repairs. Our team regularly installs shingle, metal, and flat/TPO systems in the Birmingham area. A common surprise is hidden decking or moisture damage found during tear-off, which can change the final price; financing and seasonal instant rebates (for example, $2,000 off eligible whole-home replacements) are available.

Watch for these cost factors during your estimate:

• Roof square footage and waste factor
• Material choice (shingle, metal, TPO) and warranty level
• Pitch, stories, and layout complexity
• Decking replacement, flashing details, and ventilation/code upgrades
