Roof Replacement: Costs, Materials & Timing

Roof replacement cost is driven by roof size (in “squares”), material, pitch, and how many old layers must be torn off. Estimate yours below, then review the key decisions.

sq ft

Total roof surface area in square feet (1 roofing square = 100 sq ft). A typical 2,000 sq ft house has roughly 2,000–2,400 sq ft of roof surface.

Architectural shingles are the most common residential choice. Metal and tile cost more upfront but last longer.

Taller homes require more safety equipment and scaffolding, increasing labor cost.

Steep pitches require special safety equipment and slow down installation, adding labor cost.

Most codes allow only 2 shingle layers. Tearing off old material adds labor and disposal cost but is often required.

Material and size

Roofs are measured in squares (100 sq ft each). Asphalt shingles are the most common and affordable; metal, tile, and slate cost more but last longer. A steeper, more complex roof costs more to work on safely.

Tear-off (removing old layers) and disposal add cost but are often necessary and sometimes required by code.

Repair vs. replace

Localized damage may be repairable, but widespread wear, multiple leaks, or a roof near the end of its life usually favors replacement. Get a professional inspection before deciding.

Frequently asked questions

How long does a roof last?

It varies by material and climate: asphalt shingles commonly last around 15–25 years, while metal and tile can last much longer. Have a pro assess your specific roof.

Is a metal roof worth the extra cost?

Metal costs more upfront but lasts longer and can improve energy efficiency. Whether it pays off depends on how long you’ll stay and your climate.
