Question 1

How much does roof replacement cost in 2026?

Accepted Answer

Most roof replacement planning ranges start around $3-$12 per square foot for common residential roofing, while premium systems like standing seam metal, tile, cedar, and slate can cost more. Final pricing depends on pitch, waste, tear-off, roof complexity, access, and material choice.

Question 2

What is a roofing square?

Accepted Answer

One roofing square equals 100 square feet of roof surface. Contractors often estimate materials and labor by the square, not by home footprint square footage.

Question 3

How much roofing waste should I add?

Accepted Answer

Simple roofs often need about 8% waste, moderate roofs around 12%, and complex cut-up roofs about 17% or more. Waste covers cuts, starter/ridge pieces, and material around roof details.

Question 4

What is the cheapest roofing material?

Accepted Answer

Three-tab asphalt shingles are the cheapest roofing material at $3.50-$5.50/sqft installed ($350-$550 per square). For a 2,000 sq ft roof (20 squares), that's $7,000-$11,000 total. Architectural asphalt costs slightly more at $4.50-$8/sqft but lasts 10-15 years longer.

Question 5

Is a metal roof worth the cost?

Accepted Answer

A metal roof is worth the cost if you plan to stay 15+ years. Metal roofing costs $7-$14/sqft installed vs $4.50-$8 for architectural asphalt, but lasts 50+ years vs 20-25 for asphalt. Metal roofs also reduce cooling costs by 10-25%, resist hail and high winds, and may qualify for insurance discounts.

Question 6

How long does a roof last?

Accepted Answer

Roof lifespan varies by material: 3-tab asphalt 15-20 years, architectural asphalt 25-30 years, metal roofing 50+ years, clay/concrete tile 50-100 years, slate 75-150+ years, and cedar shakes 20-30 years. Climate, ventilation, installation quality, and maintenance significantly affect actual lifespan.
