To replace roofing, you need to hire a contractor, choose your materials, and get the work done safely. Most homeowners spend between $5,868 and $13,217 on a full roof replacement, according to RubyHome (2025). The process takes a few days to a week depending on your roof size and material choice. Your roof is one of your home’s most important parts, so replacing it the right way matters. Many homeowners do this work when their roof leaks or gets storm damage.
When Do You Need to Replace Your Roof?
Your roof does not last forever. According to RubyHome (2025), the average roof lifespan ranges from 25 to 50 years. Asphalt shingles last 20 to 30 years, while metal roofs can last 40 to 80 years.
Most roofs are replaced around 19 years old. Watch for these signs: leaks inside your home, missing shingles, or dark spots on the roof.

Get a Professional Contractor
Hiring a roofer is the best choice for most homeowners. According to This Old House (2025), 79% of homeowners who did roof renovation hired contractors. The average cost for roof installation ranges from $4 to $40 per square foot, according to RubyHome (2025).
Ask contractors for free estimates. Get at least three quotes before choosing. Check their licenses and reviews online.
What Happens During Replacement
The roofer will remove your old roof, check the wood underneath, and install new materials. This protects your home from leaks and storm damage.
Most replacements take 3 to 5 days. Bad weather can delay the work. Your contractor should clean up debris when done and explain your new roof’s warranty and care needs.
