How to hire a roofing pro in United States
- Verify the state contractor license where required (Florida and California have specific roofing classifications; requirements vary widely by state)
- Demand certificates of general liability and workers' comp insurance — roofing is a high-injury trade and uninsured crews are your risk
- Get 3 like-for-like bids covering tear-off, underlayment, ice-and-water shield, flashing replacement and a per-sheet price for deck repair
- Check manufacturer certifications (e.g. GAF or Owens Corning credentialed installers) — they unlock longer material warranties
- Confirm the contractor pulls the building permit, not you
- For insurance claims, get your own adjuster's assessment before signing any assignment-of-benefits paperwork
- Get both the manufacturer warranty and a written workmanship warranty (5-10 years)
Roofing licenses are set at state level — some states (Florida, California) require a dedicated roofing classification while others have no licensing at all. Workers' comp verification matters everywhere: roofing has among the highest injury rates of any trade, and homeowners can be exposed by uninsured crews.

Frequently asked questions
Should gutters be replaced at the same time as the roof?
Often worth it: the access equipment is already up, edge details integrate cleanly, and combined pricing beats two separate jobs. If your gutters are under ten years old and sound, keep them — but have the roofer protect them during tear-off and note their condition in writing.
Do I need a permit for roof work?
Full replacements commonly require a building permit or regulatory compliance; small like-for-like repairs usually don't. Rules vary by country and municipality, and a legitimate contractor will know and handle the paperwork — treat 'we don't need a permit' on a full reroof as a flag to double-check.
How long does a roof replacement take?
A straightforward single-family roof takes 1-3 days for asphalt shingles or metal sheeting, and up to 1-2 weeks for tile, slate or complex multi-plane roofs. Weather delays are normal — a competent crew will never strip more roof than they can waterproof the same day.
What is flashing and why do most leaks start there?
Flashing is the metal detailing that seals joints — around chimneys, valleys, vents, skylights and wall junctions. These joints move and collect water flow, so flashing fails long before the main covering. If a roofer proposes reusing old flashing on a full replacement, push back.
When is the best time of year to replace a roof?
Dry, settled weather — and before your region's storm or rainy season, not after it starts. Roofers book out weeks or months ahead of peak season, so schedule inspections early; shoulder-season slots are often cheaper and easier to get.
How much does a new roof cost?
It scales with roof area, pitch, number of storeys, access, and material. Basic asphalt shingle or concrete tile sits at the bottom of the range; metal, slate and clay cost two to four times more. Tear-off of the old covering, disposal, scaffolding or edge protection, and hidden deck repairs are the lines that move a quote most — make sure all four are priced before comparing.
How much does a roof replacement cost in the US?
Most homeowners pay $9,000-$18,000 for a standard asphalt shingle replacement, with the full range running roughly $6,000 to $30,000+ depending on size, pitch and region. Metal roofs typically run $15,000-$45,000. Per-square (100 sq ft) pricing of $450-$1,100 installed is the common quoting unit.
Does homeowners insurance cover roof replacement?
For sudden storm damage, usually yes — but many insurers now pay only depreciated actual-cash-value on roofs past 10-15 years old, not full replacement cost. Check your policy's roof schedule, document damage immediately, and be cautious with contractors who want to 'handle the claim for you.'
