A roof replacement is one of the largest single checks most homeowners write, and the industry attracts more than its share of storm-chasing operators. This guide covers how to decide between repair and replacement, what legitimately moves the price, and how to verify a roofer before anyone climbs a ladder.
Fair Price Pros publishes planning guides for roofing projects but is not yet accepting roofing requests through the marketplace. Use this guide to plan and compare written proposals; leave your interest and we will note demand as new trades open.
Define the scope before you call
Start with what you can observe from the ground or an upstairs window: missing or curling shingles, granules collecting in gutters, sagging lines, or stains on ceilings inside. Note the roof's approximate age, the material (asphalt shingle, metal, tile, flat membrane), and how many layers you believe are on it — many codes limit roofs to two layers.
If you have an active leak, contain the interior damage and document it with photos before any repair. That documentation matters for insurance and for comparing contractor diagnoses.
Repair versus replacement
Isolated damage on a roof with years of life left — a few missing shingles, a failed pipe boot, flashing around one chimney — is usually a repair. Widespread granule loss, curling across multiple slopes, repeated leaks in different areas, or a roof at the end of its expected life points to replacement.
Asphalt shingle roofs commonly last 20 to 30 years depending on grade and climate; metal and tile last longer. Ask any contractor recommending replacement to show you the specific failure evidence, photographed, not just to say the roof is old.
What legitimately changes a quote
Price drivers include roof area and pitch, stories and access, the number of layers to tear off, decking repairs discovered after tear-off, material grade, underlayment and ice-barrier requirements in cold climates, ventilation corrections, and flashing and chimney work. Disposal fees for tear-off material are real and belong in the quote.
Decking is the classic unknown: rotten sheathing can only be found after tear-off. Good quotes state a per-sheet price for decking replacement up front so the final bill is not a surprise.
Comparing itemized bids
Written quotes should name the shingle or material manufacturer and product line, underlayment type, ice-and-water barrier locations, ventilation plan, flashing scope, tear-off and disposal, decking replacement unit price, and warranty terms. Manufacturer system warranties often require specific component combinations — ask whether the quoted assembly qualifies.
Separate the workmanship warranty (from the contractor, covering installation) from the material warranty (from the manufacturer). A lifetime shingle on a poor installation is still a poor roof.
Credentials, insurance, and storm-chaser red flags
Roofing licensing varies by state — some states license roofers specifically, some fold it into general contracting, and some regulate at the local level. Check our state guide for your lookup tool. Always confirm general liability and workers' compensation insurance directly with the insurer; roofing is high-risk work and an uninsured crew on your roof is your liability.
After major storms, out-of-area crews solicit door to door. Red flags: pressure to sign immediately, offers to cover or hide your insurance deductible, requests for large up-front payments, and no local address or verifiable license. Never sign an assignment of benefits you do not understand.
Questions to ask before signing
Ask: What is your license or registration number, and can I verify your insurance directly with the carrier? What is the per-sheet price for decking replacement? Which manufacturer warranty does this assembly qualify for, and who registers it? Who is my on-site supervisor? What is the payment schedule — and is any of it due before materials are delivered?
