Roofing Cost Guide & Contractor Comparison
Roof replacement is one of the largest home expenses. Learn what drives costs, how to evaluate bids, and what questions every homeowner should ask.
What You Need to Know About Roofing
A roof replacement is a major investment that protects everything beneath it. Costs vary based on roof size, pitch, material choice, and local labor rates. This guide walks you through the key cost drivers, how to spot a reputable contractor, and the red flags that signal a bad bid.
Project Scope & Pricing Tiers
Repair / partial replacement
$500 – $3,000
Patching damaged sections, replacing flashing, fixing leaks — not a full replacement.
Standard replacement
$5,500 – $10,000
Full tear-off and replacement with architectural asphalt shingles on an average home.
Premium material replacement
$10,000 – $30,000+
Metal roofing, slate, tile, or cedar shake on larger or complex roof structures.
What Drives the Cost
Roofing is priced per 'square' (100 sq ft). An average home has 20–30 squares.
3-tab asphalt $3.50–$5/sq ft; architectural shingles $4–$7; metal $7–$14; tile $10–$20+.
Steep roofs require safety equipment and more labor — typically adding 20–40% to costs.
Tearing off existing shingles adds $1–$2/sq ft. Most codes allow only 2 layers total.
Rotted or damaged decking boards are replaced at $2–$4/sq ft — often discovered during tear-off.
Chimney, skylight, and valley flashing replacement adds $200–$1,500 per feature.
Impact level indicates how much this factor typically affects total project cost.
How to Evaluate Contractor Bids
Never pay more than 10% upfront
Storm chasers and scam contractors often demand large deposits. Reputable roofers typically collect payment upon completion.
Verify manufacturer certification
GAF Master Elite, Owens Corning Preferred, or CertainTeed SELECT ShingleMaster status means the contractor is trained and offers extended warranties.
Ask about decking inspection
A good contractor will inspect decking during tear-off and provide a per-board price for any replacements needed.
Confirm permit and inspection process
Most jurisdictions require a permit for roof replacement. Ask who pulls the permit and whether a final inspection is included.
Get the warranty in writing
Understand both the material warranty (from manufacturer) and the workmanship warranty (from contractor). Workmanship warranties vary from 1 to 25 years.
