Roofing Quote Comparison Analyzer
Enter up to 3 roofing contractor quotes and this tool will normalize them side-by-side — price per square, warranty, and material grade — so you can compare apples to apples. You decide what matters most; we just do the math honestly.
1Quote 1
Company name — e.g. ABC Roofing
2Quote 2
Company name — e.g. XYZ Roofing
3Quote 3
Company name — e.g. 123 Roofers
Scores are normalized only against the quotes you enter. Material grade: Architectural Asphalt = C, Class 4 Impact = B, Metal = A, TPO = A. Overall = 40% price + 30% warranty + 30% material.
Fill in at least two quotes (total price + roof size) and hit Compare Quotes to see the normalized side-by-side breakdown.
The Lowest Price Isn't Always the Best Roofing Deal
This analyzer shows you the math — but a roof is a 25-to-40-year investment, and a low bid can cost you far more in the long run. Before you sign anything, verify these four things on every quote:
- License. Confirm the contractor's Oklahoma license (CIB number) with the state — unlicensed "roofers" vanish when problems appear.
- Insurance. Ask for proof of general liability and workers' compensation insurance. If a crew member gets hurt on your roof and the contractor is uninsured, you can be held liable.
- Manufacturer certifications. Certified contractors like Owens Corning Preferred meet factory installation standards — required for many shingle warranties to stay valid.
- Written warranty. Get it in writing: exactly what's covered, for how long, and whether it's transferable. Oklahoma only requires a 1-year workmanship warranty — anything less than that is a red flag.
Roofing Quote Questions, Answered
How do I know which roofing quote is the best deal?
Don't compare total prices alone — compare price per square, which is the total price divided by the roof size in squares. Two quotes can look similar but differ a lot once roof size is normalized. Also weigh warranty length, material grade, and what each bid includes: tear-off, decking replacement, drip edge, and cleanup.
What should I check before accepting the lowest roofing bid?
Verify the contractor's Oklahoma license (CIB number), general liability and workers' compensation insurance, manufacturer certifications like Owens Corning Preferred, and a written warranty that spells out exactly what is covered and for how long. The lowest bid is no bargain if the company can't back its work.
How is the price per square calculated?
Divide the total quote by the roof size in squares — one square equals 100 square feet. For example, a $12,000 quote on a 20-square roof is $600 per square. This analyzer computes it automatically so you can compare quotes on an apples-to-apples basis.
Why might the lowest quote not be the best value?
Cheaper bids often mean thinner shingles, no allowance for decking repairs, shorter warranties, or uninsured crews. Proof Construction has served Oklahoma since 2015 as an Owens Corning Preferred contractor (CIB #80004070) with a 4.9-star rating from 127+ reviews and a 3-year workmanship warranty — triple the state minimum.
