How to Compare Roofing Estimates Without Getting Ripped Off

"Get three estimates" isn't enough

Getting multiple estimates is smart. But three bids are only useful if you know what makes them different, and most homeowners compare roofing quotes the way they compare car prices — they read the number at the bottom.

Roofing quotes don't work that way. Two $18,000 quotes can use completely different materials, carry different warranties, come with different insurance coverage, and leave you holding completely different levels of risk.

Here's what to actually look at.

Material specs first

Every quote should spell out:

• Manufacturer and product line. "Owens Corning Duration" is a product. "Architectural shingles" isn't. Demand specifics.
• Weight / thickness. Standard architectural and premium architectural shingles have real differences in durability and warranty.
• Impact-resistance rating. Class 3 vs Class 4. Class 4 costs more but earns you an insurance discount.
• Starter strip and ridge cap. These are separate products from the field shingle. If the quote doesn't list them, they might be substituted with cheaper product or skipped.
• Underlayment type. Synthetic outlasts felt. Type matters.
• Ice and water shield. Required by code in some zones. Spec it, don't assume.

If two quotes list different materials, the cheaper one isn't cheaper. It's a different product. Match the materials before you compare price.

Warranty — both halves

Two parts matter:

Manufacturer warranty. Covers material defects. Standard on architectural shingles is 25 to 30 years; premium products go 50 years or "lifetime." The catch: the contractor has to be an authorized installer. An unauthorized install can void the manufacturer warranty.

Workmanship warranty. Covers installation errors. That's all on the contractor. Some offer a year. Reputable contractors offer 5 to 10. If the quote doesn't mention it, ask.

Insurance and credentials

Before anyone steps on your roof:

• General liability. At least $1M per occurrence. Ask for the certificate, don't take their word for it.
• Workers' comp. If an uninsured worker gets hurt on your property, you can be on the hook. Verify it's current.
• Insurance certificates. Ask for current GL ($1M+ per occurrence) and workers' comp. Get the actual certificates, not just verbal assurance.

A contractor who drags their feet on any of these has something to hide.

Red flags in the quote

Extremely low price. Labor and materials have floors. A quote 30 percent below everybody else is using worse materials, underpaying labor, cutting corners, or all three.

No written scope. Verbal agreements are worthless. Materials, process, timeline, warranty — all in writing.

Pressure to sign today. Real contractors don't expire quotes overnight. Pressure is a tactic.

Large upfront payment. Standard is a 10 to 30 percent deposit to order materials, balance on completion. Anybody demanding 50 percent or more upfront is a problem.

No physical address. Chaser shops set up temporarily and leave when the jobs dry up. A local contractor with a real office is accountable.

Insurance claims complicate it

If insurance is paying:

The carrier's approval is the real quote. They approve a specific scope and dollar amount. The contractor's job is to work within that scope — or supplement for missed items.

Anybody offering to waive your deductible is committing a crime. That's insurance fraud in Texas, and it's a felony. It can void your claim. Walk away.

Ask if they'll attend the adjuster meeting. That's where the scope gets set. A contractor who attends and presents the full documented damage typically results in a more complete scope. Most don't do this.

The question nobody asks

"What happens if there's a problem after the job is done?"

Ask it straight. A contractor with a real answer — specific warranty, named contact, documented process — is running a real business. Vague answers and deflection are warnings.

The good contractors want this conversation because they're confident in their answer.
