Essential Questions to Ask a Roofing Contractor

Knowing what questions to ask a roofing company protects you from costly mistakes and helps you separate reputable roofers from corner-cutters. Here are the essential questions — and why each one matters.

Are you licensed and insured in Virginia? Ask for proof of both general liability and workers’ compensation — this protects you from liability if something goes wrong.
Do you offer a workmanship warranty, and how long does it last? This covers installation errors, the most common source of roof problems.
What manufacturer warranty comes with the materials? Ask whether it’s prorated and whether labor is included.
Will you provide a written, itemized estimate? You want the full scope in writing, not a vague total.
Is this a full tear-off or a layover? Roofing over an old layer can shorten roof life and affect warranties.
How will you handle flashing, ventilation, and rotted decking? New flashing and proper ventilation are essential to a lasting roof.
Who pulls the permit, and is permitting included? A reputable roofer handles local permitting.
How do you handle cleanup and debris disposal, including nails?
Can you provide local references and reviews from recent projects?
Do you offer a free inspection and estimate?

Why These Questions Matter

The answers reveal whether a roofing company does complete, code-correct work or cuts corners to win on price. Red flags include no license or insurance, vague scopes, high-pressure sales tactics, large upfront deposits, and “we’ll just seal it” as the answer to a leak. A confident, reputable roofer answers every question openly and puts the details in writing.

Ask all ten questions and watch how the answers arrive. The good contractors get more comfortable as the list goes on — the ones to walk away from get more irritated. Ten questions, five minutes, and you know exactly who is standing in your driveway.

Frequently Asked Questions

What is the most important question to ask a roofing company?

Start with license and insurance — with proof of both general liability and workers’ compensation. It is the non-negotiable baseline: it protects you from liability if something goes wrong on your property.

Why does the tear-off vs. layover question matter?

Roofing over an old layer (layover) can shorten the new roof’s life, hide deck damage, and affect or void warranties. A reputable contractor will explain whether a full tear-off is required for your home and why.

What red flags should I watch for when interviewing roofers?

No license or insurance, vague scopes, high-pressure sales tactics, large upfront deposits, and “we’ll just seal it” as the answer to a leak. A confident, reputable roofer answers questions openly and puts the details in writing.

Should a roofing company provide a free inspection?

A free inspection and estimate is standard practice among reputable local roofers — it signals the company leads with honesty rather than high-pressure sales. Sam Construction Group USA offers both across Northern Virginia: (571) 373-6388.
