Roofing has more than its share of fly-by-night operators, especially after a storm rolls through and the out-of-town trucks show up. The frustrating part is that a bad roof and a good one can look identical from the driveway for the first year or two. The difference shows up later, when the flashing detail nobody checked starts leaking and the company that installed it is nowhere to be found. A few direct questions up front tell you most of what you need to know. Here are the ten we would ask, and the answers you want to hear.
Credentials and accountability
1. Are you registered as a contractor in Pennsylvania, and what is your registration number? The state requires home improvement contractors to register, and a legitimate one will give you the number without a pause. You can verify it yourself.
2. Are you insured, and can you show me a current certificate? You want both general liability and workers' compensation. If an uninsured worker is hurt on your roof, or your house is damaged, you do not want that landing on your homeowner's policy. Ask for the certificate, do not just take the yes.
3. Are you certified by the manufacturer whose shingles you install? Manufacturer certification is not just a badge. It ties the installer to the manufacturer's standards and is often what keeps the material warranty valid. A real business answers all three of these without hesitating.
Scope and workmanship
4. Is this a full tear-off or a layover? A tear-off lets us inspect and fix the decking; a layover hides problems under new shingles. If someone quotes a layover to come in cheaper, know what you are trading away.
5. What underlayment, flashing, and ventilation are included? These are the details that decide whether a roof lasts, and they are also the easiest places to cut costs invisibly. You want new flashing, quality synthetic underlayment, ice-and-water shield where our winters need it, and ventilation corrected to spec.
6. What happens if you find rotten decking after tear-off? You want a clear per-sheet price agreed up front, and a promise that they will show you before replacing anything, so a real repair does not become a vague, inflated change order.
Warranty and the paper trail
7. What does your workmanship warranty cover, and for how long? The material warranty comes from the manufacturer; the workmanship warranty comes from the roofer, and it is only as good as the roofer still being in business. Get its terms in writing.
8. Will I get a written, itemized estimate before any work starts? Everything you have discussed should be on paper, in the scope, before you sign. A handshake and a round number are how surprises happen.
9. Who is actually on my roof, your crew or a subcontractor? Either can be fine, but you deserve to know, and to know that whoever it is carries the same insurance and answers to the same warranty.
The storm-chaser test
10. Where is your local office, and will I be able to reach you next year? This is the single most telling question after a storm. A warranty is worthless if the company has moved on to the next disaster three states away. You want a roofer with roots here, one you can drive to and call back.
And the question that ends the conversation if it comes up: do you promise to waive my deductible? Anyone who offers to waive or absorb your insurance deductible is describing insurance fraud, and that is your cue to walk, no matter how good the rest of the pitch sounded.
What good answers feel like
You are not looking for perfect, rehearsed responses. You are looking for a roofer who is comfortable being pinned down. Someone who gives you numbers, shows you documents, puts the scope in writing, and does not flinch when you ask about insurance or warranties is someone who plans to be accountable. Someone who gets vague, rushes you, or leans on a discount that expires today is telling you how the job will go if something turns up later. Trust that signal.
Common questions
Why does a local office matter so much?
Because a warranty is only as good as the company still being here to honor it. Out-of-town crews that appear after a storm are often gone before the next one, and a workmanship warranty you cannot collect on is just ink on paper.
Should I always get multiple quotes?
Getting two or three is smart, but compare the scope, not just the price. The cheapest bid is often the one leaving the most out. When two quotes are far apart, the gap is usually explained by what the lower one does not include.
How do I verify a contractor's PA registration?
Pennsylvania maintains a public registry of home improvement contractors, and you can look up the registration number a contractor gives you. If they will not provide a number, that is your answer.
