Every roofing contractor in New York will tell you they’re licensed, insured, experienced, and focused on quality. That’s not a differentiator — that’s the baseline sales pitch. The questions that actually separate a contractor worth trusting from one worth avoiding aren’t the ones most homeowners think to ask.
This isn’t the generic checklist you’ve already seen. These are the questions that expose how a contractor actually operates — not how they present themselves in a driveway conversation.
We’re Abraham Roofing, based in Lynbrook. We’ve been working on roofs in Nassau County for over 30 years. We’re sharing these questions because a homeowner who knows what to ask ends up with a better roof — whoever they hire.
Question 1: Who Pulls the Permit, and Is That Cost in the Quote?
This is the single most revealing question on this list — and most homeowners never ask it.
In Nassau County, roofing work above a certain scope requires a building permit. The permit ties the job to an inspection, which protects you: it creates a documented record that the work met code at the time it was done. That matters when you sell the house, when you file an insurance claim, and when something goes wrong years later.
Some contractors skip the permit entirely to move faster and avoid the inspection. Others pull it but leave it out of the written quote so it shows up as a surprise line item after you’ve already committed. A few try to have the homeowner pull their own permit — which is legal in some cases but shifts the liability for the work onto you.
The right answer: the contractor pulls the permit, it’s included in the written quote, and the job doesn’t start until it’s approved. Any other answer is a conversation worth continuing before you sign.
Question 2: Who Is Actually Doing the Work?
Not “does your company do roofing.” Specifically: will the crew installing my roof be your employees, or subcontractors you hire for this job?
This distinction matters more than most homeowners realize. A contractor who uses their own trained, insured crew has direct control over quality and is directly accountable if something goes wrong. A contractor who subcontracts to whoever’s available that week has a fundamentally different relationship to the work — and to the warranty claim you might need to file two years from now.
Neither model is automatically bad. Subcontracting is common and legitimate. But you should know which one you’re dealing with. Follow-up questions worth asking: How long have the crews you use worked with you? Are they covered under your liability policy? Will a project manager from your company be on-site during installation?
A contractor who gets defensive about this question is telling you something.
Question 3: What Happens If You Find Rotted Decking Once the Shingles Come Off?
This is the question that separates contractors who plan for what they’ll actually find from ones who quote for the best-case scenario and charge for everything else as a surprise.
Rotted or soft decking is common on Long Island homes, especially ones approaching 20 years old — freeze-thaw cycling, ice dam damage, and trapped moisture all work on decking from underneath while shingles above look relatively intact. A thorough contractor knows this and has a clear policy for how it gets handled: they’ll tell you upfront what the per-sheet replacement cost is, how they document what they find, and how they notify you before any additional work happens.
A contractor who either dismisses the question (“we’ll deal with it if we see it”) or gives you a vague non-answer on pricing doesn’t have a process. That’s how a $12,000 quote becomes a $17,000 invoice.
Question 4: Can I See Your Certificate of Insurance — Right Now?
Not “yes we’re insured.” The actual certificate, showing current general liability coverage and workers’ compensation, with your contractor’s name on it.
This matters because if a crew member is injured on your property and the contractor’s workers’ comp has lapsed — or if they’re misclassified as independent contractors to avoid coverage — the liability can land on your homeowner’s policy. It happens. Nassau County homeowners have faced exactly this situation.
A legitimate contractor keeps their certificate of insurance current and can produce it immediately. If the response is “we’ll email it to you” and it never arrives, or if the certificate they provide has expired dates, walk away. This is not paperwork pedantry — it’s the difference between a roofing job and a liability exposure.
Question 5: What Does Your Workmanship Warranty Actually Cover?
Not the manufacturer warranty on the shingles. The contractor’s own warranty on the installation — the labor, the flashing, the underlayment, the seals around every penetration in the roof.
Ask these follow-up questions specifically:
How long does your workmanship warranty last? (Anything under five years on a full replacement is below standard.)
Is it in writing in the contract? (If it’s verbal, it doesn’t exist.)
Who honors it if your company changes ownership or goes out of business? (More common than homeowners expect — especially with smaller operators who run lean.)
What specifically voids it? (Poor attic ventilation is the most common voiding condition, and most contractors don’t tell you that upfront. If your attic isn’t properly ventilated, shingles fail faster — and the contractor may argue that voids their warranty on the installation.)
Abraham Roofing’s workmanship warranty is written into every contract. If you’re comparing contractors, that’s the baseline to hold them to.
Question 6: What’s Your Timeline — and What Causes It to Change?
A roofing project with a clear timeline is a sign of a contractor who’s organized. Vague timelines are a sign of a contractor who’s overcommitted, disorganized, or both.
Ask for a specific start date, an estimated completion date, and the conditions that would change either. Weather is a legitimate variable — no reputable contractor installs shingles in rain. But “we’ll get to you when we get to you” isn’t a schedule, and a crew that starts your job and then disappears for three days to finish someone else’s is a real and common problem.
Also ask: will you be working every day until the job is complete, or is it possible the crew will leave mid-job? If the roof is open — decking exposed, old shingles stripped — and rain comes while the crew is somewhere else, you have a problem.
Question 7: How Do You Handle Cleanup and Debris Removal?
Whose dumpster is it, and whose name is the permit on for disposal? In Nassau County, debris disposal has specific requirements — shingle waste and underlayment can’t just go anywhere. A contractor who’s vague about debris handling is often either charging you separately for it (surprise invoice) or cutting corners on legal disposal.
Ask specifically: is haul-away included in the quote? Who is responsible if roofing nails are found in the lawn or driveway after the job? What’s the process for protecting landscaping, windows, and HVAC equipment during tear-off?
A contractor who has done this work properly hundreds of times has answers to all of these without hesitating. The ones who haven’t will give you a vague “we take care of everything” that turns out to mean very little.
Question 8: Do You Offer a Drone or Infrared Inspection, or Just a Visual Walk-Up?
This one separates contractors who’ve updated their process from ones still working the way they worked in 2005.
Drone-based roof surveys give a complete aerial view of every section of the roof — valleys, ridgelines, penetrations — without the physical limitation of where an inspector can safely walk. Infrared scanning detects moisture trapped under shingles that a visual inspection misses entirely. Both tools change the quality of a repair or replacement recommendation because they’re based on more complete information.
A contractor who only does a visual walk from the driveway and a quick ladder check is working with less data than they could be. On a Long Island home where salt-air fastener corrosion and ice dam damage often hide under intact-looking surfaces, that matters.
This isn’t a dealbreaker if everything else checks out — but a contractor who uses modern diagnostic tools is telling you something about how they approach the job.
Question 9: What Materials Are You Specifying, and Why?
Not just “architectural shingles.” The specific product line, the manufacturer, the weight class, and — critically — why they’re recommending that product for your specific roof.
There’s a meaningful difference between a 30-year architectural shingle and a 50-year Class 4 impact-resistant shingle. There’s a meaningful difference between standard underlayment and synthetic underlayment rated for ice-dam conditions. A contractor who can explain why they’re specifying what they’re specifying — and what the alternatives are — is a contractor who understands roofing. A contractor who says “we use GAF” and stops there hasn’t told you anything.
Also ask whether the specified materials are compatible with your current attic ventilation. Certain high-performance shingles require specific net free area ventilation ratios to perform as warranted — and most homeowners have no idea whether their attic meets that standard. The contractor should.
Question 10: Will You Walk Me Through the Completed Job Before I Make Final Payment?
The answer should be yes, without hesitation.
A professional roofing job ends with a walkthrough — contractor and homeowner, together, checking that every section is complete, every penetration is sealed, gutters are reattached and clear, cleanup is done, and the property looks better than when the crew arrived. Final payment happens after that walkthrough, not before it.
If a contractor wants full payment before the walkthrough — or before the job is complete — that’s the last question you need to ask. The answer tells you everything.
Why These Questions Matter More in Lynbrook
Nassau County’s housing stock, coastal exposure, and local permit requirements create a specific set of conditions that make contractor vetting more consequential here than in a lot of other markets. Salt-air corrosion, ice dam history, and the specific failure patterns on postwar Long Island homes are things a local contractor either knows or doesn’t — and these questions help you find out which one you’re dealing with before you’ve committed to anything.

The right questions reveal how a contractor handles permits, crews, unexpected decking damage, insurance, warranties, materials, timelines, cleanup, inspections, and the completed project. Taking the time to get clear answers before signing a contract can help you avoid unexpected costs and protect your home for years to come.
