Choosing a Roofing Contractor in Rockland County: 12 Questions Every Homeowner Should Ask
There is a particular moment every Rockland County homeowner knows. A branch comes down in a March windstorm, or a stain shows up on the ceiling after a February thaw, and suddenly you need a roofer, and you need one soon. That is exactly the moment when the wrong decision gets made, not because homeowners are careless, but because urgency and unfamiliarity make a poor combination.
Our seasons here do their part too. Snow load and ice dams take their toll every winter, spring brings the freeze damage out into the open, summer storms roll through with wind and hail, and fall leaves clog the gutters that were fine all August. Somewhere in that cycle, almost every homeowner in Rockland County eventually needs to hire a roofer, and the truth is that the county makes it harder than it should be to tell a good one from a risky one at a glance.
Here is a number worth sitting with: there are 2,128 active home improvement licenses in Rockland County right now, according to Rockland County Consumer Protection and Weights & Measures. Some of those businesses have been roofing here since before we were, and we have been doing this since 1979. Some were formed last spring. The county license does not tell you which is which. It confirms that a business met a threshold, not that it will install your roof correctly.
We have spent over four decades answering these exact questions from neighbors across Rockland County, so we put together the twelve that matter most, in roughly the order they tell you the most per minute spent asking.
1. What Is Your Rockland County Home Improvement License Number?
Under Chapter 286 of the Laws of Rockland County, any person or business performing home improvement work on a private residence of six families or fewer must hold a license issued by the county’s Office of Consumer Protection, and roofs are named explicitly in that definition. This is not a suggestion. Chapter 286 authorizes Consumer Protection to seize and impound vehicles, tools, and equipment used by an unlicensed contractor, and it also prohibits a licensed contractor from employing unlicensed subcontractors, which is the provision that catches the most homeowners off guard, since they assume the company’s license covers everyone working under it.
Verify the number yourself against the county’s Licensed Businesses directory. Do not accept a photograph of a license card as proof. The county adopted an updated version of Chapter 286 effective May 14, 2026, so a contractor’s familiarity with the current rules is itself a useful signal about how closely they pay attention.
If you also own property across the state line in New Jersey, know that New Jersey does not license roofers; it registers them. Every home improvement business there must register annually with the New Jersey Division of Consumer Affairs and display a 13-digit number beginning with 13VH on contracts, estimates, and advertising. Since January 2024, under P.L. 2023, c. 237, registrants must also maintain a compliance bond or letter of credit, and subcontractors must hold their own registration too. A&J Reliable holds both credentials because we work both sides of the line.
2. Can I See Your Certificate of Insurance, Sent Directly From Your Agent?
Two different policies matter here, and they cover two very different risks. General liability covers damage to your property, things like a dropped bundle through a skylight or a truck backing into a stone wall. Workers’ compensation covers injury to the crew, and without it, an injured worker on your roof can quietly become your liability.
Ask the contractor to have their insurance agent email the certificate to you directly, with your name and address listed as certificate holder. A certificate forwarded by the contractor only tells you a policy existed on the date that document was generated. A certificate sent straight from the agent tells you it is in force today. Check the expiration date, and check that the named insured matches the business name on your contract exactly.
3. Who Is Actually Going to Be on My Roof?
Plenty of roofing companies sell the job with their own employees and then install it with subcontracted crews. That is not automatically a problem, but it changes who is accountable, and it triggers the Chapter 286 subcontractor licensing requirement we mentioned above.
Ask whether the installation crew will be W-2 employees or subcontractors. If subcontractors, ask for their Rockland County license numbers and their own workers’ compensation certificate. Ask who will be on site supervising the job, by name, and how often they will actually be there.
4. What Is Your Workmanship Warranty, in Years, in Writing?
There are two separate warranties on any roof, and homeowners routinely mix them up. The manufacturer warranty covers defects in the shingle itself, and honestly, manufacturing defects are rare. The workmanship warranty covers installation errors, and installation errors cause the overwhelming majority of premature roof failures we see. A beautiful manufacturer warranty is worth very little against a roof that leaks because a valley was cut wrong.
A standard contractor workmanship warranty runs one to ten years. Anything under two years should raise an eyebrow. Get the term, the exclusions, and the claim process in writing, in the contract itself, not on a website that can change tomorrow. Then ask the question that matters most of all: what happens to this warranty if the company closes?
5. Are You Certified by the Manufacturer Whose Shingle You Are Quoting?
Manufacturer certification is how a warranty survives the contractor, not just the shingle. GAF’s Master Elite designation is held by roughly 2 to 3 percent of roofing contractors in North America. Owens Corning’s Platinum Preferred program is invitation-only and covers a similarly small share. Both require verified licensing, insurance, a real track record, and annual recertification, not a one-time class.
The practical payoff is warranty access. GAF’s Golden Pledge limited warranty, which covers materials and workmanship on a non-prorated basis with GAF itself backing the labor, is only available through Master Elite contractors. Owens Corning’s Platinum Protection works the same way. A non-certified contractor simply cannot offer these, and standard tier warranties typically start prorating after year ten. Do not take a contractor’s word for their certification. Look the company up directly in the manufacturer’s contractor locator, since certification lapses and a logo on a truck is not proof of current standing.
6. How Will You Handle Permits in My Town?
This is the single biggest practical difference between roofing in Rockland County and roofing just across the state line in Bergen County, New Jersey, where the state code exempts most single-family reroofs from permitting entirely. In New York, reroofing is governed by the state Uniform Code but administered locally. Rockland County has five towns (Clarkstown, Haverstraw, Orangetown, Ramapo, and Stony Point) plus roughly eighteen villages. Every one of them runs its own building department with its own process and timeline.
- Ask which building department will issue your permit, who actually pulls it, whether the fee is already included in your quoted price, and roughly how long that particular department is taking right now. A contractor who has worked in Nyack knows Nyack's process from memory. A contractor who has to look it up is telling you something too. If your home sits in Nyack, Piermont, Grand View-on-Hudson, or Upper Nyack, historic district review is a separate question entirely, and it is worth asking before you settle on a material or a color, not after.
7. Can I See Three Local References From the Past Two Years, Plus Three From Ten Years Ago?
Recent references tell you how a company works today. Older references tell you how the roof actually held up, and whether the company still answered the phone when something went wrong in year six. Most homeowners only think to ask for the recent ones, but honestly, the older list tells you more.
Ask for addresses in your town or a neighboring one, not a general list pulled from a spreadsheet. Then ask each reference one specific question: did anything go wrong, and how did they handle it? Every job runs into some kind of problem eventually. What actually separates good contractors from the rest is the response. Our own testimonials page and project gallery show work across Rockland County and the surrounding counties, and we are glad to have you drive past any of it.
8. Can I See Photos of Your Work on a Home Like Mine?
Rockland County’s housing varies enormously from one town to the next. A crew that installs architectural asphalt on new construction in Pomona all week may never have touched a slate roof in Nyack or a copper valley on a Victorian in Piermont.
Ask for photographs of completed jobs on your roof type and architectural style, ideally with an address you could drive past yourself. Ask specifically to see close-ups of flashing details and valleys, not just wide shots of a finished slope, since flashing is where the craftsmanship really lives and where poor work likes to hide. If your home has slate, cedar, copper, or a flat or low-slope section, confirm the actual crew has handled that system before, not just the company in general.
9. Where Is Your Office?
Storm-chasing crews follow weather events from state to state, quote fast, install fast, and are gone before the first hard winter tests their work. A local business address, a landline, and a yard where the trucks actually sit tell you a company intends to be still reachable when you need them again.
Ask for the physical address and look it up yourself. A UPS Store mailbox, or a residential address two counties away, is worth knowing about. So is a phone number that only ever rings to a cell phone in someone’s truck. We have operated from 50 Second Ave in Nanuet since 1979, about fifteen minutes from New City, twenty from Nyack, and twenty-five from Suffern, and we plan on being there for a long while yet.
10. What Is Your Payment Schedule?
Payment structure is one of the most reliable predictors of trouble we know of. A reasonable structure looks like a modest deposit, a progress payment tied to a clearly defined milestone, and a final payment after your own walkthrough of the finished work. Large upfront deposits, cash-only requests, and demands for full payment before material even arrives on site are all reasons to keep looking elsewhere.
Chapter 286 and New York General Business Law both establish contract requirements for home improvement work. If a contractor seems uncomfortable putting the payment schedule directly into the written contract, that discomfort is answering your question for you.
11. What Does Your Written Proposal Include, Line by Line?
You cannot honestly compare three bids if they describe three different scopes of work, and a single-number quote is not comparable to anything at all. A proper proposal should separately state the number of squares to be installed, tear-off and disposal, decking replacement priced per sheet so there is no renegotiation mid-job, underlayment type, ice barrier coverage and exactly where it stops, which flashing pieces are new and which are being reused, the ventilation plan for both intake and exhaust, starter strip and hip and ridge cap by manufacturer, the warranty tier, cleanup and a magnet sweep of the property, and a start window with an expected duration.
If two bids differ by 30 percent or more, the difference is almost always hiding in those flashing, ventilation, and decking line items, not in the shingles everyone can see.
12. How Will You Ventilate My Attic, and How Did You Decide?
This is the question that tells you the most, and the one homeowners rarely think to ask. Ventilation is the reason two nearly identical roofs on the same street can age at completely different rates. Under IRC R806.2, net free ventilating area must equal 1/150 of the vented attic area, reducible to 1/300 when at least half the ventilation sits in the upper portion of the roof with the balance at the soffits. Inadequate intake at the soffits is the most common defect we find on Rockland County roofs, and it is invisible from the ground, which is exactly why it gets missed so often.
Under-ventilated attics here produce condensation on the underside of the decking in winter, accelerated shingle aging in summer, and ice dams whenever there is snow on the roof, which in Rockland County is most winters. A good contractor will describe both intake and exhaust and will have actually looked in your attic before answering. A contractor who says only that they will add a ridge vent, without mentioning soffit intake in the same breath, has given you half a system. A ridge vent installed without matching intake can make the problem worse, since it starts pulling conditioned air out of the house instead of simply venting the attic.

- Confirm manufacturer certification directly through the manufacturer's own locator tool.
- Ask which building department handles your permit and confirm the fee is in the quote.
- Call at least one reference from the past two years and one from ten years ago.
- Ask for close-up photos of flashing and valleys on a home like yours
- Confirm the company has a real, findable local office
- Get the full payment schedule in writing before any deposit changes hands

Frequently Asked Questions
Do roofing contractors need a license in Rockland County, NY?
Yes. Chapter 286 of the Laws of Rockland County requires a home improvement license from the county’s Office of Consumer Protection for work on private residences of six families or fewer, and roofs are specifically included. Licensed contractors are also prohibited from employing unlicensed subcontractors.
How many licensed home improvement contractors are there in Rockland County?
Rockland County Consumer Protection reports 2,128 active home improvement licenses, alongside 148 electrical and 405 mechanical licenses.
Do I need a permit to replace my roof in Rockland County?
It depends on your town or village. Rockland’s five towns and roughly eighteen villages each operate their own building department, and requirements differ. Ask your contractor which department will issue the permit and confirm the fee is included in the quote. This is different from New Jersey, where most detached single-family reroofs are exempt under state code.
How many estimates should I get?
Three is the standard advice, and it holds up, provided all three describe the same scope of work. Two bids describing identical work are more useful to you than five that do not.
What is the biggest red flag?
A large upfront deposit combined with pressure to sign the same day. Legitimate contractors already have a backlog and do not need your signature this afternoon.
Is the cheapest bid ever the right one?
Sometimes, but check what is missing before assuming it is. In our experience, the gap is usually ice barrier coverage, reused flashing, or an incomplete ventilation plan, and all three cost more to fix later than they saved up front.
