5 Questions to Ask Your Flat Roof Contractor
When it comes to repairing or replacing a flat roof, hiring the right contractor is critical. Flat roofing requires specialized knowledge, the right materials, and precise installation methods. Unfortunately, not all contractors are up to the task. At Big Apple Renovators, we’ve seen too many homeowners in New York left with leaks, fire hazards, or voided warranties because they didn’t know what to ask before signing the dotted line.
Whether your roof is starting to show signs of wear or you're already dealing with water damage, here are five things to ask a potential contractor about, to ensure they are up to the job.
1. What is Your Experience with Flat Roofing?
Flat roofs aren’t one-size-fits-all, and treating them like they are is a recipe for disaster. Unlike pitched roofs, flat roofs require specialized knowledge, materials, and installation techniques. The wrong choice here can lead to serious issues like water ponding, chronic leaks, insulation failure, or even fire hazards, especially if incompatible materials are used in hot applications.
Before you commit, ask the contractor if they specialize in flat roofing systems, or if it’s just one of many services they offer. Some contractors may claim to "do it all," but that doesn’t mean they’re equipped to handle the unique demands of a flat roof. You need someone who works with flat roofs every day, not someone applying sloped-roof logic to a totally different system.
A true flat roofing expert will take the time to assess your property and explain the best options for your specific needs. That includes walking you through the pros and cons of hot-applied versus cold-applied systems, the importance of proper drainage and ventilation, and what materials (like modified bitumen, TPO, or EPDM) make the most sense based on your building type and budget.
At Big Apple Renovators, flat roofs are our specialty, and we know that no two are alike. We design and install every system with long-term performance, safety, and warranty protection in mind.
2. Are Your Crews In-House?
One of the biggest red flags when hiring a flat roofing contractor is subcontracted labor. Many companies farm out their work to third-party crews, which means you often have no idea who’s actually showing up at your home, or how well they’ve been trained. That lack of control can lead to rushed jobs, miscommunication, and corners being cut. Worst of all, it can void your manufacturer warranty if the installation doesn't meet exact specifications.
That’s why it’s important to ask whether the company uses in-house crews or relies on subcontractors. Our team takes a different approach. We only use skilled, in-house crews, professionals we know, trust, and train ourselves. These are experienced roofing specialists who are not just familiar with flat roof systems, but experts in them. Because they work directly under our supervision, we’re able to maintain strict quality standards, adhere to all manufacturer guidelines, and ensure every single project is done right the first time.
3. Do You Offer Warranties and Document Your Projects?
Even the best materials can fail if they’re installed incorrectly, and without labor coverage, you could be stuck footing the bill for someone else’s mistake. When speaking with your contractor, be sure to ask, “What warranties do you offer for both materials and labor, and how long do they last?” Look for contractors who provide at least 20 years of coverage on both fronts.
For example, we offer 50-year material warranties and 25-year labor warranties on shingles, and 20-year protection on flat roofing systems. That’s the kind of long-term security homeowners deserve.
But the protection shouldn’t end there. Reputable contractors also document the entire project, from the first inspection to the final walkthrough. This includes progress photos, detailed repair notes, and completion checklists that can be essential for insurance claims, warranty activation, or even when it’s time to sell your home. A paper trail proves the work was done right, and it helps you avoid costly headaches down the road.
4. Do You Ensure Permit and Code Compliance?
In New York, roofing work must meet strict local building codes. If your contractor skips the permit process or cuts corners on compliance, you could face fines, delays, or even be forced to redo the work. Worse yet, improperly permitted jobs can become a serious issue during a home sale or insurance claim.
That’s why it’s crucial to work with a contractor who understands the ins and outs of city permitting and code requirements. Big Apple Renovators handle all permitting and inspections in-house, so your project stays legal, safe, and fully up to code.
5. How Will You Communicate With Me Along the Way?
You shouldn’t be left guessing when your contractor will show up, or what they’re doing once they’re there. From the first consultation to the final walkthrough, great contractors keep you in the loop. That means giving you a heads-up before arrival, updating you if there are delays, and having a dedicated point of contact on the job site every day. Roofing work can be disruptive, especially in tight-knit New York neighborhoods, so proactive communication with you and your neighbors is part of doing the job right.
Be sure to ask your contractor, “How will you keep me updated throughout the project, and who will be my main point of contact?” Clear communication can make all the difference in a smooth, stress-free roofing experience.
