When your roof needs attention, the contractor you hire can make the difference between a lasting solution and a costly mistake. ASI Construction has worked with homeowners across the western suburbs of Chicago since 2013, and in that time, one truth has remained constant: an informed homeowner makes better hiring decisions. Choosing the right roofing contractor is not simply about finding the lowest price. It requires evaluating qualifications, transparency, and local expertise. The roofing industry includes contractors of widely varying skill levels, and without the right questions, it can be difficult to tell them apart. Whether you are dealing with storm damage, an aging roof, or a full replacement, this guide will walk you through the essential questions to ask before signing any contract. Taking the time to vet your options thoroughly is one of the most valuable steps you can take to protect your home and your investment.
1. Is the Contractor Licensed and Insured?
Licensing and insurance are non-negotiable when hiring a roofing contractor. A licensed roofing contractor has met the regulatory requirements set by the state of Illinois, demonstrating a baseline level of professional competency. Without adequate insurance, you could be held financially responsible for injuries that occur on your property or for any damage caused to your home during the work. Always ask for proof of both general liability insurance and workers’ compensation coverage. Verify that the policy is current and that coverage amounts are adequate for a project of your scope. Request the name of the insurance provider and call to confirm the policy is active before work begins. Contractors who hesitate to provide this documentation should be disqualified immediately. No legitimate roofing company will take issue with a homeowner asking for verification.
2. What Contractor Qualifications and Certifications Do They Hold?
3. How Many Roofing Estimates Should You Get?
Industry guidance consistently points to getting at least three roofing estimates before making a hiring decision. Multiple estimates give you a realistic picture of fair market pricing in your area and reveal how different contractors approach the scope of work. If one estimate is significantly lower than the others, that is worth investigating. It may reflect lower-quality materials, an incomplete scope of work, or a contractor cutting corners on labor. When comparing estimates, look beyond the final number and evaluate what each proposal actually includes. Collecting multiple bids is not about finding the cheapest option. It is about understanding the full picture so you can make a confident, well-informed decision.
4. What Should Be Included in a Roofing Estimate?
A thorough roofing estimate should outline the full scope of work in writing. This includes the materials to be used, specific product names and grades, labor costs, project timeline, disposal of old materials, and permit fees if applicable. A reputable contractor will also specify how they plan to protect your landscaping, siding, and windows during the project. Vague estimates that list only “roofing materials” and “labor” without further detail are a warning sign. The more specific the estimate, the more confidence you can have that the contractor understands the full scope of your project and has priced it accordingly. If anything in the estimate is unclear, ask for clarification in writing before you proceed.
What a Strong Roofing Estimate Includes vs. What a Weak One Leaves Out
| Estimate Component | Strong Estimate | Weak Estimate |
| Materials | Specific product name, grade, and manufacturer listed | Listed only as “roofing materials” |
| Labor | Broken out separately with detail |
Bundled into a single total |
| Project Timeline | Start date and estimated completion date included | No timeline provided |
| Tear-Off and Disposal | Explicitly included with method noted | Not mentioned |
| Permit Fees | Itemized or noted as included | Not addressed |
|
Property Protection |
States how landscaping and siding will be protected | No mention |
| Warranty Information | Manufacturer and workmanship warranty both specified | No warranty detail |
|
Payment Schedule |
Deposit amount and final payment terms defined | Full payment requested upfront |
This table can be used as a checklist when reviewing bids. Any estimate that is missing several of these components warrants a follow-up conversation with the contractor before you move forward.
5. How Can You Verify Roofing Company Reviews?
Online reviews are a useful starting point, but they require critical evaluation. Look for reviews on multiple platforms, including Google and the Better Business Bureau. Pay attention to how the company responds to negative feedback. A contractor who engages professionally with criticism demonstrates accountability. Look for patterns across reviews rather than focusing on individual outliers. A company with dozens of consistently positive reviews over several years carries more weight than one with a handful of recent five-star ratings. You can also ask the contractor for references from recent projects in your area. Speaking directly with past customers gives you insight that no review platform can fully capture, particularly around communication, timeline adherence, and post-project follow-through.
6. Is the Contractor Local?
Hiring a local roofing contractor offers practical advantages that national companies cannot replicate. A contractor based in your region understands local building codes, weather patterns, and HOA requirements that affect material selection and installation methods. They also have an established reputation in the community, which creates a meaningful incentive to deliver quality work. Storm-chasing contractors who appear after major weather events and operate outside your area often lack this accountability. Once the job is done, they move on and can be difficult to reach if issues arise. When you hire a roofer in Oakbrook Terrace or the surrounding suburbs, a local contractor with deep community ties is almost always the more reliable and accessible choice over the long term.
7. What Warranties Are Offered?
A quality roofing project should come with two distinct types of warranties. The first is a manufacturer’s warranty on the materials themselves, which covers defects in the product. The second is a workmanship warranty provided by the contractor, which covers installation errors. These two warranties work together, and gaps in either can leave you unprotected. Contractor certifications often determine the length and scope of manufacturer warranties available to you. For example, Owens Corning Platinum Preferred Contractors can offer extended warranty coverage not available through standard installers. Ask specifically what each warranty covers, how long it lasts, and what actions or circumstances would void it. Get all warranty terms in writing before the project begins.
8. How Long Will the Project Take?
A realistic timeline is a sign of professional planning. For a standard residential roof replacement, most projects are completed within one to three days, depending on the size of the home, weather conditions, and material availability. Larger or more complex projects may require additional time, and that is reasonable as long as the contractor communicates clearly. A contractor who promises an unusually fast turnaround without explanation may be planning to cut corners. Conversely, excessive delays without proactive communication can indicate poor scheduling or resource management. Ask for a written project timeline and confirm how the contractor will notify you if delays arise. Clear expectations at the outset protect both parties and reduce the chance of disputes mid-project.
9. What Red Flags Should You Watch For?
Several warning signs indicate that a contractor may not be trustworthy. Beware of any contractor who demands full payment up front, as reputable companies typically require a reasonable deposit with the balance due upon completion. Pressure tactics, such as urgency about limited availability or expiring discounts, are designed to prevent you from doing your due diligence. Lack of a physical business address, no verifiable reviews, reluctance to provide a written contract, and unmarked vehicles are additional reasons for concern. Be wary of contractors who show up unsolicited after a major storm, offering deeply discounted work. A legitimate licensed roofing contractor will welcome your questions, provide straightforward answers, and never rush you into signing.
10. Do They Offer Free Roof Inspections?
A free roof inspection is a low-risk way to establish whether your roof actually needs work and to evaluate a contractor’s professionalism firsthand. It gives you an opportunity to observe how thoroughly they assess your property and how clearly they communicate their findings. A quality inspector will document what they find and walk you through the results without pressure. ASI Construction offers free roof inspections to homeowners throughout the western suburbs of Chicago. Whether your concern is storm damage, aging shingles, or a suspected leak, a no-cost inspection provides the information you need to make an informed decision without any financial commitment upfront. It is also a natural opportunity to assess whether the contractor is someone you want working on your home.
Making the Right Choice for Your Roofing Project
Choosing the right roofing contractor comes down to doing your research before committing. Verify licensing and insurance, review credentials, gather multiple estimates, and check references across more than one platform. Prioritize contractors with established local reputations, transparent and detailed contracts, and clear warranty offerings from both the manufacturer and the installer. The questions in this guide are not formalities. They are practical filters that separate qualified professionals from contractors who may leave you with a bigger problem than you started with. The time you invest in vetting your options will pay dividends in the form of a well-executed project and lasting protection for your home.
