How to Hire a Roofing Contractor Without Getting Burned
How to hire a roofing contractor is one of the most important questions a homeowner can ask before a major project, and most people do not ask it until they are already in trouble. A bad contractor does not always announce itself upfront. The low bid looks appealing. The quick timeline sounds convenient. By the time the problems show up, the crew is gone and the warranty is worthless.
This guide walks through exactly what to look for, what questions to ask, and what to watch out for before you sign anything.
Treat It Like Hiring an Employee
The right mindset going into a contractor search matters. You are not doing the contractor a favor by calling them. You are the one writing the check, and that means you are in charge of the process. Ask hard questions. Request documentation. If a contractor gets defensive when you ask for proof of insurance or photos of past work, that is your answer right there.
A good contractor expects scrutiny. They have the paperwork ready, they can point you to finished projects, and they welcome the conversation because they know they can back it up.
Step 1: Check Licensing and Insurance Before Anything Else
This is not optional. A roofing contractor working in Michigan needs to be licensed and insured, full stop. There are two types of insurance that matter here.
General liability insurance protects you if the contractor damages your home or property during the project. Workers’ compensation insurance protects you if someone on the crew gets hurt on your roof. If a contractor does not carry both, you are taking on serious financial risk the moment they set foot on your property.
Ask for proof of both policies before the conversation goes any further. A legitimate contractor will hand them over without hesitation.
Step 2: Look at Their Past Work
You would not hire a photographer without seeing their portfolio. The same logic applies here. Ask for photos of completed roofing projects and, if possible, references from past customers in your area.
Pay attention to how long the company has been operating. A newer company with no track record is a bigger gamble than one that has been completing projects in the area for years. Experience in Michigan specifically matters because local contractors understand the weather patterns, the common roofing failures in the region, and the products that hold up long term in this climate.
Step 3: Understand the Difference Between an Estimate and a Proposal
These two words get used interchangeably but they are not the same thing, and the difference affects how you compare bids.
An estimate is a general ballpark figure. It gives you a rough idea of cost but the details are thin and the number can shift. A proposal is more specific. It should include the products being used, the brand and line of shingles, the scope of work, and a breakdown of what is included. When you are comparing bids from multiple contractors, you need to be looking at proposals, not estimates. Otherwise you are comparing apples to very different apples.
Step 4: Know What Is Actually Going on the Roof
A price without product details is not a real bid. Ask the contractor exactly what shingle they are proposing, which manufacturer, which product line, and what the warranty covers. There is a significant difference between a builder-grade shingle and a product like the CertainTeed Landmark PRO. Both might be described as architectural shingles in a vague estimate, but they are not the same product and they do not perform the same way.
Ask whether they are installing a complete manufacturer system. Most warranties are only valid when the roofing system, including underlayment, ventilation, and flashing, meets the manufacturer’s installation requirements. A contractor who skips required components to lower the bid may be handing you a voided warranty before the job is even finished.
Step 5: Ask Whether They Use Consistent Crews
Most roofing companies in metro Detroit use subcontracted crews, and there is nothing wrong with that. It is standard practice in this industry and does not reflect on the quality of the finished product. Most crews worth hiring prefer to be 1099, which makes the subs. What does matter is whether the contractor works with the same crews consistently.
A contractor who has built long-term relationships with a stable group of installers knows exactly what they are going to get on every job. Those crews understand the contractor’s standards, they have worked through the details together on dozens of projects, and the relationship is built on a track record of results.
A contractor who pulls from a rotating pool of unfamiliar crews is a different story. When the people on your roof are strangers to the person who sold you the job, nobody can really predict the outcome. Quality control becomes guesswork, accountability gets murky, and the homeowner is the one left holding the result.
Ask your contractor how long they have been working with their crews and whether they use the same ones across their jobs. A confident, honest answer to that question tells you a lot about how the company actually operates.
Step 6: Do Not Let Price Be the Only Factor
The lowest bid is not always the best deal. In roofing especially, low bids usually mean something is being left out, whether that is ventilation, ice and water shield in vulnerable areas, or the labor time required to do the flashing correctly around skylights, chimneys, and valleys.
Get at least three proposals and compare them line by line. If one bid is significantly lower than the others, ask the contractor to walk you through exactly what they are including and why their number is different. A legitimate contractor will be able to explain it. If they cannot, or if the answer is vague, move on.
Step 7: Get Everything in Writing
Before any work starts, you should have a signed contract that covers the scope of work, the products being installed, the project timeline, the payment schedule, and what happens if something goes wrong. A verbal agreement is not protection. A contract is.
Be cautious about contractors who ask for a large upfront payment before work begins. A reasonable deposit is standard, but a contractor asking for the majority of the project cost before a single shingle comes off the truck is a red flag.
What to Look for in a Roofing Contractor in Metro Detroit
Oakland County, Wayne County, and Macomb County homeowners deal with real roofing conditions. Cold winters, ice dams, spring wind events, and aging housing stock all create specific demands that a competent local contractor should be able to speak to directly.
When you talk to a contractor in this area, they should know what ice and water shield is, where it needs to go, and why it matters in a Michigan winter. They should understand attic ventilation (in detail) and how poor ventilation shortens the life of a roof from the inside out. If a contractor cannot explain these things in plain language, they are not the right fit.
