If your roof has seen better days, it might be time for a replacement. Waiting until you have massive leaks or a sagging roof is a bad idea—by then, you’re looking at expensive repairs and potential structural damage.
The best move? Start looking for a roofing contractor before you’re in a crisis. But it’s easy to get overwhelmed with all the options. Everyone claims they’re the best, and you’re stuck sifting through endless marketing fluff.
So, how do you find a contractor you can trust? What should you look for? And what red flags should you avoid? Here’s a rundown of what you need to know.
How To Find A Quality Roof Replacement Contractor
Roof replacements are a big investment.
Choosing the wrong contractor leads to unexpected costs and extra repair work that could’ve been avoided. To help you make an informed decision, we’ve put together a guide on how to choose a roofing contractor you can trust.
Search for Authorized Installers From Manufacturers
A great way to find a quality roofing contractor is to check the manufacturer’s website. Many roofing material brands have directories of licensed installers in your area.
This ensures the contractor is trained to install their products correctly. You can even get better warranties. Once you have a list, cross-check reviews and testimonials.
Check Reviews and Testimonials
One of the best places to get testimonials is your neighbors. If you don’t know them, now’s the best time to get friendly. Drive around, look for work being done, and ask for referrals.
For online reviews, here’s where you have to be careful. There are many ways to fake reviews, even on sites like Google or Yelp. If you’re looking at reviews online, look out for:
- Generic and over-the-top reviews: It’s a red flag if most reviews include comments like “Best roofer ever! Amazing fast service! Highly recommended!”
- All 5-Star Reviews with No Negatives: Nobody’s perfect. However, mixed ratings with reasonable responses to negative reviews can indicate authenticity.
- Multiple reviews with a similar style: Compare the wording from the reviews. If several mention the same oddly specific detail, that’s a red flag.
You should also look for reviews with photos, like before-and-after shots. These images can tell you a lot about how they operate, the quality of work, and the cleanliness of the worksite.
Look Through The Contractor’s Work Portfolio
Trustworthy roof replacement contractors should proudly showcase their work—there’s no reason to hide it. So, always take time to review their portfolio.
This ensures they have experience with full roof replacements, not just minor repairs. In addition to their website, you can also find completed projects on their social media pages or Google.
Another tip is to look for photos of similar roof replacements to ensure they’ve worked with your type of roofing material or roof design.
But, if a contractor has little to show or only uses stock images, that’s a red flag.
Visit Local Suppliers
Local supply stores, such as lumber yards, construction supply stores, or wholesale roofing distributors, often work directly with contractors.
The employees of these stores may have a couple of contractors they can refer. Established roofers tend to have long-term relationships with suppliers.
You can ask which contractors buy high-quality materials. Knowing the cost of these materials also lets you avoid getting markups on materials when you ask for estimates.
Ask the Homeowners Association
Talk to the Homeowners Association (HOA) if you live in a neighborhood with one. HOAs can have strict guidelines about roofing materials, colors, styles, and aesthetics.
Some HOAs have pre-approved or recommended roofing contractors that meet their standards. These contractors will likely understand all the rules and the required administrative work.
Roof Replacement Contractor Red Flags
When you plan to replace your roof, getting multiple quotes from contractors is important. But before committing to one, ensure that they don’t have the following red flags:
Asking For Down Payment for Roof Replacement Quotes
Estimates and quotes help homeowners understand the scope and pricing of their roof replacement. All reputable roofing contractors would give both for free.
Most would also provide a free roof inspection for a more accurate quote. If a roofer asks for payments for the estimates, then that’s a sign of a red flag.
Contractors Pressuring You to Sign a Contract
Stay away from contractors that hit you with sentences like, “If you sign today. . .” These are obvious examples of high-pressure salesman tactics.
Even the best contractors need time to check a roof to provide a detailed estimate. They’ll also want to give enough time for you to review your options.
Roofers Hiding Subcontracting
Subcontracting itself isn’t a red flag—many reputable roofing companies bring in specialists for specific tasks. The problem is when a contractor hides it from you.
If they don’t tell you who’s actually doing the work, they might be cutting costs by hiring unvetted, low-quality labor. So, always ask if the crew works directly and is insured.
Misconceptions About Hiring a Roofing Contractor
There are many general misconceptions about roof replacements and contractors, especially regarding price, quality, and what to expect during the process. The most common include:
The Cheapest Roofer Won’t Provide Quality Work
Contrary to popular belief, picking the cheapest roofers on your list is not a bad idea as long as they can provide proof of quality work or they don’t have negative reviews.
One reason roofers can charge less than competitors is low overhead. They could also have leftover materials from a bigger project.
Longer Warranties Equal a Better Roof
Many homeowners assume that an extended warranty means a high-quality roof, but that’s not always true. Some contractors offer extended warranties as a selling point.
However, if the roof is poorly installed, that warranty may not cover installation issues. Identifying a bad roofing job early before leaks or structural problems appear is far more important than relying on an extended warranty.
A New Roof Doesn’t Need Maintenance
Just because you’ve had your roof replaced doesn’t mean you can ignore upkeep. Your roof can take a beating, but minor damages can creep up fast and cause underlying issues.
Insurance companies can also reject roof claims due to neglect. If that happens, you’ll be left to shoulder the entire roof replacement.
Replacing Your Roof Can Be Stressful
Finding the right roof replacement contractor helps get peace of mind knowing that it’ll stand the test of time. To recap, here’s how you can find high-quality roof replacement contractors:
- Search manufacturing websites and see if they have authorized installers in your area
- Check reviews and testimonials online and in your local community
- Look through contractor portfolios and ensure the quality of work
- Visit local suppliers and ask if they can refer a quality roofer
- Ask HOAs if they have a pre-approved or recommended list of roofers
