Commercial roofs can be one of the most expensive construction components on any building (but also one of the most important since it protects all that is housed within). Although tempting to simply take the low bid, there are other questions you should be asking. Let’s walk through some steps that will show you how to select a commercial roofing contractor.

Who’s Bidding Your Job?

If you put your job out for bid to the masses, you’re going to get lots of bids from both reputable contractors and the “fly-by-nighters.” Consequently, the spread is going to be wider, and comparing apples to apples becomes challenging.
It may serve you well to consider narrowing the number of contractors bidding on your job. You’ll have more control over which contractors are looking at your job, and really, three to four bids are going to give you a fairly accurate idea of your project’s price point.
Also, you want to make sure that the contractor you choose is one with a solid history and is going to be around to back any guarantees or warranties on the roof. Reputation matters…a lot!

What’s Behind the Numbers?

While it’s important to look at the details of each bid to see if they all adhered to the specifications provided (so you can make an accurate comparison), it’s also important to see if any of the contractors provided alternatives.
Known as value engineering, good contractors should ask questions about the specifics of your situation to get a solid understanding of the goals and then provide an alternative bid that may save money or look at a long-term objective they hadn’t thought of before.
For example, perhaps some or all of the insulation can be salvaged, saving significant dollars. Or maybe a completely different roof system would work better for your needs. Don’t always assume that the way the specs are written is the only or even the best way to do the roof.
Note, too, if the contractor includes any value-added components, such as CAD drawings. Pictures say a thousand words and help everyone understand exactly what’s going on.

Are There Any Hidden Costs?

Check to see if the bid addresses unforeseen costs or conditions such as snow removal, replacing damaged decking, or wet insulation. As is often the case, a number that looks too good to be true usually is. Ask why.

Commercial Roofing Contractors: Who’s managing your job?

Have you met with the project manager and/or the team of people who will be managing your job? For a job to go smoothly, there should be one designated project manager who will see it through from start to finish.
Consistency saves money, and you want to be sure that there’s a point person of sorts who will be able to answer any and all questions; oversee quality, and make sure your needs are always met.

Bottom Line?

Be careful. It’s always tempting to take the low bid and run. But be sure to consider all the factors. You’re making a huge investment…and you want it to pay off.

Q: What factors should I consider when selecting a commercial roofing contractor? 

A: Several factors should be considered when selecting a commercial roofing contractor. Look for a contractor with a solid reputation and experience in commercial roofing projects. Check for proper licensing, insurance coverage, and certifications. Request references and reviews from past clients. Additionally, assess their expertise with the specific roofing material you need for your project.

Q: How can I verify the credibility of a commercial roofing contractor? 

A: Verifying the credibility of a commercial roofing contractor is essential. You can start by checking their website for relevant information about their experience, past projects, and client testimonials. Look for online reviews and ratings on platforms like Google and Yelp. Confirm that the contractor holds the necessary licenses and insurance required for your area. You can also ask for references and contact their previous clients to inquire about their experiences.

Q: Should I always choose the lowest bid for a commercial roofing project? 

A: While cost is important, selecting the lowest bid isn’t always the best choice for a commercial roofing project. Extremely low bids might be an indication of subpar materials or workmanship, potentially leading to costly repairs in the future. It’s recommended to consider multiple factors beyond price, including the contractor’s reputation, experience, the quality of materials used, and the scope of services offered. A balance between reasonable pricing and high-quality work is crucial for a successful roofing project.

Q: What role does regular maintenance play in prolonging the life of a commercial roof? 

A: Regular maintenance is essential for extending the lifespan of a commercial roof. Scheduled inspections and maintenance tasks can identify and address minor issues before they escalate into major problems. This proactive approach helps prevent leaks, water damage, and other structural issues. Regular maintenance also ensures that your roofing warranty remains valid. Hiring a professional roofing contractor to perform routine inspections and maintenance can save you money in the long run by avoiding expensive repairs or premature roof replacements.
