What you need to know when selecting a commercial roofing services contractor.

If you’re a business owner, property manager, or facility manager in Minnesota, then you know that keeping your building’s roof in good condition is essential to protecting your investment. A leaky roof can cause all sorts of problems, from water damage to mold growth. That’s why it’s crucial to choose a qualified commercial roofing services provider when it’s time for a new roof, routine maintenance, or repair.

In this blog post, we’ll provide an overview of the commercial roofing services process so you’ll know what to expect when you hire a contractor. We’ll also recommend some factors to consider when choosing a provider.

What types of services do commercial roofing contractors provide?

Commercial roofing contractors provide a wide range of services, from installing new roofs to repairing leaks. They can also provide routine maintenance, such as checking for damage and cleaning your roof. Here are some of the most common services offered by commercial roofing contractors:

  • New Roof Installation 
  • Roof Repair 
  • Roof Replacement 
  • Roof Maintenance 
  • Leak Detection 
  • Hail Damage Repair 
  • Storm Damage Repair

Commercial Roof Installation

This is the process of installing a roof for new construction or in situations where the original roof has been removed due to severe damage or building rehabilitation. Commercial roofing contractors work closely with architects to determine the best design and materials to use.

Commercial Roof Replacement

This is the process of replacing an existing roof. It is usually done when a building needs rehabilitation or major repairs, and the existing roof cannot be salvaged. The process of installing a new commercial roof involves removing old materials, repairing the substrate (the surface on which the new roof will be installed), and applying your choice of material to complete the installation. 

Commercial Roof Repair

Leaking commercial roofs require repairs as soon as leaks are discovered. This may involve fixing damage caused by wind, hail, rain, or heavy snowfall. It may include repairing or replacing damaged roof membrane, flashing, and drainage components.

Commercial Roof Maintenance

This is the process of keeping your commercial roof in good condition by performing regular inspections and repairs as needed. It can include cleaning your roof, checking for damage, drainage issues, or leaks, and making necessary repairs. 

A scheduled maintenance program is the best way to detect and resolve issues when they are minor, prolonging the life of your roof and reducing maintenance costs over time.

Leak Detection

Leak detection is the process of finding and repairing leaks in a roof. Finding the source of leaks can be challenging. Professional commercial roofing contractors have the experience necessary to locate even the most obscure leaks.

Hail and Storm Damage Repair

Damage to your commercial roof caused by severe weather such as thunderstorms, hurricanes, tornadoes, and high winds must be repaired promptly. Most commercial roofing services recommend having your roof inspected after severe storms as a preventative measure.

What to consider when choosing a commercial roofing contractor.

When it comes time for a new commercial roof or routine maintenance for an existing one, you’ll need to hire a qualified professional. However, not all contractors are created equal — so how do you know you’re getting the best one for your needs?

Here are some factors you should take into consideration:


Ensure that any contractors you’re considering have plenty of experience with the type of roofing you have or need. You’ll want to choose a company with an excellent reputation in the industry and among other business owners. Referrals or reviews are an excellent place to start.

Insurance and licensing.

All commercial roofing contractors should have liability insurance and be licensed in the state where they’re working. Ask for your business to be added as an “additionally insured” entity on their insurance policy on a ‘certificate of insurance.’ It’s always best to consult an attorney to ensure adequate protection during any major roofing project.


A good contractor will offer a warranty on both their products and services. Make sure you understand what is covered by the warranty and how long it lasts.


Ask the right questions. How quickly can the contractor complete the project? Do they have a backlog of jobs? Will they be working with other subcontractors, and if so, are they qualified and reputable?


How much will the project cost? If you don’t already have an established relationship with a commercial roofing contractor, you’ll want to get estimates from several contractors before making a decision.


Ask the contractor for references from past clients, and check them out to see if the contractor performed quality workmanship.


What type of materials will the contractor be using? Be sure that you’re comfortable with the quality and manufacturer of the products. Are the materials from reputable industry leaders like Elevate (formerly Firestone), GAF, or Johns Manville?


How does the contractor plan to keep your property safe during the project? Will they be using ladders, scaffolding, or heavy equipment? How will they protect your employees, residents, or customers?


What happens when the project is complete? Will the contractor clean up the job site, or will you be responsible for it?

Start a relationship with a commercial roofing services contractor BEFORE you need one.

When choosing a commercial roofing contractor, it’s essential to consider all of these factors to ensure that you’re making the best decision for your business. By taking the time to research and compare contractors, you can rest assured that your new roof will be installed safely and professionally.

Q: How often should I have my commercial roof inspected?

A: Regular roof inspections are essential to ensure the longevity and performance of your commercial roof. Having your commercial roof inspected at least twice a year is recommended, typically in the spring and fall. These inspections help identify any potential issues early on, allowing for prompt repairs and maintenance.

Q: What are the signs that indicate I need commercial roof repairs?

A: Several signs indicate your commercial roof may require repairs. These include water leaks, visible damage such as cracks or holes, loose or missing shingles, sagging areas, and excessive wear and tear. If you notice any of these signs or suspect roof damage, it is advisable to contact a professional roofing contractor for a thorough assessment.

Q: Can I install a new roof over my existing commercial roof?

A: In many cases, installing a new roof over an existing commercial roof is possible. This process, known as a roof overlay or roof recovery, can save time and money compared to a complete roof replacement. However, the feasibility of a roof overlay depends on factors such as the condition of the existing roof, local building codes, and the type of roofing materials being used. Consulting with a professional roofing contractor is crucial to determine if a roof overlay is a viable option for your commercial property.

Q: How long does a commercial roof installation typically take?

A: The duration of a commercial roof installation can vary depending on various factors, such as the size and complexity of the project, the type of roofing system being installed, and weather conditions. On average, a commercial roof installation may take anywhere from a few days to a few weeks. It is best to consult with your roofing contractor to get an accurate estimate based on your specific requirements.

Q: Can I perform any maintenance tasks to prolong the lifespan of my commercial roof?

A: Yes, you can perform several maintenance tasks to help prolong the lifespan of your commercial roof. These include keeping the roof surface clean and free from debris, inspecting and clearing gutters and downspouts regularly, trimming overhanging tree branches, promptly addressing minor repairs, and scheduling professional roof inspections and maintenance as recommended. Following a proactive maintenance routine can help prevent major issues and extend the life of your commercial roof.
