At GMT Home Services, we’re more than a commercial roofing company—we’re partners committed to protecting your business. From new roof installations to roof replacements and expert repairs, our team helps extend the life of your existing roof while ensuring performance, durability, and long-term benefits.
Installing a new roof on your business isn’t just about materials and labor — it’s about protecting everything inside your building, from your employees to your equipment. At GMT Home Services, we don’t just put on a roof; we make sure your property has a system that can handle Connecticut’s weather, keep your energy costs manageable, and give you confidence that your building is safe. Whether it’s low slope roof systems, TPO roofing membranes, metal roofing, asphalt shingles, or liquid applied roof coatings, we install with care, precision, and a deep understanding that your roof is the first line of defense for your business.
We know that even small roof problems can cause big stress. A tiny leak can damage inventory, interrupt operations, or even put your staff at risk if left unchecked. That’s why our commercial roof repair services are designed to respond quickly and effectively. From leaks and standing water to cracks in roofing membranes, storm damage, or damaged insulation, we fix issues before they spiral into costly disasters. Our team treats every repair as urgent because we understand your business can’t afford downtime.
Deciding to replace your roof is never easy — it usually comes after years of patching repairs and worrying about “what if it leaks again.” At GMT Home Services, we approach commercial roof replacement with honesty and care, helping you choose the best roofing system for your property. A new roof means more than protection; it restores peace of mind, boosts energy efficiency, and reduces long-term maintenance costs. When your roof has reached the end of its life, we’re here to make the transition as seamless as possible, so you can focus on running your business.
Owning a commercial building means always thinking ahead — and your roof should be no exception. Regular roof maintenance and inspections save you money and stress in the long run. Our team provides preventative inspections, gutter and downspout cleaning, and ongoing monitoring for signs of leaks, cracks, or deterioration. We also offer roof restoration options like coatings that extend your roof’s life without the cost of full replacement. Think of it as protecting your investment before problems become emergencies.

Choosing the right roofing system for your business isn’t just about price — it’s about making sure your building can handle Connecticut’s weather year after year. At GMT Home Services, we help you understand your options so you can feel confident that your roof will protect your property, lower energy costs, and last for the long haul.
Here are the commercial roofing systems we most often install, repair, and maintain:
Each roofing system is carefully selected based on your building’s needs, from drainage and insulation to overall performance. Our goal is to give you a solution that reduces headaches, lowers costs, and provides reliable protection for years to come.
Low-slope roofs on retail centres, schools, and warehouses are prone to pooling water, which can weaken roofing membranes and lead to leaks. Drainage improvements and flat roof repairs usually range from $500–$2,500.

Most roof problems don’t start with a sudden disaster — they start small. Maybe you’ve noticed a stain on the ceiling after a storm, or your energy bills keep climbing even though nothing inside has changed. These are your roof’s way of quietly asking for attention. Addressing issues early not only protects your building but also prevents costly downtime for your business.
Here are the most common signs that it’s time to consider commercial roof repair:
The truth is, roofing problems don’t fix themselves. A quick inspection today can save you from major repairs or even a full replacement tomorrow.
When industrial facilities, hospitals, or shopping centres notice rising energy bills, leaks, or cracks, it may be time for roof replacement. In Connecticut, full commercial roof replacements average $6–$12 per sq. ft., depending on materials and complexity.

We know that replacing or repairing a commercial roof can feel overwhelming. That’s why our process is built around clarity, trust, and minimal disruption to your business. From the first inspection to the final warranty, we walk you through every step so you’re never left guessing.
Here’s how we make sure your roof gets the care it deserves:
At every stage, our priority is protecting your business, your employees, and your investment. You’ll always know what’s happening, why it matters, and how we’re ensuring your roof’s performance long into the future.
After severe weather, businesses like restaurants, hotels, and office buildings often face leaks from torn membranes or damaged flashing. Emergency commercial roof repairs typically cost $350–$1,200, depending on the extent of damage.

Companies like Tecta America and Centimark are recognized among the largest commercial roofing contractors in the United States.
Commercial roofing refers to specialized roofing systems designed for commercial applications, including flat roofs, metal roofing, TPO membranes, and roof coatings.
TPO roofing membranes are among the most common commercial roofing materials due to their durability, energy efficiency, and cost-effectiveness for low slope roofs.
The average cost of a commercial roof in the U.S. falls between $100,000 and $200,000 for mid-size buildings, though smaller projects may cost less.
Commercial roofs are often low slope or flat, requiring specialized membranes and coatings, while residential roofs are typically pitched and use materials like asphalt shingles.
In most cases, yes—if the leak results from sudden damage such as storms, debris, or fire. However, insurance usually doesn’t cover leaks caused by wear and tear or lack of maintenance.
On average, roof leak repairs cost $350–$1,200, depending on the roof system, materials, and extent of damage. A professional inspection ensures accurate pricing and long-lasting results.
EXCELLENT Based on 356 reviews Posted on Daniel JacobTrustindex verifies that the original source of the review is Google. GMT Chimney Services did an outstanding job installing a new liner in my chimney. Their price was nearly half of what other companies quoted, and the work was excellent. My chimney wasn’t drafting correctly, which caused my water heater to break. After the liner was installed, the issue was completely resolved. Highly recommend for their fantastic work!Posted on Gary SandersonTrustindex verifies that the original source of the review is Google. Outstanding service with Joe he was very helpful and I would recommend gmt and JoePosted on Kevin HealyTrustindex verifies that the original source of the review is Google. We had Joe work on a gas fireplace in our new home. He was prompt, polite, and a pleasure to deal with. I would absolutely use this company again and felt he went above and beyond to assist usPosted on josh aTrustindex verifies that the original source of the review is Google. 3.5 stars Not the worst not the best experience.. the guys that came and did inspection were great and knowledgeable, the guys that came and did the liner were also great.. Juan that came to check out my fireplace and put on the caps was excellent.. the guys that came and did the pointing, and outside work did ok work but didnt communicate with us... never rang doorbells or gave us calls, not good communication.... this comapny expect you to be home almost at all times says they will work with you in times so, scheduled a day to come work and needed someone to be home wife took day off and they tried to tell us no one was home didn't even knock or ring door bell... just left tried to tell us no one was home and that they rang door bell and knocked.. we have cameras and ring door bell and wife took day off.. one week goes by no calls nothing gave us 30 min notice called abut 9a.m to show up around 930... again the workers were all pretty good but the communication between them the lady in the office and home owners should be better.. she Called and asked for payment job wasn't complete.. caps were not install.. Juan came out again was great did what he had to do and bill was paid.. I'd love to use them again for a cleaning because the work was ok and some of the guys doing the work. But they need to realize that people work for a living and cant be home at all times and some of the workers and the office need to be able to communicate with the home owners and possibly each other a bit better.. the pricing was average better then some others and work was overall ok.. if your someone that can be home often this company will be perfect for youPosted on MariaTrustindex verifies that the original source of the review is Google.

Nice workPosted on Ravi GopieTrustindex verifies that the original source of the review is Google. Joe came to check my fireplace since I wanted to make sure I was good for the season before lighting it. He did a wonderful job of explaining that the fireplace was safe to use this year and advised me of when to contact them for a cleaning. He checked the firebox, and explained what was happening in the flue. I will certainly be calling GMT again for my future cleanings because of this interaction. Joe was friendly and warm, and did a great job explaining how to use the fireplace.Posted on אילן חרוביTrustindex verifies that the original source of the review is Google. Great service!
