It is always better to proactively maintain the health of your commercial roofing system, rather than waiting for leaks to occur.

Cost & Energy-Efficient Solutions for Your Commercial Building

There is a wide variety of materials and installation techniques to choose from when planning your roof for your commercial building. Adding to the confusion are the different acronyms used to describe various roofing types: SPF, TPO, EPDM, etc. If you want to make sure you’ve got the right type of commercial roofing, you’ve come to the right place. Harmony Home Improvement will help you select a roofing or re-roofing treatment that suits your building and your budget.


Hiring a contractor for a commercial roofing project is a big decision that requires careful consideration. Building owners want to make sure that they choose the right contractor who can deliver the project successfully and within budget. In this process, there are several key factors that building owners take into account before making a final decision. From experience and expertise to reputation and reliability, the following factors usually determine who is ultimately hired for a commercial roofing replacement job:

Experience and expertise: Building owners look for contractors who have a proven track record of successful commercial roofing projects and who have the necessary expertise to handle the job. We have been doing commercial roof replacements across Connecticut for over 20 years.

Quality of work: The quality of work is a major consideration, as building owners want to ensure that the roofing project is done correctly the first time and that the roof will last for many years. Our GAF Master Elite, TAMKO Pro, and CertainTeed Shingle Master certifications make us stand out from the crowd.

Price: Building owners often compare quotes from different contractors to find the best value for their investment. We always offer our best price first. You'll never experience haggling with us.

Reputation and reliability: Building owners want to work with contractors who have a good reputation in the industry, are reliable, and have a history of delivering projects on time and within budget. Our Google reviews speak for themselves! 

Safety and liability: Building owners also consider the safety and liability aspects of the project. They want to work with contractors who have a strong commitment to safety and who are insured and bonded to protect against any accidents or damages that may occur during the project. Safety is our number one priority on every job.


Commercial roofing is sometimes described by the type of roof on the building: flat, low-slope, shed and steep-slope, for example. In other cases, roofing is described by the installation technique – such as “built-up roofing,” “standing-seam roofing,” “single-membrane roofing” and “torch-down roofing.” More frequently, roofing is described simply by the material that’s being installed. Here are some of the types of commercial roofing we expertly install:

  • Metal roofing includes factory-made panels and flashing profiles, as well as roofing panels that are cut and formed at the building site. When installed on a sloped roof, metal roofing offers the benefits of energy efficiency (lower heat gain during warm, sunny weather) and low maintenance.
  • SPF (Spray Polyurethane Foam) roofing is a popular roofing option for flat and low-slope roofs. Applied with spray equipment, an SPF roof provides a seamless roof covering that can go over an existing roof or over new construction. SPF roofing is popular because it eliminates the need for most types of roof flashing and it also functions as roof insulation, lowering the building’s heating and cooling costs.
  • EPDM roofing is sometimes referred to as “rubber roofing” because this roofing membrane material (technically known as ethylene propylene diene monomer) is black and flexible like a rubber inner tube. EPDM roofing can be installed on flat and low-slope roofs. Seams between adjacent EPDM sheets and metal flashing elements are typically sealed with special adhesive.
  • TPO Asphalt shingle roofing (Thermoplastic Polyolefin) roofing is a single-membrane system, just like EPDM roofing. Installed in large rolls, TPO can be installed with mechanical fasteners or by fusing seams with heat. The white TPO material used most often does a good job of reflecting solar radiation, which helps to reduce the demand for air conditioning in hot weather.
  • Modified bitumen roofing is applied in rolls that are usually heated with a torch to seal seams and adhere the asphaltic material to the substrate and to flashing details. The popularity of more modern single-membrane systems (EPDM & TPO) has reduced the demand for modified bitumen roofing.
  • Asphalt shingle roofing will always be popular. Plenty of commercial buildings with sloped roofs depend on asphalt shingles for weather protection. Asphalt roofs are among the most affordable, and gives building owners many shingle styles and colors to choose from.

Just had Harmony replace my entire roof as well as three skylights. From the quoting process through delivery of material and install the process was smooth and most importantly to me the communication was clear. The crew was timely, friendly and left my yard in great shape. Can’t recommend them enough and actually I’m talking with them now about my gutters!

Andrew Fritsch

We hired Harmony to re-side our house. Dennis was professional and knowledgeable during the quoting process. They were in the same price range as two other companies we had quote the project, but were slightly lower in cost. We ended up choosing Harmony because we felt most comfortable with Dennis. The siding team showed up on time every day and only needed 3 1/2 days to complete the project. The house looks great and there were absolutely no issues throughout the entire project. We would highly recommend Harmony and will use them again for future projects at our home.

Kyle Raczkowski

We recently hired Harmony to replace our roof and install vinyl siding and new gutters. Our experience with Harmony was exceptional. The quality of work was top-notch. Dennis kept us informed of every aspect of the job. He was always available (24×7) to answer questions and continually stopped on-site throughout the job to inspect progress and ensure we were satisfied. Most importantly he is honest and caring; a quality sometimes absence in the home improvement business. I am happy to recommend Harmony Home Improvement.

Jim Peterson

Overall, very pleased with how everything went and I really appreciated Dennis’ no BS approach to things. Some of my windows are showing their age and I will most likely be giving Harmony a call again when the time comes to tackle that project. If you’re in to hiking at all, ask Dennis about his adventures in the White Mountains!

Ross Pieper

Could not recommend Harmony highly enough! I recently had recurring wind damage to my roof (installed by a different contractor), which ultimately required a complete roof replacement. Harmony stood out from the first conversation. Dennis was extremely responsive, prompt, worked up a thorough and competitive proposal, and literally went out of his way to assist with the insurance claim. Perhaps most importantly, however, it was the overall customer experience – their attention to detail, low-pressure approach, and competence and professionalism – that left you feeling like they were more concerned about servicing the customer than just getting another sale.
