Comprehensive Commercial Roofing Services

TPO Roofing

TPO (Thermoplastic Polyolefin) is a commonly chosen single-ply roofing membrane, notable for its high solar reflectivity similar to PVC. It boasts excellent resistance to tears, punctures, and impacts, typically installed in sizable sheets ranging from 10 to 16 feet wide and up to 100 feet long. Its flexibility is perfectly suited for the temperature shifts typical of the New Haven area. TPO utilizes hot-air welding for seams and flashings, and it’s also resistant to algae while being environmentally friendly.


Built to last, even in the toughest weather

Hot-air welded seams for a seamless, watertight, leak-resistant, and water-damage-resistant roof

Resists punctures, tears, and impact

Flexibility to withstand temperature fluctuations without cracking

High reflectivity to sunlight for less heat absorption and lower energy expenses


In the first stage of TPO roofing replacement, we eliminate the existing roofing material, comprising worn PVC membranes and damaged insulation layers. We then assess and reinforce the roof deck to ensure a stable foundation. Then, insulation is added to enhance energy efficiency. Large sheets of fresh PVC membrane are rolled out and meticulously placed. Employing hot-air welding, the seams are fused together to create a seamless, water-resistant layer. Next, we weld the flashings and edge details to ensure complete coverage and protection. Finally, we conduct detailed inspections to confirm proper adhesion and seam integrity, ensuring the TPO roof replacement is durable and performs well over time, even in various weather conditions.


TPO roof repair entails several essential stages aimed at ensuring its durability and extended lifespan. Initially, an in-depth inspection pinpoints issues such as punctures, tears, or seam failures. Following this, the surface undergoes thorough cleaning to eliminate contaminants and dirt. For smaller concerns, a PVC patch is cut to size and integrated into the existing membrane through hot-air welding. Larger or more complex repairs could require the replacement of membrane segments. Upon finishing the TPO roofing repair, a test is performed to confirm the seams’ waterproofing. Regular maintenance inspections are necessary to extend the roof’s lifespan and prevent future commercial roof repairs.

PVC Roofing

PVC (Polyvinyl Chloride) roofing is known for its flexibility, exceptional reflectivity, and capability to block up to 90% of UV rays that can deteriorate traditional flat roofing materials. It withstands ponding water with hot-air welding, resulting in a seamless, monolithic installation that strengthens the roof’s seams. PVC roofs contribute to lower cooling expenses by minimizing heat transfer into buildings. Commercial roofers advocate PVC roofing for its versatility, with options available in many designs, colors, thicknesses, and sizes for low-slope and flat roofs.


Highly functional

Aesthetically pleasing

Incredible strength and durability

Perfect for areas with heavy rain and snow

Heat absorption helps cut down on cooling costs

Efficient and reliable

Resistant to wind, fire, and chemicals

Resistant to ponding water


PVC roof replacement begins with removing the current roof, inspecting and repairing the deck as required, and completing other necessary preparations. For this kind of New Haven commercial roof replacement, we roll out the PVC membrane and cut it to the precise dimensions. Securing and positioning the sheets is followed by welding the seams for a waterproof seal, and adding flashings and edge treatments for leak protection. After PVC roofing replacement, a thorough inspection is conducted to validate proper installation and secure sealing.


PVC roofing repair involves many steps that ensure the longevity and integrity of your roofing system. At Tri-State Commercial Roofing Corp., an experienced commercial roofer will begin by cleaning the roof to remove loose materials, debris, and dirt, followed by cutting out damaged sections of the membrane. After cutting a PVC patch to extend beyond the damaged area on all sides, we weld it onto the existing membrane. We meticulously inspect and test to guarantee optimal fusion, which finalizes the PVC roof repair.

Built-Up Roofing

Modified bitumen roofing has progressed beyond standard asphalt methods by incorporating asphalt with rubber modifiers, solvents, and plasticizers. The standard installation process includes two methods: hot application, involving heating seams to fuse the asphalt for a strong bond, and cold application, using adhesives to attach membrane sheets to the substrate and following layers.



Proper care can lead to a 20+-year lifespan

Good fire resistance (which can be further enhanced by fire retardant additives)



Reinforced and layered design allows for outstanding waterproofing and weather resistance



Built-up roof replacement begins with stripping away the current materials to expose the roof deck, followed by a thorough inspection and necessary repairs. Insulation might be included to improve energy efficiency. New bitumen layers and fabrics are then applied using either hot asphalt or cold adhesives. Commercial roof replacement incorporates sealants, protective surfacing, and flashing to maintain waterproofing. An inspection is conducted post-installation to validate structural integrity and adhesion. Ongoing maintenance and inspections after installation are crucial for long-term performance.


When we begin a built-up roofing repair, the process kicks off with examining for problems like cracks, blisters, or loose gravel, cleaning the affected section, and applying new bitumen or adhesive as required. Flashings and seams are meticulously checked and repaired to prevent leakage. After repairs, the roof is inspected for adhesion and waterproofing. Our New Haven commercial roof repair team will then advise on regular maintenance to enhance long-term durability.

Metal Roofing

Made from galvalume or aluminum, metal roofing features factory-made or custom-formed panels, complemented by a variety of flashing designs. It is installed on roofs with varying pitches, often used for its architectural harmony with other roofing systems. Panels for metal roofing are available in a range of colors and can be installed on curved sections of roofs. It boasts a lifespan ranging from 40 to 70 years, contingent upon the metal type and surface coating selected.


Environmentally friendly and fully recyclable

Promotes energy efficiency, reduces cooling expenses, and minimizes heat absorption



Versatile and practical

Exceptionally long lifespan of 40 to 70 years

Low maintenance

High resistance to rot, insects, fire, and mildew


Metal roof replacement begins by removing existing panels and flashing to thoroughly examine the roof deck for damage, promptly repairing any issues detected. Upgrading insulation can contribute to enhanced energy efficiency at this stage. Installation of new galvalume or aluminum panels involves precise placement relative to the roof’s pitch and configuration. For waterproofing, flashings and sealants are meticulously applied. The process concludes with a thorough inspection to ensure installation precision and adherence to guidelines.


Metal roof repair involves an inspection to pinpoint dents, punctures, or corrosion. Surface preparation follows, which involves cleaning surfaces free of debris, rust, and dirt. Minor issues are resolved with patches or sealants, while major repairs may involve the replacement of full panels. Flashings and seams undergo inspection and repair to prevent water damage. Post-repair, we assess sealant adhesion and waterproofing. Regular maintenance detects issues early, prolongs roof life, and maintains both appearance and functionality.

EPDM Roofing

EPDM, or Ethylene Diene Monomer roofing, known colloquially as rubber roofing, is a favored choice for commercial properties across the northeastern region. Offered in white or black, this flexible, rubber-like material is perfectly suited for flat and low-slope roofs. This material offers exceptional resistance to wind damage, fire, and UV rays. EPDM sheet seams and flashing components are bonded securely with specialized adhesives for lasting strength and durability.


Easy installation for commercial roof contractors

Long lifespan


Low maintenance


Should it be found that your existing roof is no longer sufficient or has suffered irreparable damage, we’ll propose an EPDM roof replacement. This involves removing the existing EPDM membrane, preparing the roof substrate, and installing a new one. The EPDM roofing replacement we offer guarantees long-term protection, consistent performance, and warranty support. To maintain the durability of your EPDM roof, we encourage regular commercial roof maintenance. Overall, EPDM roofing offers a cost-effective, reliable, and adaptable solution for commercial roofs.


The process of EPDM roof repair is usually relatively simple, addressing particular issues such as membrane seam separation, leaks, or tears. An EPDM roofing repair begins with a visual inspection of the roof or using advanced leak detection methods to identify and resolve any issues. Based on the findings of your skilled New Haven commercial roofers, we’ll get to work cleaning affected areas, applying primer as needed, and/or applying patches or adhesives to damaged areas. Precise execution of your commercial roof repair is vital to preserve membrane integrity and forestall future complications.
