Comprehensive Commercial Roofing Services

Metal Roofing

Fabricated from galvalume or aluminum, metal roofing is made from panels that are either manufactured in factories or custom-formed on-site, featuring various flashing profiles. It is installed on roofs with varying slopes, frequently chosen for its aesthetic appeal in conjunction with other roofing systems. With a variety of color choices, metal roofing panels are versatile enough for installation on curved roof sections. They boast a lifespan of 40 to 70 years, depending on the metal type and finish utilized.


For metal roof repair, an inspection is conducted to identify punctures, dents, or corrosion. Surface preparation follows, involving the removal of dirt, debris, and rust. Patches or sealants are applied for minor issues, with the potential for panel replacement in more severe cases. Examination and repair of flashings and seams are pivotal in preventing water damage. After completing metal roofing repair, we verify sealant adhesion and waterproofing effectiveness. Consistent maintenance aids in early issue detection, prolongs roof service life, and upholds appearance and functionality.

Low maintenance

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

Exceptionally long lifespan of 40 to 70 years



Beginning metal roof replacement involves dismantling old flashing and panels to meticulously check the roof deck for damage, promptly addressing any issues. Insulation may be upgraded at this point for energy efficiency. Installing new galvalume or aluminum panels involves precise placement in relation to the roof’s incline and design. For waterproofing, flashings and sealants are meticulously applied. The final stage involves a thorough inspection to validate installation quality and compliance with standards.

TPO Roofing

TPO (Thermoplastic Polyolefin) is a prevalent single-ply roofing membrane, celebrated for its high solar reflectivity comparable to PVC. It exhibits strong resistance to tears, impacts, and punctures, with installation typically in sheets ranging from 10 to 16 feet wide and up to 100 feet long. Adapted for the Brewster area’s temperature variations, its flexibility stands out. TPO uses hot-air welding for its seams and flashings, and it’s resistant to algae while being environmentally sound.


TPO roof repair entails several essential stages aimed at ensuring its durability and extended lifespan. Initially, a comprehensive inspection is conducted to detect damage such as tears, punctures, or seam failures. Afterward, the surface is meticulously cleaned to eliminate contaminants and dirt. Smaller concerns are resolved by cutting a PVC patch to the appropriate size and attaching it to the existing membrane using a hot-air welder. Larger or intricate repairs might involve replacing portions of the membrane. After the TPO roofing repair is done, the seams are tested for watertightness. Routine maintenance inspections can extend the roof’s lifespan and preempt future commercial roof repairs.

Maintains flexibility under varying temperatures to prevent cracks


TPO roofing replacement begins with the removal of the current roofing material, encompassing old PVC membranes and damaged insulation layers. Following this, we meticulously inspect and repair the roof deck as needed to establish a solid base. Next, insulation is applied to boost energy conservation. Large panels of fresh PVC membrane are rolled out and meticulously positioned. Through hot-air welding, the seams are melded together, resulting in a seamless, water-resistant finish. We weld flashings and edge details to ensure complete coverage and protective measures. Lastly, meticulous inspections validate adhesion and seam integrity, ensuring durability and longevity in the new TPO roof replacement.

Built-Up Roofing

Developed from classic asphalt roofing practices, modified bitumen roofing integrates asphalt with rubber modifiers, solvents, and plasticizers. Installation typically uses two approaches: hot application, which entails heating seams to fuse asphalt for a strong bond, and cold application, which uses adhesives to attach membrane sheets to the substrate and subsequent layers.


Built-up roofing repair begins with examining for issues like blisters, loose gravel, or cracks, then cleaning the affected area and applying additional bitumen or adhesive as needed. Seams and flashings undergo inspection and repair to prevent any potential leaks. Following the completion of repairs, the roof is inspected to ensure proper adhesion and waterproofing. Our Brewster commercial roof repair crew will then advise you to schedule regular maintenance to promote long-lasting durability.

Layered and reinforced design provides outstanding weather resistance and waterproofing


Lifespan of 20 years or more with proper maintenance



BUR (built-up roof) replacement involves removing the existing materials to expose the roof deck, inspecting it thoroughly for any required repairs. Insulation might be introduced for improved energy efficiency. New bitumen layers and fabrics are then applied using either hot asphalt or cold adhesives. Ensuring waterproofing in commercial roof replacement involves the application of flashings, sealants, and protective surfacing. An inspection is performed at the conclusion of the process to validate structural integrity and adhesion. Post-installation maintenance and inspections are essential for maintaining long-term performance.

PVC Roofing

PVC (Polyvinyl Chloride) roofing is flexible and highly reflective, effectively blocking up to 90% of UV rays that can damage other types of flat roofing materials. Its resistance to ponding water is achieved through hot-air welding, creating a seamless, monolithic installation that enhances the roof’s structural integrity. PVC roofing lowers cooling costs by preventing buildings from absorbing too much heat. Our commercial roofers regard PVC roofing as a versatile choice, offering an array of designs, sizes, thicknesses, and colors suitable for low-slope and flat roofs.


When it comes to PVC roofing repair, maintaining the longevity and structural integrity of your roof is essential. At Tri-State Commercial Roofing Corp., an experienced commercial roofer will begin by cleaning the roof to eliminate debris, dirt, and loose materials, then proceed to cut out damaged sections of the membrane. We will prepare a PVC patch that overlaps the damaged section on all sides, welding it securely to the current membrane. Your PVC roof repair will be completed after we inspect and test to ensure proper fusing.


Highly functional

Incredible strength and durability

Aesthetically pleasing

Resistant to ponding water

Helps reduce cooling costs by absorbing heat

The process of PVC roof replacement projects starts with removing the current roof, inspecting the deck, making necessary repairs, and completing other preparatory tasks. Next, we continue with the Brewster commercial roof replacement by rolling out the PVC membrane and cutting it to the required dimensions. Sheets are positioned securely, seams welded to create a waterproof seal, and flashings and edge elements are installed to prevent potential leaks. The final step in PVC roofing replacement is a detailed inspection to guarantee proper installation and sealing.

EPDM Roofing

Rubber roofs, also known as EPDM (Ethylene Propylene Diene Monomer) roofing, are widely chosen for commercial properties in the northeast due to their flexibility and durability. Available in black or white, this rubber-like material is ideal for flat and low-slope roofs. This material provides exceptional wind resilience, protection against UV rays, and fire resistance. EPDM sheets and flashing elements are fused together with specialized adhesives for a durable and secure bond.


EPDM roof repair involves straightforward procedures, addressing issues such as leaks, tears, or membrane seam separation. To begin an EPDM roofing repair, the process includes visually examining the roof or employing advanced leak detection methods to identify potential issues. Leveraging the expertise of your capable Brewster commercial roofers, our process involves cleaning impacted areas, applying requisite primers, and/or implementing patches or adhesives where necessary. Diligent execution of your commercial roof repair is crucial to safeguard membrane integrity and avert future issues.

Should we find that your current roof is no longer able to meet your needs or has sustained irreparable damage, we’ll suggest an EPDM roof replacement. This includes removing the existing EPDM membrane, preparing the roof substrate, and installing a new one. When you opt for our EPDM roofing replacement service, you receive ongoing protection, reliable performance, and warranty backing. Maintaining the condition of your EPDM roof through regular commercial roof maintenance is crucial. EPDM roofing provides a cost-effective, dependable, and adaptable solution for commercial roofs.
