Comprehensive Commercial Roofing Services

Built-Up Roofing

​​Modified bitumen roofing has advanced beyond traditional asphalt methods, utilizing asphalt alongside rubber modifiers, plasticizers, and solvents. Typically, installation uses two methods: hot application, where seams are heated to fuse asphalt for a strong bond, and cold application, which uses adhesives to secure membrane sheets to the substrate and subsequent layers.


BUR (built-up roof) replacement starts with removing the current materials to expose the roof deck, inspecting it for needed repairs. Insulation may be introduced for improved energy efficiency. Fresh bitumen layers and fabrics are applied using either hot asphalt or cold adhesives. Waterproofing is maintained through the application of protective surfacing, flashing, and sealants in commercial roof replacement. An inspection is carried out upon completion to verify adhesion and structural integrity. Continuous maintenance and inspections post-installation are vital for sustained performance.


Layered and reinforced design allows for excellent waterproofing and weather resistance


Strong fire resistance that can be boosted with fire retardant additives

Lifespan of 20 years or more with proper maintenance





Built-up roofing repair involves the initial step of checking for damage such as loose gravel, blisters, or cracks, cleaning the affected region, and applying new bitumen or adhesive as required. Seams and flashings are then checked and repaired to prevent potential leaks. Once repairs are completed, the roof is inspected to verify adhesion and waterproofing effectiveness. Our Freeport commercial roof repair professionals will then suggest ongoing maintenance for prolonged durability.

PVC Roofing

PVC (Polyvinyl Chloride) roofing stands out for its flexibility and excellent reflectivity, effectively blocking up to 90% of UV rays that damage other flat roofing materials. Its resistance to ponding water is achieved through hot-air welding, resulting in a seamless, monolithic installation that enhances seam durability. PVC roofing systems decrease cooling expenses by limiting the heat absorbed by buildings. PVC roofing, endorsed by our commercial roofers, boasts versatility with its range of sizes, thicknesses, designs, and colors suitable for flat and low-slope roofs.


PVC roof replacement begins by removing the existing roof, assessing the deck for repairs, and preparing it accordingly. Then, we move on to the next step of Freeport commercial roof replacement – rolling out the PVC membrane and cutting it to size. Anchoring and securing the sheets is paired with welding the seams to create a waterproof seal, then installing flashings and edge details for leak resistance. The final phase of PVC roofing replacement involves inspecting each detail meticulously to ensure correct installation and secure sealing.

PVC roofing repair requires a strategic approach to maintain the longevity and structural integrity of your roof. At Tri-State Commercial Roofing Corp., an expert commercial roofer will start by thoroughly cleaning the roof to remove dirt, loose materials, and debris, then move on to cutting out damaged sections of the membrane. After cutting a PVC patch that extends beyond the damaged section on all sides, we weld it onto the existing membrane. Before finalizing the PVC roof repair, we’ll complete meticulous inspection and testing processes to ensure precise fusion.

TPO Roofing

TPO (Thermoplastic Polyolefin) is widely employed as a single-ply roofing membrane, recognized for its high solar reflectivity akin 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 makes it well-suited for the temperature fluctuations common in the Freeport region. TPO utilizes hot-air welding for seams and flashings, complemented by algae resistance and environmental sensitivity.


TPO roofing replacement initiates with the removal of the existing roofing material, including old PVC membranes and any compromised insulation layers. We then review and reinforce the roof deck to establish a robust base. Insulation is subsequently inserted 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, creating a seamless, waterproof coating. We weld flashings and edge details to achieve comprehensive coverage and protective measures. Finally, rigorous inspections validate adhesion and seam integrity, ensuring the resilience and longevity of the TPO roof replacement against adverse weather conditions.

Maintains durability through severe weather conditions

Resists impact, tears, and punctures

Superior solar reflectivity absorbs minimal heat and helps cut down on energy costs

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


During TPO roof repair, several essential procedures are followed to enhance its resilience and lifespan. Initially, a thorough inspection identifies any damage such as seam failures, punctures, or tears. Next, the surface is cleaned thoroughly to remove contaminants and dirt. Minor issues are addressed by cutting a PVC patch to the correct dimensions and fusing it to the existing membrane with a hot-air welder. More substantial or intricate repairs may require sections of the membrane to be replaced. Upon completion of the TPO roofing repair, we test the seams to ensure they are resistant to water penetration. Routine maintenance inspections are essential for prolonging the roof’s lifespan and preempting future commercial roof repairs.

Metal Roofing

Fabricated from aluminum or galvalume, metal roofing includes panels that are factory-made or site-formed, accompanied by diverse flashing profiles. It is utilized on both steep-sloped or low-sloped roofs, often selected for its design versatility alongside other roofing types. Metal roofing panels are available in a range of different colors and can be installed on curved roof surfaces. Their longevity ranges from 40 to 70 years, depending on the type of metal and the surface treatment selected.


The process of metal roof replacement begins with the removal of old panels and flashing to inspect the roof deck for potential damage, swiftly resolving any issues uncovered. Upgrading insulation can contribute to enhanced energy efficiency at this stage. New galvalume or aluminum panels are expertly installed, taking into account the roof’s angle and structure. Applying sealants and flashings ensures effective waterproofing. The final step comprises a comprehensive inspection to verify installation quality and compliance with regulations.

The process of metal roof repair initiates with an inspection to identify dents, punctures, or corrosion. Surface preparation follows, which involves cleaning surfaces free of debris, rust, and dirt. Minor problems are addressed using sealants or patches, while significant issues may necessitate panel replacement. Checking and repairing seams and flashings are essential to prevent water damage. Following metal roofing repair, we verify waterproofing efficiency and sealant adhesion. Regular maintenance assists in early issue identification, extending roof longevity, and maintaining 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. Available in black or white, this rubber-like material is ideal for flat and low-slope roofs. Exceptional UV ray protection, wind damage resilience, and fire resistance are key features. Seams between EPDM sheets and flashing components are fused using dedicated adhesives to guarantee a sturdy and resilient bond.


If it’s determined that your current roof is no longer suitable or has sustained irreparable damage, we’ll encourage an EPDM roof replacement. This process includes removing the existing EPDM membrane, preparing the roof substrate, and installing a new one. Our EPDM roofing replacement service delivers continuous protection, dependable functionality, and warranty assurance. To maintain the quality of your EPDM roof, we advocate regular commercial roof maintenance. EPDM roofing is recognized for its cost-effectiveness, reliability, and versatility in commercial settings.
