Comprehensive Commercial Roofing Services

Built-Up Roofing

Derived from traditional asphalt roofing options, modified bitumen roofing incorporates asphalt with plasticizers, rubber modifiers, and solvents. Typically, installation involves two methods: hot application, where seams are heated to meld asphalt for a strong bond, and cold application, employing adhesives to affix the membrane sheets to the substrate and successive layers.


When it comes to built-up roofing repair, the process includes checking for damage such as loose gravel, cracks, or blisters, cleaning the impacted area, and applying new bitumen or adhesive as necessary. Inspection and repair of flashings and seams are also conducted to avoid any leaks. After finishing up with the repairs, a thorough inspection of the roof verifies adhesion and waterproofing. Our Nanuet commercial roof repair specialists will then advise you to schedule regular maintenance to support sustained durability.


Built-up roof replacement involves stripping off the current materials to expose the roof deck, inspecting it thoroughly for any required repairs. Insulation may be introduced for improved energy efficiency. New layers of bitumen and fabrics are then applied using either cold adhesives or hot asphalt. Waterproofing in commercial roof replacement is accomplished through the application of flashings, sealants, and protective surfacing. An inspection is conducted post-installation to validate structural integrity and adhesion. Continuous maintenance and inspections are critical for ensuring sustained performance.

Metal Roofing

Constructed from aluminum or galvalume, metal roofing features panels that are either factory-made or custom-formed, with a diversity of flashing profiles. It is applied to roofs with both low and steep slopes, frequently chosen for its aesthetic compatibility with other roofing materials. Metal roofing panels come in different colors and are ideal for curved roof installations. Their longevity spans from 40 to 70 years, determined by the metal type and surface coating you choose.


For metal roof repair, the process kicks off with a thorough inspection to identify areas affected by corrosion, dents, or punctures. This is followed by surface preparation involving the removal of dirt, rust, and debris. For minor issues, sealants or patches are applied, whereas larger problems may require full panel replacement. Examination and repair of seams and flashings are critical in preventing water damage. Post-repair, we assess sealant adhesion and waterproofing. Consistent maintenance aids in early detection of developing problems, prolongs roof durability, and preserves functionality and aesthetics.


Metal roof replacement begins with removing existing panels and flashing to inspect the roof deck for damage, then repair any problems that are uncovered. Upgraded insulation can be integrated to enhance energy efficiency. Installation of new galvalume or aluminum panels involves precise placement relative to the roof’s pitch and configuration. Applying flashings and sealants is essential for waterproofing purposes. The process concludes with a detailed inspection to verify installation accuracy and compliance with regulations.

EPDM Roofing

EPDM (Ethylene Diene Monomer), also known as rubber roofing, is a favored choice for commercial properties in the northeast. It is available in black or white and is highly adaptable for flat and low-slope roof applications. It provides outstanding protection against harmful UV rays, wind damage, and fire. Seams between EPDM sheets and flashing elements are fused with specific adhesives to create a strong and durable bond.


EPDM roof repair involves straightforward steps, addressing issues like leaks, membrane seam separation, or tears. When starting an EPDM roofing repair, the process begins with visually inspecting the roof or utilizing advanced leak detection methods to identify any issues. Drawing from the expertise of your adept Nanuet commercial roofers, we begin by cleaning affected regions, applying necessary primers, and/or using patches or adhesives on damaged sections. Careful execution of your commercial roof repair is essential to uphold membrane integrity and mitigate future problems.


Should your current roof be deemed inadequate or irreparably damaged, we’ll recommend an EPDM roof replacement. During this process, the existing EPDM membrane is removed, the roof substrate is prepared, and a new one is installed. When you choose our EPDM roofing replacement service, you receive ongoing protection, reliable performance, and warranty support. We recommend regular commercial roof maintenance to preserve the condition of your EPDM roof. EPDM roofing provides a cost-effective, dependable, and adaptable solution for commercial roofs.

PVC Roofing

PVC (Polyvinyl Chloride) roofing features flexibility, high reflectivity, and the ability to block up to 90% of UV rays, circumventing the damage other flat roofing materials are prone to. Its resistance to ponding water is achieved through hot-air welding, creating a seamless, monolithic installation that enhances the roof’s structural integrity. By reducing heat intake, PVC roofing systems lower the cost of cooling buildings. Our commercial roofers recommend PVC roofing for its versatility, with choices in a wide range of designs, colors, thicknesses, and sizes suitable for low-slope and flat roofs.


PVC roofing repair requires careful steps to maintain the endurance and reliability of your roofing structure. 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. We custom-cut a PVC patch that overlaps the damaged area on all sides, then weld it onto the existing membrane. Our inspection and testing protocols ensure the fusion is flawless, thereby completing your PVC roof repair.


PVC roof replacement includes removing the old roof, checking the deck for any repairs, and completing other preliminary tasks. This particular Nanuet commercial roof replacement involves rolling out the PVC membrane and cutting it to the specified dimensions. Sheets are positioned securely, seams welded to create a waterproof seal, and flashings and edge elements are installed to prevent potential leaks. The last step of PVC roofing replacement is to inspect all aspects carefully to ensure proper installation and tight sealing.

TPO Roofing

TPO (Thermoplastic Polyolefin) is commonly used as a single-ply roofing membrane, known for its high solar reflectivity similar to PVC. It offers robust resistance to punctures, impacts, and tears, installed in large sheets typically ranging from 10 to 16 feet wide and up to 100 feet long. Its adaptability makes it ideal for handling the temperature variations typical of the Nanuet area. TPO seams and flashings are fused using hot-air welding. Moreover, the material resists algae and is eco-friendly.


TPO roof repair involves several key steps to ensure durability and longevity. Initially, a thorough inspection is conducted to detect any damage such as seam failures, tears, or punctures. Following this, the surface is cleaned to remove dirt and contaminants. When dealing with minor issues, a PVC patch is cut to size and joined to the existing membrane using a hot-air welder. Larger or more intricate repairs may necessitate replacing parts of the membrane. After the TPO roofing repair has been carried out, we test the seams to confirm their water-tight integrity. Routine maintenance inspections are essential for prolonging the roof’s lifespan and preempting future commercial roof repairs.


During TPO roofing replacement, the initial step involves removing the existing roofing material, which includes aged PVC membranes and any compromised insulation layers. We proceed by inspecting and addressing the roof deck as necessary to furnish a robust base. Next, insulation is installed to enhance energy efficiency. Substantial sheets of fresh PVC membrane are carefully unrolled and positioned. Using hot-air welding, the seams are melded to form a seamless, waterproof surface. We weld flashings and edge details to achieve comprehensive coverage and protective measures. Finally, thorough inspections validate the adhesion and seam integrity, securing the durability and long-term performance of the TPO roof replacement under various weather conditions.
