Comprehensive Commercial Roofing Services

Metal Roofing

Designed with panels made from aluminum or galvalume, metal roofing includes factory-made or site-formed components and incorporates a selection of flashing profiles. It finds application on both steep-sloped or low-sloped roofs, often serving as a distinctive architectural feature in conjunction with other roofing solutions. Panels of metal roofing feature diverse color options and are suitable for installation on curved roof segments. Metal roofing boasts an impressive lifespan of 40 to 70 years, depending on the metal type and surface finish chosen.


When undertaking metal roof repair, the process starts with an examination to locate dents, punctures, or signs of corrosion. Afterward, surfaces are prepared by cleaning off dirt, debris, and rust. For minor issues, sealants or patches are applied, whereas larger problems may require full panel replacement. Inspection and repair of flashings and seams are crucial to prevent water damage. Post-repair, we verify waterproofing effectiveness and sealant adhesion. Regular maintenance helps detect issues early, prolongs roof life, and preserves functionality and appearance.


Versatile and practical

Minimizes heat absorption, reduces cooling costs, and contributes to energy efficiency


100% recyclable and environmentally friendly

Exceptionally long lifespan of 40 to 70 years


Low maintenance

Highly resistant to rot, fire, insects, 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. Upgraded insulation may be included to enhance energy efficiency. Installation of new galvalume or aluminum panels requires careful positioning relative to the roof’s slant and layout. Application of sealants and flashings ensures effective waterproofing. The final step involves a rigorous inspection to verify installation precision and compliance with regulations.

PVC Roofing

Featuring flexibility and high reflectivity, PVC (Polyvinyl Chloride) roofing effectively blocks up to 90% of UV rays, protecting against the degradation that other flat roofing materials are subject to. Its ability to endure ponding water is ensured through hot-air welding, creating a seamless, monolithic installation that enhances seam integrity. Decreasing heat absorption into buildings, PVC roofs effectively slash cooling expenses. In the opinion of our commercial roofers, PVC roofing stands out for its versatility, with options in many sizes, thicknesses, colors, and designs for flat and low-slope roofs.


PVC roofing repair requires systematic steps to preserve the longevity and structural integrity of your roof. Your dedicated commercial roofer at Tri-State Commercial Roofing Corp. will first clean the roof to eliminate loose materials, dirt, and debris, and then proceed to cut out damaged sections of the membrane. We cut a PVC patch that extends beyond the damaged area on all sides and weld it onto the existing membrane. To finalize your PVC roof repair, we’ll perform thorough inspections and testing to ensure effective fusion.


Outstanding durability and strength

Resistant to ponding water

Efficient and reliable

Heat absorption helps cut down on cooling costs

Perfect for areas with heavy rain and snow

Highly functional


PVC roof replacement begins by removing the existing roof, inspecting the deck for repairs, and completing other preparatory measures. For this Hempstead commercial roof replacement task, we roll out the PVC membrane and cut it according to the required dimensions. Securing the sheets in place is followed by welding the seams tightly to achieve a watertight seal, then adding flashings and edge details for leak prevention. At the end of PVC roofing replacement, a thorough inspection ensures precise installation and adequate sealing.

EPDM Roofing

Rubber roofing, scientifically known as EPDM (Ethylene Propylene Diene Monomer), is a popular roofing choice for commercial properties in the northeast. It is available in black or white and is particularly suitable for low-slope and flat roofs. It excels in resisting harmful UV rays, fire, and wind damage. Flashing and EPDM sheets are securely bonded with specific adhesives for maximum durability.


EPDM roof repair involves a simple process, focusing on issues such as tears, membrane seam separation, or leaks. The process of EPDM roofing repair begins with a thorough visual assessment of the roof or employing advanced leak detection methods to identify potential problems. Drawing from the expertise of your adept Hempstead commercial roofers, we begin by cleaning affected regions, applying necessary primers, and/or using patches or adhesives on damaged sections. Precision is paramount in executing your commercial roof repair to uphold membrane integrity and forestall potential complications.

Low maintenance


If your current roof is determined to be inadequate or damaged beyond repair, we’ll recommend an EPDM roof replacement. This process involves removing the existing EPDM membrane, preparing the roof substrate, and installing a new one. Opting for our EPDM roofing replacement service ensures ongoing protection, reliable functionality, and warranty assurance. Regular commercial roof maintenance is also recommended to sustain the quality of your EPDM roof. EPDM roofing stands out as a cost-effective, reliable, and versatile solution for your commercial roofing needs.

Built-Up Roofing

Modified bitumen roofing is a departure from traditional asphalt roofing. It consists of asphalt combined with rubber modifiers, plasticizers, and solvents. Typically, installation employs two techniques: hot application, which entails heating seams to fuse asphalt for a durable bond, and cold application, using adhesives to attach membrane sheets to the substrate and subsequent layers.


Built-up roofing repair involves inspecting for damage like cracks, blisters, or loose gravel, cleaning the affected region, and applying new bitumen or adhesive as required. Seams and flashings are meticulously inspected and repaired to prevent any leaks. After finalizing repairs, the roof undergoes inspection to confirm waterproofing and adhesion. Our Hempstead commercial roof repair team will then recommend routine maintenance for sustained durability.



Regular maintenance can lead to a lifespan of 20 years or more

Reinforced and layered design allows for outstanding waterproofing and weather resistance



Good fire resistance with the option to include fire retardant additives for greater protection



BUR (built-up roof) replacement involves removing the existing materials to expose the roof deck, inspecting it thoroughly for any required repairs. Insulation may be added for energy efficiency. New layers of bitumen and fabrics are then applied with hot asphalt or cold adhesives. Utilizing sealants, protective surfacing, and flashing ensures waterproofing during commercial roof replacement. Following completion, an inspection is conducted to verify structural integrity and adhesion. Consistent maintenance and regular inspections are essential for maintaining long-term performance.

TPO Roofing

TPO (Thermoplastic Polyolefin) is a popular choice for single-ply roofing membranes, known for its high solar reflectivity comparable to PVC. It offers robust durability against impacts, tears, and punctures, installed in large sheets typically sized 10 to 16 feet wide and up to 100 feet in length. Designed for Hempstead’s temperature fluctuations, its flexibility is its hallmark. TPO utilizes hot-air welding for its seams and flashings, ensuring algae resistance and environmental sustainability.


TPO roof repair requires several essential procedures to ensure its durability and extended life. First, a thorough inspection identifies damage such as punctures, seam failures, or tears. Next, the surface is cleaned to remove dirt and contaminants. In cases of minor problems, a PVC patch is tailored and integrated into the existing membrane using a hot-air welder. Extensive or complicated repairs may involve replacing parts of the membrane. Following the TPO roofing repair, testing is conducted to ensure the seams are effectively waterproofed. Regular maintenance inspections help extend the roof’s life and prevent future commercial roof repairs.


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

Durable enough to endure extreme weather conditions

Resists impact, tears, and punctures

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

Adaptability to temperature fluctuations prevents the formation of cracks


To begin TPO roofing replacement, we remove the current roofing material, including aged PVC membranes and damaged insulation layers. We subsequently inspect and address the roof deck as necessary to furnish a robust base. Afterward, insulation is incorporated for improved energy effectiveness. Sizable sheets of new PVC membrane are rolled out and positioned with precision. Using hot-air welding, the seams are melded to form a seamless, waterproof surface. We weld flashings and edge details to ensure complete coverage and safeguarding. 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.
