Comprehensive Commercial Roofing Services

Built-Up Roofing

Modified bitumen roofing builds upon traditional asphalt methods by incorporating asphalt with solvents, rubber modifiers, and plasticizers. Installation usually employs two techniques: hot application, where seams are heated to fuse the asphalt for a strong bond, and cold application, using adhesives to attach membrane sheets to the substrate and following layers.


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

Lifespan of 20 years or more with proper maintenance





Layered and reinforced design allows for excellent waterproofing and weather resistance


Built-up roofing repair starts with evaluating for issues such as blisters, loose gravel, or cracks, followed by cleaning the affected area and applying fresh bitumen or adhesive where needed. Seams and flashings are then checked and repaired to prevent potential leaks. After finalizing repairs, the roof undergoes inspection to confirm waterproofing and adhesion. Our Mount Kisco commercial roof repair specialists will then advise you to schedule regular maintenance to support sustained durability.


BUR (built-up roof) replacement includes removing the existing materials to uncover the roof deck, inspecting it thoroughly, and making any necessary repairs. Insulation may be included to enhance energy efficiency. Fresh layers of bitumen and fabrics are applied with cold adhesives or hot asphalt. Sealants, protective surfacing, and flashing are critical for ensuring waterproofing during the commercial roof replacement. Following completion, an inspection ensures structural integrity and adhesion. Regular maintenance and inspections post-installation are imperative for long-term performance.

EPDM Roofing

EPDM (Ethylene Diene Monomer), also known as rubber roofing, is a commonly chosen material for commercial properties in the northeast. The flexible, rubber-like material is available in white or black, and it’s ideal for low-slope and flat roofs. It provides outstanding protection against harmful UV rays, wind damage, and fire. Flashing components and EPDM sheets are joined with specific adhesives to ensure a strong and enduring bond.



Low maintenance

Easy installation for commercial roof contractors

Long lifespan


EPDM roof repair involves straightforward steps, addressing issues like leaks, membrane seam separation, or tears. An EPDM roofing repair starts with visually inspecting the roof or using advanced leak detection methods to pinpoint any problems. Under the guidance of your experienced Mount Kisco commercial roofers, we undertake cleaning affected areas, applying primers as required, and/or applying patches or adhesives to damaged spots. Diligent execution of your commercial roof repair is vital to safeguard membrane integrity and forestall future issues.


If it’s determined that your current roof can no longer adequately serve its purpose or has suffered 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. Our EPDM roofing replacement service guarantees ongoing protection, reliable functionality, and warranty support. Regular commercial roof maintenance is also recommended to sustain the quality of your EPDM roof. EPDM roofing is recognized for its cost-effectiveness, reliability, and versatility for commercial roofing solutions.

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 ability to resist ponding water is strengthened through hot-air welding, creating a seamless, monolithic installation that enhances seam integrity. By reducing heat absorption, PVC roofs effectively decrease cooling expenditures for buildings. Our commercial roofers find PVC roofing to be versatile, offering various thicknesses, sizes, colors, and designs for flat and low-slope roofs.


Resistant to ponding water

Outstanding durability and strength

Aesthetically pleasing

Efficient heat absorption to minimize cooling expenses

Proven to perform well in heavy rain and snow

Highly functional

Resistant to fire, wind, and chemicals

Efficient and reliable


PVC roofing repair requires a strategic approach to maintain 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. After cutting a PVC patch to overlap the damaged area on all sides, we weld it onto the existing membrane. Our detailed inspection and testing procedures confirm proper fusion and complete your PVC roof repair.


In PVC roof replacement projects, our process begins with removing the existing roof, inspecting and repairing the deck as required, and completing necessary preparations. For this Mount Kisco commercial roof replacement task, we roll out the PVC membrane and cut it according to the required dimensions. We position and secure the sheets, weld the seams to create a watertight seal, and install flashings and edge details for leak protection. The last task in PVC roofing replacement is to inspect all elements thoroughly for accurate installation and effective sealing.

Metal Roofing

Metal roofing incorporates panels made from galvalume or aluminum, available in factory-produced or site-formed varieties, and includes diverse flashing profiles. Suitable for low or high-pitched roofs, it is frequently chosen for its aesthetic appeal in tandem with other roofing materials. Metal roofing panels provide a variety of color choices and are suitable for curved roof applications. They boast a lifespan of 40 to 70 years, depending on the metal type and finish utilized.


100% recyclable and environmentally friendly

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


High resistance to fire, mildew, rot, and insects


Practical and versatile

Low maintenance

Exceptionally long lifespan of 40 to 70 years


For metal roof repair, an inspection is conducted to identify punctures, dents, or corrosion. Surfaces are then prepared by cleaning off rust, dirt, and debris. For minor issues, we use sealants or patches, while larger ones might call for the replacement of panels. Flashings and seams are thoroughly inspected and repaired to prevent water damage. Upon completion of metal roofing repair, we confirm sealant adhesion and waterproofing effectiveness. Routine maintenance is key to early issue detection, extending roof lifespan, and maintaining appearance and functionality.


Initiating the metal roof replacement process involves removing existing panels and flashing to inspect the roof deck for damage, promptly addressing any issues identified. Upgrading insulation may further enhance energy efficiency during this process. New galvalume or aluminum panels are expertly installed, taking into account the roof’s angle and structure. Application of sealants and flashings is essential to maintain waterproofing. The final stage involves a thorough inspection to validate installation quality and compliance with standards.

TPO Roofing

TPO (Thermoplastic Polyolefin) is a widely used single-ply roofing membrane, known for its high solar reflectivity similar to PVC. It is highly resistant to punctures, tears, and impacts, installed in large sheets typically 10 to 16 feet wide and up to 100 feet in length. Adapted for the Mount Kisco area’s temperature variations, its flexibility stands out. TPO utilizes hot-air welding for its seams and flashings. Furthermore, it’s resistant to algae growth and environmentally sustainable.


Resists impact, tears, and punctures

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

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

Flexibility to withstand temperature fluctuations without cracking

Built to last, even in the toughest weather


TPO roof repair involves a systematic approach to enhance its durability and lifespan. Initially, a comprehensive inspection is conducted to detect damage such as tears, punctures, or seam failures. Then, the surface is cleaned to remove contaminants and dirt. For smaller issues, a PVC patch is sized accordingly and integrated into the existing membrane through hot-air welding. Larger or more intricate repairs might necessitate the replacement of membrane sections. After completing the TPO roofing repair, we test the seams to ensure they are water-resistant. Continuous maintenance checks are vital for extending the roof’s lifespan and avoiding future commercial roof repairs.


TPO roofing replacement begins with the removal of the current roofing material, encompassing old PVC membranes and damaged insulation layers. We proceed by inspecting and repairing the roof deck to ensure a solid foundation. Next, insulation is installed to enhance energy efficiency. Expansive sheets of new PVC membrane are unrolled and placed with care. By utilizing hot-air welding, the seams are blended to produce a continuous, waterproof barrier. Next, we weld the flashings and edge details to ensure complete coverage and protection. Lastly, thorough inspections validate the adhesion and seam integrity, securing the durability and long-term performance of the TPO roof replacement under various weather conditions.
