Comprehensive Commercial Roofing Services

EPDM Roofing

Rubber roofing, scientifically known as EPDM (Ethylene Propylene Diene Monomer), is a preferred roofing material for commercial properties in the northeast. Offered in black or white, they are well-suited for low-slope and flat roofs. This material offers exceptional UV ray protection, wind damage defense, and fire resistance. Seams between flashing elements and EPDM sheets are sealed using precise adhesives for a robust and durable bond.



Easy installation for commercial roof contractors

Long lifespan

Low maintenance


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 process includes removing the existing EPDM membrane, preparing the roof substrate, and installing a new one. Opt for our EPDM roofing replacement service for continued protection, dependable performance, and warranty coverage. We also advocate for regular commercial roof maintenance to uphold the quality of your EPDM roof. EPDM roofing offers a cost-effective, dependable, and adaptable option for commercial roofs.


EPDM roof repair is a straightforward process that typically targets specific issues like leaks, tears, or membrane seam separation. The initiation of an EPDM roofing repair involves visually inspecting the roof or employing advanced leak detection methods to uncover any potential problems. Leveraging the expertise of your capable Yonkers commercial roofers, our process involves cleaning affected areas, applying requisite primers, and/or implementing patches or adhesives where necessary. Thorough execution of your commercial roof repair is essential to uphold membrane integrity and mitigate future challenges.

TPO Roofing

TPO (Thermoplastic Polyolefin) is a popular single-ply roofing membrane, renowned for its solar reflectivity akin to PVC. It demonstrates robust resistance to impacts, punctures, and tears, installed in wide sheets typically ranging from 10 to 16 feet in width and up to 100 feet in length. It’s crafted to handle Yonkers’s temperature changes with ease, thanks to its flexibility. TPO uses hot-air welding for its seams and flashings, boasting algae resistance and environmental friendliness.


Excellent solar reflectivity reduces energy costs and minimizes heat absorption

Resistant to tears, punctures, and impact

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

Flexible enough to endure temperature changes without cracking

Incredible durability that withstands harsh weather conditions


In the first stage of TPO roofing replacement, we eliminate the existing roofing material, comprising worn PVC membranes and damaged insulation layers. We then assess and mend the roof deck as necessary to ensure a sturdy foundation. Insulation is then added to improve energy efficiency. Extensive sections of new PVC membrane are carefully rolled out and positioned. Through hot-air welding, the seams are melded together, resulting in a seamless, water-resistant finish. Flashings and edge details undergo welding to provide thorough coverage and protective measures. Lastly, meticulous inspections are performed to verify adhesive strength and seam integrity, guaranteeing durability and longevity in the new TPO roof replacement.


TPO roof repair includes several essential steps to enhance its durability and longevity. Initially, a detailed inspection identifies issues such as seam failures, punctures, or tears. Following this, the surface is cleaned to remove dirt and contaminants. Minor issues are handled by cutting a PVC patch to size and attaching it to the current membrane with a hot-air welder. Larger or more complicated repairs might involve substituting segments of the membrane. Upon finishing the TPO roofing repair, we proceed to test the seams for their water-tight seal. Routine maintenance inspections can extend the roof’s lifespan and preempt future commercial roof repairs.

Built-Up Roofing

Modified bitumen roofing is an advancement over conventional asphalt roofing techniques. It blends asphalt with plasticizers, solvents, and rubber modifiers. Typically, installation uses two methods: hot application, where seams are heated to fuse asphalt for a strong bond, and cold application, employing adhesives to attach membrane sheets to the substrate and following layers.


Layered and reinforced design allows for excellent waterproofing and weather resistance


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

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





The BUR (built-up roof) replacement process starts by removing the existing materials to reveal the roof deck, followed by inspecting and repairing it as needed. Insulation might be introduced to enhance energy efficiency. New layers of bitumen and fabrics are applied using hot asphalt or cold adhesives. Waterproofing is guaranteed through the application of flashings, protective surfacing, and sealants in the commercial roof replacement procedure. An inspection is conducted after completion to confirm structural integrity and adhesion. Regular maintenance and inspections post-installation are necessary for sustained performance.


When we begin a built-up roofing repair, the process begins with examining for problems like cracks, blisters, or loose gravel, cleaning the impacted section, and applying additional bitumen or adhesive as needed. Inspection and repair of flashings and seams are also carried out to ensure no leaks occur. Following repairs, a comprehensive roof inspection assesses waterproofing and adhesion. Our Yonkers commercial roof repair crew will also recommend regular maintenance for prolonged durability.

PVC Roofing

PVC (Polyvinyl Chloride) roofing is flexible, highly reflective, and capable of blocking up to 90% of UV rays that can degrade other flat roofing materials. It withstands ponding water using hot-air welding, resulting in a seamless, monolithic installation that reinforces the roof’s seam strength. By reducing heat absorption, PVC roofs effectively decrease cooling expenditures for buildings. PVC roofing is considered by our commercial roofers to be versatile, offering a range of designs, colors, thicknesses, and sizes for low-slope and flat roofs.


Proven to perform well in heavy rain and snow

Resistant to fire, wind, and chemicals

Resistant to ponding water

Highly functional

Aesthetically pleasing

Reliable and efficient

Exceptional strength and durability

Absorbs heat, leading to reduced cooling expenses


For PVC roof replacement, the process starts with removing the existing roof, assessing the deck for repairs, and conducting other necessary preparations. For this kind of Yonkers commercial roof replacement, we roll out the PVC membrane and cut it to the precise dimensions. Sheets are securely positioned and anchored, seams welded to achieve waterproofing, and flashings and edge features installed to prevent leaks. The final step in PVC roofing replacement is a detailed inspection to guarantee proper installation and sealing.


When it comes to PVC roofing repair, ensuring the durability and integrity of your roof is paramount. At Tri-State Commercial Roofing Corp., an experienced commercial roofer will initiate the process by cleaning the roof to eliminate dirt, loose materials, and debris, then proceed to cut out damaged sections of the membrane. A custom-cut PVC patch, extending beyond the damaged area on all edges, will be welded securely onto the current membrane. PVC roof repair is finalized through inspection and testing procedures to confirm the quality of fusion.

Metal Roofing

Made from galvalume or aluminum, metal roofing features factory-made or custom-formed panels, complemented by a variety of flashing designs. Suitable for low or high-pitched roofs, it is frequently chosen for its aesthetic appeal in tandem with other roofing materials. Metal roofing panels offer a selection of colors and are suitable for installation on curved roof sections. They have a lifespan of 40 to 70 years, determined by the metal type and surface finish.




Sustainable and 100% recyclable

Practical and versatile

High resistance to mildew, rot, insects, and fire

Low maintenance

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

Exceptionally long lifespan of 40 to 70 years


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 may also be part of the plan for increased energy efficiency. Installing new galvalume or aluminum panels involves precise placement in relation to the roof’s incline and design. For waterproofing efficiency, flashings and sealants are meticulously applied. The process ends with a comprehensive inspection to ensure installation precision and adherence to standards.


In the course of metal roof repair, a thorough inspection is conducted to locate signs of corrosion, punctures, or dents. This is followed by surface preparation, which includes cleaning away rust, debris, and dirt. For minor problems, patches or sealants are applied, whereas major issues may require panel replacement. Seams and flashings are inspected and repaired to prevent water damage. Upon completion of metal roofing repair, we confirm sealant adhesion and waterproofing effectiveness. Regular maintenance helps detect issues early, prolongs roof life, and preserves functionality and appearance.
