Comprehensive Commercial Roofing Services

PVC Roofing

PVC (Polyvinyl Chloride) roofing stands out for its flexibility, exceptional reflectivity, and ability to block up to 90% of UV rays that can degrade alternative flat roofing materials. It is engineered to endure ponding water using hot-air welding techniques, resulting in a seamless, monolithic installation that reinforces the roof’s structural integrity. PVC roofs also reduce heat absorption into buildings, effectively lowering cooling expenses. 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 roof replacement involves starting with the removal of the existing roof, inspecting and repairing the deck as needed, and completing other preparatory tasks. In the process of Morristown commercial roof replacement, we roll out the PVC membrane and trim it to fit precisely. The sheets are carefully positioned and anchored, seams welded tightly to ensure waterproofing, and flashings and edge details installed to prevent leaks. The last step of PVC roofing replacement is to inspect all aspects carefully to ensure proper installation and tight sealing.


When it comes to PVC roofing repair, maintaining the longevity and structural integrity of your roof is essential. At Tri-State Commercial Roofing Corp., a dedicated commercial roofer will start by cleaning the roof to remove dirt, debris, and loose materials, and then proceed to remove damaged sections of the membrane. We cut a patch that extends beyond the damaged area on all sides and weld it to the existing membrane. Inspections and testing follow to ensure the fusion meets our high standards and to finalize your PVC roof repair.

Metal Roofing

Fabricated from galvalume or aluminum, metal roofing is made from panels that are either manufactured in factories or custom-formed on-site, featuring various flashing profiles. It is installed on roofs of different slopes, often selected for its ability to complement other roofing materials and architectural features. Metal roofing panels offer a range of colors and can be fitted onto curved roof sections. Their durability ranges from 40 to 70 years, contingent on the type of metal and the surface treatment selected.


Metal roof replacement starts with dismantling old panels and flashing to assess the roof deck for potential damage, addressing any issues promptly. Upgraded insulation can be integrated for improved energy efficiency. New aluminum or galvalume panels are installed securely, considering the roof’s slope and architectural configuration. Application of sealants and flashings is essential to maintain waterproofing. A comprehensive inspection concludes the process to ensure installation standards and code adherence.


Addressing metal roof repair starts with a comprehensive inspection to detect dents, signs of corrosion, or punctures. Surfaces are then prepared by cleaning off rust, debris, and dirt. Minor problems are addressed using sealants or patches, while significant issues may necessitate panel replacement. Thorough inspection and repair of seams and flashings are crucial in preventing water damage. After completing metal roofing repair, we verify sealant adhesion and waterproofing effectiveness. Routine maintenance is crucial for early issue identification, extending roof lifespan, and maintaining appearance and functionality.

Built-Up Roofing

Modified bitumen roofing is a departure from traditional asphalt roofing. It incorporates asphalt with plasticizers, rubber modifiers, and solvents. Installation usually employs two techniques: hot application, where seams are heated to fuse the asphalt for a strong bond, and cold application, utilizing adhesives to adhere membrane sheets to the substrate and subsequent layers.


BUR (built-up roof) replacement starts with removing the current materials to uncover the roof deck, followed by inspecting it and making any needed repairs. Insulation may be installed to enhance energy efficiency. New layers of bitumen and fabrics are applied using hot asphalt or cold adhesives. Protective surfacing, flashing, and sealants are utilized to ensure waterproofing during commercial roof replacement. Following completion, an inspection ensures structural integrity and adhesion. Regular maintenance and inspections post-installation are essential to uphold long-term performance.


Built-up roofing repair begins with assessing for concerns such as loose gravel, cracks, or blisters, cleaning the impacted section, and applying additional bitumen or adhesive as needed. Seams and flashings undergo inspection and repair to prevent any potential leaks. After repairs are complete, the roof is inspected to confirm waterproofing and adhesion. Our Morristown commercial roof repair professionals will then suggest ongoing maintenance to ensure long-lasting durability.

EPDM Roofing

Rubber roofing, scientifically known as EPDM (Ethylene Propylene Diene Monomer), is extensively used in commercial buildings across the northeast. The flexible, rubber-like material is available in white or black, and it’s ideal for low-slope and flat roofs. The material offers superior resistance to UV radiation, fire, and wind damage. Flashing and EPDM sheets are securely bonded with specific adhesives for maximum durability.


If it’s determined that your current roof is no longer suitable or has been damaged beyond repair, we’ll recommend 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 ensures ongoing security, dependable functionality, and warranty coverage. We recommend regular commercial roof maintenance to preserve the integrity of your EPDM roof. All in all, EPDM roofing stands out as a cost-effective, reliable, and versatile option for commercial applications.


EPDM roof repair procedures are typically straightforward, targeting issues such as leaks, membrane seam separation, or tears. When initiating an EPDM roofing repair, we start with a visual inspection of the roof or utilizing advanced leak detection techniques to pinpoint any issues. Guided by your skilled Morristown commercial roofers, our approach begins with cleaning affected sections, applying essential primers, and/or utilizing patches or adhesives as required. Diligent execution of your commercial roof repair is vital to safeguard membrane integrity and forestall future issues.

TPO Roofing

TPO (Thermoplastic Polyolefin) is widely utilized as a single-ply roofing membrane, notable for its high solar reflectivity similar to PVC. It boasts excellent resistance to impacts, tears, and punctures, with installation typically involving large sheets ranging from 10 to 16 feet wide and up to 100 feet long. Designed for the temperature changes in Morristown, its flexibility is key. TPO utilizes hot-air welding for its seams and flashings, ensuring algae resistance and environmental sustainability.


The initial phase of TPO roofing replacement involves the extraction of the existing roofing material, which includes outdated PVC membranes and any deteriorated insulation layers. We subsequently evaluate and repair the roof deck to provide a sturdy foundation. Next, insulation is applied to boost energy conservation. Extensive sections of new PVC membrane are carefully rolled out and positioned. Employing hot-air welding, the seams are fused together to create a seamless, water-resistant layer. Flashings and edge details are also welded for comprehensive coverage and protection. Finally, detailed inspections confirm the adhesion and seam integrity, ensuring the resilience and long-lasting effectiveness of the TPO roof replacement against varying weather conditions.


In TPO roof repair, specific steps are taken to bolster its longevity and resilience. Initially, a thorough inspection identifies any damage such as seam failure, tears, or punctures. Subsequently, the surface is cleansed to eradicate contaminants and dirt. When addressing smaller issues, a PVC patch is sized appropriately and fused onto the existing membrane using a hot-air welder. More extensive or complicated repairs might involve replacing sections of the membrane. After completing the TPO roofing repair, a critical step is testing the seams to ensure they are watertight. Regular maintenance inspections are essential for extending the roof’s life and preempting future commercial roof repairs.
