Roofing Systems

Single-ply roofing systems are popular for commercial properties due to their affordability, ease of installation, and durability. We specialize in installing three types of single-ply membranes.

  • EPDM: Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber roofing membrane perfect for flat or low-sloped commercial roofs. It is highly resistant to UV rays, ozone, and weathering, making it an ideal choice for locations with extreme weather conditions.
  • TPO: Thermoplastic Polyolefin (TPO) roofing systems are made from rubber and plastic polymers. They offer excellent resistance against tears, punctures, and chemical damage, making them a popular choice for high-traffic areas.
  • PVC: Polyvinyl Chloride (PVC) roofing membranes are highly reflective and energy-efficient, making them an excellent option for commercial properties to reduce energy costs. They are also resistant to fire, chemicals, and strong winds.

Built-Up Roofing (BUR)

Built-up roofing (BUR) systems have been around for over a century, making them one of the oldest roofing systems used for commercial properties. This type of roof consists of multiple layers of asphalt and ply sheets, making it highly durable and long-lasting.

Asphalt, Metal, Wood, and Slate Shingles Roofing

Various roofing systems are becoming increasingly popular due to their longevity, energy efficiency, and aesthetic appeal. We specialize in installing various types of materials, including:

  • Asphalt Shingles: Asphalt shingles are one of commercial buildings’ most common and affordable roofing options. They come in various colors and styles and can last up to 30 years.
  • Metal Shingles: Metal shingles mimic the appearance of traditional roofing materials such as slate, wood, or tile. They offer excellent durability and low maintenance. Corrugated metal roofs are made from corrugated sheets of galvanized steel or aluminum. They are lightweight, easy to install, and highly durable.
  • Modified Bitumen: This roofing system is made from modified asphalt and can provide excellent waterproofing for flat or low-sloped roofs.
  • Standing Seam Metal: Standing seam metal roofs have vertical seams that interlock to create a watertight seal. They offer excellent resistance against leaks and are highly durable.
  • Wood Roofing: Wood shingles or shakes provide a natural and rustic look to any building. They are also durable and can last for decades if properly maintained.

Attachment Methods

In addition to the type of roof, there are other factors to consider when choosing a commercial roofing system. These include attachment methods: how the roofing system is fastened to the building’s structure.

There are several standard attachment methods used in commercial roofing. These include:

  • Mechanical Attachment: This method involves securing the roofing material using mechanical fasteners, such as screws or nails. The materials are attached directly to the building’s structure, providing a secure and durable option for commercial roofs.
  • Induction welded: The roofing material is heated and fused to the building’s structure using an induction welding tool. This creates a strong bond between the roof and the building, ensuring stability and longevity.
  • Ballast Attachment: Instead of adhering or fastening the roofing material directly to the building’s structure, ballast attachment involves using heavy materials, such as gravel or pavers, to hold the material in place. This method is commonly used for single-ply roofing systems.
  • Fully Adhered Attachment: Similar to adhesive attachment, this method involves bonding the entire underside of the roofing material to the substrate using adhesives. This provides a solid and secure bond that can withstand extreme weather conditions.

Waterproofing Solutions

One of the most important considerations when choosing a commercial roofing system is its ability to provide waterproofing. Water damage can lead to costly repairs and disrupt business operations, making it essential to choose a roofing system that effectively protects against leaks and moisture.

Several types of waterproofing solutions are available for commercial roofs, including liquid-applied membranes, sheet membranes, and spray polyurethane foam. Each solution has advantages and is suitable for different roofing materials and structures.

  • Hot-Applied Sheet Membranes: This method involves applying multiple layers of asphalt and reinforcing fabrics to create a waterproof membrane. The layers are heated and fused, providing a durable and long-lasting solution for commercial roofs.
  • Liquid-Applied Coatings: These are typically a combination of water-based polymers, such as acrylics or polyurethanes, that are applied in liquid form directly onto the roof surface. Once cured, they form a seamless waterproof membrane that protects against leaks and moisture.
  • Sheet Waterproofing Membranes: These sheets of waterproof material, such as EPDM or TPO, are laid on top of the roof surface and sealed at the seams. They offer a durable and long-lasting waterproofing solution for commercial roofs.
  • Spray Polyurethane Foam: This type of waterproofing involves spraying a layer of foam insulation onto the roof surface, which expands and forms a solid, waterproof barrier. This method is known for its excellent insulation properties and can be used to repair existing roofs.
