Commercial Roofing: What Is It?

Protecting your property is the main purpose of both residential and commercial roofing systems. The materials used in their construction and installation, however, are very different.

For commercial roof replacement systems, commercial roofing contractors frequently utilize single-ply (PVC, TPO, EPDM), built-up roofing systems, modified bitumen, concrete, tar and gravel, and other materials. Residential structures may have concrete tiles or asphalt shingles put on their roofs, depending on the environment.

Since there are more options for commercial roof repair systems than for residential roofs, you must do extensive research and choose a reliable commercial roofing company that offers a wide range of services to guarantee positive results.

Do You Need to Replace Your Commercial Roof?

What roof deterioration symptoms point to the need for a replacement?

  • Water pools – If there are water puddles on your roof, the drainage system has probably failed.
  • Flashing that has been damaged should be replaced since it hides roof seams. Water may therefore seep through the seams if it is weak and you are unaware of it earlier, necessitating a repair.
  • After nearly 15 years of usage, these defects typically manifest as cracks and tears.
  • Roof leaks – If you don’t immediately remedy leaks, they might cause serious issues like mildew or mold.
    Water stains – Stains of water on the ceiling may indicate a leaking roof.
  • Rips in your roof’s membrane – PDM rubber roofs, the most common type of commercial roof, include protective rubber membranes. The waterproof barrier will become compromised, allowing moisture to enter the building.
  • Unattached or loose EPDM membrane – If your roof’s membrane flaps in the wind, your structure is not being protected.
  • Roof membrane bumps are often an indication of loose fasteners.
  • If there is mold visible or odorous in your building, water may leak through the roof, endangering the health of the people.

    Types of Commercial Roofing Systems

    We have included the many types of roof systems here for your convenience. Reviewing the following categories:

    EPDM Roof Membrane or Thermoset

    Commercial roofs, also known as EPDM roofing, are versatile, durable, and simple to maintain in comparison to other thermoset roofing. It features a simple installation process, is constructed of single-ply rubber components, and is ozone and UV light resistant.

    The resistance to acids, alcohol, and solvents, flexibility at milder temperatures, and reflective qualities that can help lower cooling costs are other advantages of EPDM roofing.

    Thermoplastic or TPO & PVC Roof Membrane

    For second-generation installations, TPO (thermoplastic polyolefin) and PVC (polyvinyl chloride) roofs work best. They are thin, incredibly reflective, impervious to chemicals, UV light, piercings, and bacterial growth. Restaurants, hotels, and other establishments that employ ventilation systems that emit oils are suitable applications for TPO and PVC commercial roofs.

    Green Roofing System

    In recent years, green tops have emerged as a sustainable real estate option. They can resolve drainage and water problems while also boosting efficiency. They are also attractive and environmentally beneficial commercial roofing materials.

    Built-up or Membrane Roofing (BUR)

    The most popular gravel and tar roofing technique is known as built-up, or BUR roofing. It has many layers or heaps, which makes the system more resilient. If you’re looking for a long-lasting, budget-friendly choice, BUR is a wonderful roofing solution.

    A metal roof

    Metal roofs are a common style of business roof. There are a variety of materials available, including metal tile sheets, stainless steel, corrugated galvanized steel, silicon-coated steel, stone-coated steel, aluminum, copper, tin aggregates, and zinc.

    Commercial metal roofs also have strong fire resistant benefits and a long lifespan. To prevent corrosion and fading caused by sunshine or other environmental factors, they usually include protective coatings. Additionally, they are a desirable choice that helps make your building’s construction more environmentally friendly.

    Modified Bitumen Roofing

    The roof’s structure is made up of layers of reinforced roof fabrics and bitumen. Mod-bit roofing refers to a commercial roofing repair system made of modified bitumen. It is two-ply attached to tops in order to provide the most solidity and security.

    Commercial flat roofs lack the tensile strength of modified bitumen roofs, which also cost less to maintain. Furthermore, if you anticipate a lot of activity, it is perfect for commercial roof repair.
