COMMERCIAL ROOFING MATERIALS: LOW-SLOPE VS STEEP-SLOPE
Your roof is very different from the one on your commercial building. Both roofs are built to last and protect, but each one has its own unique characteristics that make them better suited for their intended purpose. We have the answers to all your questions about a replacement commercial roof.
What is a Low-Slope Roof?
Many commercial roofs feature a low-slope design. Low-slope roofs have a ratio of 2:12 or less. It rises 2 inches for every 12 inches. This roof is not suitable for shingles or other roofing materials. Modified bitumen or single-ply are the two low-slope roofing materials.
Modified bitumen is a traditional type of commercial roofing. This asphalt-based roofing system is suitable for both flat and low-slope roof designs. The roof is applied in layers of asphalt sheets. These layers create a durable, waterproof, weather-resistant and energy-efficient roofing system. Modified bitumen roofs can last up to 25 years.
Single-Ply Commercial Roof
Single-ply roofing can be used to provide a single layer protection. It is usually made of thermoset (EPDM), thermoplastic (TPO) or PVC (KEE). This roofing type is usually less expensive, more reflective, and easier to install. Single-ply roofs can be placed over existing substrates and are very energy-efficient. They can also last for up to 25 year.
What is a Steep-Slope Roof, and How Do You Know It?
The steep-slope design is naturally attracted to gravity, allowing water and debris to easily fall to the surface. This makes maintenance easy for these types of roofs. It is compatible with roofing materials such as asphalt shingles, metal, and tile.
Asphalt Shingles are made from fiberglass or felt paper and coated with an asphalt waterproofing layer. These shingles are covered with ceramic-coated aggregates, which come in many colors and are protected from the sun’s ultraviolet rays. There are three main types of asphalt shingles:
- 3-tab shingles
- Architectural shingles
Asphalt shingle is one of the most cost-effective roofing materials. It is easy to install and requires little maintenance.
Metal roofs can be made from copper, zinc or aluminum. When painted with a cool roofing coating, this type of roofing is light and efficient. Metal roofing can last for up to 70 years. It is also resistant to fire and can withstand extreme weather conditions.
If your roof slopes steeply or moderately, tiles may be an option for commercial roofing. They are attractive and durable. A tiled roof can last up to 50 years. You can also choose from a variety of colors, shapes, or materials for tiles, such as:
Tiled roofs are more expensive and take longer to install. The tiled roof is also heavier, so your contractor might need to install structural supports.
