Common Commercial Roofing Materials

The most important part of any type of building is the roof. All roofs are designed to protect the rest of the structure. If the structure is not built with a roof that meets the overall structural design, the building would be destroyed by nature alone.

Commercial roofing is a building material used to protect and seal the top of a commercial structure. Unlike residential roofs which have a steep slope, commercial roofs generally have a flat slope.

Different materials are used to create commercial roofing systems and each type has advantages and disadvantages:

1. slate cover Slate roofs are expensive. However, slate can last tens to hundreds of years. So if you consider the longevity of the material, it may turn out to be the most profitable roofing material. Slate roofing materials are beautiful roofing systems available in a variety of sizes and thicknesses. They are also low maintenance because slate is naturally resistant to algae and moss. Slate roofing systems are fireproof and water-repellent. They are also very resistant to hail and wind. Slate is also environmentally friendly in that when it needs to be replaced it can be disposed of as a clean landfill or recycled and used for roofing again.
2. asphalt shingles Asphalt shingles are commonly used in many steep-slope commercial roofing applications. It comes in many colors and styles. They are affordable and application is easy. However, this material deteriorates easily. It is not resistant to high winds and has been known to be blown off the roof. Asphalt shingles heal very easily in the hot sun and are prone to mold and moss in humid climates. This material is also not eco-friendly.
3. metal roof Metal ceilings involve a high installation cost. It is also susceptible to wind damage. It can be quite noisy when it rains or hails. On top of that, a metal roof is easily scratched or dented. Despite these drawbacks, however, it remains a favorite of many roofing experts because it is strong, durable, and fire resistant. It is very low maintenance, ecological and recyclable.
4. built roof These roofing systems are often referred to as “tar and gravel” roofs. It is one of the oldest and most trusted commercial roofing systems for flat roof structures. It consists of multiple layers of roofing felts laminated with bitumen. The original cost of a BUR system is higher than other roofing systems, but it is a favorite of architects, engineers, building owners, roofers and contractors. It has a proven track record of reaching 150 years. It is thick and durable and can be used in waterproofing applications. Even after many years of service, it can still be maintained and repaired to extend its life. However, it can be quite expensive to transport this material. It is heavy and the material is not stable at high temperatures.
5. Modified Bitumen Modified bitumen roofing is asphalt based and closely related to built roofing (BUR) and is also used on flat or low slope roof structures. Modified bitumen offers designers a wider range of options compared to BUR. In addition, modified bitumen products are subjected to the same fire and uplift resistance testing standards that BUR goes through. A big disadvantage of modified bituminous roofing systems is that it is not at all effective on flat roofs because it has only one layer and when there is a downpour and the roof area is totally submerged, water can find even the smallest opening. If this happens, the water will show through your roof.
6. single layer roofs Single ply roofing systems are formed from multiple layers of barriers and insulation that have been mechanically joined together. It is relatively easy to apply as it is light and thin. It is environmentally friendly because it can be recycled. However, these roofing systems are more expensive than other materials. If people are going to step on this material, they will also need a protective surface.

Like other building materials, you need to consider many factors before deciding what type of roofing material to use for your business. While you may have your own preference, it’s best to consult a roofing expert so you can make the right decision.
