Commercial roofs range from low-slope rooftops to high-slope roofs, and each type requires different techniques, materials and maintenance. Understanding the different types of commercial roofs can help you choose the best one for your building and climate, as well as determine what type of maintenance is necessary. In this article, we’ll explain the different types of commercial roofs and the benefits they offer.
A low-slope roof is one with a pitch of less than 3:12. This type of roof is often made from modified bitumen, thermoplastic polyolefin (TPO), metal and even sprayed polyurethane foam (SPF). Low-slope roofs are easy to install and require less maintenance than other roofing types. They’re also great for buildings in areas with a lot of rain or snow, as they are better able to resist the elements.
Low-slope roofs offer a range of advantages, including:
- Easy installation
- Modern look
- Energy efficient
- Durable performance
- Low maintenance
Despite the benefits, low-slope roofs also have some drawbacks, such as:
- Increased risk of leaks
- Higher initial cost
- Poorer drainage
- Lower thermal insulation
High-slope roofs have a pitch of 4:12 or steeper. They’re usually made from asphalt shingles, slate, clay or concrete tile, metal, and wood shake. These roofs are more expensive and require more maintenance, but they’re great for areas that get a lot of snow or rain. High-slope roofs also improve the efficiency of your building by providing extra insulation.
High-slope roofs have several benefits, including:
- Improved drainage
- More efficient insulation
- Better snow and rain protection
- Increased aesthetic appeal
Although there are several advantages to high-slope roofs, they also have some drawbacks, such as:
- More expensive upfront cost
- Increased maintenance requirements
- More complicated installation
People Also Ask
What Is the Optimal Pitch for Commercial Roofs?
The optimal pitch for a commercial roof depends on the climate and type of roofing material. Generally, a low-slope roof is recommended for climates with heavy rain or snow and a high-slope roof is recommended for climates with light precipitation.
Are Flat Roofs More Susceptible to Damage?
Flat roofs are more susceptible to damage from heavy rains, snow and ice. But, with regular maintenance, a low-slope roof can be just as durable and reliable as a high-slope roof.
What Are the Benefits of Metal Roofs?
Metal roofs are durable, low-maintenance and energy efficient. They also reflect heat, providing extra protection from the sun’s rays and lowering cooling costs in summer months.
What Is the Average Lifespan of a Commercial Roof?
The lifespan of a commercial roof depends on the type and quality of material. Generally, a low-slope roof can last up to 20 years, while a high-slope roof will last up to 30 years. Additionally, proper maintenance will extend the life of any type of commercial roof.
Commercial roofs come in a variety of types, each with its own advantages and disadvantages. To ensure success, it’s important to choose a roof that’s suitable for your building and climate. Make sure to research the different types of commercial roofs, understand the pros and cons, and consult an experienced roofer for the best advice for your building.
