The term “low slope” roof gets thrown around a lot when talking about the best rooftops for buildings, especially commercial roofing, but the term isn’t very illuminating and deserves a closer look when considering roof upgrades or new installations.
Let’s take a closer look at what exactly low slope means, the real benefits that low slope rooftops have, and why they tend to make good choices for commercial projects.
The Truth Behind Low Slope Rooftops
A low-slope rooftop is any roof with a particularly low pitch – low enough that you cannot effectively use shingles on the roof. For many commercial buildings, these slopes are so low they may look flat at first glance. However, low slope rooftops are always designed so that they have the right pitch and drainage options to channel off water. This helps prevents water from forming long-lasting puddles after rain, which can damage the roof.
Most low slop rooftops have a pitch ratio of 2:12. That means for every 12 inches the roof covers horizontally; it rises two inches or less. The flat nature of these rooftops means that roofing materials can quickly be applied in rolls of protective layers – and they have other benefits as well. Let’s take a look at why businesses should always consider low slopes for their buildings.
The lower the slope, the fewer materials need to be used in roof construction, which leads to significant cost savings for everyone involved. Low-slope roofing materials and membranes are also designed to be installed quickly and maximize their coverage, which makes them ideal fits for large rooftop spaces that need protection. Where more durability or a unique appearance is necessary, there are also metal panels and other alternatives that can provide different advantages.
The higher the slope of the roof, the more it has to deal with the wind, and the more precipitation it encounters. That leads to extra wear and tear that can cause problems while reducing the life of the roof. A low-slope roof doesn’t have to withstand as much pressure from the wind
Low slope rooftops can also be installed with reflective layers and lighter-colored materials that can reflect more sunlight. This may not seem like a significant difference, but during the hotter days, larger buildings like warehouses can absorb high levels of heat from sunlight, which means that cooling systems have to work much harder to keep the building at a reasonable temperature. Reflective layers reduce this heat absorption, saving wear on AC systems and energy bills.
A low slope roof is relatively easy to patch if something goes wrong. An experienced technician can inspect a roof for damage (after a storm) and make quick repairs before serious leaks can develop.
