Low slope roofing is typically used for commercial buildings such as warehouses, factories, industrial buildings and multi-family housing units. Another term used for low slope roofing is flat roofing. If a roof is considered to be a low sloping roof then that means it has a slope of less than 3 inches per foot which accounts for the roof level going up less than 3 inches vertically for every horizontal foot. There are a handful of reasons for choosing a low slope roofing system over steep slope roofing but before deciding you need to know about low slope roofing first.

Basic Purpose

As many would conclude, all roofing systems have to be built with a proper drainage system. If it rains and the water has nowhere to go then the structural integrity of the roof can quickly become a problem. For low sloping roofs, water is directed into drains known as crickets and saddles which are created to direct water on the roof to fulfill this basic purpose. These drains are located at the low points of the roof called valleys where two slopes meet at a low point. Since drains are known to get clogged from time to time an interior and exterior drainage system is often built in case one of the drainage systems becomes backed up.

Easier To Maintain

Have you ever looked at some roofs and thought to yourself you’re glad you never have to go up there? Some roofs can be so steep it’s a wonder that even professionals can maneuver around on them. Flat roofing systems are by far easier to get around. There is less risk of someone slipping or falling off the roof with this type of slope making it easier to maintain for both owner and roofing maintenance crews.

Going Green?

If going green is one of your top priorities then you’ll be glad to know that low slope roofing happens to be the most compatible with current solar paneling. The other bonus is that the average cost of solar PV panels has dropped to nearly 70% since 2014 making them more economically competitive with conventional energy sources in most states. At this time, over 3% of the U.S. electricity comes from PV (photovoltaics) and CSP (concentrating solar-thermal power) solar energy and is only projected to increase.

Following The Trends

Multi-family housing can not be built fast enough! People are moving all over the U.S. and the housing market can barely keep up with them. That being said, multi-family units are going up quickly and many of them are looking at following the trends to bring in certain demographics to their area. With modern and contemporary design schemes being the most popular housing unit trends, low slope roofing just happens to fit right in and the added bonus is that low roofing systems are less expensive since fewer materials are required; a plus for all multi-family housing development owners.

Energy Efficient

Energy efficiency is always something that consumers look at especially with larger purchases. The benefit of low slope roofing is that it improves heating and cooling in comparison to steep slope roofing. This is because there is less attic space that would normally fill up with excess air. Without this aspect, heating and cooling systems can run less making them energy efficient.

When it comes to the many types of roofing styles there are many details to look at before choosing which option works best for you. Low slope roofing has a variety of configurations to choose from. Deck types, insulation requirements, roof membrane requirements and other factors will also play into which low slope roofing type is best suited for your building. Working with a professional roofing contractor will help you determine which low slope roofing system and application process is best suited for you.
