Here at Treadlite Roofing, our clients frequently ask us about the difference between the slope types, specifically because of how roof slope can impact their home’s design. Most roofing companies will have plenty to say about the choice of roof slope, but generally, the two choices are either a low, steady slope or steeper slopes. Here’s the difference between the two and their benefits.
The biggest difference between low and steep slopes is the slope height. The general way of showing the height of a slope is the number of inches it rises over every inch across the entire length of the rooftop. So, for a standard flat roof, the slope rises a little bit below 2 inches every 12-inch run, so that’s 2:12.
The angular difference between a low slope and a steep slope is fairly high. A low slope tends to run for around 2:12 to 5:12, which is pretty much close to a standard slope of between 9.5 degrees to 18 degrees. Meanwhile, steep slopes bring the rise up to 21:12 or higher, which is greater than 18 degrees.
Benefits of a Low Slope
One of the biggest benefits of a low slope is that it is very easy to maintain. The very low slope means it won’t be as risky for an inspector or roofer to access it. They will require fewer pieces of safety equipment, which can make maintenance, repair and roof replacement easier.
The lower slope also means the area beneath the roof and the ceiling is smaller. This is a good thing because there’s less area that can trap heat. The heat can easily affect the HVAC system of your home. Having less space for heated air to accumulate can do wonders in improving the internal temperature of the rest of your home – something that a low-sloped roof can help you with.
Benefits of a Steep Slope
On the other hand, steep slope roofs offer plenty of protection against extreme weather. The steep slope alone makes it a great defense against water pooling; there’s virtually no danger of this with a roof that has an 18 degree slope or higher. And, that doesn’t just stop with water; snow hardly piles up on steep roofs.
The attic space created by a good steep roof is also something worth considering. The high pitch creates a spacious area underneath that can be utilized efficiently, either as an attic or an extra room. This is one of the reasons a church roof installation is commonly steeply sloped; the added space creates a cavernous structure that’s great for carrying sound.
One last benefit of installing a roof with a steep slope is the fact that it helps a lot in keeping moisture away from the roof. A bigger space between the roof and the ceiling means more ventilation space. This is a great way of reducing the amount of condensation in your attic space and on your roof.
