Many commercial buildings use low slope roofing, which has led to the misconception that they’re exclusively for commercial or industrial use. However, many modern homes have low-sloped roofing, and even if your home has a high slope, you may find that your garage or patio will have a much better profile with something less tall.
Authentic Restoration in Raleigh has helped hundreds of homeowners install low-sloped roofing, and we can do the same for you. Get in touch at (919) 604-7683 to schedule a consultation today!
What Is a Low Slope Roof?
Low slope roofing is any roof with a slope of less than 3-in-12, meaning that it goes up three inches for every 12 horizontal feet. It’s important to note that low slope roofing isn’t completely flat since it still needs a way to shed water.
The main challenge of low slope roofing systems is water. High-slope roofs rely on their slope to move water into the gutters. Low slope roofs have a slight slant, but this may not be enough to get water to move during lighter rains. That’s why low slope roofing systems need to be entirely watertight to the roof’s edge or a specified drain.
The Benefits of Low Slope Roofing
If you’re replacing your existing roof or installing a new one, low slope roofing should be a consideration. It offers several advantages over traditional high-slope roofs and may be a better fit for your home.
Greater Energy Efficiency
The air in an attic can dramatically influence the effectiveness of heating and cooling systems—the less air, the more effective the heating and cooling. Low slope roofs have much less dead attic space, making the entire home more energy-efficient.
High slopes increase the chances of slips and falls, while lower slopes are easier to navigate. Not only does this improve safety, but it means that maintenance is more affordable since the roofing contractor will be able to perform maintenance faster.
More Affordable Installation
Low slope roofing requires less labor and roofing materials to install than high pitched roofs. This ease of installation translates directly into a more affordable option, which can be vital if you’re on a tight budget.
Common Low Slope Roofing Materials
Just like traditional roofs, there’s a whole range of low slope roofing materials to consider. They each have their own benefits and drawbacks, so consult with your contractor on which one is the right choice for your situation.
Tar and Gravel Roof
A tar and gravel roof consists of several layers of roofing felt and a tar compound called bitumen. These layers make a watertight membrane that protects the entire roof. The final step is the addition of a gravel coating embedded in tar.
Modified Bitumen Roof
Modified bitumen roofs use a chemically modified form of bitumen over a heavy fiberglass mat to cover the entire roof. It has better flexibility than traditional tar and gravel and also has excellent performance for the cost.
Single-Ply Membrane Roof
Membrane roof systems are sheets of a synthetic membrane that get heat-welded onto the roof. Single-ply membranes are heat-reflective, easy to install, and are rapidly becoming the most popular low slope roofing system. The membrane is also fire-resistant, making it an ideal choice for fire-prone areas.
One aspect to consider is that most membranes are white to reflect the sun, which can clash with your home’s style, especially as it starts to get dirty. You can choose alternative membrane roofing materials that are darker, but it’s a trade-off between insulation and style.
Metal roofs are becoming increasingly popular for both high and low slope roofing. You can choose from a large selection of colors, textures, and sizes to customize your roof’s look. Metal is also incredibly durable and effective at directing water to drains and gutters.
