Did you know that the angle of your roof affects the materials you need to choose in the re-roofing process? When it comes to a flatter, low sloped roof, there are many quirks and things to take into consideration when it’s time to revamp. Here are some essential tips to a successful roof repair or replacement on a roof with low pitch.

How do I know if I have a low pitch roof?

Do not try to get up on your roof and measure its angle! It’s best to call a professional, who can take a look and tell you the answer. Luckily, many companies, like us here at Energy Shield, offer free inspections that you can use to kickstart your re-roofing.

The Quirks of a Low Sloped Roof

Lower pitch (or lower steepness) roofs on homes are striking, geometric, and modern. They can be found on many different styles of homes, like modernist or prairie. If you’re familiar with Frank Lloyd Wright’s architecture style, you’ll find that many of his buildings flaunt a low sloped roof. Even in completely different house styles with high slopes, many homes have a low sloped section above their porch or garage. They’re more common than you think!

Flatter roofs are more susceptible to leaks. They trap rainwater because it can’t roll down as easily as on a steeper roof. To avoid water damage, make sure to hire experts that know how to best prevent it with the right materials.

Materials to Choose in the Re-Roofing Process

Before you know which materials to choose in the re-roofing process, you’ll need to know which ones are off limits. If your roof’s pitch is below 2:12, it cannot use asphalt shingles. Why? This is because shingles cannot handle water sitting on them. If you go ahead and install shingles anyway, that damage will all be yours to pay for, since it violates shingle manufacturer’s codes and instructions.

So what materials can you use?

Standing Seam Metal Roofing

This is one of the best types of roofing for a low sloped roof. The seams in this type of metal roofing guide water down to keep it out. It’s a low maintenance option that, although costly, ultimately looks great, works great, and gives you peace of mind for decades.

Rolled Roofing

Rolled roofing is a similar texture to shingles, but it’s a large, flat surface that comes in a roll. You’ll often see this on houses that have shingles on the higher pitch areas because it keeps a consistent look. This is a cheaper re-roofing option that is easy to find in many different colors and styles.

Membrane Roofing

Membrane roofing is a system that makes your roof waterproof. The material of the waterproof membrane can vary. EPDM is a sturdy rubber option. PVC is great for hotter climates because it reflects away the sun, keeping your home cooler. Torch-down roofing is another membrane that activates by fire.

Confused on which material option to pick in the re-roofing process? Talking to the professionals is the best way to kickstart a successful low-sloped roof revamp.
