Just like there are numerous roofing materials for pitched roofs, there are just as many options for flat or low-sloped roofs. When you’re in need of a new flat roof, you might consider some other flat roof materials other than what you’ve been used to.
Our guide will walk you through the best and most common types of flat roofing materials based on what the pros recommend. By the end, you’ll have a good idea of what might be your best bet!
A flat roof is a type of roofing system that has little to no pitch, making it almost completely level. Though there are a few different types of flat roofs, the two most common are built-up roofs (BURs) and single-ply membranes. Other than their low slope, flat roofs differ from standard roofs in a few ways:
While the most commonly used flat roofs are BUR or EPDM, there are a few others to choose from that can be beneficial depending on your budget, climate, and level of upkeep.
BUR or built-up roofs consist of layers applied to the substrate, which is usually asphalt and felts. To get a watertight roofing system, these layers are necessary, and regular flat roof maintenance prevents moisture build-up and other issues. With proper installation and maintenance, a BUR roof can last 20-30 years.
A single-ply TPO roofing system is a newer material on the market that has only been around since the 1990’s but has been growing in popularity. It’s made of two main ingredients: ethylene propylene rubber and polypropylene (plastic). The two are then merged with heat and pressure to create a tough, weldable membrane that lasts anywhere from 10 to 25 years. At Anchor Point, we love to use both GAF and Johns Manville membranes for our TPO roofs.
Another popular option for flat roofs includes a rubber roof or EPDM (ethylene propylene diene terpolymer) roof. They’re great for both commercial and residential buildings and can last for around 20 years with proper installation and maintenance.
Modified Bitumen is a two-ply flat roof material that is applied using self-adhesive strips. This type of flat roof has a base sheet (we prefer the Liberty brand base sheets) and a cap sheet and can be heat or cold applied, which makes it very DIY-friendly.
PVC, otherwise known as polyvinyl chloride or plastic, is a great roofing solution for those who are looking for single-ply options. In comparison to TPO and EPDM roofs, it contains less oil and petroleum and offers a lot of substantial benefits to a flat roof.
Metal roofs are an uncommon but possible roof material to use with flat roof applications. This is especially true for residential roofs with a flat or low slope portion that a homeowner wants to match the aesthetic of the rest of their home which can warrant the use of metal. If you’re looking for a roof that will last you a while, this type of roof is a great option.
As you can see, there are so many different types of flat roof materials to choose from— it can be tough to choose the right one. That’s where a professional like Anchor Point can come in helpful.
Choosing the right flat roof material for your home of business is a big decision, but at the end of the day it’s the installation that will matter most. Even the best materials on the market can be rendered useless if installed incorrectly. This is why it is crucial to do your research to find a qualified roofing contractor specialized in flat roofing. This will ensure your roof is set to protect your home or business for years to come.
