Thanks to improved technology, flat roofs are rising in popularity. But there are still many factors to consider when choosing to install one.
If you’re considering an addition to your home, have limited space for outdoor HVAC units, or are looking to enhance a minimalist aesthetic, a flat roof is a fantastic option for you. Before you commit to one, however, be aware that there are many things to consider before you install one.
Flat roofs are not actually flat. They are also known as low-slope roofs because their pitch is typically at or below 3/12. The low pitch can cause problems during extremely wet weather.
Longevity and durability used to be a major problem for flat roofs since water displacement takes longer. However, recent advances in flat roof membranes have put them on par with most steep slope roofs.
If you’re considering installing a flat roof, it’s important to know what type of membrane you’ll need, because you WILL need a membrane. Each will vary in cost and the amount of maintenance needed, but our Exterior Remodel and Design experts can help you choose the best the option for your Omaha home.
Here are the major types:
- Single-Ply roofing uses one layer of membrane as the waterproofing and weather surface. The three most popular sinle-ply membranes are EPDM (Ethylene Propylene Diene Monomer), PVC (Polyvinyl Chloride), and TPO (Thermoplastic Olefin).
- Built-up roofing is manufactured using the tar & gravel method, modified bitumen, or rolled asphalt. The layers used for this membrane increase the durability of your roof, but will become heavier, and the roof needs to be properly reinforced.
- Spray-on/Paint-on roofs are typically used for decks or installed on top of existing single-ply or built-up roofing to extend their service life. These membranes eliminate the seams in membranes, giving more protection against leaks.
