Flat Roofing Systems

Roofs are designed to protect the structure below, which is why they come in a myriad of shapes, styles, and sizes. When you look at the history of roofing systems, you can see its evolution over time. With significant advancements in technology and manufacturing, the roofing systems you see today can house elements such as insulation, ventilation, wiring, and piping, while adding to the aesthetics of the house. Most roofs have enough of a slope that they can effectively keep rain from pooling in one area and damaging the deck. However, not all roofing sections have enough of a height difference between the eaves and the ridge – these areas are known as low slope or flat roofing.

Flat Roofing Systems

What is low slope/flat roofing?

A roof with a slight pitch (not more than 18° or less than or equal to 3:12) or almost flat falls under the low slope category. It consists of three main components – roof deck, insulation, and membrane. The membrane is a sheet-like roofing material, which protects the roof from leaks. Although there are various types of membrane systems, built-up, single-ply, and torch-down are quite common in residential roofing.

Why is it different from other types of roofing?

Low slope residential roofing is different from other systems because of the angle of inclination. Thanks to the low pitch, it is more common for leaves and branches to get stuck on low slope roofs, thankfully their smaller angle is easier to clean and maintain. Due to the larger roof overhangs, it protects your decks, doors, windows, and siding. Also, you can install solar panels on them, allowing your household to be independent of energy. One major drawback of low slope roofing is that it doesn’t have enough of an angle to ensure water runs off the roof. The possibility of pooling water on roof sections with a low slope means it is essential to choose the right roofing system.

How does the installation process differ from standard roofing?

Depending on how low of a slope each section of your roof has the materials used and installation method required to complete your low slope roof replacement change. The two systems offered by Pro are Flintlastic and EPDM.


Using a formula of polymers and resins, it converts the bitumen into an adhesive, through a specific manufacturing process. The temperature required to install self-adhering ranges from 45°F – 50°F. This material can be colored to match your the color and style of your shingles.


Any roofing surface with a pitch of 10° or less will require an EPDM system. The roofing contractor applies adhesive to the roof deck with the help of squeegees, sprayers, or rollers. This adhesive helps hold the thick rubber sheets of EPDM to the deck as they are flattened out and any air bubbles are addressed. Once the primary sheets have been applied then any seams will be sealed up with liquid rubber and another strip of EPDM.
