What is a flat roof?
A flat roof is, well, basically just that. It’s either nearly flat or has a low pitch. While sloped roofs typically have shingles overlapped like fish scales so water slides over them, a flat roof is a continuous surface designed to perform optimally and maximize usable space.
There are three major classifications for flat roofs: metal, plastic or rubber membranes, and tar-based. Although suitable for single-family homes, flat roofs are perfect for multi-family, commercial, and industrial uses. Typical structures with this roof type include:
- Apartment buildings
- Schools and universities
- Storage facilities
- Industrial sites
- Transportation buildings
Flat Roofing Advantages
The most significant advantage of a flat roof is the cost. From materials to installation, flat roofs typically are less expensive than traditional ones. The flat surface lowers injury risks, reducing labor costs. Repairs are quick and easy.
Another benefit of flat roofing systems is the ability to serve many functions. Air-conditioning units go on the roof instead of the ground, saving space and protecting against theft or vandalization. Flat roofs can also support solar panels that lower electricity usage.
Since flat roofs don’t have a steep pitch, they’re easy to walk on. You can have a rooftop lounge area, employee breakroom, or storage area. Uses for commercial flat roofing systems are limitless.
A flat roof also maximizes all available interior space. Without the sloped walls of pitched roofs, top-floor spaces, or finished attics are possible.

Types of Flat Roofs
From superior weather protection to enhanced usability, flat roofs are a popular roofing solution for commercial and industrial buildings. Before making the jump, it’s important to consider all available flat roof materials for all your commercial flat roofing needs in Portland, Oregon or and of the surrounding areas.
Comprised of steel or aluminum, this roofing system is incredibly durable. When properly installed, a metal roof can far outlast the structure it supports. As excellent conductors of heat, they’re ideal for colder climates. Roof panels lock together, preventing moisture, debris, and pest intrusion. Although suitable for flat-roof applications, metal is more beneficial for structures with a minimal or low-slope roof.
Ethylene Propylene Diene Monomer, or EDPM, membranes
EPDM is an extremely durable roofing membrane comprised of synthetic rubber. It’s lightweight, flexible, and perfect for flat and low-slope roofs. These membranes resist wind, hail, ultraviolet light radiation, thermal shock, and extreme temperatures. The entire surface of EDPM has an adhesive coating, which keeps roofs watertight for years.
Built-Up Roof, or BUR
Comprised of hot tar and gravel, BUR is one of the most affordable flat roof systems. It’s constructed of waterproof ply sheets sandwiched between layers of hot tar. Gravel or smooth river stone adds stability and durability. BUR roofs are incredibly fire-retardant but very heavy, which adds stress to a building. This roofing system is inappropriate for some applications because installation is messy and molten tar has a strong smell.
Polyvinyl chloride, or PVC, membranes
These membranes are constructed from a continuous filament lattice called a scrim, which is laminated with ultraviolet light-resistant thermoplastic. PVC membranes are lightweight, flexible, and flame-resistant. Seams are welded together, eliminating leaks and interior dampness. These attributes cut down on areas where mold and other fungi could grow. Some PVC membranes use two-way venting, which reduces trapped moisture.
Washington Roofing Company is a proud installer of Duro-Last, the world’s leading PVC roofing system. It’s strength, durability, and weather-resistance offers peace of mind while saving money over the long run.
Thermoplastic Polyolefin, or TPO, membranes
TPO is a single-ply membrane manufactured from polymerized polypropylene and ethylene-propylene rubber. Easily bendable and weldable, it’s perfect for roofs with odd shapes, obstructions, or protrusions. A lightweight but robust construction offers superior resistance to punctures, tears, and impact forces. This roofing material’s white color reflects sunlight and heat, reducing the amount of energy required to keep a building cool in hot climates. TPO membranes repel bacteria, algae, and dirt. They can also withstand ultraviolet light and chemical exposure.
