EPDM – Rubber Roof Systems
Rubber roofs make up a large percentage of all flat commercial roof systems. Rubber roofs are a single-ply roof, meaning they are composed of a single layer of roofing material that is attached to the roof in one of three ways: mechanical attachment (nails, screws), fully adhered (glue, adhesive), or ballasting. They are valued for their affordability and durability – in fact, some rubber roofs are more than 60 years old!
Here are some of the most common issues that afflict rubber roofs:
- Faulty seams
- Loose flashings
PVC Roof Systems
PVC roofing or polyvinyl chloride is another single-ply roofing solution commonly used on commercial roofs. PVC is valued for its flexibility, natural resistance to fire, low material weight, and ability to withstand exposure to many chemicals.
Here are some of the most common issues that afflict PVC roofs:
- Tendency to shrink, pulling seams and lifting corners
- Punctures easily, especially in cold weather
TPO Roof Systems
TPO (thermoplastic polyolefin) is the third type of single-ply roofing membrane. TPO membranes primarily come in white, grey, and tan, and are installed using hot air-welding equipment. They are prized for their resistance to grease and high wind ratings.
Here are some of the most common issues that afflict TPO roofs:
- Seam failure
- Sun damage
- Cracks from weathering
Built-Up Roof Systems
Built-up roofs are also called asphalt or tar and gravel roofs. It is one of the older, heavier, but most reliable roofing systems. It involves layering roof felt with bitumen, a sticky, oil-based material. The top is coated with gravel to add another layer of protection against weather and sun.
Here are some of the most common issues that afflict built-up roofs:
- Alligatoring – small cracks due to shrinkage
- Blisters or bubbles filled with air, vapor, or water
- Ridges due to thermal expansion
Spray Foam Roof Systems
Spray polyurethane foam is a popular roofing systems for flat commercial roofs, despite the fact that its one of the most expensive options. It’s energy efficient, waterproof, and extremely lightweight. It can be installed right over the top of most existing roof systems, saving you money and time when you need a new roof. When topped with a cool roof coating, it can withstand harsh weather and sun exposure for 25 years or more.
Here are some of the most common issues that afflict spray foam roofs:
- Extremely susceptible to punctures
- Low spots causing standing water
Modified Bitumen Roof Systems
Modified bitumen roofing systems are also called torch-down roofs. This material is rubber-backed on one side and granule-topped on the other. The rubber side is heated until it melts, and then stuck down onto the roof’s fiberglass base sheet.
Here are some of the most common issues that afflict modified bitumen roofs:
- Seam defects
- Improper installation
- Punctures from tree branches, foot traffic, dropped tools, etc.
- Fastener failure
- Air-filled or moisture-filled blisters and bubbles
