1. Types of Flat Roof Materials

There are three main types of flat roofs: built up, single ply and paint on/spray on. The most popular and durable are single ply roofs, used in both residential and commercial construction. They include EPDM, PVC, and TPO. Each are composed of different materials, and have different costs, durability specs and formulations.

2. Installation Methods

Flat roof installation can include mechanical or fully adhering methods. To attach single ply membranes with the mechanical method, the rows of the membrane are adhered to the roof with barbed plates or roof screws. A fully adhered flat roof’s membrane is glues directly to roof substrates. Reputable roofers trained in installing flat roofs will determine which method is best for your home or building to avoid leakage.

3. Longevity

The lifespan of a flat roof can vary greatly, and is extremely dependent on the skill of installers, your structure, and the environment. Many warranties are available to help the financial commitment of maintaining a flat roof, although ponding water or failing seams are often not covered. In general, however, a lifespan range is estimated between 10 and 25 years.

4. Repair and Maintenance

Flat roofs require professional attention, as their repair needs are very specific. For example, the seams of PVC roofs can be re-welded throughout their service life making installation modification or maintenance of new equipment simple and fast for a professional. Built-up roofs require some expert attention as leaks are difficult to locate and repair.

5. Unique Benefits & Energy Efficiency

The flat roofs are the ideal choice for large buildings, as pitched roofs will be more difficult and costly to install, requiring special engineering. Additionally, some flat roofs can be used penthouses, patios, green roofs or even decks – the possibilities are endless!

Any job that you consider doing on your home, make sure to hire a fully licensed and insured contractor to protect yourself. If in doubt, check them out by calling your local county/city building department. Never let anyone talk you into “pulling the permit” for any job on your home as that is the contractors responsibility to take care of all necessary permits. If the person/company, you are wanting to hire cannot acquire the permits to do the job, chances are they are not licensed to do the work.
