Everything You Need To Know about Flat Roof Types

House with a flat roof

There are three main styles of flat roofs, and each type has a unique set of pros and cons. In case you are torn between the ideal model to choose for your structure, you could seek the guidance of a skilled roofer. Here is a summary of the available flat roof options in Utah and the basic facts that you should know about them.

Tar and Gravel

This type of flat roof is also known as BUR (Built-Up Roof). It consists of not less than three layers of quality waterproof materials, and hot tar is used alternatively between the plies. Ballast is also used to ensure the stability of the roof, and it also adds to the curb appeal of the area. Tar and gravel flat roofs are stable and beautiful, but the downside is that this option is heavy and sometimes, parts of a building must be reinforced to provide proper support for the roof.

Modified Bitumen

Modified bitumen level roofs are easy to install. They are made up of one layer that could be spread out over a surface. Depending on the style you choose, you could directly apply modified bitumen to a surface, or you may have to first apply temperature to the material with a blowtorch before installation.


EPDM is rubber membrane that can be glued on the rooftop, ballasted using stone or anchored with fasteners. It is lightweight and not vulnerable to the damaging rays of the sun. It is also durable and tear resistant. Depending on your budget and also your objectives, you could choose the conventional black EPDM shades or opt for treated styles that tend to be lighter in color.

The installation process involved when constructing flat roofs is quite different from what happens when handling traditional sloped roofs. It is in your best interests to do more than seeking the expertise of the first roofer that you can find. Whether you want installation, maintenance or a replacement job, hiring the right contractor could better your chances of making a worthwhile investment.
