Coatings

One of the most common forms of flat roof treatment is roofing paint. The paint is applied to the surface of the roof to add protection from leaks and to prevent the roof from absorbing heat from the sun. The paint is usually made of a flexible epoxy that acts as a barrier against moisture. Typically the roofing paint is white or some other light colour. Sometimes asphalt or gravel is glued on top of the paint for an additional barrier, and to make the roof a little more attractive. Tar and asphalt adhesive coatings are also used.

Repair

Another kind of flat roof treatment is leak repair. This kind of treatment is used to seal leaks or add additional covering to the roof to make it water tight. Tar paper is often used as a base for leak repair, with asphalt tiles or gravel glued over the paper to form a watertight bond. Silicone sealant is also used to seal gaps around pipes and chimneys that stick out from the roof. Epoxy resins can also be used to seal roofs.

Benefits

There are many benefits to flat roof treatments. The first benefit is a longer-lasting roof. Using proper roof treatments, you can significantly increase the life of a flat roof. Another benefit is reduced electricity bills. Most roof treatments for flat roofs include a radiant barrier for sun protection. Another benefit that occurs from flat roof treatments is lowered repair costs. If the roof is given an effective treatment to reduce leaks and wear on the roof, the cost of repair and replacement will be much less.

Drawbacks

There are a few drawbacks to using a flat roof treatment. If the treatment is applied over a damaged roof, moisture can seep into other areas of the roof and actually increase the cost of replacement. Mold and mildew can grow under the roof treatment, causing the roof to cave in under extreme circumstances. Roof treatments can also be expensive. Sometimes the treatment may nearly as much as roof replacement.

Considerations

There are many things to consider when installing a flat roof treatment. If you want the treatment to guard against leaks, you will use a different treatment than if you want the roof to guard against sunlight. You will also have to consider whether you want to install the treatment yourself or if you want to pay a professional.
