Why Use Roof Coatings?

 Roof coating is a form of roofing membrane which is monolithic in nature and is applied fully. ­­It has some elastic properties which enable it to elongate and return to its original shape and size without any problems. Roof coatings come in a wide range of thicknesses, ranging from thickness of paint film all the way to 40 dry mils. What this implies is that it can easily be applied on another roofing membrane without any problems. This is particularly helpful as even a very thin layer of roof coating would sufficiently provide protection to an underlying system from rain, hail, harmful effects of sunlight including infrared and ultraviolet as well as physical damage.

If these are applied correctly and according to the recommended standards, roof coatings offer a seamless, protective surface which is an excellent proofing against leaks and water damage. These are acknowledged to be effective in providing an extended life to almost any underlying roof substrate. These provide a cool surface and protect against adverse weather conditions. It must be noted however that cool roof coatings should not be used upon existing shingles. This is due to the fact that these can prevent the normal drying procedures of shingles which would inevitably give rise to water damage and moisture issues. Care must also be taken when applying on asphalt shingles and asphalt roofs.

There are several benefits to use roof coatings as these have been proven to add up to 25 years to the life of a roof, as well as having the distinct advantage of reducing the amount of roof materials that are no longer in usable condition. They can play a significant part in ensuring that the house remains cool which would ultimately translate into lower electricity bills due to lesser air condition usage.

Risks Involved

The majority of flat roofs aren’t appropriately steep, which causes water to mess in several areas, particularly around the drain pipes and scuppers. Various roof coatings aren’t graded or guaranteed for “Ponding Water”, therefore might stop working pre-maturely if subjected to standing water for long intervals. Give serious attention to the overall performance and restrictions of the coatings being picked. Some companies will guarantee their coatings which includes ponding water. Usually, companies for polymer-bonded coatings don’t include guarantees for ponding water, but some polyurethane companies do.

Roof coatings are remarkably easy to install and apply on a growing number of surfaces. If you have a small or medium house, you can make a weekend project out of coating your roof – it is so simple that in most cases, hardly any professional help is required. However, in cases of large roofs, it is advisable to seek the assistance of professionals as there can be countless complications involved.

Keep in mind that roof coatings are not especially useful on surfaces that are expected to undergo consistent pressure and friction, such as pedestrian areas or traffic populated surfaces.
