Waterproofing Roof Coatings Keep Buildings Dry

Waterproofing roof coatings provide a watertight seal for commercial, institutional, and industrial roofs. The ideal coating will also prevent protect a roof from further attacks of weathering, future roof leaks, and go on easily for the best roof waterproofing results.

The best waterproof roof coatings are now designed as “elastomeric roof coatings”. Among their water resistant capabilities are the ability to meet the current weather conditions and adapt to ever-changing weather conditions as well.

Roof Coating Chemistry
Elastomeric roof coatings used in waterproofing roof coatings contain any one of various polymers that have the elastic properties of natural rubber. By not containing any water, they are stronger, can provide more protection and transfer less moisture.

In addition, the properties of such coatings enable them to be more pliable and stretch more than water-based coatings; to be up to eight times stronger than their water-based counterparts; and over time can be up to twenty times more resistant to moisture than typical coatings which are made completely of acrylics.

Companies that specialize in waterproofing roof coatings manufacture high-performance, time-tested systems and products for waterproofing walls and roofs.

Cool Roof Coatings
A cool roof is one that radiates heat back into the atmosphere rather than allows it to be absorbed. A cool roof coating, also known as a white roof coating, is a liquid membrane that is applied to a roof surface to reflect the rays of the sun so as to create a cool roof. The elastomeric coatings that are used for cool roofing also offer waterproofing benefits.

The primary benefit of using a cool roof coating is to reduce energy costs. The need for air-conditioning in a commercial building can be reduced by as much as 100 degrees with the use of a cool roof coating. Consequently, cooling equipment can operate more efficiently so future needs for maintenance can decrease.

The surface temperatures of a roof can also stay more consistent that can extend the life of a roof by diminishing movement and shielding a hot roof from the thermal shock of cold rain. Cool roofs also provide complete protection from ultra-violet rays.
