Roof Coating Selection

Selecting the best roof coating for your application requires an understanding of site specifics, such as the necessary surface repair and preparation, coating performance and waterproofing. It is also critical to understand the condition of the roof support, slope and drainage patterns of the roof.

Durability

Roof coating durability is defined as how well the coating resists weather. UV inhibitors are more critical in the latitudes closer to the equator. The ability of the materials to resist deterioration and pigments to be UV opaque are critical to protecting the roof substrate. Since solar reflectance and air conditioning energy savings are becoming more important in selecting white roof coatings, it is also important to consider dirt pick-up resistance.

Adhesion and Mechanical Properties

Standing water on a roof may cause a coating to delaminate if it is not formulated properly. Mechanical properties such as elongation and tensile strength can be impacted by climate as well. Coating formulations must resist cracking and therefore roofing substrate as well as climatic conditions should be considered.

DURATEK is experienced is selecting the correct coating for your building. We have an understanding of roof systems, and can match the appropriate coatings to the your roof.

DURATEK is frequently asked which coating is best for my roof? There are numerous roof coatings on the market, and not all roof coatings are created equal. In fact Manufacturers differentiate their products from their competitors through various methods which are quite often found on a Product Data Sheet. However the difference in testing methods, ambiguity in reported data and component properties make it difficult if not impossible to make an educated choice.
