We specialize in a variety of commercial roof coatings.

 Modified systems should be coated every 5 years. Simply just to push the life cycle beyond its normal specified life cycle

Non fib rated coatings are good for industrial metal roof systems. Cool Roofs are GREEN friendly.

Eliminating continuous rusting, protecting the surface from the sun and heat elements.

Fibrated coatings are the standard for modified bitumen systems. Covering cracks and flaws due to heat stress or structural tears. Southern states have a higher need for these coatings as the sun tend to fry and dry these modified systems with in half of their life expectancy.

Costs are less expensive versus the new elastomeric coatings. A modified system is the best base for any flat roof. With proper maintenance which is deductible, the building owner can push these modified flat roofs 30 plus years 

Its all about costs, what works and what will last

Costs break down into square footage price per unit, life cycle costs not 

Today's manufacturers are focusing more and more on reliable coatings such as::

Cool Single-Ply Membranes

Single-ply roofing is the catchall name for roofing materials that come in pre-fabricated sheets and are applied in a single layer to a low-sloped roof. Single-ply roofs are a flexible or semi-flexible roof membrane typically constructed of rubber or plastic materials. Single-ply roofs can be manufactured in a bright-white color for high solar reflectance and increased energy savings.

Single-ply roofs are durable and can cover a number of roof structures. They are typically delivered in rolls, and applied by heat sealing the seams, or with caulk. Some of the newest single-ply roof products are made with self-cleaning and mold-resistant polymers to maintain solar reflectance.

Since the "single-ply" classification includes both light- and dark-colored materials, products that are highly reflective should be selected for heat island reduction and energy savings purposes. Examples of single-ply products include:

Roof Coatings

General Description

Roof Coatings, White

White roof coatings contain transparent polymeric materials, such as acrylic, and a white pigment, such as titanium dioxide (rutile), to make them opaque and reflective. Other white pigments sometimes used are the anatase form of titanium dioxide, and zinc oxide. These coatings typically reflect 70 to 80 % of the sun's energy. Despite the white appearance, these pigments strongly absorb the 5 % or so of the sun's energy which falls in the ultraviolet. Thus, the pigments help protect the polymer material and the substrate underneath from uv damage.

These coatings are applied in thickness considerably greater than typical white paints, ranging up to about 1 mm. Some of the Oak Ridge data in the table show how the reflectance increases with thickness. The substrate must be clean and compatible with the coating system. The achievement of the very highest reflectance values requires sufficient pigment and a smooth substrate. If the substrate is already light in color, it can be made highly reflective with less pigment (fewer coats).

To help maintain the high reflectance of a freshly applied white coating, several issues are important. A completely horizonal roof, with ponding water after rain, is likely to become quickly soiled, with a corresponding loss in reflectance. Of course it is also very likely to fail by leaking! A mildewcide additive can retard biological growth with its resulting stains. There is some variation in how tightly dirt adheres to coatings. 

 

Roof Coatings: Aluminum

Aluminum roof coatings generally employ an asphalt-type resin containing "leafing" aluminum flakes. The term leafing refers to the tendency of the aluminum flakes to accumulate at the exposed upper portion of the coating, which is accomplished with specialized coatings on the flakes. Thus the upper surface is a nearly continuous aluminum layer, which protects the asphalt material from the sun's ultraviolet rays. The aluminum flakes greatly enhance the solar reflectance over the 4 % value for bare asphalt, to above 50 % for the most reflective coatings. The industry regards a visible reflectance above 50 % as a bright coating. (For aluminum coatings, it happens that the visible reflectance is roughly equal to the solar reflectance. This is not true in general due to the fact that about 1/2 of the solar energy content is in the invisible near-infrared region.)

While the 50 % solar reflectance of a bright aluminum roof coating is a great improvement over the performance of a black material, the aluminum content has the offsetting effect of lower infrared emittance.
