Asphalt Shingles

Asphalt shingles are the most popular housing roofing material in America, and for good reason. They are the least expensive and are relatively easy to install. An asphalt shingle roof can last anywhere from 15 to 50 years. The compositional factors that affect life expectancy of asphalt shingles include:
Shingle weight: The heavier the shingle is, the longer the life expectancy

Shingle composition: Shingle styles that mimic more expensive roofing styles, such as natural slate or wood shake, also add durability because of the higher-quality materials used. Premium shingles may also offer improved impact resistance or solar reflectivity, increasing longevity.

How to protect your roof from sun damage?

Reflective coatings for roofs act as a “sunscreen” to your roof membrane. These coatings act as the barrier in between your roof and the sun that shields the sun’s harmful UV rays away from the roof membrane. The sun is the most harmful element to your roof because the UV rays constantly shine down on top of the roof surface and cause embrittlement, cracking, leaking and premature aging. Reflective roof coating systems are excellent because they preserve the roof and lengthen its life span. These systems can be applied on top of almost any roofing substrate - allowing you to convert your black coloured asphalt roof into a highly reflective white roof or your leaking and aging TPO/single-ply roof into a new, bright white roof membrane.

Different Types of Concrete Coatings

Several different types of concrete coatings are available to protect a surface from contamination and weakening. Penetrating sealers provide an invisible layer of protection against temperature extremes and harsh chemicals. Acrylic sealers produce a thin film that protects the concrete apparent. Polyurethane concrete coatings are usually thicker and more long-lasting than ordinary sealers. Epoxy coatings are scratch-resistant and provide a colourful appearance. A concrete overlay may also be applied to restore a smooth finish to a surface.
Penetrating sealers are usually applied as an exterior concrete coating. This coating penetrates the surface to create a barrier against moisture chemicals. These sealers are transparent when applied and do not alter the natural appearance of the material. They also provide protection from freezing temperatures and sunlight. A penetrating sealer is easily applied and is one of the least expensive coatings for concrete.

 An acrylic sealer works at the surface to protect the material from damage. Acrylic concrete coatings can be applied to both interior and exterior surfaces and are available in an oil or water base. This sealer variant dries quickly and can be purchased in finishes ranging from glossy to matte. Acrylic sealers used on interior surfaces typically require frequent maintenance, however. This type of coating is relatively inexpensive and easy to apply.
