White roofs exhibit two other advantages over darker roofs in addition to the savings in energy costs:
Cool roofs tend to last longer. The reason is
changing temperatures cause a roof to expand and contract. Since white roofs expand less in summer time, the roofing material is worn less
These roofs are "maintainable". As needed, a white, acrylic reroof can be recoated with additional white acrylic applications, which eliminates tearoff costs over the lifetime of a building

Commercial metal roof with ten year warranty against leakage
White commercial metal roofing has been accepted by business owners since the 1980s when acrylic first appeared in formulations for roof coating. Contractors, like myself, have long found these roofing surfaces natural candidates for acrylic/elastomeric related repairs.

Preventing rust on a self-storage project
Silver Film projects work best where rust is the primary problem. Silver Film, unlike its aluminum competition, carries a seven year warranty against any rust breakthrough.
Silver Film material is considerably less expensive compared to acrylic: Acrylic can weatherproof against leaks--Silver Film cannot. There is an old adage that "You get what you pay for." There is a lot of truth to that statement.

Cool roof on flat surface formerly covered with stones
A flat roof with stone is usually a costly project for a business owner--tearoff costs, stone removal, new insulation, etc. There is an alternative that results in a Cool Roof.
Since the 1980s we have worked on flat roofs covered with aggregate/stone offering the following advantages:
1. No tearoff costs since the basic roof is left
2. Removal of loose stone since the stone only prevented the roof's exposure to sunlight
3. Installation of a Cool Roof which is maintainable for the building's lifetime

Cool roof over Baltimore row house
Recently the heat island effects in large cities has become well known. We have participated in the earliest row house projects in Baltimore, cooperating with the city on a series of projects. In 2007, the Civic Works organization, located in the Clifton Mansion, has begun to apply Cool Roofs to row houses.

Vintage metal roof converted to Cool Roofing
Most vintage metal panel roofing owners prefer the tinted acrylic colors, such as Barn Red or Restoration Green. On occasion, a white surface makes sense.
