RoofLock: RoofLock is a "Cross Linking Polymer," sealant. This continuous film cross-linking polymer coating can be applied over roofing shingles to form a protective barrier from mother natures most damaging elements.

Protecting your roof from UV rays, acid rain and mold forming algae will keep your home looking clean and beautiful. RoofLock also keeps the granules on your shingles in place by providing a waterproof seal. This seals out wind, ice and other damaging forces. RoofLock is guaranteed to add years to the life of your roof and keep it looking good.

US Roof Sealant, makers of RoofLock, provides the next generation of exterior coatings. We go beyond today’s sealants with a high tech system designed to provide a healthy environment for the consumer as well as being earth friendly. The areas we focus on are durability, mold and mildew prevention, ease of application, appearance, and value.

RoofLock is based on the benefits derived from cross-linking the highest quality materials, to manufacture the most durable products. Cross-linked polymerization increases the molecular weight, by the resulting formation of a three dimensional molecule - from the entanglement of the chain polymers reacting with each other.

US Roof Sealant goes beyond this to cross-link the coatings with the substrate to form a continuous film. It is like wrapping the surface in saran wrap to protect it, but beyond that, the coating actually becomes part of the surface to which it is applied. This continuous film technology is the only ambient temperature cross- linking process on the market today that is air, UV and moisture cured.

When environmental conditions are right for algae development, the problem rapidly expands, covering an entire roof. Once algae is present in an area, airborne spores are carried from rooftop to rooftop, infesting whole neighborhoods. All roof types, including wooden shakes, clay tile and asphalt shingles are susceptible to algae infestation.

Black staining is caused by the growth of algae and fungus spores that land on your roof, (Staining is not caused by pollution, soot or jet exhaust). These spores need three things to grow: heat, moisture and some kind of nutrient. The nutrient comes from dirt and the shingle itself, primarily the limestone filler used in manufacturing the granules.

The more the moss or algae grows the more moisture it will hold, keeping the roofs surface wet which, in turn, causes rot. Its roots work their way through the shingles and into the wooden decking causing tremendous damage. A maintenance tactic is to be sure and trim any tree branches that are shading the roof.

Shingle roofs are manufactured with different degrees of quality. Pricing is one way to tell the quality of a roof and the manufacturer's warranty is another. Most roofs applied by builders and roofing contractors are in the low to medium quality range. Higher quality roofs are generally found on expensive custom homes and where the owner has taken a special interest in the quality of the roof.

In the past, the only way to get rid of these stains was to re-roof the house. It is estimated that over 50% of all new roofs installed are due to the appearance of the roof and not to its functionality.
