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.
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 todays
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
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
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 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.
