Enemies of Your Roof
A roof system's performance is affected by numerous factors. Knowing about
the following will help you make informed roof system buying decisions:
Sun: Heat and ultraviolet rays cause roofing materials to deteriorate
over time. Deterioration can occur faster on the sides facing west or south.
Rain: When water gets underneath shingles, shakes or other roofing
materials, it can work its way to the roof deck and cause the roof structure to
rot. Extra moisture encourages mildew and rot elsewhere in a house, including
walls, ceilings, insulation and electrical systems.
Wind: High winds can lift shingles' edges (or other roofing materials)
and force water and debris underneath them. Extremely high winds can cause
extensive damage.
Moss and algae: Moss can grow on moist wood shingles and shakes. Once it
grows, moss holds even more moisture to a roof system's surface, causing rot. In
addition, moss roots also can work their way into a wood deck and structure.
Algae also grows in damp, shaded areas on wood or asphalt shingle roof systems.
Besides creating a black-green stain, algae can retain moisture, causing rot and
deterioration. Trees and bushes should be trimmed away from homes and buildings
to eliminate damp, shaded areas, and gutters should be kept clean to ensure good
drainage.
Trees and leaves: Tree branches touching a roof will scratch and gouge
roofing materials when the branches are blown by the wind. Falling branches from
overhanging trees can damage, or even puncture, shingles and other roofing
materials. Leaves on a roof system's surface retain moisture and cause rot, and
leaves in the gutters block drainage.
Missing or torn shingles: The key to a roof system's effectiveness is
complete protection. When shingles are missing or torn off, a roof structure and
home or building interior are vulnerable to water damage and rot. The problem is
likely to spread-nearby shingles also are ripped easily or blown away. Missing
or torn shingles should be replaced as soon as possible.
Shingle deterioration: When shingles are old and worn out, they curl,
split and lose their waterproofing effectiveness. Weakened shingles easily are
blown off, torn or lifted by wind gusts. The end result is structural rot and
interior damage. A deteriorated roof system only gets worse with time-it should
be replaced as soon as possible.
Flashing deterioration: Many apparent roof leaks really are flashing
leaks. Without good, tight flashings around chimneys, vents, skylights and
wall/roof junctions, water can enter a home or building and cause damage to
walls, ceilings, insulation and electrical systems. Flashings should be checked
as part of a biannual roof inspection and gutter cleaning.
