Roof Damage

The key to a roofs effectiveness is complete protection. When shingles are missing or torn off, the roof structure and the interior of the home are vulnerable to water damage and rot. And, the problem is likely to spread. nearby shingles are easily ripped or blown away. Missing or torn shingles should be replaced as soon as possible.

When water gets underneath the shingles, tile, metal or other roofing materials, it can work its way to the deck and cause the roof structure to rot. And, the extra moisture encourages mildew and rot elsewhere in the house, including damaged walls, ceilings, insulation and even the electrical.

Tree branches touching the roof will scratch and gouge the roof materials as they are blown back and forth by the wind. Falling branches from overhanging trees can damage or even puncture shingles and other roof materials. Leaves on the roof surface retain moisture and cause rot, and leaves in the gutters will block drainage.

High winds can lift the edges of shingles and force water and debris underneath them.

When shingles are old and worn out, they start to curl, split and lose their waterproofing effectiveness. Weakened shingles easily are blown off, torn or lifted by wind gusts. The end results are structural rot and interior damage. A deteriorated roof system only gets worse with time so it should be replaced as soon as possible.

This could be due to an active leak in the roof or to condensation caused by poor roof ventilation.​​

Moss can grow on shingles and other roofing materials if they are kept moist by poor sunlight conditions and bad drainage. Once it grows, moss holds even more moisture to the roof surface, causing rot, and its roots actually work its way into the deck causing deterioration. Algae also grows in damp, shaded areas on asphalt shingle roofs. Besides creating an ugly black-greenish stain, it can retain moisture, causing rot and deterioration. Trees and bushes should be trimmed away from the house to eliminate damp, shaded areas, and gutters should be kept clean to ensure good drainage.

Heat and ultraviolent rays cause roofing materials to deteriorate over time.
