Damage to your roof can be caused by a number of factors,
many of which can be prevented or controlled. Listed are a few of the more
common causes of roof damage. Be sure to get a copy of our "Homeowners
Guide to Knowing When It's Time For A New Roof" which includes a
comprehensive checklist of things to look for and how to spot damaged spots.
• Ventilation - is
important; without it, heat and moisture may build up and cause rot in the
sheathing or rafters which then causes shingles to buckle and insulation to
become ineffective.
• Adequate Insulation
- will protect the house from heat loss.
• Sun and Ultraviolet
Rays - cause different deterioration rates to different materials.
• Rain - can seep in
and cause structural rot, moisture can cause mildew inside and out.
• Wind - can lift
shingles allowing water to get in.
• Snow & Ice -
can cause backup and seepage into the interior of the roof.
• Condensation -
promotes the decay of wood in attic.
• Moss & Algae - can
lead to rot, creates stains, can be hard to clean, etc.
• Trees & Debris
- can gouge or tear shingles, or can retain moisture which can lead to rot.
• Missing or Torn Shingles
– causes leaks, and weakness can spread to nearby areas and progress quickly.
• Shingle
deterioration - worn, curled or torn shingles lose their waterproofing
effectiveness, or can be easily blown off.
