Poor Ventilation
The temperature of attic spaces should be very
close to that of the outside air temperature. If the attic is overly warm in the
winter, ice and snow melts too quickly and then re-freezes at the roofs eve.
This causes ice damming. If the attic is too hot in the summer, it can cause
curling and clawing of asphalt shingles. Proper attic ventilation prevents these
problems by allowing for proper air flow and essential circulation.
Poor Workmanship
The proper installation of any type of roof
requires a combination of skill and attention to detail. Many times,
problems that are not apparent until months after a roof is completed are a
result of contractors rushing through a job, and not taking the time to do the
details right.
Hasty Repairs
Often repairs are made in haste without
identifying the true source of the leak. This often requires a more
complex fix than would have been required.
