Question
& Answers...
Q.
How long should I expect my roof to last?
A. All roofs eventually wear out; how quickly
depends on several factors, including: pitch of the roof,
quality of materials, quality of installation, quality of
attic and roof ventilation and the climate in your area.
Q.
What causes a roof to wear out?
A. Several factors combine to affect roof
deterioration. These may include ultraviolet radiation
from the sun; temperature or temperature extremes in your
area; inadequate ventilation; exposure to wind, snow, ice
and rain; and foot traffic on the roof. Darker color
shingles may have shorter service lives than shingles of a
light color.
Q.
What causes wood roof shingles to split and crack?
A. Splitting and cracking of the wood occurs
naturally as part of the aging process, largely due to
shrinking and swelling caused by moisture and subsequent
drying.
Q.
Can an existing roof be covered with another?
A. In areas prone to heavy snowfall, strong winds
or hail, or when an existing roof is wood or tile, overlay
may not be appropriate. In some localities, when a
composition roof is replaced, the roofer may not be able
to apply the new material directly on the old layer,
depending on its condition.
Multiple roofing layers
tend to decrease a roof's resistance to hail. Check your
local building codes before overlaying an existing roof
covering. Some building codes and ordinances restrict the
number of roofing layers a house may have.
Q. Can
composition shingles be repaired?
A. Yes. If damage is minor, a reputable roofing
contractor may be able to remove individual shingles and
replace them with new shingles.
Q. Is
financing available?
A. Yes, up to 100% with approved credit.
