 Should
I install new shingles over my existing
roof?
Gables
Roofing highly recommends the removal of
the old materials, allowing a
proffesional to inspect the existing
wood deck for any defects that can be
fixed. If the old materials are not
removed, they will not lay flat without
cracking or buckling and appearance will
ablso be a large factor. |
|
 What
causes ice dams?
A continuous thaw and re-freeze process
creates ice dams. During the winter when
heat from the attic warms the roof or
sun melting snow may cause ice dams.
Vapour barriers, insulations and proper
ventilation can help prevent these
problems. |
