These products have
stood the test of time and are backed by exceptional
factory warranties. There are less expensive roofing
materials that would provide a higher profit margin
but would tend to curl in as little as 3-5 years.
That is certainly not the type product we promote
among our customers.
IMPORTANT
ROOFING RELATED DETAILS
While
the selection of contractors and materials
is very important, so is attention to some
important related details. Before a new roof
is installed the following items should be
inspected and, if necessary repaired or replaced:
-
The chimney and chimney flashing
-
Skylights
-
Gutters, down spouts and
drains
-
Roof vents including vents
for various fans and kitchen hoods
-
The siding at dormers
-
Overhanging tree limbs
-
The electrical strike and
wires
-
Insulation in roof structures
without an attic access
Repair
or replacement of these items is usually
easier before or during the roofing process.
