There are several
key signals that you may have a problem with your pre-existing roofing system.
You may need to consider repairs or replacement if:
-
You notice leakage in your attic after
a wind-driven rain.
Possible cause: Leaky or inadequate shingle underlayment or deteriorated flashing.
-
You notice leakage in your attic after
an ice build-up.
Possible cause: Inadequate shingle underlayment
allows water from ice dams to leak into attic.
-
There are stains
on your interior ceilings and/or walls.
Possible cause: You either have inadequate/faulty shingle
underlayment allowing leakage from ice dams.
-
You notice decay
of roof shingles, sheathing, and/or siding.
Possible cause: Poor attic ventilation
-
You find missing,
cracked or curled shingles.
Possible cause: Shingles have reached the end of
their useful life into attic.
-
You see dark,
"dirty-looking" patches on your roof.
Possible cause: Environmental pollutants;
vegetation, fungus or algae; loss of granules due to age of shingles.
* In warm weather, inadequate ventilation will trap
hot air in the attic, causing air conditioning systems to work harder, or
leaving your home's interior hotter and less comfortable. Attic Ventilation: In
both hot and cold weather, insufficient attic ventilation may cause moisture in
the attic to become trapped and condense on the rafters. This condensed moisture
can drip down onto the insulation and reduce its effectiveness. Excessive energy
costs can result.
