Roof Problems |
 Leakage in attic after wind-driven rain. Possible cause: Leaky or
inadequate shingle underlayment or deteriorated flashing.

Possible cause: Inadequate
shingle underlayment allows water
from ice dams to leak into attic.
|

 Blistering and/or peeling of
interior and/or exterior paint.
Possible cause: Excessive
temperature or high humidity due
to poor attic ventilation.
|
|
 Stains on interior ceilings and
walls or mold and mildew growth.
Possible cause: Inadequate or
faulty shingle underlayment
allowing leakage or inadequate
ventilation.
|

| 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. |
