Chapter 2: Clogged Gutters & Basement Flooding
Moisture and Physical integrity
The exterior of your home is susceptible to damage from clogged gutters. The water will not overflow to the ground but typically overflows on to the fascia board (area that gutter is attached to) and rots out that area. Additional damage happens when water gets into the soffit area from holes in the fascia or from water draining and adhering to the soffit.
You may not see the damage until it's too late, such as soffit panels falling off, or the gutters breaking away from the home. Either way, these issues are very expensive to fix.
Bottom Line: Besides interior damage, clogged gutters can cause exterior damage to areas around the gutter system. Typically, this problem isn't apparent until extensive damage has been done.
