Detecting Water Damage Behind Exterior Siding
Water intrusion behind siding is one of the most destructive hidden home issues in New England.
Primary Causes of Water Intrusion
- Missing Kick-Out Flashing: Rain running down roof sidewalls funnels behind siding where the roof overhang meets the wall.
- Untaped House Wrap Seams: Wind-driven rain penetrates unsealed house wrap laps.
- Improper Window Sill Pan Flashing: Water leaking around window trim trickles into wall cavities beneath sills.
