It helps to distinguish condensation from actual ingress. Persistent moisture at one window, especially after rain or wind, suggests an envelope issue; moisture that appears mainly during cold weather may point more toward indoor humidity or thermal bridging.
How water enters
Water ingress is usually the result of more than one small defect. Roof-to-wall intersections, window perimeters, foundations, drainage failures, and poorly integrated flashing can all create paths for water to enter a building.
The key idea is that buildings shed water in layers, like shingles. If those layers are reversed, interrupted, or poorly sealed, water can be directed inward instead of outward.
Inspection priorities
For portfolios, use a standard checklist so reports are comparable across buildings.
That checklist should cover:
- Roof surface condition
- Drains and gutters
- Flashing
- Rooftop equipment
- Window seals
- Sill drainage
- Interior staining
- Exterior signs of runoff or ponding
