How water reaches the vigas
- Roof leaks above that land on a viga and travel along it
- Gaps where vigas pass through walls
- Exposed viga ends outside that crack and draw water in
- Parapet leaks that follow the viga pocket
Why it matters
Vigas carry the roof. Long-term moisture can rot them, especially at the ends inside the wall. Catching leaks early protects the structure.
Fixes
Seal the roof or parapet above, seal around vigas at the wall, protect exposed ends, and have soft wood checked. See viga and ceiling leak repair.
Common questions
Should exposed viga ends be capped?
Capping or sealing exposed ends helps protect them from sun and water.
