WHAT TO WATCH FOR

Rust staining, cracking and loose fragments can occur together. Spalling at elevated edges or overhead areas needs prompt attention because detached material can fall.

WHY A SURFACE PATCH MAY FAIL

A patch can hide the symptom while corrosion, unsound material or water entry remains. The depth and extent of deterioration determine the appropriate repair.

THE NEXT STEP

Document the location without entering an unsafe area. Ask a qualified restoration professional about investigation and involve a licensed engineer when structural deterioration is suspected.
