What we found
The inspection, in plain words.
Every finding came with photos and a clear rating, so the owners knew what had to be done now and what could wait.
Finding 01
Repair
Failed dormer step flashing
Water-tested section by section until the dormer flashing gave itself away.
Finding 02
Repair
Underlayment torn at the dormer
A small tear behind the flashing was carrying water into the wall cavity.
Finding 03
Watch
Main roof in good shape
About eight years of life left. No full replacement needed, despite two quotes saying otherwise.
Replace: worn out across the area · Repair: one fault letting water in · Watch: fine for now, checked again next year
Scope of work
What the price covered.
Section-by-section water test to find the source
Rebuilt step and counter flashing at the dormer
New underlayment around the dormer walls
Matched shingles worked back in by hand
Follow-up check after the next big storm

How it turned out.
A dry dormer, a roof with years of life left in it, and a repair that cost a fraction of a replacement.
