Problem
What needed attention
A Richmond-style rear addition with low-slope membrane shows ponding at a drain, blistered torch-on seams, and cracked transitions at the wall edge.
Diagnosis
Assessment focus
Ponding and failed seams at drainage and wall transitions are classic low-slope leak points. Scope is membrane patching at the failure zones, not a full building reroof.
Solution path
How work is framed
Patched SBS membrane, a dry drain area, heat-welded overlaps, and an intact wall transition with the main house unchanged.
