Holmes on Homes (2003)

Season 5: Episode 3

A photographer wants to build a photo studio in his backyard. He does everything by the book - has blueprints drawn up and approved and takes out construction permits and deals with puzzling stop work orders from various city officials. Only after the Mayor intervenes, is the work finally completed. Or so he thinks… Three years later, the studio's flat roof is plagued by constant leaks. Mike Holmes immediately identifies the problem - the waterproof roof membrane was never actually finished. The Holmes On Homes™ team discovers that the water damage to the flat roof is so extensive, they have no choice but to pull it all down!
