A built-in roof / gutter downspout installed in two pieces in the interior of a roof deck. As leaves and debris built up in the lower bend of the downspout, rain water was forced back and out of the seam in the downspout, destroying the ceiling, rafters and structure.

A shingle roof installed with NO flashing. Rain water was running right through the crack at the wall and soaking the roof decking.

Sandstone window sill broken by roofing contractor trying to secure flashing with expanding pin fastener. 

No step flashing, a one piece surface mounted counter flashing / flashing design with metal flanges that are spread out over the shingles and everthing is tarred/cemented in place.

Roof shingle nails placed too high and over driven by the roofing contractor results in the shingles sliding and blowing off the roof in high winds. Roof shingles fastened in this way are not covered by the manufacturers warranty.

Chimney flashing set into a thin saw cut in the brick mortar allows for very little room for the caulking. And after only 7 years, this thin bead of caulking is dried out, brittle and allowing water to seep into and behind the chimney flashing.

Single ply modified roofing membrane glued directly to roof boards. What should have been a simple roof removal has turned into a  significantly more time consuming and consequently, a much more expensive roof job for the current home owner.
