What we found
550 Vernon’s roof was at the natural end of its membrane life — bubbling in spots, several visible cracks, and signs of trapped moisture under the surface. The owner had been catching leaks in the top floor with patches for several seasons. Patching had run its course.
The other thing we found, which the owner was not initially focused on but which mattered just as much: the parapet flashing was a generation old and not properly tied into the roof membrane. That junction is where most “leaks in the top floor” actually originate, even when the roof itself is sound.
The Work
We tore off the failed membrane back to sound deck. Replaced a few areas of decking that had begun to soften. Installed cant strips at the parapet. Laid new modified bitumen with proper flashing detail at every parapet, drain, and penetration. Cleared and tested the drains.
The parapet-to-membrane junction got special attention — that is where future failure would have started.
The result
A clean roof with a 20–25 year service life ahead of it, properly drained, with the parapet flashing detail that should keep the upper rooms dry through any storm.
