May 22, 2017
When the old skylight is removed, the need to flatten out the existing flashing on the top of the curb is common. We use roofing nails every 3 – 4 inches to ensure a flat surface on which to mount our new Velux skylight
The new skylight is installed and the pan flashing has been exposed. Debris build up is substantial and evidence of past, and perhaps current leakage, is evident in the form of stained 1x4 wooden cross straps
A bathroom fan is vented vertically, which is always a preferred installation over that of a horizontally ducted fan venting out the soffit, however in this case it was still a potential leak due to the hardware used, so we removed the old plastic attic space vent and installed a new galvanized gooseneck vent
Here’s another new skylight with yet another dirty pan flashing and another bathroom fan vent right beside it
A furnace vent stack was also near the leak area so we resolve an initial install deficiency on the flange of the vent. We site-bend a vertical lip on the two sides of the flange to act as a containment lip. It’s the exact same detail and strategy used around skylight curbs
Here is the 3rd new skylight we installed with the pan flashing exposed
A new gooseneck vent has been installed down by the corner of the skylight and the pan flashing has received our typical caulking treatment on the top side corners
There is fresh staining on 1x4 slats on this side of the skylight
Area completed. Another issue resolved through our work process was that of the usage of sliver tiles butting up to the skylight curb. There less-than-full-size tiles actually block off the pan flashing and provide the foundation for a dam of debris to build up. By eliminating these slivers we open the pan flashing up and allow a freer flowing of rain water. Lead cover pieces are used to span the weakness of where the full tile’s coverage is short. We have had ultimate success using this strategy.

This was a job in which we were called to because of a roof leak and our specialization in working on such projects. The unfortunate location of the leak provided little clue as far as the cause. There were several possibilities and likely suspects. We had to address all of them to be certain the leak was going to get fixed. When the customer learned we were also Velux Skylight Certified Installers he chose to upgrade his 3 old acrylic domed skylights to those of a sealed glass unit. It only made sense to do all the work at once. This skylight upgrade was not required to address the leak issue but was something the customer had been considering for some time. We were happy to oblige.
Our customer was so happy he voluntarily posted a very positive review on the home owner lobby website called Homestars.
