Roof Maintenance Program

On the first pan flashing we were working on we found a complete blockage. I don’t know how this one wasn’t leaking. Look at the amount of cementious powder built up at the top of the partial tile that is laying directly in the pan flashing!

Here it is all disassembled and cleaned with the exception of the black mastic someone applied in the center of the pan flashing where the complete blockage was. We will remove that also before we reassemble everything

Here is the 2nd skylight all disassembled and cleaned

and here is the 3rd skylight disassembled and ready for cleaning

The 3rd skylight had a design flaw in the pan flashing. The vertical upturn (containment lip) did not continue up the entire side of the pan flashing. It stopped short and would allow water to exit the pan flashing. This was a leak. See right where my finger is pointing.

We resolved this containment lip issue by building a wall in the pan flashing with caulking. Evidence of past leakage exists in the staining of the 1x4 wood just outside of the pan flashing.

This is skylight #1 where the black mastic was put down by a previous service man. It is now removed and the pan flashing is clear.

Instead of putting back those “sliver” tiles, that completely blocked the pan flashing, we modified it using lead pieces. It is 100% watertight and now has the enviable characteristic of possessing a spacious, and easy to flow, pan flashing.
