IT'S THE FLASHINGS!
Believe it or not, this skylight is done according to the guidelines of the Tile Roofing Institute and the manufacturer's instructions. If the skylight contractor is going by code, he's falling short. That is why you are calling for repairs today.
The rain water is being channeled under the tile, onto the tar paper, causing premature wear and eventually ruining the roof in the area.
What most people find hard to believe is that the guidelines put out by the Tile Roofing Institute & the tile manufacturers, have flaws in them.
If the guidelines of the industry are so incredibly flawed, no wonder the average contractor, roofer or skylight installer is confused about proper roofing and flashing techniques.
We surpass the national standards and techniques used by our competitors by far.
