It has been a number of years since I did this kind of work but its sounds
like a poor fit was 'doped' with a lot of asphalt. The metal flashing is
supposed to do the bulk of the work with a little along the top edgewhere it
should be up to/ under a flange along the edge of the light. This flnge is
supposed to do the deflecting of the water and the asphalt just stops any
backwash in a storm.

Last week, I had my house re-roofed, and they seem to have done a good
job.
As part of the work, they replaced a skylight. In the room where the
skylight is, there is a smell of roofing cement. Actually, the smell
travels
throughout the house because it gets picked up in the air conditioning
system, but is strongest near the skylight and especially in the heat of
the
day.



I went up on the roof to take a look, and noticed that there is roofing
cement on the place where the skylight fits onto the sheathing/frame. In
other words, they put roofing cement on the plastic itself where it
contacts
the metal sheathing/frame. The skylight seems to be nailed in properly,
and
nothing leaks.



I assume that the sun is heating up the roofing cement and the smell is
coming downward from the skylight. Which leads me to my two questions:



First, is putting roofing cement where they put it, as I described above,
the right thing to do? Though I have no experience here I would think that
nailing it in is enough, and that putting roofing cement where they did
would make it difficult to remove the plastic if ever necessary. Second,
will this smell go away over time?



Thanks,





Ross
