Chimney flashing plus "hot mopping"?


I was looking at an estimate to install flashing on my chimney. The price was a bit higher that I expected. The contractor tells me that he adds "hot mops" around the chimney and then installs the flashing on top. Does this make sense to any of you?. I have read some tutorials online where "tape" is used to prevent water leaks around the chimney. Is hot mopping recommended or will "tape" be sufficient to prevent water leaks when installing flashing?

Pictures would be helpful. Flat roof? Steep? Shingles? Slate? Never heard of a tape for flashing.

TF tape is a good idea behind flashing if installed properly, but should not be considered a seal by itself. It is more of a second line of defense in case any water makes it's way past the counterflashing. Sinse your contractor is talking about "hot mops", I assume this is a flat asphalt or bitumin roof. With the good quality cold asphalt products available today, I'm surprised anyone would still hot in a small flashing job. We really need to know if this is a flat roof and/or what material was used on the roof.

The roof is asphalt shingles. The shimney is located on the rear slope of the house. This would be called an "inside" chimney, since is its surrounded by house. The slope may be 25 to 35 degrees possibly. I don't have any pictures at hand but I will post one soon.

Chimney flashing plus "hot mopping"?


Ok, yesterday I jumped into the attic and had a chance to inspect the chimney under the roof. I did inspect for any cracks or leaks between the roof and the chimney but found none. It was a sunny day, I turned of my flashlight and inspected for any sources of sunlight around the chimney but found nothing. I am not sure where the possible leak that made a water spot damage on the drywall came from. Before I moved in there was not chimney cap.. could this be a possibility for the water damage on the drywall?. The water damage is about 6' over the floor level therefore even without the cap I believe it would be unlikely for water to filter through the brick and into the drywall. What do you think?. I may have to get an inspection by a chimney expert.
