Hot Mop or Torch Flat Roof?
 
I have a flat roof with air conditioning duct work on the roof that is
leaking near the penetrations. I am going to have the roof torn off and
put on a new roof. Should I use torch or hot mop? Can you folks share
pros and cons of each. Thanks.

I don't know if this is available in your area but, I had both of my
flat roofs covered with fibre glass, this was some 24 years ago, its
still in perfect condition.
The best thing about fibre glass is that its easy to repair should it
ever go wrong.
Lots of boats and all sorts of things are made of fibre glass and some
have been afloat for 40 years or more.
Look it up.

Are your AC and heat bill high, look into Foam roofing, up to R 7 "

Membrane roofs are the most frequently used today, very durable, long
lasting.

Torch down is vastly superior to hot mop. The difference is the
price. Torch down is more costly, but does a better job for a
longer period of time.

In the past, the hot mop roof was the best thing going because it
could be applied over a large area and could be spot repaired
(meaning that if the leak could be located an area of the roof could
be redone). The problem is that it dries out and cracks and allows
water penetration that is difficult to locate and can cause severe
structural damage on wooden roof structures before you know it is
leaking. But it was cheap.

Torch down or modified roofing has evolved to the point that it is
fairly acceptable in terms of cost and lasts longer than built up
roofs. It can be repaired fairly easily. There are many varieties
of torch down out there and they vary widely in cost.

For my money, built up is going the way of wooden shingles and torch
down is the only option if I am forced to own a flat roof.

Add roof trusses and a regular pitched roof, with a little planning
the truss area can be used for storage or upgraded insulation:)


It hasn't been all that many years that the local Grade School was
reroofed exactly that way. Couple millions and they figured it would
pay back from not havign to re-roof and fight leaks all the time.

Jail is getting its second "gauranteed" not to leak flat roof done
again, it was done about 15 years ago. I worked there during it an
the same leaks were there afterward. Building was new in 1985 the
same year I started work there. Leaked from day one.
