Roofing Question [RE-wrenches]

[Bruce Leininger]

Hi Barbara.  Thank for taking the time to respond to my question.  I did
a product search at McMaster Carr and found the Butyl-Rubber Sealing
Tape, p/n 76385A15.  Is that the product you were referring to?  I've
also had experience with the SM5228 (Butyl) TACKY TAPE from
SCHNEE-MOREHEAD and found it easy to work with.  I wonder if that would
be a comparable product. 

I also had some questions about application.  Are you using this for
flat roof applications:  e.g. tar & gravel and modified bitumen?  Do you
just seal the stanchion to the roof, or do you also install a flashing
and seal that with the butyl tape as well?  If you do, do you just press
attach the flashing to the roof with the butyl rubber, or do you put
some nails in the flashing?

500+ systems with no leaks is an amazing record.  I'd like to make sure
I get the technique right. 

Thanks.
