we need to extend a pvc vent pipe from an attic space and through the roof. would require some shingle repair, flashing, jack etc. Is this something Brinkmann can do?

We would be more than happy to coordinate with the plumber to install a roof plumbing flashing.  We would need to know the size of the pvc pipe flashing as well as the type and color of shingles. If you do not know the type and color of shingles we can determine this with an onsite inspection.  Just call the at 281-480-7663 and communicated the information about the roof repairs.
