Repair Supplies
Here are the products I use, and write about, on this website.  I only use the best products so that I don't have to go back and fix my customers' problems for free later on.  You can buy some cheaper stuff just to save a couple dollars in the front end, but think of all your valuable items that could be damaged, or costly repairs you'll have to make if your roof leaks.  It's better to buy the good stuff from this website.

Roof Repair Commercial Grade Polyurethane Caulking
!
Do It Yourself Roof Repair Commercial Grade Caulk

This is the "black caulk" that I use for roof PVC pipe boots, brick counterflashing, and skylights (for HVAC pipes, use tripolymer caulk listed below).  One tube of sealant should do 5 or 6 pipe jacks and each tube should seal approx. 8 to 12 linear feet of counterflashing on brick.  If you are unsure of how much to buy, or if you are more liberal in your application of the caulk, it would be better to get more caulk in the beginning of the project so you don't run out.
