New roof installed on the 3rd. Tamko architectural, single layer, 6ft of membrane, new vent stacks, new skylight, partial reuse of step flashing.
The roofer that did this job used copious amounts of silicone around the vent stacks, skylight, and along part of the flashing.
Granted I don’t know much about roofing, but a red flag triggered as soon as I saw this job. I am meeting with the roofer on Friday to review these concerns, and would like some insight from knowledgeable people to back up my claims.
The roofer claims the silicone around the skylight and vent stacks is to prevent ice damming. My understanding is that these items already have a membrane. What the silicone says to me is that the roofer doesn’t trust his workmanship.
I am also concerned about the silicone around the straight and step flashing. This seems unnecessary and seemingly poses a high risk of trapping water.
Any insight would greatly help and would definitely be appreciated.
