I just replaced one of the roof vents on my '88 Grandby and have a couple questions before I call it done.
The holes on the new vent didn't line up so before I drilled new ones I silicon-ed over all the old holes. Put the Butyl tape on the underside of the vent frame and used metal roofing screws -the ones with rubber gaskets- instead of the sheet metal screws supplied.
As you can see in the pic, the butyl squeezes out in some spots, but in the areas of lower elevation in the ribbing of the roof, it doesn't. Should I be concerned about this? Should I remove the excess butyl and seal entire perimeter of vent with some caulk style sealant? If so, recommendations?
I would rather deal with it's now as it dry, cleaned with a wire wheel, and my shop is currently empty!
Thanks for the advice.
