Q Our satellite dish installer simply set the dish on top of the
roof and screwed it down through the shingles. Will the roof
leak now?

A We checked with several roofers and satellite dish companies and they all
said the same thing - you shouldn't have a leaky roof. Installers typically
take precautions against leaks by applying a silicone sealant to the holes when
inserting the fasteners. If they later remove a dish, they fill the holes with
sealant.
However, it's possible that wind could loosen the dish slightly and cause a
small leak. If you see a water stain on the ceiling, apply a bead of sealant around
screw heads and around the flanges on the dish using an exterior-grade
polyurethane or silicone sealant.
