How to take old silicone off roofs.

Removing and replacing old silicone sealant that has become dirty or discoloured can really freshen up your bathroom. To release the silicone from its tube you ll need to cut the end of the nozzle with a sharp knife. If you have to remove it silicone roof coatings are stubborn. If the sealant and the roof are clean you should be able to apply a new one easily.

Over time silicone tends to retract from roofing edges and contract into a curl. On the other hand a caked and hard to remove old sealant means that you can just leave it be.

Apply heat with a hot air gun if the silicone does not come off easily with the razor. Its an easy job that you can do at home. Get a roofer or someone who knows how to pull off a few shingles and replace them. This means exposed roofing substrates that are no longer waterproof or moisture proof.

As long as the existing substrate is stable and dry then there is no requirements to remove the existing roof unless there is another silicone product already in place that is incompatible with the membrane. Set the hot air gun to a high heat setting and point the nozzle at the trouble area. If you wish to apply a thick silicone bead cut further up the nozzle to create a wider hole.
