How to take old silicone off roofs.

Clean the old sealant if need be. This means exposed roofing substrates that are no longer waterproof or moisture proof. Removing and replacing old silicone sealant that has become dirty or discoloured can really freshen up your bathroom. Then you should be able to seal right over the old one without any problem.

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. Scrape away as much of the old caulk as you can with a sharp razor blade. Over time silicone tends to retract from roofing edges and contract into a curl. Apply a bead of silicone.

Ponding doesn t matter when it comes to silicone roof coatings. 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. To release the silicone from its tube you ll need to cut the end of the nozzle with a sharp knife.

If this happened in an area of high visibility and the roof is more than a few years old and matching the shingles isn t perfect have the person doing the repair take a few shingles off the roof from an inconspicuous area. Scrape until the majority of the sealant is gone. Set the hot air gun to a high heat setting and point the nozzle at the trouble area. After a few moments test the area with the scraper to see if it has softened enough for you to continue.

Push the razor away from you being careful not to scratch into the finish on the metal. If the sealant and the roof are clean you should be able to apply a new one easily. If you wish to apply a thick silicone bead cut further up the nozzle to create a wider hole. If you have to remove it silicone roof coatings are stubborn.

Step 2 wet the area thoroughly and scrub with a nylon dish scrubber or medium bristle brush. Get a roofer or someone who knows how to pull off a few shingles and replace them.
