SILICONE AND CONTINUED ROOF LEAKS – NOT A COMPATIBLE MATCH


February 28, 2018

When having a contractor evaluate your roof or when doing the work yourself, there are many things to look for. One of the most often overlooked problems is determining what the product is that was used to patch or coat the roof previously. Silicone is often used to glob fasteners or even to coat the entire roof itself. Most products can be cleaned and applied over when dry. Silicone, on the other hand, must be completely removed as nothing will bond to it. Before applying any product over suspected silicone, you should apply a test patch to check for adhesion.

When a silicone repair fails, it must be completely removed, as well as the residue it leaves behind. That may mean grinding it off of a metal roof, or scraping it off of other substrates. Once that’s done, use a 100% rubber repair compound, such as Topps Polyprene®. That will get the job done right, the repair will be long-lasting and you won’t continue to experience call-backs.

SKYLIGHT LEAKS


February 28, 2017

Determining whether the skylight is leaking or if there is a condensation problem should be evaluated by an expert. Condensation forms on the inside of skylights during high humidity and sharp temperature variation conditions. This condition can occur as the humidity in your building rises or during a rain storm. You would be surprised how much condensation forms on skylights when cold rain hits them. You may need to replace the skylights or replace with metal panels and insulation to alleviate the problem.

If it is merely a skylight leak (and not condensation), it is relatively easy to stop those leaks. Building movement often loosens the flashing and fasteners that once sealed the skylights when they were new. This creates space for water to penetrate and leak through your skylight. Resealing this area with a premium rubber flashing cement, such as Topps Polyprene, in conjunction with our polyester membrane, PolyCore, will stop the flow of water into the building.

If the skylights themselves are starting to weather, our maintenance clear liquid rubber SkyCoat™ can be applied to rejuvenate the panels.
