Leaks are dangerous to both the structure of your roof and to the items located in your building. When leaks are left untreated, they tend to increase in size until items within the building are destroyed and the whole structure of the roof is compromised. Luckily, it is fairly easy to fill these cracks and to protect your roof from further damage. The way to protect your concrete roof is to place a concrete sealer on top of it. Concrete sealers are made up of special plastic and rubber coatings that attach to the concrete, creating a waterproof membrane that stretches with the concrete.
