Fix a Leaky Roof

Fast, Economical, and Resilient Solutions for Roof Leaks

When dealing with a leaky commercial roof, finding the right product that can be applied quickly, is imperative to preventing long-term damage to your building and equipment. Waiting too long will most likely cost you more, as uncontrolled moisture can damage your roof to the point where a full and costly replacement is necessary.


Step 1) Find the Cause

The first step in making an informed decision is to determine what caused the leak in the first place. Correcting the underlying cause and utilizing the product with the best compatibility for the job determine how effective your roof repairs will be. Not sure how to inspect your commercial roof? Contact a Topps Certified Installer to discover the causes for you.


Step 2) Compare Physical Features

Once the cause of the leak is determined, there are many physical properties that need to be taken into consideration when choosing the right repair sealant product. Multiple forces are often contributing to the problem. Since it is impossible to ever know which singular characteristic will prove most important to the durability of your roof system, the best roof sealant compounds should perform well for you on every count. Prioritize products with high levels of elasticity, tensile strength, and tear resistance among other things.
