Caulks and sealants are products commonly used by homeowners and roofing contractors for their projects. These materials are often mistaken as being the same thing because they have similar purposes and even the same applicator. They are used to cover gaps between areas of buildings. Without proper use, especially on areas like the roof, it can cause leaks that can damage your home.
To better understand which product you should be using for your intended purpose, Neumann Construction answers some commonly asked questions about caulks and sealants.
What’s the Difference Between Caulks and Sealants?
Caulk hardens when it dries so it is best used in areas with less contraction and expansion. It has limited elasticity so it is more prone to cracking in regions with fluctuating temperatures. This material has fair to poor adhesion and will likely split or chalk within a few years. Meanwhile, sealants are made from flexible materials, making them more efficient in construction application like roofing. They may be more expensive, but they last longer than caulks.
Which Types of Sealant Are Best for Roofing?
If you’re working on a roof replacement project, then you might consider silicone and urethane sealants, which provide better results than caulk. Silicone sealants go well with different colors of buildings as they are translucent or clear, and can also be pigmented. Polyurethane is popular among contractors as it has good adhesion on various surfaces and features more flexibility than its contemporaries.
Which Material Lasts Longer?
The longevity of either is the same as the other elements on your roof, which, at some point, will have to be repaired. You might want to do routine checks to see if they need replacement. In any case, invest in quality. Choosing an inferior product and a low-cost contractor with poor workmanship can cost you more in the long run. No matter how expensive your sealant is, with wrong application, you won’t get a long-lasting product.
