Water-Shedding vs. Water-Resistant Roofs: How They Differ

Larry Walty II • February 9, 2021

As every homeowner knows, water is the number one enemy of roofing systems. After all, if water penetrates your roof, it can cause leaks and compromise the roofing system’s structural integrity. As such, plenty of roofing manufacturers have created roofs that can combat the problem that water causes. However, what some homeowners fail to realize is that there are actually different kinds of these roofing systems: water-shedding and water-resistant.

Here’s what you need to know about them, according to residential and commercial roof repair expert Larry Walty Roofing:

Water-Shedding Roofs

Water-shedding roofs, or hydrokinetic roofing systems, are often used on roofs with a slope that’s 3:12 or greater, and will usually rely on a secondary membrane to prevent water from entering the building. According to experts, if you have a water-shedding roof, it’ll shed water off the roof and into the gutters much faster. If you want a water-shedding roof, you’ll have to install a solid deck that’s covered with a moisture barrier or membrane that’s at #30 felt. As much as possible, roofing pros also recommend that you avoid intricate trim details and roof profiles as every non-continuous point on the roof can leave it vulnerable to leaks.

To install a quality water-shedding roof on your home, don’t hesitate to approach the roof repair and replacement pros of Larry Walty Roofing for assistance.

Water-Resistant Roofs

On the other hand, water-resistant, or hydrostatic roofs, are a necessity for roofs with a slope that’s 3:12 or less and require the use of various techniques to block moisture out and seal your roof against water. Unlike water-shedding roofs, water-resistant roofing systems do not need to rely on a secondary membrane to prevent leaks from occurring. When installing a water-resistant roof, the best approach is often to opt for a roof design with seams that are at least two inches high. That way, the roofing system can move with thermal expansion and contraction without any damage. Avoiding the use of exposed fasteners can also help create a water-resistant roofing system for your building.
