Atmospheric Rivers Cause Unintended Consequences to Roofs & Buildings

Posted by Nicole Gale on Tue, Feb 21, 2023 @ 08:19 PM
Atmospheric Rivers NCCThe U.S. West Coast has been hit with several atmospheric rivers lately. According to the National Oceanic and Atmospheric Administration, these atmospheric rivers "are relatively long, narrow regions in the atmosphere – like rivers in the sky – that transport most of the water vapor outside of the tropics. These columns of vapor move with the weather, carrying an amount of water vapor roughly equivalent to the average flow of water at the mouth of the Mississippi River. When the atmospheric rivers make landfall, they often release this water vapor in the form of rain or snow."

Too much sustained wind and rain in a short period of time can cause all sorts of water damage to buildings due to unresolved or unknown roofing and building envelope issues. The recent storms on the West Coast have done just that. Excessive amounts of water damage to buildings have been reported and contractors are experiencing large amounts of leak repair calls. They are being inundated with work and foresee this entire year being very busy resolving these issues. As the Earth continues to warm, climate scientists are predicting these storms to occur more frequently, bringing even more destruction.
How Can You Protect Yourself?
We can't stop Mother Nature but we can implement ways to protect our buildings and the assets inside of them. We recommend scheduling a roof inspection or doing one yourself. If you see damage, ponding water, clogged drains, blisters, dried out roofing material, tears, etc... You need to get these areas fixed as soon as possible. National Coatings' AcryShield Roof Management (ARM) System is an excellent waterproofing solution. This system can be applied directly over your aged and or failing roof without a costly or time consuming roof tear-off and replacement. These systems are also fluid applied over virtually any roofing substrate for a custom tailored, seamless, monolithic rooftop.

Seamless Coating Systems Are A Supreme Choice for Flat Roof Materials

Posted by Nicole Gale on Thu, Dec 11, 2014 @ 11:30 AM


There are many roofing materials on the market that offer different benefits; however, roof coating systems and spray polyurethane foam (SPF) roofing systems are able to provide a 100% monolithic and seamless membrane.

Download our  FREE Guide on SPF Roof  Coating SystemsThe benefits of a seamless coating system are quite simple. These flat roof materials have no joints, no seams, and no penetrations. This is beneficial because often times roof failures occur due to the lack of flexibility the roof membrane is able to provide over the years. As outside temperatures change from cold, to hot, back to cold during a single day, the building and roof expand and contract during those fluctuations. As your roof ages, it becomes brittle and loses it’s ability to remain flexible. So then as the building expands and contracts, the roof has a hard time keeping up with the movement causing a bulk of the tension to occur at the areas of joints, seams and penetrations. The isolated tension and deterioration of the roof causes these areas to ripe and tear, leading to water penetrating into the building. Seamless membranes are able to handle the additional stress from the temperature fluctuations as the tension is spread across the entire rooftop evenly.

Roof coating systems and SPF roofing systems not only have no seams or penetrations, but they have a built in added protection to prolong your roof life. The white reflective coating used in a roof coating system and on top of a SPF roofing system, reflects a majority of the sun’s heat away from the building, protecting the roof from the sun’s heat, which is the leading cause of roof deterioration that causes the roof to lose it’s flexibility.

The other very beneficial thing about seamless coating systems is its ability to be spray applied. Most flat roof materials are rolled out onto the rooftop and are cut into place, drilled and nailed down or welded around seams. This process is cumbersome as many roofs have multiple items on the rooftop that need to be properly cut around and sealed such as HVAC equipment, pipes, drains, etc… A spray applied roof membrane is simply applied around rooftop equipment just the same as it is on open areas of the roof – sprayed. This allows for ease of application, quick installation, and the ability to waterproof those hard to reach areas without any extra time or work.
