How Much Live Load or Weight Can a Commercial Flat Roof Withstand?

There is a lot of controversy about how much load a flat roof can hold and whether or not that might have to be re-evaluated regarding manufacturing practices, to account for larger loads of snow during heavy winters. The issue is that, even though most roofs are able to hold about 20 pounds of weight per square foot, there is a huge difference between light snow and amounts of snow built up over time.

Light snow that falls after a night of snowing can weigh about 3 lbs per square foot. This is not nearly enough to cause any kind of damage to your roof, and even if the snow persists for several days, that value is not usually likely to increase past about 5 lbs per square foot. However, as the freeze sets in while seasonal blizzards come and go, and if business owners fail to clear the snow on a regular basis, the snow on the bottom can turn to ice due to the lower temperatures and higher pressure caused by additional falling snow.

As it turns out, the kinds of blizzards that are strong enough to bring that much snow and the kind of climate that can actually put a dent in your flat roof might be very rare indeed, as even ten inches of fresh snow won’t go far beyond the 5 lbs/sq.ft. mark.San Antonio roofing companies

However, over time, pooling can form when large concentrations of snow are gathered in one place. The good news is that Texas rarely has extreme colder and snowy weather. However, professional San Antonio roofing companies confirm that regardless of where your business is located, it’s still a good idea to install a dependable and durable flat roof, and clean and maintain your roof on a regular basis throughout the year.

Why Does the Quality of Epoxy Matter When Waterproofing a Roof?

Image
When waterproofing your roof, you have a few great options that you can consider, including elastomeric and epoxy coating. The importance of using the highest quality material you can get your hands on cannot be stated enough, since the future condition of your roof will depend on the level of quality that the waterproofing material actually has. In the case of epoxy, we’re talking about a two-component resin that has all the regular attributes of an epoxy compound. That means it’s very good at resisting water once it hardens, and it becomes very tough, while sticking to the surface it was designed for better than most types of resins. Because it’s applied as a liquid, however, it means that there’s only one try to get the mixture just right and to apply it correctly to the roof. Any mishaps or the use of a lower quality compound will definitely show, not just in the appearance of the material, but in its ability to protect your roof from rain as well. While proper application is e...

Types of Metals Used in Metal Roof Installation

Image
Metal has been around in the roofing industry for quite some time, and there is a huge variety of options to choose from, depending on the specific needs and budget for your project. For instance, copper lasts for a very long time and can be molded easily at high temperature, so it is a good option for a metal roof installation. In fact, a properly maintained copper roof can last for about 200 years. At the same time, copper roofs are 100% recyclable. Steel can come in three variants, such as galvanized steel, weathering steel and galvalume. Another great thing about steel is that it is one of the most recycled element on earth, and roofing makes no exception, so it is the best choice for those who want to be environmentally-conscious. Zinc is also very long-lasting and corrosion resistant, while also having a very low melting point. Another great material for roofing systems is aluminum. It lasts for a very long time and can withstand salt water corrosion. Due to this fact, alumin...

What Is an Elastomeric Coating and Why Would You Consider It?

Image
There are a number of different types of coatings that can be applied to roofing surfaces in order to protect them from bad weather. Elastomeric coating is considered to be one of the most efficient. Designed for application on surfaces such as roofs and masonry wall surfaces to protect from bad weather, increase energy efficiency and prevent leaks, elastomeric coating is a type of coating made from a stretchy material that is typically highly resilient and up to 10 times thicker than most types of paint. Elastomeric coatings can last anything from 10 to 20 years, and are considered to be highly durable and efficient at what they’re designed for. Respected New Braunfels roofing companies confirm that you can get them for a variety of different types of roofs, and they can be adapted to weatherproof your roof, protect it from specific stressors or even keep your roof and your home cool in warm weather. Although it’s not too difficult to apply, and the price of elastomeric coating can ...
