If your roof is having problems, you have two options: rip off your existing roof and install a new one or lay your new roof down on top of your old roof. In some cases, it’s best to add another layer to your flat roof, but not always. Here’s what you should know. 

What Is a Flat Roof?

A flat roof actually isn’t entirely flat, but it’s close. A “flat roof” is installed on a very subtle angle so that it appears flat but actually contains a slight slope. This slope allows rainwater to drain off the roof. It is for this reason that a flat roof is also often known as a low-slope roof. 

How much thought do you give to the roof over your head? Probably not much, but the roof used to build your home influences how it handles rain water, snow, wind, and many other outside factors. Make sure you understand how construction differs with a flat roof so that you can make the best informed decision.

While flat roofs are becoming more popular among homeowners, they have long been preferred for industrial buildings. A flat roof gives you a place to put rooftop AC units and other building elements. A flat roof is also easier to access for maintenance on these systems.

But what material is used for flat roofs? You might think that shingles are inappropriate, but they are one of your more affordable options. However, there are many more durable and easier to maintain options.

PVC Membrane

This is the most commonly used roofing material for flat industrial roofs. It is durable, lasting up to 30 years, with little to no maintenance required. PVC membranes are also lighter weight and more flexible, making it useful for complex applications.

Even though you might be able to find a roofer that does both, there are very big differences between commercial roofing and residential roofing. Depending on which service you need, it is important to make sure that you hire a contractor with a clear understanding of the differences in pitch, materials, and installation. Here’s what you need to know.

Differences in Pitch

Homes are designed to be aesthetically pleasing, not just functional. That’s one reason why they require so much regular maintenance. Because homes come in so many different shapes and sizes, so too do roofs. Most residential roofs are very steep, while commercial roofs are mostly flat or very nearly so. Commercial roofs need to be flat to accommodate equipment and the like.

Commercial roof leaks are much more complex than residential roofing. While damage can certainly cause leaking in commercial roofs as well, there could be some other causes of frequent roof leaks on your commercial property. Here are some of the most common causes of roof leaks on commercial buildings.

Poor or no drainage

When your commercial roof was first installed, the contractors should have considered adequate drainage of the roof. Your roof is going to get a lot of water, especially during the rainy season. To eliminate leaks and expensive repairs, drainage systems must be installed. If your original contractor didn’t do their job properly or if the drain has become worn or damaged, it could cause leaks.

You know your roof protects your home from the elements and adds aesthetic value to your home, but do you really understand the role your roof plays in your family’s safety and comfort? In fact, your roof plays two important roles beyond protecting your home from water and storm damage.

Protecting your family from critters

Having a cat is a great way to keep small critters cleaned out of your home, but if you don’t have one available, your roof can be a great barrier to stop them from getting in to begin with. A well installed and sealed roof will take away access points for mice, squirrels, and even birds.
