There are a number of different types or roofing options that you can consider for flat roof commercial and residential buildings. When you are choosing the type of membrane or coating that you will be using, it’s a good idea to know what each of them is able to offer so you can make the right choice. Let’s look at some of the various choices that are out there.
Built Up Membranes
These types of roof coatings are made of felt that’s been impregnated with asphalt and then embedded in bitumen. They tend to be thick (although the thickness can vary). On top of the membrane, the roofers will place crushed stone or some other aggregate, which can help to protect it from wear and from damage caused by the sun. While this can be durable, it tends to be heavy, and it might not be the right choice for all roofs out there.
This is a type of rubber roof coating that is applied in sheets. The thickness of the sheets can vary – between 0.030 and 0.120 inches thick. At the seams, they are joined by an adhesive. These types of coatings are feasible in some cases, but it is important to remember that they have some drawbacks. Namely, they are vulnerable to UV rays from the sun, so they need to have a protective layer added to them. They can also be vulnerable to oxidizing chemicals and aromatic solvents. In addition, if the adhesive is not applied properly, it could create a gap. Water could seep into the gap and then get into the roof.
Vinyl or PVC
Another rubber roof coating is vinyl or PVC. This is an affordable option, and the sheets are put together with hot air welding, or solvent welding in most cases. Again, they are vulnerable to UV rays, as well as coal tar and petroleum based products.
Liquid Rubber Roof Coatings
One of the best and most reliable methods of protecting your flat roof, whether it is a commercial building or a residential building, such as an apartment complex, is Liquid Rubber. The coating goes on easily, like paint, and that means that there are no seams to worry about. It is able to stand up to temperature extremes at both ends of the thermometer, and it is waterproof from the moment that you apply it. It is a cost effective product as well. It only needs to have a single coat, and it is easy enough to apply that you could likely do it on your own if you have the time. As mentioned, it goes on just like paint. When applied correctly, it can last for decades.
While there are many different types of roofing options, including rubber roof coatings, you need to think about what’s right for your building and your budget. The liquid rubber roof coatings tend to be the smart option for those who are looking to save money, time, and frustration.
