recoated

The thing with flat commercial rooftops is that they take a beating over the years. The freezing ice, the blistering sun, and the breezing wind are natural elements that wear out a roof at some point. When your roof reaches this point, you have the option to have it replaced, of course. But there is also one more alternative – to have it recoated. 

The question is how often should your roof be recoated. We can say that it should be every 5 years. Having your roof recoated means that your roof will last for more years. Aside from that, if you have your flat roof recoated at least twice in a decade, you will be able to increase the heat reflection properties of the roof. What makes this important is that it will help you keep your roof waterproof. 

How Do You Prepare A Roof To Be Recoated?

There’s more to roof recoating than meets the eye. For one thing, you need to make sure that the roofing material adheres to the roof. For that to happen, you need to make sure that you prepare the roof before the whole process. 

You need to be aware of any incoming rain. Check the clouds. Look at weather forecasts. If there is going to be rain, even if it is just a tiny bit, the best thing to do would be to delay having the roof recoated. To facilitate the drying of the roof, the best conditions would be low humidity and moderate temperature. 

You may want to avoid extreme temperatures. If it is extremely hot or extremely cold, the best course of action would be to delay having your roof recoated. 

You also need to make sure that the roof is free from dirt and other types of debris. Make sure to sweep the roof before having it recoated. It would also be a good course of action to put a bit of primer into the roof. 

You should also check if there are any damages. We recommend that you avoid having your roof recoated if there are damages. You should have it fixed first. Or if not that, you could have it replaced and then you could have your new roof re-coated. 

What Materials Do You Need To Have Your Roof Recoated?

Your options when it comes to materials are either solvent-based or water-based. Urethane is an example of a solvent-based coating. The great thing about this is that it already has an industry-wide reputation for lasting longer. However, solvent-based coatings are also much more expensive. Aside from that, you would really need professional help throughout the application process. DIY roof repairs are not recommended. 

You should use silicone coating if you live in areas with high precipitation. This is because silicone has the ability to resist moisture from rain. The best part is that silicone will start taking effect just a few hours after it has been applied to the roof. 

 

And there is the water-based solvent. These things are a lot cheaper but they also have a pretty high failure rate. Acrylic is one of the most popular water-based solvents. This type of coating comes in the color white. Hence, aside from coating your roof, it can also serve as a heat reflective property. You will probably like Acrylic because it is easy to work with but it can also start to breakdown when there is too much ponding. 

Acrylic will enable you to get your roof coated at a less expensive price but since it is not very good quality, you would have to coat your roof more often. 

Meanwhile, using Silicone will require you to invest quite a hefty sum but the good news is that you’ll only need to have your roof recoated every once in a while. 

What Are The Common Pitfalls Tied To Having Your Roof Recoated?

Even after you have selected the right materials, you could still experience problems right in the middle of the whole thing. Here is an example:

We know that some coatings are created to give the roof a waterproof effect. Even so, this does not mean that it can do the job of covering leaks. Even after you’ve had your roof coated, if there is something wrong with the roof, you could still experience leaks after all the coating. That being said, it is important that you check your roof for leaks before you go about having your roof recoated. 

Other issues can also occur if you have left some moisture under the coating. If this happens, your roof will most likely experience some blistering and delamination. All of this is due to the fact that the insulation will become rigid and wet. The coating won’t be able to seal completely unless you have already applied the primer. 

The solution to this is quite simple. You have to make sure that the roof is absolutely dry before you proceed with getting your roof recoated. 

Get A Professional To Have Your Roof Recoated

As we have already mentioned, Acrylic will enable you to recoat your roof easily and more cheaply but it wouldn’t be the wisest approach. First of all, it will wear off a lot sooner than you could have imagined. With that, you will end up having to spend more due to the frequency of getting your roof recoated. 

The best course of action would be to use Silicone. You will need a higher initial investment but it is the kind of investment that is worth it. You won’t have to worry about getting the roof recoated for about 5 years. 

The catch is that you won’t be able to apply SIlicone on your end. You will need the help of a professional like Renco Roofing to get the work done. But that’s okay. Hiring a professional means that the work gets done right the first time around. Aside from that, you also save yourself the trouble of getting dirty or potentially hurting yourself for doing something you are not experienced in.
