When the contractor delivered the sad news that my roof needed replacing, that led to a discussion of material choices. I was surprised to hear that metal roofing was an option. Sure, it was fine for commercial buildings, but a home? My contractor told me that metal is used for homes more than people realize. The panels can be designed to look like just about any type of roofing you can imagine. After looking at some samples and finding out about the long life of metal roofs, I decided to give it a try. Fifteen years later, my roof is still in great shape. If you are facing a roof replacement in the near future, let me tell you more about metal roofing. I'm betting that you'll decide this solution is right for your home.
One of the problems with having a flat roof made with metal is that it can become damaged when rainwater pools for an extended amount of time. This can easily happen if your drains are clogged with debris and the water has nowhere to go. The weight from the pooled water can eventually cause metal roofing material to bend, which will require replacement of a section of the roof. If you have a flat roof, you will need to know how to stop rainwater from pooling, and protect the roofing material by waterproofing it.
Preventing Pooling Water
The disadvantage of having a flat roof is that the slant is very subtle compared to a pitched roof. If gutters are clogged on a pitched roof, the gutters will eventually cause the water to overflow and spill over. The water will collect around your home's foundation, but be off your roof. A flat roof needs drains and downspouts to be in working order because dirt and debris can cause water to easily pool when there is a problem
Since the roof is flat, you may not even notice it is a problem with clogged drains and downspouts unless you go up on the roof and inspect it yourself. It's a good idea to inspect your roof regularly or hire a professional to come to your building to clean the drains for you. Not only does the debris surrounding the drain need to be cleared out, but it is a good idea to have the downspouts snaked to clean out debris that has collected inside.
Waterproofing Metal Roofing
The purpose of waterproofing a metal roof is to provide an additional layer between the metal material and the water. An easy solution is to paint the metal surface because it will provide a sufficient barrier to keep the water away from the metal. The paint will peel or fade over time, which will require repainting.
If you want something more substantial to waterproof your roof, a rubber sealant can be applied to the metal. While it will be more expensive than adding a layer of paint, it will last much longer and require less maintenance.
It's impossible to prevent water from coming in contact with a metal roof, but taking the proper steps will limit the amount of exposure water has to the roofing material. If you need help applying a rubber sealant, a professional roofing company (such as US Roofing) can do the job for you.Share
