One of the little-known benefits to metal roofs is that you can paint them. When you paint traditional roof shingles a lot can go wrong. If you choose the wrong kind of paint and do not apply it appropriately, you can compromise your roof and open yourself up to moisture problems. When you are painting a metal roof, while there are some things to consider to get the best possible results, there are not the same fears associated with ruining your roof. Here are some common mistakes to avoid when painting your metal roof.
Using Old Paint
If you have previously painted your shutters and door to match and would like to paint your roof in the same colour, it is best to get the right paint and do your best to match it or have it custom mixed, then to just use leftover paint. For one, you will not have enough leftover to paint your whole roof. Two, the paint is probably not the right kind. There are benefits to going the extra mile and purchasing metal roofing paint. Metal roofing paint is often heat and fire-resistant and can also repel pests to keep them out of your attic.
Going without an Energy-Efficient Paint
Metal roofs can have a tendency to heat up, which is why going with a paint that has an Elastomeric coating can save the day. This coating helps to reflect the sun and will keep your house cooler, which means you will not have to turn the AC up during the summer. Elastomeric coatings must be applied thicker, as well, and as a result, tend to keep leaks at bay.
A sealant is not just an additional layer of protection; it chemically bonds the paint to the metal so that it does not peel off. Sealant is incredibly important in making sure that your paint job stays in place and that you will have a beautiful roof for years to come.
A common mistake when painting your metal roof is to use too much or too little paint or to put it on in a method that will lead to peeling and problems down the line. An airless sprayer is the best way to paint a metal roof, but you can use rollers and brushes that are designed for use on metal.
Not Preparing Your Roof
If your roof is new, you must wait six months before painting so it can weather. Before you paint, you also need to pressure wash at a pressure of 2,500 lbs per square inch. By power washing, you remove oil, mildew, mould and anything else that will get in the way of the paint adhering. It also will remove old paint and give you a great substrate to paint onto. Do not skip this step!
