One question we at Miami Roof-Tech often get asked is “Should I clean my roof?” The definitive answer to that is… yes! Not only will improve the overall aesthetic appearance, it will also increase the longevity exponentially of your Miami Roofing system. The other question is then… how often? Here are a few tips to help with both of these:
You may notice dark streaks or splotches that pop up in various areas on the shingles and tiles of your roof. This is actually due to algae and lichen growth, which is common, especially in humid environments like South Florida. If routine care and maintenance are not performed, these organisms can do long-term damage, eventually eating through shingles and into the roof decking, causing wood rot.
There are various methods for cleaning a roof. One option is to use chlorine or phosphates to remove the stain causing organisms. This method involves applying several coats of the chosen chemical to the roof. Stains don’t always come off on the day of treatment so the results may not be instant, but will eventually fade as rain and the elements take effect. This method will also require that the surrounding landscaping be protected during application, since run-off from these chemicals can wreak havoc on plants and vegetation.
Another option is an eco-friendly method that avoids the use of harsh chemicals. This method uses eco-friendly stain removing products and a low-pressure rinsing spray to remove all surrounding algae, lichens, and stains from the shingles. You will notice a difference in the look of the roof immediately.
Avoid using a high-powered pressure spray on your roof as this can actually cause damage to the shingles or tiles. A good rule of thumb is to make sure you can hold your hand under the spray from the pressure sprayer. If you can’t do that, then the pressure is too high.
You should hire a Miami Roofing contractor who is knowledgeable with the type of roof on your home as well as the appropriate methods needed to clean it. A reputable company will usually provide you with a guarantee or warranty on their work. A shingle roof will typically require a cleaning every 2-3 years years. Tile roofs should be cleaned more often, usually annually as they are more prone to algae. Roof cleaning is an important part of your home maintenance. It will help prolong the life of your roof and keep your home looking great for years to come.
