Looking for new roof installation or help getting a roof repair done? You’ve come to the right roofing company for help! Here at Destin Roofing, we get questions all the time about having a roof that is able to collect rainwater. Here are a few of the best types to make that happen.
Installing a metal roof that is galvanized is a great investment. Depending on what kind of metal roofing you get affects the price, but they are all great for collecting rainwater. They are covered with a zinc layer that seals the metal and iron from getting into your water. There is a chance your metal roof will collect soil-related bacteria, but no worries. All you have to do is filter the water out – especially if you’re using it for drinking water.
A great alternative, if you’re afraid to get traces of metal in your water, is a clay tile roof. However, this type of roofing requires a lot more maintenance. Clay roofing absorbs water, so it is subject to moss and algae growth. This can be prevented by painting the roof with lead-free paint. Pressure washing it annually can also help prevent the growth.
Not all shingles are great for rainwater collection, but there are some. Asphalt shingles are one of the most common materials used for roofing. The uneven surface makes it harder for dirt and pollutants to collect on top of it. During the first year of it being installed, it is suggested to not use the water collected. Higher amounts of dissolved organic carbons are found in the water in that time. This material isn’t toxic until it is combined with chlorine. Asphalt roofs before 1980 should be replaced, or the water collected shouldn’t be used. Shingles this old can contain asbestos, which is toxic. Otherwise, asphalt shingle roofing is very good for rainwater harvesting.
Clear any branches that are above your house to further prevent the number of contaminants that fall. All roofs collect some sort of moss, dirt or bacteria, so regular cleaning and maintenance is important. It is smart and safe to disinfect and test your water annually – no matter which kind of roofing you get.
