Do you have black streaks on your roof? If you do not, consider yourself lucky because most homes in the DC Metro area do. You may be asking why am I seeing more of this on houses today than years ago? These black streaks are actually an airborne algae and they are driven by humidity. So as climate has changed in years we have seen a spike in humidity in our area, causing more black algae streaks. Shingles from 10 years ago and beyond had algae resistance (AR) built in as an option. Yet today all major shingle manufacturers such as Gaf, Owens Corning, Tamko, etc. have built in Algae Resistance ranging from 10-15 year warranties. Unfortunately when the 10-15 years end you may very well see the streaks again due to the nature of airborne. It is cleanable, however the risks of damaging a roof are quite high if caution is not taken, such as never use a pressure washer on your roof to clean it. This is highly dangerous to you and the life of the shingles (not to mention a great way to start a roof leak). This may sound like an obvious thing not to do but then again coffee cups are labeled hot. So you may or may not be surprised by the many people I’ve spoke to that have done this.
So the best bet is to replace your worn roof and cross your fingers in 10 years it doesn’t happen? Because that still sounds like a headache, invest thousands of dollars and 20 years before the roof needs to be replaced it will look awful? Luckily the shingle manufacturers are stepping up to the plate to handle this better. Starting with Atlas Pinnacle Pristine limited lifetime shingles with 3M Scotchguard technology. The first major company to offer a limited lifetime warranty on algae streaks and if it occurs they will replace or clean it. Bottom line, their problem not yours. In the next year other major brands will be offering it too, making unsightly streaks a thing of the past.
