If you're into spring cleaning, you might want to add your roof to your list.

First impressions are everything and that's no different for our homes. Having great curb appeal will add value to your home, whether it's on the market or if you plan to stay forever. One major area that everyone sees if your roof.

"Roof cleaning can be a great way to improve the curb appeal of your house. If you see algae or moss streaking on your roof, removing that can make your house look a lot better. But keep in mind, if your roof is old or in need of repair that's the first thing you should be doing before you step to cleaning it," said Angie Hicks of Angie's List.

At face value, roof cleaning can feel like a do-it-yourself project, but it's not. This is a job for a professional.

"When talking to potential companies about cleaning your roof, things you want to be careful of are: anyone that considers pressure washing or abrasive detergents in order to clean the roof, because they could potentially damage your roof or void your warranty," Hicks said.

"We use a solution that we put on the roof, it's called a 'soft wash.' We spray it from the gutter line and we have an air compressor on our truck which run the pumps that we utilize. They are called off low pumps, we are able to shoot 50 feet from the ladder on the roof itself," said Michael Spiczenski, Indiana Roof & Exterior Cleaning.

They're able to get all of that algae and moss growth. Asphalt shingle roofs that are in constant shade tend to attract algae growth, creating black or dark green staining on your roof.

"Most people see that black algae streaking and what that black algae streaking is, actually, the dead cells that are on top of the live cells. It's called geocapsule magnels is the name of the algae that is on there. We totally remove that and kill all of those cells, so they are no longer present. Also, the mold, moss and lichens, we are also able to kill and remove that too," Spiczenski said.

As for cost?

"Roof cleaning is a lot more affordable than what people think. Generally speaking, I'm usually asked 'What is the cost of roof cleaning?' and I tell people it's anywhere between 3-5 percent of overall replacement costs," Spiczenski said.

The pricing is also determined by the amount of infestation, the size and pitch of the roof, and the size of your home.
