Why Would the Best Roofer in Iowa City Clean Their Roof in 2022? — When the siding or exterior of your home gets dirty or grimy, it makes sense to clean it.  The same applies to your roof.  A great way to proactively avoid residential roof repair in Iowa City is to clean your roof regularly. A residential roofing company in Iowa City will all tell you how important it is to clean your roof. Not only can dirt ruin your home’s curb appeal, but it can actually damage your roof, which will then require unwanted residential roof repair in Iowa City. Why does the best roofer in Iowa City clean their roofs?

More Than Just Dirt

Your roof is constantly exposed to weather and elements, every day, all year. Dirt and debris will collect on your roof, which can cause mold and mildew. Don’t let your new roof in Iowa City become an old roof so quickly. Make sure you maintain your roof correctly by cleaning it throughout the year. Natural rainfall is typically enough to wash off the appearance of a lot of dirt, but dark stains and green areas will need more elbow grease. Remember to look out for:

  • Algae
  • Fungus
  • Moss

Your roofing company in Iowa City has likely come up against algae more than once and will be able to help guide you through the process of resolving the issue. Black stains called by algae are called Gloeocapsa Magma (GM). GM algae is a bacterium that feeds off of both asphalt and limestone, making your roof a cozy place for it to live. The best roofer in Iowa City will explain that moist, cool, or shaded areas of your roof are great places for GM to hide. GM can quickly spread from rooftop to rooftop through the means of wind or animals, so be on the lookout for this dangerous type of roof algae.


Lichens are best described as a combination of algae and fungus. These plant-like organisms form a branching growth or roof-like tentacles that penetrate deep into your shingle. They are looking for oil for nourishment. They can be tough to remove from a roof and can likely appear amongst rain and humidity.

The best roofer in Iowa City wants to remind you that unlike the algae and lichens, moss is an actual plant. Moss has a shallow root system and requires a lot of moisture to survive. Areas on your roof with less sunlight will dry slower and remain damp for longer. These areas are one of the moss’s favorite places to hide. Overhanging tree branches not only provide more shade for moss to grow but also drop debris onto your roof which is a great food source for moss.

Finding and removing moss is an essential part of maintaining the health and wellness of your roof. Call Robison, a premier roofing company in Iowa City, to help clean and maintain your roof.
