2 Things That Are Making Your Shingle Roof Dirty

Even the best roofing systems and materials are bound to get dirty at some point. It’s only a matter of time before the dirt becomes really noticeable. When it becomes difficult to ignore the stain or unsightly marks on your roof, it might be time to clean your roof. But first, you might be wondering, “What exactly is making my shingle roof dirty?” Here are some answers.


If you’ve had your roof for quite a while, chances are you’ve noticed black stains marring the roof surface. These stains are often referred to as roof mold, which are actually just algae that thrives on damp portions of the roof.

While roof mold is mostly harmless, it is a serious cosmetic problem that needs to be dealt with immediately. There are algae-resistant shingles on the market, but you can purchase specially formulated cleaners if your roof already has algae growing on it. Just refrain from using a pressure washer to remove the stains.


Organic debris like leaves, twigs, pine needles, pine cones and even acorns that fall on your roof can make your roof look dirty, even if the shingles underneath the pile of debris are in pristine condition. The buildup of leaves and sticks can make it difficult for rain water to slide off the roof, causing water pooling and roof damage like leaks and deterioration.

Some damage is even so serious that it prompts a gutter replacement as well. You can prevent these issues by cleaning your roof by hand or by using a leaf blower with an extension wand.
