: Roofing & Restoration Services

Water stains on a roof can be unsightly and are frequently indicative of a larger roofing issue. These stains can lower the value of your home and, if left untreated, can damage your roof. If you find yourself in the unfortunate situation of having to deal with water stains on your roof, you must understand what the various colored stains mean and how to properly deal with them. We are one of the top providers of Roofing & Restoration Services in Loveland, Colorado.

Black or Green Stains

Black or green stains on your roof indicate the presence of actual organisms such as algae or moss on your roof. Roof conditions are ideal for the growth of these microorganisms due to the sunlight, heat, and moisture.

White or Yellow Stains

White or yellow stains indicate hard water buildup from an air conditioner or cooler. These stains are frequently found beneath the air conditioning and are highly visible. These stains also indicate a favorable environment for the growth of fungi that can consume an entire roof. Also if you are looking for Insurance Claims Service in Denver, get in touch with our expert team. Keep in mind that even if the roof appears to be in good condition from the outside, there could be serious damage inside that only an experienced roofing specialist can detect.


Regardless of the color of the roof stain, it is critical to act quickly to avoid further roof damage. The first step is to determine the source of the stain so that you can properly address the problem. The stain should then be treated with either vinegar or bleach. Bleach will kill the growing organisms while vinegar will fade the damage.

When in doubt, consult a qualified, reputable roofer. An experienced roofer will usually work faster and more efficiently and will provide you with a solution that will last longer than work done by yourself. Finally, don’t forget about the potentially dangerous trip up the ladder you’ll save yourself.
