4 Types of Fungi that Can Grow on Your Roof

While you may believe that you are the only one living in your house, there may be some microscopic creatures making a home above your head. Roofs are the perfect place for fungi to live due to the damp and humid conditions, and leaving these organisms on your roof can have disastrous consequences. The best thing you can do is keep an eye out, and as soon as you spot it, you can get it removed to save your roof from further damage. But how do you know what to watch out for? This blog post will go over the 4 types of fungi that you might see growing on your roof.


Algae is a living organism that feeds off the limestone filler in shingles. Once the spores land on a moist area, they quickly spread and devour the roof. Algae is black-green in color and it loves to grow on damp, humid areas like roofs and gutters.

Algae eats away at shingles, taking years off the life of your roofing; you’ll have to get it replaced sooner rather than later, which can cost $10,000 or more. Not only that, but algae can also increase your electricity bills. Since the growth of algae covers the roof, the shingles aren’t able to effectively block UV rays, thus heating up the interior and forcing your A/C unit to work overtime. As soon as you notice algae on your roof, you have to act, as it can cost you thousands of dollars if you don’t get rid of it immediately.


Moss is distinguished by its fuzzy texture and vibrant green color. Some homeowners like the appearance of moss on their roof and keep it there for aesthetic reasons; however, the quaint forest cottage look comes at a risk – as moss can be detrimental to your roof.

Moss is attracted to damp, low-sunlit areas and contains moisture that can seep into shingles, causing roof rot. A rotting roof has poor structural integrity, leading to a flood of other issues. If you like the look of moss and know how to properly maintain it, moss can be a great addition to the roof of your home. But, if you dislike the look, getting it removed is the best option.


Mold is the most problematic fungi on this list. Not only is it ugly, but it can actually cause severe health problems, such as allergies, asthma, and other respiration issues. This organism is characterized by a slimy appearance and rancid smell. It can be brown or dark green in color, but black mold is the most hazardous.

Mold grows on moist wood and drywall, so roofing is the perfect place for it to grow. Once mold finds a home on your roof, it spreads fast. A roof leak can cause it to get inside of your home, and then circulate through the HVAC system. It also eats away at the structural integrity of your house, and simply the presence of mold decreases the value of your property. If you notice mold growing anywhere in your home, make sure you contact licensed professionals right away to remove it.


Mildew has a powdery texture and can be light gray, black, or even pink. It loves warm, wet areas and especially grows on roofs with poor drainage. Mildew is known for spreading extremely fast, and it can be incredibly unsafe if you let it grow and fester.

Just like mold, mildew is a serious health hazard. Breathing it in for prolonged periods of time is dangerous, especially to those with asthma or other respiratory problems. Not cleaning your roof puts your family’s health at risk; make sure that you call the professionals right away as soon as you notice mildew growing on your home.


Algae, moss, mold, and mildew thrive in moist, humid areas. While there are ways to prevent them from growing, the absolute best way to stop them from spreading is by getting your roof cleaned regularly.

3 Ways Pressure Washing Can Increase Your Home’s Value

For home owners, the most common problem is the upkeep of gutters, roofs, and other parts of the home that are hard to clean. Luckily for you, the hardships of clearing away debris and dirt can be taken care of by scheduling a pressure washing service. With professional pressure washing equipment, the high-pressured water (with a combination of other chemicals), can prevent build-up of mold and other harmful particles that may be affecting the exterior of your home. Keep reading to find out how pressure washing can increase your home’s value and save you tons of money in the future!

Prevent Mold and Build-Up

One of the key benefits of pressure washing is removing harmful material from the exterior of your home. Over time, siding and shingles can become host to a variety of harmful growths such as algae, mold, and mildew. In all exterior surfaces, but especially materials such as limestone shingles, the buildup can cause damage when left untreated.
(Did you know: mold is the leading cause of roof decay!)
Regular washing can extend the life of your siding and roofing, saving you costly repairs and replacements down the line. The National Association of Realtors claims that a pressure wash can add $10,000-$15,000 value to your home, should you decide to sell. This simple routine maintenance can net you significant gains on the housing market.

Keep Gutters Functional

When your gutters become clogged with dirt and debris, water cannot flow away from your home; this may cause problems with the exterior of your walls, as the water saturates the outside over time. If water is affecting your walls, the overall integrity of your home could possibly be in danger, but don’t fret!

With a little preventative treatment, you can potentially save yourself from numerous problems- such as damaged door trimmings and leaky basements. Better to save yourself the headache and potentially thousands of dollars with a pressure washing cleaning!

Identify Maintenance Needs

When your home is treated with pressure washing, it may help you identify and get ahead of maintenance issues before they become big problems. Cleaning away dirt and debris from your home may expose a number of unknown areas for improvement.

By power washing the house, you can take note of any loose, cracked, or missing siding as well. Fixing issues that may be uncovered during a pressure wash can help maintain the exterior integrity of your home and prevent further structural damage. Ensure your home is free of rot, decay, and premature aging by treating it to a routine clean!


All in all, pressure washing can be a preventative measure to keep your home exterior clean and maintain your home’s value for years to come. With a simple maintenance cleaning, your roof, shingles, gutters, and more can be free from debris and other particles which build up over time. In addition, it can increase the value of any home, especially if you ever decide to sell.
