How To Treat Mold on Siding

Here in Connecticut and most of New England, vinyl siding is a popular cladding option for many homeowners. Starting in the 1950s, it became a favorite aluminum replacement due to its low maintenance and high durability. With a wide variety of colors and textures, it continues to be a fantastic option, offering personalized style without having to worry about sanding, painting, or major maintenance. 

While vinyl siding is beneficial in so many ways, one complaint is the potential for mold growth, often on the north side of a home. To be clear, mold can grow anywhere, but the north side is the area that’s most susceptible because it gets the least amount of sun exposure. Constant shade, high vegetation, or anything that stops a house from getting regular sunlight is an invitation for mold to grow in that area, whether it’s clad in vinyl or not.

In addition to lack of sunlight, excess moisture is another mold inhibitor. The cause could be as simple as trapped rainwater that’s unable to drain properly. Another possible issue could be a faulty drain pipe or a gutter that’s dripping on the siding, causing constant dampness. Either way, a moisture problem is something you’ll want to deal with as the water will continue to feed the mold, which will then spread. 

Another reason for mold growth on siding is a build-up of dirt, which is a food source for all different types of fungus. Something as simple as a dryer vent can cause dirt and dander to stick to the siding. Tree sap is also common and can be tough to remove. Homes on high-traffic roads tend to get dirty more easily as well. Any of this debris will quite literally make a meal for spores to feast on. 

So what can you do to keep mold at bay and ensure your vinyl siding looks great for years to come? Assessing your sunlight and moisture exposure is key, but what if you don’t want to cut down a tree or you happen to live in an area where moisture is a problem? A professional will be able to inspect your siding and treat the mold using a cleaner and blocker that removes spores and keeps them from coming back. It’s important to use a specially designed cleaner that is strong enough to tackle mold but not too harsh that it will damage the house. You also want to be careful not to use any bleach-containing materials so as not to harm the vegetation surrounding your home. 

Once your house is cleaned, be sure to maintain your vinyl siding by assessing your home for moisture, treating leaks promptly, and keeping your gutters clear and free of debris. An annual inspection will help to ensure that any problems are dealt with promptly so they don’t get out of control.

Put Roof Cleaning on Your Spring To Do List

A roof covered in black, streaky stains or moss growth could be much more than just cosmetically displeasing. It can also be a sign that your house can’t breathe properly. 

Algae spores get carried by the elements and once they get enough light, heat, and moisture, they begin to grow and spread. Homes that aren’t properly insulated and ventilated are most susceptible to the problem because they hold onto moisture a lot more easily than houses with proper airflow.  Once algae begin to grow on a home, it will spread very fast, resulting in black streaky staining or thick moss. 

If you have one of these problems, the first thing you want to do is find out if your issue is cosmetic or something more serious. Ideally, a homeowner should get a roof inspection at least once a year and late spring is one of the best times to do it. During an inspection, a roofing professional will check the entire surface area for shingle deterioration or damage, and cracking around the flashing. They will also ensure that water is draining properly through the gutters and downspouts. Something as simple as debris build-up can void the roof warranty, so it’s well worth having an expert come and take a look. They will be able to tell you if your stains are something that can be taken care of with simple cleaning or if there is a more significant issue.

If your staining is cosmetic, a roof cleaning takes a few hours depending on the size of the area and one application does the job without the need for pressure washing which can damage the shingles. A roofing expert will use a professional cleaner that adheres to the growth but doesn’t harm the roof or any vegetation below it. Working on a roof is a very dangerous job and I never recommend for a homeowner to do a task like this themselves unless they are very comfortable on a ladder and with heights. No home maintenance task is worth a trip to the emergency room. 

If your roof staining is showing up in the attic, your home is one of many in this area that doesn’t have the right airflow and you may want to discuss insulation and ventilation with a qualified roofing professional. Mold and algae in the attic can easily start to affect the air quality in your home, which is especially worrisome for elderly adults, young children, and anyone with respiratory issues. If you think your home might be affected, don’t put this problem on the back burner. Talk to an expert right away.

Roof Cleaning for a Health Upgrade

If your roof has black, streaky stains or mold and moss growth, a roof cleaning might be just what you need to maintain both the look and the health of your home. 

A stained roof is generally one that has begun to accumulate algae. Spores get carried by the wind and birds and the issue is generally invisible until there is enough moisture, heat, and humidity for them to grow and spread. Homes that aren’t properly insulated and ventilated are also susceptible to the problem because they hold onto moisture a lot more easily than houses with proper airflow.  

If you have staining, the first thing you want to do is find out if your issue is cosmetic or something more serious.

Something as simple as debris build-up can void the warranty of a roof, so it’s well worth having an expert come and take a look.
