Hazards of mold and algae. Mold? Algae? What’s the difference? Most times, the unsightly stuff on your roof is algae. Algae is pretty much benign. It thrives in humid areas of the country and loves to park itself where there are asphalt roof shingles. Most shingles in the Cedar Park/Leander area are asphalt. Algae will not harm your roof, but does not add natural beauty to your home. Mold is a whole other scenario. Black mold is a big problem here in the Cedar Park/Leander area. It appears on stonework, roofs and inside the home where there is a warm, moist environment. Mold can be a health threat. Allergies, watery eyes, headache, sore throat, sneezing and coughing can all be symptoms of a mold problem. Usually, the roof shows the first signs of mold. This is not a situation calling for a DIY solution. Leave this to the pros who have the expertise, experience, equipment and needed chemicals to do the job with care and as little interruption to the homeowner as possible. Check your roof today for signs of any problems.

However, if your landscape rocks are in need of cleaning, there are ways to remove mold and algae from rocks in a garden. A little dish detergent in a bucket of water, generously applied and then give the rocks a good scrubbing with a stiff brush to remove any surface dirt. You can also use a pressure washer (On lowest setting) and spray rocks with just plain water. If you want to add a cleaner to the water, find one that is biodegradable. However, with a pressure washer, take care not to chip the rocks. Another method is, mix a solution of one part bleach to one part water and put in a spray bottle. Spray the solution on the rocks. If you accidentally overspray onto plants or vegetation, rinse visible foliage and soak the soil with 3” of water to saturate and disperse any bleach in the mix. If needed, scrub again after three or four days to finish up any missed spots and water again.

How to clean mold and algae from vinyl siding. Yes. Vinyl siding can be hit by black mold and algae from rainwater and condensation. A solution of bleach or vinegar will handle the problem. 30% vinegar to 70% water or 20% bleach to 80% water. Then scrub with a soft bristle brush. These same mixes can be used in a pressure washer or the preferred low pressure pump sprayer. A pressure washer might be quicker but if water gets behind the siding it could cause any exposed wood to rot. Take care not to get the liquid under the siding. Cover any nearby plants and shrubs to protect them from any overspray. Also, make sure any outside electrical connections are “Off” and covered.
