Q: What kills green algae?

• <div><p>Vinegar, bleach, chlorine, barley straw, and a bevy of dedicated algaecides can kill algae, which is the easy part. Preventing algae from returning can be a struggle for some homeowners, but keeping the patio well-maintained and clean is a good first step. </p></div>

Q: Can moss damage my roof?

• <div><p>Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof&rsquo;s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the <a href="https://www.angi.com/articles/how-much-does-roof-replacement-cost.htm">cost of roof replacement</a>.</p></div>

Q: What happens if you don't shovel your roof?

• <div><p>Clearing snow from your roof can be a tedious and time-consuming job. Even so, it is extremely important to maintain your roof during the winter months. You can help prevent ice dams and avoid roof collapse.</p><p>As a side note, rather than shoveling your roof, you should always use a roof rake to modify the job. Otherwise, call in a professional.</p></div>

Q: Is bleach or vinegar better to kill moss?

• <div><p>Bleach and vinegar can both kill moss effectively. However, if you&rsquo;d rather use a non-chemical option that&rsquo;s better for the environment, vinegar is the choice. Depending on the paver material you use, vinegar and bleach can also stain or discolor the surface. When unsure, test and use the option that doesn&rsquo;t react with your paver material. </p></div>

Q: Can roof cleaning cause leaks?

• <div><p>An improper DIY roof cleaning could cause leaks by damaging the roofing material. Things like using too much water pressure on the shingles or applying a harsh cleaning solution could cause damage. If you do enough damage, you could harm the ability of the shingles or other roof materials to keep water out of your home.</p></div>
