How can I clean the outside of my house without a pressure washer?

• <div><p>Long-handled telescopic brushes are the best way to clean the outside of a house without a pressure washer. There are even special attachments for <a href="https://www.angi.com/articles/clean-outside-windows.htm">cleaning the outside of windows</a>. Use a gentle cleaning solution for both the roof and siding to avoid harming the finishes. Be sure to rinse the area thoroughly with a garden hose after scrubbing.</p></div>

Do you need to clear snow from the roof?

• <div><p>While removing every snowflake from your roof is unnecessary, you should remove a significant buildup of snow. Since snow is wet and heavy, it can easily cause <a href="https://www.angi.com/articles/did-storm-damage-your-roof.htm">damage to your roof</a>, which can lead to needing costly repairs. </p><p>Additionally, when the snow melts but has nowhere to go and refreezes, it can create an ice dam, causing mold concerns due to water leaking into your attic and ceiling. For these reasons, it’s best to hire a snow removal professional to clear heavy snowfall from your roof as soon as possible. </p></div>

Q: Should I remove icicles from my roof?

• <div><p>In most cases, it&rsquo;s a good idea to leave the icicles on your roof and wait for the warmer weather to melt them away naturally. You should only remove icicles if you believe they&rsquo;re heavy enough to cause damage to your home or anyone who enters it.</p></div>

Q: Should you use a pressure washer to remove moss growing on a roof?

• <div><p>You could <a href="https://www.angi.com/articles/6-ways-void-your-roof-warranty.htm">void your roof warranty</a> using a power washer if you have a newer roof. With an older roof, you could knock loose older shingles. On the other hand, some people safely use a pressure washer to remove moss from a metal roof. Although you may want to use a pressure washer, the truth is that you probably don&rsquo;t need it to knock moss loose. A garden hose and brush will do the job just fine and in a safer manner than a pressure washer.</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>
