How long does it take to clean a roof?

• <div><p>On average, cleaning a roof will take between <b>two to five hours</b>. This timeline depends on the size and slope of your roof and the severity of any stains. <a href="https://www.angi.com/articles/3-roof-cleaning-methods-ugly-stains.htm">Cleaning roof stains</a> can take additional time, especially if there are signs of moss or algae.</p><p>In addition, the age of your roof makes an enormous difference in the time it takes to clean it, as older roofs need more gentle care. If you have significant landscaping in your yard by your house, your professional roof cleaner will need additional time to protect it from cleaning chemicals. </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: What are some signs your roof needs cleaning?

• <div><p>Other than it looking like a dirty car, there are some other signs you need to clean your roof. Moss growth, algae (often black streaks), grime buildup, buildup under shingles, and leaf buildup are all classic signs a cleaning is overdue. If you have neighbors, take a look around. If your roof appears different in any way, that&rsquo;s another sign to call a pro to have it cleaned.</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 do housekeepers not clean?

• <div><p>Most housekeepers won&rsquo;t handle tasks that require specialized equipment or training, like <a href="https://www.angi.com/companylist/carpet-cleaning.htm">carpet shampooing</a>, window washing at high levels, or outdoor cleaning. Housekeepers typically dust, vacuum, mop, wash dishes, clean surfaces, and launder linens. It&rsquo;s best to clarify what services are included before hiring to make sure you&rsquo;re on the same page.</p></div>
