Q: Can I put salt on my roof for ice dams?

• <div><p>It is not advisable to use salt on your roof to prevent or remove ice dams. It&rsquo;s not only mostly ineffective but can also cause serious damage to your roof itself. Salt can rust metal, damage masonry, pit shingles, and cause runoff that&rsquo;s damaging to plants and animals. </p></div>

Q: Should you use a pressure washer on the roof shingles?

• <div><p>If you&rsquo;re asking yourself, <a href="https://www.angi.com/articles/can-roof-cleaning-extend-life-my-shingles.htm">should you pressure wash your roof</a>, the answer almost always is no. The water pressure that the power washing machine generates could damage the shingles by forcing water underneath or causing them to loosen. Soft washing with a pump sprayer is the better and safer option.</p><p> </p></div>

Q: How much does it cost to clean a roof?

• <div><p>The average <a href="https://www.angi.com/articles/what-does-roof-cleaning-cost.htm">cost to clean a roof</a> is around <b>$500</b>, but prices can fall between <b>$150 to $1,000 or more</b>. The size and complexity of your roof are the most significant cost factors, as larger roofs and those with various bump-outs and gables will increase your cost. Your roof material will also make a difference. An asphalt roof will require more labor, as your professional will need to be careful not to damage the shingles. A metal roof can stand up to more intense scrubbing and shouldn&rsquo;t take as long to clean.</p></div>

Q: What does professional roof cleaning typically cost?

• <div><p>The cost depends on roof size, pitch, accessibility, and contamination extent. A steep roof or extensive moss growth may raise the price.</p></div>
