Q: Will vinegar hurt roof shingles?

• <div><p>Vinegar will not damage your roof shingles. Using vinegar to wash your roof is an effective and popular cleaning method for asphalt shingles. You can buy white vinegar with varying concentrations of acetic acid. Typically, 5% is all you need for a good roof cleaning, but if you&rsquo;ve got stubborn stains or moss you can go as high as 25%.</p></div>

Q: Should asphalt shingles be power washed?

• <div><p>No, asphalt shingles should not be power washed. A power washer or pressure washer is too strong to use on asphalt shingles and will loosen the adhesive holding them to your roof, causing them to fall off.

Q: Can roof cleaning cause leaks?

• <div><p>An improper DIY roof cleaning could cause leaks by damaging the roofing material.

All Mountain States Pest Control did a great job. They returned phone calls, showed up on time, and took care of the problem. They had to special order the right size of chimney guard, but kept me informed of timing and returned to finish the job when the chimney guard arrived.
