I have owned and operated Mr. Chimney Sweep for 30 years. I am the owner operator of this business. My wife answers the phone, and I have one full time employee, Michael Snider. We are a complete chimney service provider. I have been certified with the CSIA for 30 years, and a member of the National Chimney Sweep for the same period. I am also a member of the Wisconsin Chimney Specialist Guild. Cost depends on the job. We are professional, clean, punctual, and honest.

"The former sweep retired/sold the business. We had him clean our chimney a few years ago and he was ok. This new gentleman is fantastic, very thorough, very professional. His work was much more than we expected. You could tell he really enjoyed and took pride in his work. Excellent work!"

Chimney Sweep questions, answered by experts

It may require stronger cleansers or chemicals, higher-pressure spray, or scrubbing to completely remove algae from a metal roof. Start with a mild cleanser; if that doesn’t work and you're comfortable doing so, use a stronger mix of ⅓ cup of laundry detergent, 1 quart of bleach, and 3 quarts of water to gently scrub the algae with a soft-bristled brush. If algae is present across large portions of your roof, doesn’t come off with gentle scrubbing and cleansers, or is in hard-to-reach areas, this may be a job better left to a pro.

Yes, algae-resistant shingles will prevent algae and moss growth, providing double protection for your roof and roof flashing. The copper-infused granules on algae-resistant shingles release copper ions that inhibit plant growth in general, so moss will have a harder time growing on your roof, too. Keep in mind that copper ions flowing off your roof during rainfall can also inhibit plant growth below, so your gardens and grass may be affected.

Roof cleaning is typically necessary annually, although homes in moist or heavily polluted areas may require more frequent service to prevent buildup.

Even though you don’t look at your roof often, there are some telltale signs that you should have your roof professionally cleaned. It’s best to hire a professional roof cleaner as soon as you notice signs of wear and tear to preserve the essential feature’s longevity. Some indicators to look out for include:

  • Leaf buildup in gutters

  • Dirt and grime buildup

  • Moss or black algae growth

  • Dirt buildup under shingles

  • Shifting roof shingles

  • Plant growth

Yes, you can, but you’ll need to acquire the right pressure washer tips and cleaning solutions for the job. In particular, you’ll need tips that are capable of lowering the pressure from a max of 3,500 PSI to between 150 and 300 PSI. As for the cleaning solution, look for options that are clearly marked for soft washing rather than pressure washing.
