Frequently Asked Questions
Choosing a roof cleaning provider is an important decision, and we want you to feel confident every step of the way. Below are some of the most common questions we get from homeowners just like you—covering everything from safety to service details. Don’t see your question here? Just reach out—we’re happy to help!
What can I expect on the day of service?
We’ll call or text when we're on the way to your home on your day of service. You don’t need to be home for outside work, but we’ll knock on the door to greet you either way. We’ll let you know if we have questions for you or if your home could benefit from any additional services. When finished, we will come to the door to chat before we leave. We can answer any other questions you may have, let you know if we encountered anything unusual during our work, and offer recommendations for a service schedule going forward.
How do you keep from falling off the roof?
We start out by hiring people with a natural talent toward working on uneven surfaces. We hired GRAVITEC to supply and train our technicians in the use of fall protection equipment (ropes and harnesses). In addition, we use high-quality ladders with leg levelers and stabilizer bars and Korkers® brand safety sandals for traction on slippery roofs.
Will it harm my roof if someone walks on it?
Some roofing materials are more fragile than others, and we are very familiar with the different types of material and proper methods for walking on them. The real answer to this is that allowing debris and moss to accumulate on your roof does much more damage than carefully walking on the roof to maintain it. We will certainly assess your roof and determine our ability to work safely, and your roof's ability to sustain our walking on it.
What should I do to prepare for the roof cleaning service?
We will likely need access to your yard waste bin to dispose of the debris from your roof. If you won’t be home, please unlock your gates so we can get all around your home. If you have any pets, it’s best to keep them inside while we work. We may need access to water from your outdoor faucets in order to clean up afterwards, so please make sure the water is turned on. You may want to move your car away from the home, and it’s best to cover your outdoor furniture, particularly if you have fabric cushions.
Should I pressure wash my roof?
No, we advise our clients against pressure washing roofs. Pressure washing often damages composite roofs and reduces the life of the roof because it washes off a layer of the roof.
How do I remove roof moss in an environmentally friendly way?
Choosing the right moss treatment for your specific situation and knowing how to apply the right amount in the right way is the key to environmentally responsible moss removal. Our technicians are trained and licensed to apply moss treatments and will use their expertise to take care of your home and its surroundings while safely and effectively killing the moss on your roof.
How do I remove moss on my roof safely?
By choosing AA Window, Roof & Gutter Cleaning for roof cleaning, you ensure that your roof will be cleaned safely by trained technicians. First, we blow the loose debris from the roof with commercial grade backpack blowers. Next, we use a stiff brush to gently agitate the larger clumps of moss, and then use the blower again. Finally, we clear all the debris from the gutters and downspouts, treat the roof, and do a thorough clean-up.
