Roof Cleaning questions, answered by experts

The best time of year for roof cleaning depends on the climate in your area, but in most cases late spring or early summer are the best times. You should plan to clean your roof when it’s dry and not too hot or cold. It’s also a good idea to clean your roof in the late autumn to remove any built-up debris like leaves or branches. On the other hand, you shouldn’t clean your roof when it’s too cold, because you can cause ice buildup.

Iron, or ferrous sulfate, is one of the fastest methods for killing moss. As such, you’ll find this ingredient in many lawn fertilizers and lawn killers. Vinegar is another solution for quickly killing moss. It takes just 15 to 20 minutes for vinegar to take effect. A harsher method is bleach, which also has a similar time frame for taking effect.

On average, cleaning a roof will take between two to five hours. This timeline depends on the size and slope of your roof and the severity of any stains. Cleaning roof stains can take additional time, especially if there are signs of moss or algae.

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.

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.
