Chemical herbicides will kill moss permanently. The same goes with bleach water. However, moss can start growing again once a new layer of dirt and debris is caught in your sand in paver joints. Therefore, the problem is not about killing moss permanently, but ensuring effective prevention of moss regrowth.

While removing every snowflake from your roof is unnecessary, you should remove a significant buildup of snow. Since snow is wet and heavy, it can easily cause damage to your roof, which can lead to needing costly repairs. 

Additionally, when the snow melts but has nowhere to go and refreezes, it can create an ice dam, causing mold concerns due to water leaking into your attic and ceiling. For these reasons, it’s best to hire a snow removal professional to clear heavy snowfall from your roof as soon as possible.

While it’s not completely necessary for them to operate properly, as the occasional rainfall can rinse away dirt and debris, manually cleaning solar panels from time to time can keep them operating more efficiently.

Dirt, debris, pollen, and bird droppings can collect on the surface of the panels. Depending on the amount of solar panels you have, this can add up over time, so set a regular maintenance schedule. Moreover, if you live in a climate with little to no rainfall, more debris can accumulate, causing inefficiencies that would be clear in your electricity bill. 

There are several telltale signs that your roof needs to be professionally cleaned. It's best to hire a professional as soon as you notice any indicators of wear to preserve your roof's longevity. Key signs to look for include:

• Moss, Algae, or Plant Growth: Look for moss growth, black streaks (which are often a type of black algae), or any other plant life on your roof's surface.

• Dirt and Grime Buildup: A general layer of dirt and grime can accumulate over time.

• Leaf Buildup: An accumulation of leaves, especially in the gutters, is a clear sign.

• Buildup Under Shingles: Dirt and debris can get trapped under the edges of your shingles.

• Shifting Roof Shingles: While this can indicate other problems, it can also be a sign that cleaning and maintenance are overdue.

• Comparison to Neighbors: If your roof appears significantly dirtier or different from your neighbors' roofs, that’s another sign it may be time for a cleaning.
