Ideally, you will tackle removing algae from your roof during spring or summer when the weather is drier and warmer. Because algae tends to grow during the colder and wetter months, you want to tackle this project before the temperature drops to hopefully keep it from coming back at all.

The cost of removing snow from a roof averages between $300 and $700. However, this cost can range from $200 to $3,000, depending on the size of your roof, the amount of snow, and roof accessibility. 

Since snowfall can range from light powder to heavy and condensed snow, part of the price of roof snow removal depends on the amount and type of snow. For 12 inches of snow, you can expect to pay between $200 and $2,000 for this job. However, for 24 inches of snow, that price rises to $300 to $3,000.

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.

Inspect for debris, clean drains, and regularly check for punctures or cracks to maintain performance.
