Generally, snow removal from a roof should occur once over six inches of snow accumulates, especially if you notice that ice dams have formed. Without ice dams, you can let the snow accumulation hit 12 inches before removing it. However, the amount of snow that is too much for your roof also depends on the sturdiness of your roof and the compactness of the snow. If your roof needs maintenance or has structural issues, it’s best not to let the snow accumulate too much for fear of collapsing.

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.

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.

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.
