It is possible to wash your own roof, but we don’t recommend it. First, getting up on any roof is dangerous without proper safety equipment, especially if wetting a metal roof and making the surface slick. Additionally, it’s easy to damage your roof or force water between roof seams if you use a power washer, which can lead to property damage. Hiring a professional roof cleaner will save you time, keep you safe, and ensure that your roof looks new again without damaging it in the process. Plus, roof cleaning is a relatively affordable home improvement project.

There are several ways to remove snow from your roof: using a snow rake, salting the roof with calcium chloride, using a rope (cautiously), and using heating cables. It’s important to mention that pretty, fluffy, sparkling snow weighs a great deal, and when physically removing snow from a roof, you should be aware of large snow slabs breaking off. These can weigh hundreds of pounds and are a real danger, so be extremely careful anytime you’re doing this type of work.

Roof cleaning can damage shingles if it’s done incorrectly—like with a high-power power washer—but it likely won’t damage your roof if you pay to have an expert do the work. A professional roof cleaner will use a gentle cleaning solution and a cleaning method that matches your roof material to ensure the process doesn’t damage the roof. Some homeowners worry that roof cleaning will shorten the life of their roof by removing shingle particles or protective coatings, but it often extends roof life by removing plants that cause damage and improves your home’s curb appeal simultaneously.

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.
