You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

Complete house winterization goes above and beyond the list we created above. In addition to everything listed, full house winterization also includes:

• Performing a home energy audit.

• Preparing your deck and patio for winter.

• Learning how to start a snowblower.

• Replacing smoke detector batteries.

• Installing outlet gaskets.

• Installing storm doors.  

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.

Roof cleaning isn’t a necessity, but it can drastically improve your home’s curb appeal and even prolong the life of your roof, so it’s often a great investment. It’s especially a good idea if shaded parts of your roof experience algae or moss growth, which can damage the shingles and hold water against them, increasing the risk of a roof leak.
