It can be dangerous to remove icicles from your roof, so the best option is to treat the underlying issue instead, usually by ensuring proper insulation in your home. If you’re concerned about immediate damage, you can hire a professional to remove the icicles and the snow accumulation on your home to prevent the issue from recurring. Just make sure you use a long-term solution, too, like addressing insulation problems or installing roof heating coils on your roof.

The best time of year for roof cleaning depends on the climate in your area, but in most cases late spring or early summer are the best times. You should plan to clean your roof when it’s dry and not too hot or cold. It’s also a good idea to clean your roof in the late autumn to remove any built-up debris like leaves or branches. On the other hand, you shouldn’t clean your roof when it’s too cold, because you can cause ice buildup.

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.

Vinegar will not damage your roof shingles. Using vinegar to wash your roof is an effective and popular cleaning method for asphalt shingles. You can buy white vinegar with varying concentrations of acetic acid. Typically, 5% is all you need for a good roof cleaning, but if you’ve got stubborn stains or moss you can go as high as 25%.
