How to Clean Your Roof

How to Clean Your Roof

Did you know that the average American spends nearly 6 hours each week cleaning their home?

While you may spend hours a week cleaning the inside of your home without even thinking, how much time do you spend cleaning the outside of your home? Specifically, how much time do you spend cleaning your roof?

Your roof, just like other parts of your home, needs a good clean once in a while to stay in top condition. But, how do you clean it?

Check out this guide to discover how to clean your roof.

Roof Cleaning Basics

Cleaning your roof is a pretty straightforward process. Here are the steps you need to follow to clean your roof:

  1. Use rubber gloves to scoop up any dirt and debris that may have accumulated in the crevices and roof shingles
  2. For areas you can’t reach, use a vinyl rake to remove dirt and debris
  3. Trim any overhanging tree branches away from the roof
  4. Use a safe, gentle cleaning product to remove any moss, mildew, or algae from the roof
  5. You can also use a specially-formulated spray cleaner on your roof once per year

Know What Type of Roof You’re Working With

Just as you’d clean carpeted floors differently from wood floors, so too do you need to clean your roof differently depending on the type of material it’s made from. Here are some things to keep in mind when cleaning different types of roofs:

Asphalt Shingles

You should avoid pressure washing asphalt shingles. You should also avoid using harsh products like bleach on shingles, as these can discolor them or prematurely degrade them.

Also, keep your eye out for granules when cleaning your asphalt roof, as this is a sign your roof is nearing the end of its lifespan.

Concrete and Clay Tile

Avoid harsh chemicals and pressure washing, as this can erode the paint and tile coatings. Also, avoid walking on your tile roof as much as possible.

Tiles tend to collect efflorescence, which is a whitish, chalk-like covering. To remove this, dry buff your roof with a clean cloth.

Wood Shakes and Shingles

Wood shakes and shingles should also be kept away from pressure washing and harsh chemicals. If you find moss on your wood roof, remove it swiftly, as this can quickly lead to damage.


Slate is water absorbent and cleaves easily, so cleaning it on a regular basis is very important.


While metal roofing is very durable, it’s also susceptible to rust and corrosion. To prevent rust and corrosion, make sure you clean it on a regular basis.
