How to Remove Moss from Your Roof?

roof cleaning

Moss grows in damp and shady environments. It not only looks unclean but also gives your home a ghostly look. If it grows on roofs, it can severely damage the surface and structural integrity of your roof and home. So, removing it is a must-do. We’ve put together a roof cleaning guide for you to get rid of any moss on your roof and to keep it from coming back.

Why does moss grow on roof?

Moss is a soft green plant that can quickly grow in humid areas with a pH range of 5.0 to 5.5. Its development depends upon the type of surfaces like wood, clay, asphalt or metal.

How to remove moss from your roof?

  1. Gather equipment

To remove the moss, first you need to gather the following equipment:

  • Safety glasses or goggles
  • Rubber gloves
  • Safety rope
  • Work clothes, including a cap to protect your hair, and slip-resistant footwear
  • Ladder
  • Garden hose equipped with a spray nozzle
  • Moss-remover of choice
  • Backpack-style garden pump sprayer or a large spray bottle
  • Scrub brush
  • Long-handled soft-bristle brush
  1. Pick a cloudy day

Choose a cloudy day to do this job. Cloud cover gives the chemicals and roof cleaning products time to be absorbed into the roof. The longer the chemicals can sit, the better they will be absorbed. However, don’t leave them too long. About 20 minutes is enough.

  1. Dress for the job

Cleaning moss off a roof is a messy job and can be somewhat dangerous. Wear old clothes that fit well, so they do not snag or restrict your movement. Put on safety glasses, rubber gloves, a cap and slip-resistant shoes too.

  1. Protect nearby plants

Before getting on the roof, you’ll need to protect any nearby plants and trees. This is because some moss removers can kill other plants. As you clean the roof, some chemical run off may land on nearby plants.

If possible, choose an environmentally friendly product. Otherwise, use plastic sheets to cover nearby plants and wash plants off after you’ve finished cleaning the roof.

  1. Hose moss off

Use a hose to spray water over your roof. This should remove any loose moss. Remember to work down from the top of the roof so that the moss washes off the roof.

  1. Scrub the moss

Using the two brushes, work from the top down to scrub any remaining moss from the roof. Rub it gently and do not scrape or scour the roof. It is best to work in small sections to avoid any breaking or cracking roof shingles or tiles.

  1. Apply chemicals

To prevent moss from growing back, use your moss killer. Use a spray bottle or backpack-sprayer and only use what you need.

You can also install strips of zinc or copper-coated sheets below the ridge to change the pH balance on your roof. These metals are toxic to moss and algae, and you can purchase them in rolls. Attach these sheets using screws and roofing nails.

When it rains, the metal elements are washed off the sheets and onto the roof, making it unpleasant for moss to grow on the roof.

Don’t forget to trim back any overhanging trees and branches so that your roof gets as much sun as possible, so the damp conditions that moss likes are less likely.

  1. Rinse the roof thoroughly

Once the chemicals have had time to sit, use a hose to rinse them off the roof. Don’t use a power washer as it can break or chip tiles or shingles.

Even if you do not use any chemicals, rinse your roof thoroughly to clear away any remaining moss.

Don’t forget gutter cleaning either. Make sure your gutters aren’t clogged with moss debris.

  1. Scrub again if needed

After rinsing, if there is any moss remaining, scrub it off and then rinse again to clean the roof. Any remaining moss can quickly grow back and take over the roof once more.

Why is moss prevention needed?

If moss grows on your roof, it can damage your roof and home’s structural integrity. It can cause holes and leaks in your roof, damaging the ceilings, walls and furniture. So, it is better to handle moss before it gets worse. Clean your roof thoroughly, using chemicals if you need to and then make sure to install metal strips and make your roof as unpleasant as possible for moss.

Why is safety necessary while removing the moss?

It’s important to take safety precautions when removing moss from your roof. Working on a roof is dangerous anyway, you can easily lose your balance and fall or misjudge where the edge is.

Dress appropriately, including goggles, gloves and slip-proof footwear. Take your own safety seriously. Every roof can develop moss but by following the above cleaning steps, you can get rid of it and prevent it from coming back.

How to Clean a Tile Roof?

Tiles are the perfect choice when you want to have a roof that is both durable and aesthetically pleasing. The reason why tiled roofs are popular among many Melbourne residents is that they can withstand harsh weather conditions better than other roofing materials. Whether it’s a the baking summer sun, a storm or heavy rains, tile roofs offer guaranteed protection to your home, all seasons in all weather. They also provide excellent insulation, keeping your home warmer in winter and cooler in summer.

However, like all roof materials, tiles also need proper care and maintenance to give you long-lasting protection. Whether you want to prevent leaks or to keep your roof looking brand new, you must include tile roof cleaning as part of your regular home maintenance. When you ignore this regular cleaning, you will notice a build-up of organic matter on the tiles that changes the roof’s appearance and thus affects the overall look of your home.Moss, dirt and debris can affect the quality of your roof, leading to leaks and other roof damage.To prevent this, you should have a regular roof maintenance schedule that includes cleaning your roof.

But how do you clean a tile roof and what equipment do you need? Thankfully, we’ve put together this guide just for you.

Tools and Materials Required:

  • Extension cord
  • Rubber gloves
  • Safety equipment (like safety glasses, non-slip shoes)
  • Garden hose and garden spray nozzle
  • Non-corrosive mild cleaner
  • Supplemental water pump
  • High-pressure cleaner
  • Outdoor cleaner with a power sprayer
  • Roof guard rails

Procedure for Roof Cleaning

  • Safety first

Before you get on the roof, make sure you are wearing non-slip shoes as well as safety glasses to protect your eyes from harmful chemicals and splashing water. Once on the roof, install a strong and sturdy roof guard rail so you have something to hold on to and prevent you from falling. It’s also recommended that you have someone else with you at all times. While you clean, they can help by passing tools and ensure that you do not fall or have an accident.

  • Disconnect any water tanks

If you have any water tanks that are connected to your guttering, for instance, rain water tanks, disconnect them so that any run-off from your cleaning does not go into the tanks. As you will be using chemicals to clean, this keeps your tank free from harmful chemicals.

  • Prepare the tiles

The first cleaning step is to remove the visible dirt and debris that’s accumulated on the roof tiles. For this, you can use a high-pressure water pump to wash off any dirt and loose leaves. When you are doing this, remember to walk only on the overlapped portion of the tile roof as it’s the strongest part.

  • Apply anti-moss spray

The next step is applying the anti-moss spray. Start by spraying the cleaning solution on the lower part of the roof. This is because you will need to walk backwards to spray and not step on the tiles that have been sprayed, so by working from the base of the roof to the peak, you are less likely to fall off the roof.

  • Let the spray sit for a few minutes

For effective cleaning, leave the spray on the roof for a few minutes. This ensures that the cleaning solution seeps into the tile’s pores completely. When this happens, the chemicals have a chance to dissolve the spores and thus remove dirt.

  • High-pressure water spray

The last step is to wash away the chemicals by using a high-pressure washer. This step is crucial to get your roof looking brand new. Increase the pressure where there are stubborn stains and make sure to keep spraying until the dirt is completely gone. Also, it’s best practice to start from the peak of the roof and work your way down to the lower tiles so that you are gradually pushing all the dirt off the roof.

Don’t forget about gutter cleaning!

Gutter and roof cleaning go hand in hand as anything that washes off your roof goes into the gutters. Gutters are often filled with debris, moss and algae and regular gutter cleaning is need to prevent these build-ups and keeping your gutters working as intended. Therefore, once you have washed your roof, remove any dirt and debris that has fallen into your gutters.
