How Do You Clean a Roof

25th April 2023 General

Cleaning a roof is an essential part of maintaining the overall appearance and longevity of your home. Over time, roofs can become dirty due to various factors such as algae, moss, lichens, dirt, and debris build-up. Here are the steps you can follow to clean your roof effectively:

  1. Safety first: Before starting the cleaning process, ensure you take all necessary safety precautions. Wear slip-resistant shoes or boots, use a safety harness, and work with a partner if possible.
  2. Inspect your roof: Take a close look at your roof and identify any areas that need extra attention. Check for any damages or loose tiles that may require repairs before cleaning.
  3. Remove debris: Start by removing any debris from the roof surface using a broom, brush, leaf blower. You may need a low pressure steam cleaner to remove moss and lichens. Be careful not to damage the tiles or other roofing materials.
  4. Apply a softwash cleaning solution: Depending on the type of roofing material, use an appropriate mix. For most roof tiles, use a solution of water and sodium hypochlorite mixed with Green Wash. This method also works on membrane and metal roofs. Apply the solution to the roof surface using a pump up sprayer or a professional grade softwash system.
  5. Let it dwell: Allow the soft wash cleaning solution to sit on the roof surface for about 15-20 minutes. This will give it time to penetrate and sanitise any dirt, algae, or moss.
  6. Rinse: After the solution has sat for a while, use a bulk rinse module or garden hose to rinse off the roof surface. Be sure to rinse thoroughly to remove all traces of cleaning solution. Better still apply Final Wash which will neutralise the sodium hypochlorite.
  7. Inspect and repeat: Inspect the roof after rinsing and look for any missed areas. Repeat the cleaning process as necessary until the entire roof is clean.
  8. Preventive maintenance: To prevent future build-up of dirt, algae, or moss, consider maintaining the roof annually especially if there are nearby over hanging trees.In conclusion, cleaning your roof is a vital part of maintaining the appearance and longevity of your home. By following these steps, you can clean your roof effectively and prevent future build-up of dirt, algae, or moss. However, if you are not comfortable with cleaning your roof or have a large or steep roof, consider hiring a professional roofing contractor to do the job for you.

  • Our listed railway station is built entirely of wood and our Pullman railway carriages  are also built of timber and all these structures require regular and gentle washing, without harmful chemicals, to preserve the paint.  We have used Purple Rhino for over 2 years and their structured approach to this large task ensures our buildings and windows stay in pristine condition.  Their use of specially purified water ensures a streak-free finish every time
