Pressure cleaning roof tiles

Pressure cleaning roof tiles
Pressure cleaning is an effective method for removing moss and black algae from roof tiles. Here's a step-by-step guide on how to pressure clean your roof tiles to eliminate these issues:
Safety precautions: Before starting, ensure you have the necessary safety gear, such as goggles, gloves, and non-slip footwear. Also, cover any nearby plants or delicate areas with plastic sheets or tarps to protect them from potential damage.
Equipment setup: Set up a pressure washer with an appropriate nozzle for the job. A medium- to high-pressure nozzle is usually suitable for cleaning roof tiles. Follow the manufacturer's instructions for connecting the hose, adjusting pressure settings, and filling the detergent reservoir if applicable.
Pre-treatment: Before applying the pressure washer, it's recommended to pre-treat the moss and black algae with a cleaning solution. Mix a mild detergent or a specialized roof cleaning product with water according to the manufacturer's instructions. Apply the solution evenly to the affected areas and let it sit for a few minutes to loosen the moss and algae.
Pressure washing: Once the pre-treatment has had time to work, start pressure washing the roof tiles. Begin from the top and work your way down, applying the pressure washer's stream at a downward angle. Maintain a safe distance from the tiles to prevent damage, usually around 6 to 12 inches (15 to 30 cm) away. Move the nozzle in a sweeping motion, covering the entire surface of the roof tiles.
Stubborn areas: For stubborn moss or algae spots that are harder to remove, you may need to increase the pressure or use a rotating scrub brush attachment specifically designed for pressure washers. Be cautious not to apply excessive pressure that could damage the tiles.
Rinse thoroughly: Once you have pressure cleaned the entire roof, rinse off any remaining detergent, moss, or algae residue. Use the pressure washer to spray clean water over the tiles, again working from top to bottom. Make sure to remove all traces of cleaning solution.
Post-cleaning inspection: After rinsing, inspect the roof tiles to ensure all moss and black algae have been removed. If you notice any remaining spots, you can repeat the pressure cleaning process or consider manual removal using a brush or scraper.
Remember, pressure cleaning should be done with caution, as excessive force or incorrect techniques can cause damage to the roof tiles. If you're unsure about the process or have a particularly delicate roof, it may be best to consult a professional pressure cleaning service or a roofing specialist to ensure the job is done safely and effectively.

Is there something special to spray on terra cotta tiles to help to stop mold coming back after pressure cleaning? Thanks. Just noticed you mentioned using a "post clean barrier". What would that be?

[@colhansen]

@@samcopaintinganddecorating You mean after cleaning spray 30 SECONDS every now and then to keep the mold away. Only problem with tanks I like to hose the terracotta roof off well before connecting the tanks again. I guess it would be good to leave it on after spraying every now and then.

Can i wash my tile roof with a 290 bar/4200 psi. 15 lpm pressure washer? Or will it be too small? Will it loose pressure when washing 5 meters up?

[@samcopaintinganddecorating]

I use 280 bar 5 met shooed be ok

[@DrVexer]

So far I've been told over and over that you should never spray up the roof always down. But it seems you spray up a few times. Has this ever become an issue for you?

[@samcopaintinganddecorating]

Hi mate, it's never been an issue, if the washing is done at about 45*degrees angle then no water should go under the tiles and you need to be on the move constantly as if you stay on 1 spot for a longer time then water will accumulate obviously- so back and forth motion is essential! THIS IS THE BEST WAY TO CLEAN THE EDGE OF THE TILES AND TO GET RID OF ALL THE DIRT, MOSS AND ALGAE ACCUMLATION. I hope this answer your question, give it a try next time👍

[@christopherhayward98]

Hi Samco, How long did you leave the treatment on before pressure washing? Did you use spray and walk away as the pre treatment?

[@samcopaintinganddecorating]

Hi thank you for watching YES spray and walk away for 15 h

How is the pressure washing different than soft washing? Are you using a lower psi? Would love to know. Thanks for the vid!

[@samcopaintinganddecorating]

Yes, correct lower psi

[@JoGmummy]

Hi thanks for the video, do you mind if I ask a couple of questions please? What spray gun are you using for the treatment? Also, would you use the same gun to treat a roof and then to paint a roof? (Obviously cleaning the gun in between) or do you have separate guns? Thanks jo

[@samcopaintinganddecorating]

Hi Jo, To spray on treatment, I have used a garden sprayer for chemicals, easily find in a hardware store and to wash the tiles you'll need an actual high pressure gun. I hope this helps, I saw post your post just recently :)

Is that CH you put in beforehand?
