For tougher stains, such as mould or mildew, consider a turbo nozzle. This attachment combines a high-pressure stream with a rotary action, making it more effective against these stubborn residues without needing to increase pressure settings.
It’s crucial to avoid narrow nozzles, like 0-degree tips, as they can create concentrated, high-pressure streams that may lead to shingle damage or even dislodgement. Always test in an inconspicuous area first to ensure compatibility with your roofing material.
If you are working with softer materials, such as asphalt shingles, adapt your approach by utilizing a lower pressure setting along with a wider spray angle. This combination provides thorough coverage without risking surface integrity.
Lastly, consider using a cleaning detergent suited for roofs in conjunction with the right nozzle. Applying the solution through a soap nozzle enables better penetration of grime, and rinsing later with a wide-angle tip will ensure an even finish.
Optimal Pressure Settings for Different Roof Types
For asphalt shingles, I recommend settings between 1,200 and 1,500 PSI. This range effectively removes algae and debris without causing damage to the delicate material.
When dealing with tile roofs, adjust the machine to about 1,500 to 2,000 PSI. This pressure efficiently cleans while preserving the integrity of the tiles, which can be brittle and sensitive to excessive force.
Metal roofs generally withstand higher pressures; thus, 2,000 to 3,000 PSI is suitable. This level effectively eliminates dirt and other contaminants without compromising structural integrity.
Wooden roofing requires careful handling. A setting of 1,000 to 1,200 PSI is optimal to avoid stripping away protective coatings or damaging the wood.
General Guidelines
