Roof Cleaning Issues: What Can Go Wrong When Cleaning My Roof
Insights from a 27-year experienced roof and exterior cleaning company based in Abingdon, Oxfordshire
Considering Roof Cleaning
When contemplating roof cleaning, remember that your home is one of your biggest investments. You wouldn’t let your car get dirty, moldy, and covered in algae, so why allow your home to become grimy? Ensure you hire a company with an established history and experience in roof cleaning. Inexperienced companies may use 3000psi high-pressure jet washing, leading to potential problems.
The Right Cleaning System
Stonehealth sells the DOFF system, which uses 900psi, 7lt per min at 150oC hot water. In comparison, this pressure is about half that of a Karcher pressure washer used to clean cars or patios. Pre-clean pressure should not exceed 900psi, as higher pressure may damage your roof tiles.
Uncovering Issues During Cleaning
During the cleaning process, existing issues on your roof may be uncovered. If you’ve had previous roofing work or repairs, roofing companies may have matched the tile style and profile, but not the color. Roof cleaning can reveal these inconsistencies.
At the home assessment, the roof may be covered with moss, algae, and lichen, and cleaning problems might not be visible until the process begins. An inexperienced roof cleaning company could cause more damage by walking on the roof and breaking tiles or causing leaks around Velux roof lights. Ask how the company plans to keep gutters and downpipes from getting blocked.
Choosing the Right Roof Cleaning Company
When looking for a roof cleaning company near you, ask for examples of their previous work on homes similar to yours. Inquire about their review platforms and check them out. Request information on local work completed so you can see the results for yourself. Consider if the company is local, as this ensures they can promptly address any issues that arise.
Examine their social media feeds for an indication of the work they do. If they haven’t posted in weeks or months, be cautious (Caveat Emptor – buyer beware).
In Conclusion
To avoid potential roof cleaning issues, choose a reputable and experienced company that uses the right equipment and techniques. By doing so, you can protect your home and investment while improving its appearance.
