Black Roof

Why do I need to clean my roof?
 

✅ Preventing Tile Damage: Dirt, debris, moss, and algae can accumulate on roof tiles over time. This buildup can trap moisture, leading to the growth of moss, algae and lichen which like to feed on limestone, a key component of most roof tiles. Ultimately weakening them.
 

✅ Preventing Water Damage: Clogged gutters and downspouts resulting from debris buildup on the roof can cause water to overflow, leading to water damage to the roof, siding, and foundation of your home. By keeping your roof clean, you reduce the risk of water pooling and causing damp issues in your home.
 

✅ Maintaining Appearance: A clean roof enhances the curb appeal, and the value of your home.
 

✅ Improving Energy Efficiency: Dark stains on roof tiles can absorb more heat from the sun, leading to increased temperatures in your attic and home. This can result in higher cooling costs during hot weather. Cleaning the roof tiles helps maintain a lighter color, which reflects more sunlight and keeps your home cooler, thus improving energy efficiency.

Overall, cleaning your roof tiles is an essential part of home maintenance that helps protect your investment, maintain your property's appearance, and prevent costly repairs down the line.


How We Clean A Roof

Our cleaning methods follow the guidelines set out by the Roof Tile Association. The RTA represents the UK's leading manufacturers of pitched roof solutions.

One of the most common methods of cleaning roof tiles is to high pressure wash them. However, this is advised against by the Roof Tile Association as using pressure that is too high can do more harm than good. Another common method is manually scraping the moss off, however this is also advised against by the RTA. The finish on roof tiles, which is normally a granular finish, is there to protect them and gradually wear off over time. Too much pressure and manual scraping can remove the top layer of granular material from the shingle or tiles, the older the tile, the more likely this granular loss will occur.

We choose to clean most roofs with a surface cleaner and our pressure washers set to the minimum pressure, followed by a biocide treatment. Once we have removed as much of the organic material as we can without turning the pressure up, the roof is then treated with a biocide which will kill off any remnants and will prevent new growth in the near future. We also offer biocide treatments independently of a full clean should you wish to keep your roof clear of growth.
