This is why jet washing a roof is USELESS 😭👇
It looks brilliant for the camera.
Years of dirt disappear in seconds, dirty water everywhere, instant before and after…
But there’s a reason we’d rather scrape the heavy moss off by hand and treat the roof afterwards.
A jet washer is aggressive and can force water into places you really don’t want it, especially if the roof already has damaged tiles, weak pointing or other defects.
Scraping also means we’re actually on the roof inspecting it as we work. 👀
Cracked tile? We see it.
Loose ridge? We see it.
Problem around the flashing? We see it.
Then once the bulk of the moss is removed, we clear the gutters and apply a biocide treatment to tackle the remaining biological growth and help slow regrowth.
But apparently taking longer and doing it properly is “old fashioned” now 😂
Roof cleaners, I already know what the comments are going to look like…
JET WASH or HAND SCRAPE? 👇
