The strong jet of water can break the seals of the glass and cause leaks.
Can you pressure wash a conservatory roof.
If you re giving the conservatory a fairly rigorous wash from the outside you might want to use a pressure washer or garden hose to rinse the roof properly.
There are actually a number of common roof tiles they it s recommended you never wash with a pressure washer.
Once you re satisfied with all of your work then you can rinse off the roof with a pressure washer and some clean water.
The pressure washer while it will get the roof clean will also damage the seals of the glass or plastic roof panels.
That s because these tiles are made of granular concrete and the pressure will actually degrade and wear them away significantly.

Take care if using a pressure washer on your conservatory.
How can i clean my polycarbonate conservatory roof.
Rinse off with a hosepipe.
If it s glass you can use a pressure washer but watch out for the ridge which may be vented.
Use soft bristled brushes and microfibre cloths when cleaning the conservatory roof to avoid scratching the glass or frames.
If you ve missed any spots now is the time to go over them with a small sponge and water.
The trouble is these types of tiles are really common.
If the roof is polycarbonate use warm soapy water with a soft foam type mop.
