Can you pressure wash a conservatory roof.
How can i clean my polycarbonate conservatory roof.
If you ve missed any spots now is the time to go over them with a small sponge and water.
The strong jet of water can break the seals of the glass and cause leaks.
It is better to use a garden hose to remove any soap and debris.
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.
The pressure washer while it will get the roof clean will also damage the seals of the glass or plastic roof panels.
If it s glass you can use a pressure washer but watch out for the ridge which may be vented.
Many people think that is okay to pressure wash a conservatory roof but it actually isn t.
That s because these tiles are made of granular concrete and the pressure will actually degrade and wear them away significantly.
If the roof is polycarbonate use warm soapy water with a soft foam type mop.
Once you re satisfied with all of your work then you can rinse off the roof with a pressure washer and some clean water.
Rinse off with a hosepipe.
This results in the roof springing leaks.
