You ca ask him anything at all – whether it is directly related to roof repair work or not.
But you must be PRECISE in your prompts – because Jack can give you misleading answers if you ask ambiguous questions.
And if you ask too many questions – Jack will get very tired
Hi Jack, my roof does not have any sarking. I have lichen on it and contacted an exterior cleaning company to pressure clean my roof. They will not do it because of fear of water ingress as I do not have sarking. Is this true? Because in the past we have had severe heavy rain. I don’t see the difference?
Hi Kim,
The two main differences with high pressure water cleaning and normal rain is:
1) There is a huge difference in water pressure between rain and high pressure cleaning. When the stream of water from the ‘gun’ is aimed at the joints between the tiles, it will force water past the lap. It is like the difference between someone stroking your face and a slap.
2) The angle of the water stream: Rain is mainly vertical of in extreme cases, 30 to 45 degrees to the tiles. The tiles are designed for these cases.
When high pressure cleaning is carried out, the angle of the nozzle varies a lot and there is a tendency to push water past the laps of the tiles – because tiles are not designed to have water attack it from all directions.
I have come across many cases of home owners experiencing major leaks during high pressure cleaning. Even roofs with sarking get leaks.
Hello Jack,
Do you happen to speak mandarin? My roof is in need of some repairs and it is hard to discuss with my mother since my mandarin is not the best… I have already booked an inspection for this Thursday (14/09).
Hi Fu,
Thanks for booking your inspection on our calendar.
I don’t speak a word of Mandarin.
But I can point and nod.
Jack
