Back in the 1960’s; 1970’s and even the 1980’s it was fashionable
for roofs of out-buildings and sheds to have a covering of
corrugated roofing sheets, which usually meant an Asbestos Roof.
This was especially popular for your garage roof.
The main reason was it was just about the cheapest
covering that was available
for an economic roof construction and it was so easy to fit.
There were other advantages, mainly it was light weight
and the corrugated roofing sheets
absorbed noise such as the rain landing on it.
The acoustic advantage was due to the roof construction and the shape
effect of the corrugated roofing sheets
Have you ever sat in a conservatory with a Polycarbonate roof and
listened to the rain?
Did it sound like “The End Of The World?”
In a shed with an asbestos roof, you have to
hold your breath to hear the rain
If you sat in a shed with an asbestos roof, you would have to
hold your breath to hear the rain even in the most violent storm.
Asbestos sheeting looked stark when it was new and it soon deteriorated
to become a complete eyesore
This was mainly because of the moss it encouraged to grow on the porous surface
of the Cement Bonded Asbestos Sheets
Now in the 2010’s people don’t think about what it looks like;
they just get emotional about the ‘A’ word
In truth, let me put your mind at ease; the most dangerous thing about
Asbestos Cement Sheeting on your Garage Roof, is the risk of
falling through the sheets if you are foolish enough to walk on them.
For those of you who are interested in the technicalities;
the asbestos content of these sheets is generally
less than 5% and that small amount is totally bonded in cement
