About 3 years ago I had a massive failure on my workshop roof, the hot weather caused many cracks in the cement board roof, which was about 10 years old. I tried to cover and seal the cracks, but six months later it was failing again and the weather wouldn't permit any further repairs.
It really needed a new expensive roof, but it would have meant taking down all the internal ceiling and insulation, leaving my shop open to the elements, plus lots of disruption.
So to do a temporary repair I took the side of a wagon curtainsider and draped it over the roof. It worked OK, but it really needed a permanent solution.
This is how the roof looked first thing this morning.
A couple of chaps with big paint brushes soon had the roof thickly covered in a glass filled two part resin.
The new roof now, guaranteed a minimum of ten years against leakage, and if any splits appear under the layer, the resin skin will expand up to 10mm to cover them.
So now I can forget about the roof and get back to work in my shop in the knowledge that I am watertight again.
