Musings on building a workshop and a new machine...

[Iwant1]

I've had all sorts of issues with a flat roof on a garage in the past so don't want a repeat of that. The only issue with plastic coated metal roofing is the noise it makes when it rains hard :

Have you had a look at GRP roofing. I did a roof with a friend of mine as an extension behind his shop. Its uses fibre glass and resin, its easy to put down and has a 30 year life. We didn't put insulation in between the joists, rather OSB3 board over the joists, then 120mm insulation, topped with another layer of OSB3 board, all screwed down with 170mm screws. Planning actually specified which type and size of insulation we needed to use. We had a flat roof with just a rain slope, but it could be installed on a pitch.



Regarding building the super structure, did you ever watch a program called 'Tommy's ultimate workshop' on Discovery Network. He builds a timber structure on concrete foundations. Its a good example of how you could do most things yourself. Each side of the shed is built on the floor then stood up into place. I did this on a small garden shed I made for my brother. Took me a weekend to complete start to finish. Its not a workshop shed, just a stick all your rubbish in shed. I even fixed the cladding to the neighbouring side before I stood it up into place. Didn't want to go to his side to fix the cladding.



You have a Selco's builder merchant near you in Cricklewood, go and just have a browse on the materials you will be needing. They have all the equipment for GRp roofing and even have a demonstration video of how to apply it. Its also a talking point when your mates come to see your handy work, lol. I've found they are also the cheapest supplier of timber, and can ask for discount at the checkout.
