Advice on replacing garage roof
Options

Hi,
I'm looking for some advice about replacing my garage roof. Currently it is constructed with several corrugated bitchumen sheets, centered with transparent plastic (I think PVC) sheets. These are supported with a few unequally spread wood beams. As you can see from the photos, over time there has been a build up of rainwater on several of the sheets which has caused them to badly bow to the point where the bitchumen is now torn and in desperate need to replacement. One of the sheets was replaced about 7/8 months ago and has already started to bow.
I had someone out today who recommended fibreglassing the roof and indicated that it would cost £2k+ for parts and labour, but this is quite a bit more than I was hoping to pay. I'm considering having ago myself. Would an option be to take off the existing sheets, put down some plywood/OSB3 sheets to strengthen the roof and then put down some new corrugated on top? Also does anyone have experience using EPDM rubber? I've read mixed reviews about this? Is this likely to be a difficult job?
Any help much appreciated!

Rubber is simple. I just put osb sheets down, make sure they are all even with no steps at the joints, then apply adhesive & rubber. The suppliers usually have good instructions or there must be YouTubes about it.Tall, dark & handsome. Well two out of three ain't bad.1

Thanks. Out of interest, what depth did you use for the OSB? I've read varying reports about the lifespan of rubber and that it can warp in the heat, how long have you had yours?EssexExile said:Rubber is simple.

EPDM is so easy, I did my kitchen roof in it. I used the thinner sheet, I think it was around 1.1mm.
It has been in place for 6 years now and still looks brand new.
When you put it down you can see that there are just not going to be any leaks again.1
