Advice on replacing corrugated bitumen garage roof

Postby Rossy_87 » Mon May 25, 2020 4:13 pm

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!

Hi rossy_87
Unfortunately your photo in not accessible however I would suggest you replace the roof with corrugated steel sheets.
