Thank you for your response to my request regarding the re-roofing of my garden shed. Followed your advice and used butyl sheet. Great idea, looks good and should last for many years. Many thanks.(only downside, roof now looks too good for the shed its on!)
A bit of positive feedback......much appreciated....
Last week I was talking to the guy who told me about Butyl Rubber...he said he used it on his own extension 33 years ago ... and it's never give a problem since.
But if your shed gets blown over..... dont come complaining to me .... ;-)
