Garden Shed Roof Replacement with Suntuf Panels http://www.durgan.org/URL/?BNPIX 21 September 2009 Shed Roof Replacement with Suntuf Panels. In 2004 a shed was build and typical PVC panels were used for the roof. Similar to Palruf, but am not certain of the name at this time. It may even had been Palruf. This was desired for having ample light in the shed. The material went through about two seasons then it got brittle and cracks appeared. Clearly this material is almost useless for building. The roof was replaced with Suntuf, which is supposed to have a long life and is UV resistant. Both products appear flexible and strong when new. Suntuf is about $50.00 for a 2 by 12 foot sheet, whereas the old PVC panel is about $30.00 for a similar sized sheet.
