We are building an extension to the back of house that increases the size of an existing flat roof extension. Our builder has suggested a nordic?/ nordman? roof which is fitted in one piece, replaceing existing flat roof and covering new extension. This is adding considerable to the cost. Does anyone know anything about this type of roof? Also, is it worth the extra cost? And, if not what are our options?
Many thanks
