I have a small roof 10'x10' which needs new covering. I now has the standard asphalt 'roll-o-roof' which is just not doing the job. The roof has a small bit of people traffic and this causes the asphalt to quickly get worn away. I remember seeing a previous HomeAgain show which had a project which Bob used rubber roofing membrane and glued it down to plywood decking. Anyone have a source, in Canada, for something simular to this?
