Thanks in advance to anyone who resonds. Two years ago we bought a home with a 6 year old roof, that we surprisingly found out was defective / not installed properly. Unfortunately the roof leaked during our first year so we had the whole thing replaced - plywood and new shingles - the following spring (2010). We chose the CertainTeed Landmark 50 shingle and went with a reputable roofing contractor. I know that we had a rough summer and winter (live in PA), but I am now noticing that roof edge coming down along the garage and coming down along our A-frame section of the house in the back is 'lipping up' (probably not the correct term) as it goes from the middle of the roof to the edge. I climbed up to the edge with a ladder and put a 4 foot level from the edge in, and there was about a two inch gap in the middle of the level. The odd part is as I inspected the underside of the shingles along the edge, they appear to be tight to the decking/metal edging. Does anyone know if this is normal or should I be concerned? Any advice would be appreciated.
