I live in Southern Oregon. The climate here is pretty normal. 100 in the summer and 25-30 in the winter. Recently we have had 40 mph wind storms which so far have caused three shingles to blow off. Now, the house is about 8 months old, but we purchased it about 3 months ago. Under Oregon law, it has a 1 year warranty. I was wondering if the builder (which did a half a** job on a lot of things) incorrectly installed the roofing (looks like fiberglass shingles that were stapled down). I don't want to imagine what the roof would be like in 5 years if this is happening so soon. What are your thoughts?
