We had some strong winds last night and I lost a 3 foot by 1 foot section of shingles off my roof, I found it in my yard this morning. It was too dark to see anything else up there but my wife called later and said she thinks she saw some other loose shingles still up there. About how much should it cost to get these resecured? I do have some extra shingles in my garage but I don't have the ladder (or the skill) to do this job myself.
