Raise the Roof!

Now that school is out for the year, I've got a friend who's a teacher coming over to give me a hand with my roof. He does roofing & siding jobs in the summer as a way to keep his wife happy with the extra income. Actually, it supports his golf habit. I'm expecting to remove two layers of shingles, which should be fun. I know there are two small leaks to deal with, one in the garage (water slowly drips onto the concrete floor - not a big worry) and one around the chimney (no showing water damage inside, but there is evidence of a leak when you look from in the attic). I'll add a full ridge vent and remove some unneeded vents on the back of the house. I'll also add at least one tube-light (similar to a skylight) to help light the hallway and probably another for the main bathroom. The gutters need to be re-hung as well to make them flow properly, so this is as good a time as any to do that.

I'm willing to bet that the roof has never had shingles removed. Figuring that most shingles have around a 20-25 year life, and the top layer looks to be at least 25 years old, that would account for everything on the roof right now. The top layer is pretty brittle and curling in spots, so I hope it comes off easily...
