Help Iris patch the roof before the autumn rains

I'm a disabled veteran living in Amsterdam. During the last storm water started coming through the ceiling in 3 places, and the living room is no longer usable. A roofer quoted $2,600, which isn't something I can pay. The good news: a local hardware store has donated the tiles and battens. What I don't have is people to do the work. I'm looking for three or four volunteers who can help over a weekend. Experience helps, but it isn't essential - I'll have a licensed roofer supervising for safety. All you need is work boots and a hat. I'll provide lunch, water and lots of thanks. The work will be done on the ground and roof with proper harnesses. If you can only help for a few hours, that's welcome too. Thank you for reading my story.
