Those who can sign up for the different programs get a badge/sticker with different metal colors.

Still waiting to hear back from him, but his work will include: repairing a few sections of roof, reshingling one side of the mansard roof, metal capping all window trim, replacing a few broken window sashes, getting screens made for all windows, routing gutters to the appropriate drains.Progress has been slow because I only get a few hours in a few days per week after my school day.

Plus he says I have to raise limits for my car insurance to $500K/$500K/$500K for bodily injury and property damage liability from the standard limits required by lease.

Metal in the valleys with mastic. 

I am just not sure how it will look after the roofers install metal coping etc there, or they would be careful about "aesthetic" details :)Exterior/wood is also deteriorating, but I guess a painter can scrape the old paint and caulk for waterproofing.
