The roof is finally complete! The building is fully enclosed so there shouldn't be many more weather delays. The new Co-op is going to be a one story building with a "flat" rubber roof membrane, with a 90 mph rating at the lakeside edge. Flat is in parenthesis because it slopes to drains on the roof to avoid standing water, and this will help avoid having water pouring over the roof onto the walkways and customers.
We decided to go with a flat roof to allow a second story at some future date. We have maximized our lot so if we decide to expand in the future, going up is the only solution - besides moving to a different location. I know that it seems to be premature to talk about future expansions, but it is good to be prepared. The building is designed and engineered to allow a second story so we're ready for whatever the future may bring.
