Anglicans in Guelph: Facilitator's Report

Update on the Roof with Engineering Report (from David Kupp)

On balance: adding up the plus's and minus's, it appears that redoing the flat roof is the winner, as opposed to adding a sloped roof with trusses and steel cladding. 
The highlights of the report, as I read them:
1.  the short and long-term costs are not significantly different between the flat and pitched roofs options.  Initial costs are approximately $10-20,000 less for the flat roof. 
2.  the energy upgrading -- both roofs can be insulated to the level required
3.  the current roof is at the end of its useful life
4.  replacing the current flat roof with an upgraded flat roof will reduce the weight on the current roof structure
5.  the new flat roof can be pitched to eliminate water ponding, and the drainage system can be improved
6.  the new recommended flat roof would last 20-25 years, but it can then be renewed with the addition of another membrane for 15-20% of the original cost.  Each membrane renewal lasts another 10-15 years.  However, a pitched truss roof with metal roofing tiles also requires maintenance and renewal (painting) periodically. 
7.  During design and installation of a pitched-roof truss system, further engineering work would be required to determine wind load and timber structural capacities
8.  The pitched truss roof option requires full redesign and installation of water flow, and consideration of ice issues.

Unfortunately, IRC has also confirmed that the "new" roof over the foyer/entrance area is poor quality, and may only last 3-5 more years.

One additional thought:  the roof of D&P is ideally suited for solar panels, and we could get a free assessment of the possibility of joining the Ontario FIT program, which would ultimately provide some revenue for D&P, for 20 years.  I can arrange a free assessment, if you're interested.  Redoing the roof is the perfect time to at least install the framework for future panels.
