Not long ago I was asked to consult the realtor in charge of obtaining proposals for removing a steeple and re-roofing a church in Rochester. He had obtained many bids and there was quite a big price difference between the top and bottom. I looked the project over, took pictures, measured it, and analyzed what a winning game plan might be. Then, I looked at all the proposals. One of the proposals stood out for its outstanding warranty. It was from a roofing contractor that I know of to be very reputable and skilled. There was a common theme amongst all the proposals, though: They all included the bare minimum to meet code.
Normally, that may not be a problem. In this case, my professional advice was that this approach was narrow-minded. As soon as you climbed on the roof, it was plain to see that they had chronic ice dam and water infiltration problems. The 2 valleys had been pulled apart and re-done, and the front one still had electric heat wire in it to mitigate ice damming. Furthermore, the gutter at the bottom of the valley butted right into the adjacent roof plane, preventing water from clearing under it. I determined that this roof required a small heaping of extra effort to ensure problem free performance for another generation.
I suggested to the pastor that he choose the roofing contractor with the great reputation and warranty, but request some adjustments to the proposal. I suggested he ask for Certainteed architectural shingles instead of Iko. Iko shingles don’t hold up nor do they stand behind their warranty, in my experience. I recommended stipulating Grace brand ice and watershield or other non-granular surface product, and I also recommended extending the ice and water shield protection 9’ up the roof line instead of the minimum 6’. This will be absolutelynecessary during heavy snowfall years to avoid water damage from ice dams. Finally, I recommended installing 2 open metal valleys. This would convert the valley from a liability that promotes ice damming to an asset that helps clear ice dams. The open metal valleys really allow water to run and heat up and melt ice in subfreezing weather if the sun hits it.
The pastor said that all of those items were exactly in lock step with what one of his engineer parishioners had recommended. Because his confidence in me was high, he asked me if I would provide a number for the roof project. When I provided a detailed proposal that was $4,000 less than the nearest competitor it was a done deal. Take a look at the finished product.
