We’ve recently finished building our custom home which we oversaw all of the trades, made sure we used the best in the city.
Our home has a flat roof with an unvented attic which has been spray foamed. The flat roof is not parapet and uses the conventional gutter and downsprout drainage. We began noticing ice building up underneath the soffits during the Winter months. It got to a point where during warmer Winter days we had leaks through our potlights. We ended up losing many of the lights as they flickered and then burned.
My roofer has been by several times doing water tests since and telling us that the problem is not the roof but that it may be condensation due to the change in temperature between the sprayed insulation in the cavities and the outside weather.
I should add that the insulation company we hired did not used board stoppers when they wanted to spray the cavities to the outside and only used pink insulation during the spray.
This issues has resulted in the formation of mold on the rim board and headers and we’d like to know the source as our experience with our new home has been somewhat ruined.
Any input would be greatly appreciated!
