Mike Holmes and his team get on top of a bad roof that has plagued a family for 40 years. The damage Mike uncovers proves they have been coping with leaks for nearly half a century. There’s mold in the attic, barely any insulation and as a result, heat loss like Mike has never seen. Mike and his team conquer the scorching heat and accomplish their mission, re-engineering a truss roof into a custom roof. Through the process, Mike demonstrates that building a roof right protects everything underneath it – and that’s what counts.
