I just had spray foam insulation installed in my cape’s attic. Now I have a number of asphalt shingles that have lifted up. It appears that the expanding foam found its way through some gaps in the sheathing boards and pushed up the shingles.
So my question: Is the insulation contractor responsible for fixing the roof? If not, what’s an easy way to deal with this.

Fanatic,
Around here it would depend on who was responsible for the prep work. I walk the job with the owner of the spray foam company before they do a job for me. He points out "problem" areas and then I get the job ready, this saves him time and me money but I do accept more of the responsibility this way.
He did warn me about lifting shingles, as he had to do some repair work on one of his earlier jobs.
Other concerns are can lights, appliance vents or mechanicals that my need to be accessed at a later date. We usually box off these areas with cardboard of foamboard if the insulation value is critical in the "problem" area.

At someone's suggestion, I went around with a block of wood and tapped some of the shingles back down flat. The foam apparently doesn't have a memory, so this wasn't difficult.
What does appear problematic, however, is that the bottom 2 or 3 sheathing boards seem to have lifted, making the roof bulge a bit near the eaves. Is there a good way to tighten these boards back down to the rafters? I was thinking of just using deck screws and re-shingling that part of the roof.
