You want spray foam insulation in your attic, but you’ve heard through the grapevine that it will void the warranty on your shingles.
This honestly depends on the company that you purchased your shingles from. Some people think that spray foam in your attic will damage the shingles, but that’s not the case. It is this way of thinking that leads some manufacturers to add this clause in their shingles warranties.
