Thanks guys for persuading me not to do a layover on my house, which has dimensional shingles. I have a barn that has 3 tab shingles and I am going to get a second layer of 30yr laminate put on.
My question is how much difference should I be charged for just a layover instead of a tear off. I have a guy that said he will charge me $140/square on a tear off for my house and $110/square for a layover on my barn. Neither has much of a pitch. The shingle to be put on is an Elk 30yr laminate.
