If your roof is above 7/12 then added cost would be incurred due to the additional challenge and time it will take to install the roof.

Quality of Contractor
We all know that we get what we pay for. At the end of the day when a price is much lower then others it is probably too good to be true.

There are middle size contractors that typically have lower overhead then national contractors but are more reliable then smaller contractors. Then there are national contractors that are typically the most expensive and the other problem becomes customers become a number not a part of the family.
Insurance
When a storm occurs with high winds or hails there are times roofs become damaged. When this happens, it is a home owners responsibility to pay their deductible and the insurance will typically pay for what roofing system and variables you currently have.
