Why can two roof quotes be thousands of dollars apart?
Usually, one of them leaves things out.
A complete quote should list:
✔ Tear-off and disposal
✔ Underlayment and ice and water barrier
✔ Ventilation and flashing
✔ Decking price per sheet
✔ Permits
✔ Warranty name and length
A low quote that skips these is a smaller job, not a better deal.
