Questions about asphalt shingle roof cost.
Why does asphalt roof pricing vary so much?+
Pricing varies because roof size, slope, height, access, tear-off, product selection, decking, flashing, ventilation, disposal, and labor requirements differ from one property to another.
Is damaged decking included in a roof estimate?+
Sometimes. Some estimates include an allowance, while others price decking replacement separately because the full condition may not be visible until removal begins.
Does a more expensive shingle always mean a better roof?+
Not by itself. Product quality matters, but installation, ventilation, flashing, decking, and workmanship are also critical.
Should I choose the lowest asphalt roof estimate?+
Not automatically. Compare material, scope, flashing, ventilation, tear-off, decking, cleanup, warranties, and exclusions before comparing totals.
