Roof geometry and removal
Measured roof area, pitch, stories, valleys, dormers, penetrations, existing layers, and disposal influence labor and material.
System components
Underlayment, flashing, ice and water protection where required, ventilation, accessories, and warranty level belong in the comparison.
How to compare estimates
Compare inclusions, material specifications, decking allowances, change-order policy, cleanup, permits, and warranty—not only the bottom line.
