Pitch and access
Steeper roofs require more safety setup, more labor time, and often more waste.
Tear-off layers
Old shingles, decking surprises, and disposal fees can move the final quote.
Valleys and penetrations
Chimneys, skylights, pipe boots, vents, and valleys add flashing detail and labor.
Material grade
