Size and pitch
A larger roof needs more material and more labor. A steep roof is slower and more dangerous to work on, which adds cost.
Material
Asphalt shingles are the most affordable. Standing seam metal costs more up front but lasts much longer. Slate and tile are premium materials and need structure that can carry their weight.
Tear-off and disposal
Removing one layer of old roofing costs less than removing several. Disposal is part of the job.
Decking condition
Damaged or rotted decking has to be replaced, and it is often only visible once the old roof is off. A good estimate explains how this will be handled.
Complexity
Valleys, dormers, chimneys, skylights and multiple roof levels all take more time and more flashing work.
Getting a real number
Because every roof is different, no article can give you an accurate price. A free inspection and written estimate shows what your roof needs and what it costs.
