Roof size is only the starting point
The total roof area, pitch, number of slopes, valleys, dormers, skylights, chimneys, and access all affect labour and material needs.
A simple bungalow roof can price very differently from a steep multi-plane roof with several flashing details.
The hidden variables matter
Decking repairs, old layers, ventilation corrections, drip edge, ice and water shield, and disposal can change the quote.
A competitive roofing quote should make these variables clear before work starts.
Cheapest is not always comparable
Compare what is included. If one quote omits flashing, ventilation, underlayment, disposal, or cleanup, it is not the same scope.
