It’s the first question almost everyone asks — and it’s also the hardest to answer without seeing the house. Here’s why: every roof is different. Unlike a car that rolls off an assembly line identical to the one before it, roofs vary house to house. Four factors drive the price.
Size
Roofs are measured in squares. One square is a 10’x10′ area — three bundles of shingles. A 20-square roof with standard pitch and low complexity starts around $8,200 in the Tulsa area. A 40-square roof with the same pitch starts around $16,400. Both prices include a full tear-off and all new components.
Pitch
There are five pitch categories: Flat (0/12-3/12), Low/Standard (4/12-6/12), Medium (6/12-9/12), Steep (10/12-11/12), and Very Steep (12/12 and above). Low/Standard is the least expensive. The steeper the pitch, the slower the work pace — and the higher the labor cost. A steep or very steep roof can add 20-40% to your base price.
Shingle Type
Three-tab shingles are the cheapest but only rated to 60 mph — not recommended in Oklahoma. Dimensional or architectural shingles are the base model we recommend. Impact-resistant shingles cost more upfront but can qualify you for a discount on your homeowner’s insurance — worth asking your agent about before you decide.
Building Codes
Codes vary by location. Ventilation upgrades alone can run from $500 to several thousand dollars. A reasonable budget cushion is $1,000-$2,000 on an $8,200 roof and $2,000-$4,000 on a $16,400 roof for code requirements or material upgrades.
