Roof-Over Cost Calculator

A roof-over installs a brand-new layer of shingles directly over your existing roof instead of tearing the old one off. In the Tulsa area it typically runs $5-$9 per square foot installed - roughly $12,650-$22,770 for a 2,200 sq ft home at an average pitch.

Sometimes, but not always. Full tear-off replacement runs about $4.95-$6.85 per square foot in Tulsa including disposal, so the pricing overlaps. The real roof-over advantages are speed (1-2 days versus 3-5) and skipping tear-off debris - not a guaranteed dollar savings.

No. Oklahoma follows the IRC, which caps residential roofing at two layers. If your roof already has two layers, a roof-over is not permitted - the old roofing must be torn off before a new roof can be installed.

Generally no. After a covered hail or wind loss, Oklahoma carriers pay for full tear-off and replacement so the new roof meets code and hides no damage. A roof-over after a storm claim can jeopardize coverage - if you have storm damage, call (918) 734-4444 for a free inspection before roofing over anything.

The new shingles carry the same rated lifespan either way (25-30 years for architectural). The difference is what is hidden underneath: a roof-over keeps your old deck and underlayment in place, so pre-existing deck rot or leaks stay buried. Full replacement exposes the deck so it can be repaired - which is why we recommend it for aging or storm-damaged roofs.
