Roof Replacement (Asphalt Shingles) Cost in 2026: What to Expect

Roof size is the single biggest cost driver. A 1,500 sq ft roof might cost $5,250-$10,500, while a 3,000 sq ft roof doubles that to $10,500-$21,000. Roofing is priced by the 'square' (100 sq ft), with each square running $350-$700 installed for standard architectural shingles.

Basic 3-tab shingles run about $4 per square foot installed ($80-$100 per roofing square for materials alone). Architectural shingles - the most popular choice - cost $5-$7 per square foot ($100-$200 per square). Designer or luxury shingles push $8-$10 per square foot ($200-$500 per square). For a 2,000 sq ft roof, upgrading from 3-tab to architectural adds roughly $2,000-$6,000.

A simple gable roof with a walkable pitch (4/12 to 6/12) is the easiest and cheapest to work on. Steep roofs (8/12 and above) require special safety equipment and slow the crew down, adding 20-40% to labor costs. Multiple dormers, valleys, hips, and skylights also increase complexity and cost.

Most building codes allow a maximum of two layers of shingles. If your existing roof has one layer, tearoff is standard. Two layers means more labor and disposal costs - each additional layer of tearoff adds $1,000-$3,000 to the project. Some municipalities require a full tearoff regardless.

Once old shingles are removed, the plywood deck underneath may show rot or damage. Replacing damaged sheathing runs $2-$8 per square foot. On average, expect 1-5% of your deck to need repair, but badly neglected roofs can need 20% or more replaced, adding $500-$3,000+ to the job.

“Are you licensed, insured, and do you carry workers' compensation?”

Why this matters: Roofing is dangerous work. If a worker falls on your property and the contractor lacks workers' comp, you could be liable. Verify their insurance certificate directly with the insurer.

“How do you handle deck damage discovered during tearoff?”

Why this matters: Damaged sheathing is common but hard to predict before tearoff. You need a clear per-square-foot price for deck repairs agreed on in advance, not a surprise change order.

“What warranty do you offer on labor, and what does the manufacturer warranty cover?”

Why this matters: Shingle manufacturer warranties cover material defects (often 25-50 years) but NOT installation errors. A separate 5-10 year workmanship warranty from your contractor is critical.

“Will you pull the permit and schedule the inspection?”

Why this matters: A reputable roofer handles permits and ensures the job passes inspection. Skipping permits can cause problems when you sell your home or file an insurance claim.

“What is your cleanup process?”

Why this matters: Roofing generates a lot of debris - old shingles, nails, and packaging. Ask if they use tarps to protect landscaping and run a magnetic nail sweep of your yard and driveway.

“How do you handle weather delays?”

Why this matters: Roofing is weather-dependent. You need to know their plan for protecting an exposed deck overnight if rain moves in mid-project.

“Can I see your roofing license number and three recent local references?”

Why this matters: Many states require a specific roofing license or registration. Local references let you drive by and see the contractor's work in person.
