How much does a new roof cost in Lancaster County?
Across the 967 asphalt roof replacements we sold from November 2024 to October 2026, the median price was about $12,900. The middle half ran from about $8,800 to $17,200, and 9 in 10 came in under $23,600. Smaller and simpler roofs land at the low end; large, steep or cut-up roofs at the high end. Only an on-site measurement gives your exact price.
What does a roof cost per square?
Roofers price by the square, which is 100 square feet of roof. For CertainTeed Landmark architectural shingles, the jobs we sold from November 2024 to October 2026 had a median of about $710 per square, including waste, and the middle half ran from about $610 to $890 per square. Steep pitches, extra layers to tear off and decking repairs push a job toward the top of that range.
What does a metal or flat roof cost?
The metal roofs we sold from November 2024 to October 2026 had a median of about $18,200, with the middle half between $8,100 and $25,100; we sell few metal roofs, so treat that as a rough guide. Flat and low-slope roofs had a median of about $9,000, with the middle half between $5,800 and $14,300.
What makes a roof cost more?
Steep pitches need extra safety equipment and go slower. Dormers, valleys, chimneys and skylights add flashing work. A second layer of old shingles adds tear-off and disposal, and replacing rotted decking found during tear-off adds cost. Ventilation upgrades add cost too, but poor ventilation is the top reason manufacturers deny warranty claims.
Will insurance pay for my roof?
If hail, wind or a fallen limb damaged the roof, your homeowner’s policy usually pays for the repair or replacement minus your deductible. Wear and age are not covered. Our HAAG-certified inspectors document the damage, and we work with your insurance company directly.
Do I have to pay a deposit, and can I finance the roof?
No deposit is required; you pay when the project is complete. Financing is available through Enhancify and Service Finance. Rates and terms come from the lender, and current options are on our roof financing page.
What should a roof estimate list?
A clear estimate names the shingle line and color, the underlayment, ice and water shield, ventilation, flashing, how decking repairs are priced, permits, disposal, the schedule and both warranties. If any of those is missing, ask before you sign so you know what you are paying for.

WHAT AFFECTS YOUR FINAL COST
Additional Factors That Impact Pricing
Roof Complexity and Pitch
Simple gable roofs cost less to replace than complex designs with multiple angles, dormers, and penetrations. Steep pitches require additional safety equipment and slower installation, increasing labor costs.
Tear-Off Requirements
Removing existing shingles adds $2–$4 per square foot to project costs. Complete tear-off allows proper inspection and preparation of the roof deck, and is usually worthwhile.
Structural Repairs
Damaged roof decking, fascia boards, or structural elements discovered during tear-off must be repaired before new installation. These repairs typically cost $3–$8 per square foot depending on extent of damage.
Ventilation Systems
Adequate ventilation costs $500–$1,500 but is essential for roof performance and energy efficiency. Poor ventilation voids most manufacturer warranties and leads to premature material failure.
Ice and Water Barriers
Enhanced ice and water protection costs $2–$4 per square foot but prevents expensive water damage during ice dam conditions common in our region. Building codes in PA, NJ, and DE require ice barriers.
Permits and Disposal
Building permits typically cost $100–$300 depending on location. Disposal fees for old materials range from $500–$1,500 based on roof size and local dump fees. These costs are essential parts of professional roof replacement.
