The Roof Repair Cost Calculator uses industry-standard pricing to estimate repair costs.
$$\text{Total Cost} = (\text{Material Rate} \times \text{Damage Factor} \times \text{Pitch Factor} + \text{Removal Cost}) \times \text{Area}$$

4.50 dollars/ft² (asphalt)4.50 dollars × 1.25 = 5.63 dollars/ft²5.63 dollars × 1.1 = 6.19 dollars/ft²6.19 dollars + 2.00 dollars = 8.19 dollars/ft²8.19 dollars/ft² × 1,000 ft² = 8,190 dollarsA damaged or leaking roof can be overwhelming and should be repaired urgently. Are you wondering how much it will cost to fix your roof? Our Roof Repair Cost Calculator is designed to help you estimate repair costs based on your roof’s specifications.
In this guide, we will cover:
A Roof Repair Cost Calculator is an online tool that takes inputs—roof area, material, damage level, pitch factor, and removal cost (if you need to remove old materials)—and computes an estimated total cost. You can also enter a custom rate per square foot if you have a local contractor quote for greater accuracy.
The calculator is designed to be easy to use. Simply provide a few key inputs:
1,000 ft²).Asphalt Shingle, Metal Panel, Tile, Wood Shake, EPDM Rubber, Slate, TPO/PVC Membrane, or Composite.Minor", "Moderate", or "Severe".Low pitch (easy), medium pitch (standard), or steep pitch (require extra time and safety measures!).Use Custom Rate” and enter your rate—removal costs still apply.Are you curious to know which formula is used to estimate the total repair cost based on several input values? We're going to discuss a real-world example that will help you understand how the roof repair cost is calculated—and also guide you on how to calculate it manually.
Suppose you have a house that requires repair, so here detail:
1,200 ft²Metal Panel ($8.25/ft²)Moderate (×1.25)Steep (×1.3)$2/ft²Let's compute the values to get total repair cost:
$8.25 × 1.25 × 1.3 ≈ $13.41/ft²$13.41 + $2 = $15.41/ft²$15.41 × 1,200 ft² = $18,492So, based on these inputs, your estimated repair cost is $18,492 (at $15.41 per ft²).
Absolutely! National average rates come from real industry data and work well when you don’t have a contractor’s quote. If you do have a quote that’s different, use the hidden “Custom Rate” field to enter your number for a tailored estimate.
Roof pitch is considered important for roof repair because a steeper roof means the repair is trickier and requires extra safety gear and time. That’s why our calculator factors in roof pitch, making the estimate more accurate.
