San Diego Roof Cost Estimator
Estimate roof replacement, roof repair, re-roofing, new roof installation, emergency roof issues, and commercial roofing planning ranges using roof size, material, slope, existing roof condition, and visible roof problems.
Estimate Your Roof Project
Select at least one option to generate a planning range. The cards update as more filters are selected. Final pricing depends on roof inspection, material, access, damage, roof details, and project scope.
Roof Cost Planning Ranges by Project Type
The estimator uses roof size, material, project type, complexity, roof slope, visible issues, and current roof condition to create a planning range. Use the table below as a broader reference.
| Project Type | Typical Scope | Planning Range | Main Cost Drivers |
|---|---|---|---|
| Roof Repair | Leak tracing, flashing work, damaged shingles or tiles, flat roof repairs, or small roof trouble spots. | $450–$4,500+ | Damage location, water entry, roof material, roof height, access, and whether decking is affected. |
| Emergency Roof Issue | Active leak, storm damage, temporary protection, missing materials, or urgent water intrusion. | $850–$7,500+ | Active water entry, roof access, temporary protection, damage spread, and material type. |
| Roof Replacement | Tear-off, underlayment, flashing, roof covering, ventilation, cleanup, and deck review. | $9,000–$78,000+ | Roof size, material, slope, decking, roof layers, access, and complexity. |
| Re-Roofing | New roof covering over an eligible existing roof surface when conditions allow. | $7,500–$60,000+ | Existing roof condition, roof layers, material, slope, flashing, and eligibility. |
| New Roof Installation | New roofing system for a new home, ADU, addition, garage, detached structure, or commercial building. | $8,500–$125,000+ | Building type, roof design, material, slope, underlayment, ventilation, and access. |
| Commercial Roofing | Commercial flat roof repair, coating, restoration, replacement, drainage, and membrane work. | $1,200–$250,000+ | Building size, drainage, insulation, penetrations, roof access, system type, and deck condition. |
What Changes a Roof Estimate?
Two roofs with the same square footage can price differently because the total project is affected by access, slope, material, damage, roof shape, and building details.
Roof Size
Larger roof surfaces require more material, labor, underlayment, flashing, cleanup, and disposal planning.
Roof Material
Asphalt shingles, tile, metal roofing, and flat roof systems have different installation methods and planning ranges.
Roof Slope
Steeper roofs can change labor, access, staging, safety setup, and installation time.
Existing Layers
Old roof layers can affect tear-off, disposal, re-roofing eligibility, and deck inspection needs.
Decking Condition
Soft, sagging, or damaged roof decking can expand the project beyond the surface roof material.
Flashing Details
Skylights, chimneys, walls, valleys, vents, roof edges, and penetrations can change the scope.
Solar Panels
Existing or planned solar panels can affect access, timing, roof replacement planning, and roof material decisions.
Urgency
Active leaks, water entry, storm damage, and temporary protection needs can change repair planning.
Roof Cost Estimator Questions
These answers explain how to use the roof cost estimator and why final pricing depends on roof inspection and project scope.
How accurate is the roof cost estimator?
The estimator is a planning tool. It uses roof size, material, slope, project type, complexity, and visible issues to create a general range. Final pricing depends on roof inspection, access, materials, decking, flashing, permits, and scope.
Why does roof size matter so much?
Roof size affects material quantity, underlayment, labor, flashing, cleanup, disposal, and installation time. Roof surface area can be larger than the building footprint because of pitch, overhangs, garages, and roof shape.
Why are repair estimates different from replacement estimates?
Repair estimates usually focus on one or more problem areas. Replacement estimates involve a larger roof system scope, including material removal, underlayment, flashing, roof covering, ventilation, cleanup, and deck review.
Can the estimator tell me whether to repair or replace?
The estimator can help compare repair and replacement planning, but the right direction depends on roof age, leak history, material condition, decking condition, and whether damage is isolated or widespread.
