Roof Leak Repair Cost Estimator

Estimate your roof leak repair cost based on damage size, roof material, repair complexity, and local labor rates.

Damaged/Affected Area (sq ft)

Roof Material

Asphalt Shingles Wood Shingles / Shake Metal Roofing Tile (Clay or Concrete) Slate Flat / EPDM / TPO

Repair Complexity

Simple (minor patch, single leak point) Moderate (flashing repair, small section replacement) Complex (structural damage, multiple leak points)

Local Labor Rate ($/hr)

Estimated Labor Hours

Contractor Overhead & Profit Markup (%)

Emergency / After-Hours Service?

No Yes (+35% surcharge)

Calculate Repair Cost

function rooCalc() { var resultDiv = document.getElementById('roo-result'); resultDiv.style.display = 'none'; resultDiv.innerHTML = '';

// --- Inputs --- var area = parseFloat(document.getElementById('roo-damage-area').value); var matCostSqFt = parseFloat(document.getElementById('roo-roof-type').value); var complexity = parseFloat(document.getElementById('roo-complexity').value); var laborRate = parseFloat(document.getElementById('roo-labor-rate').value); var laborHours = parseFloat(document.getElementById('roo-labor-hours').value); var markupPct = parseFloat(document.getElementById('roo-markup').value); var emergency = parseFloat(document.getElementById('roo-emergency').value);

// --- Validation --- var errors = []; if (isNaN(area) || area 100) errors.push("Markup must be between 0% and 100%.");

if (errors.length > 0) { resultDiv.style.display = 'block'; resultDiv.innerHTML = ''; return; }

// --- Formula --- // Material Cost = Area (sq ft) × Material Cost per sq ft × Complexity Multiplier var materialCost = area * matCostSqFt * complexity;

// Labor Cost = Labor Hours × Labor Rate per Hour × Complexity Multiplier var laborCost = laborHours * laborRate * complexity;

// Subtotal before markup var subtotal = materialCost + laborCost;

// Apply emergency surcharge var afterEmergency = subtotal * emergency;

// Apply overhead & profit markup var markupAmount = afterEmergency * (markupPct / 100); var totalCost = afterEmergency + markupAmount;

// Low / High range (±15%) var lowEstimate = totalCost * 0.85; var highEstimate = totalCost * 1.15;

#### Formula

Material Cost = Damaged Area (sq ft) × Material Cost per sq ft × Complexity Multiplier Labor Cost = Labor Hours × Labor Rate ($/hr) × Complexity Multiplier Subtotal = Material Cost + Labor Cost After Emergency = Subtotal × Emergency Surcharge Factor Total Cost = After Emergency × (1 + Markup % / 100) Estimate Range = Total Cost × 0.85 to Total Cost × 1.15
