Roof Cleaning Cost Estimator

Estimate your roof cleaning cost based on roof size, pitch, material type, and cleaning method. Prices reflect typical U.S. contractor rates.

Roof Area (sq ft)

Roof Pitch

Low (0/12 – 3/12) — flat to slight slope Moderate (4/12 – 6/12) — standard Steep (7/12 – 9/12) Very Steep (10/12+)

Roof Material

Asphalt Shingles Metal Roof Tile (Clay / Concrete) Wood Shake / Cedar Slate

Cleaning Method

Soft Wash (low pressure + chemical) Pressure Wash (high pressure) Chemical Treatment only

Number of Stories

1 Story 2 Stories 3+ Stories

Roof Condition / Debris Level

Light (minor algae / dust) Moderate (moss, lichen patches) Heavy (thick moss, heavy staining)

Include Gutter Cleaning?

No Yes

Gutter Linear Footage (if yes)

Calculate

function rooCalc() { var resultDiv = document.getElementById('roo-result');

// --- Inputs --- var area = parseFloat(document.getElementById('roo-area').value); var pitch = parseFloat(document.getElementById('roo-pitch').value); var baseRate = parseFloat(document.getElementById('roo-material').value); var method = parseFloat(document.getElementById('roo-method').value); var stories = parseFloat(document.getElementById('roo-stories').value); var condition = parseFloat(document.getElementById('roo-condition').value); var gutters = parseInt(document.getElementById('roo-gutters').value); var gutterLen = parseFloat(document.getElementById('roo-gutter-length').value) || 0;

// --- Validation --- if (isNaN(area) || area 20000) { resultDiv.innerHTML = '⚠ Please enter a valid roof area between 100 and 20,000 sq ft.'; resultDiv.style.display = 'block'; return; } if (gutters === 1 && (isNaN(gutterLen) || gutterLen 1000)) { resultDiv.innerHTML = '⚠ Please enter a valid gutter length between 0 and 1,000 linear ft.'; resultDiv.style.display = 'block'; return; }

// --- Core Formula --- // Base cost = Area × Base Rate ($/sq ft by material) // Adjusted cost = Base cost × Pitch Factor × Method Factor × Stories Factor × Condition Factor // Gutter cost = Gutter linear ft × $1.50/lf (standard gutter cleaning rate) // Minimum job charge = $150

var GUTTER_RATE = 1.50; // $/linear ft var MIN_CHARGE = 150.00; // minimum job cost

var roofCost = area * baseRate * pitch * method * stories * condition;

// Apply minimum charge
if (roofCost ' +
'Roof Cleaning Cost' +
'$' + roofCost.toFixed(2) + '' +
(gutters === 1
? 'Gutter Cleaning (' + gutterLen + ' lf × $1.50)' +
'$' + gutterCost.toFixed(2) + '': '') + '' + 'Total Estimated Cost' + '$' + totalCost.toFixed(2) + '' + 'Typical Range' + '$' + low.toFixed(0) + ' – $' + high.toFixed(0) + '' + 'Effective Rate (roof only)' + '$' + effectiveCPSF.toFixed(3) + ' / sq ft' + ''; resultDiv.style.display = 'block'; }

#### Formula

Roof Cleaning Cost = Roof Area (sq ft) × Base Rate ($/sq ft) × Pitch Factor × Method Factor × Stories Factor × Condition Factor

Gutter Cleaning Cost = Gutter Linear Footage × $1.50 / lf

Total Cost = Roof Cleaning Cost + Gutter Cleaning Cost (minimum $150)

Base Rates by Material: Asphalt $0.10, Metal $0.13, Tile $0.16, Wood Shake $0.18, Slate $0.20 per sq ft

Pitch Factors: Low 1.00 ×, Moderate 1.10 ×, Steep 1.25 ×, Very Steep 1.45 ×

Method Factors: Soft Wash 1.00 ×, Chemical Only 1.15 ×, Pressure Wash 1.30 ×

Stories Factors: 1-story 1.00 ×, 2-story 1.15 ×, 3+-story 1.30 ×

Condition Factors: Light 1.00 ×, Moderate 1.15 ×, Heavy 1.35 ×

The estimated range is ±15% of the calculated total to reflect regional labor variation.
