Roofing Calculator

Roofing Calculator helps you calculate roof area considering pitch/slope, roofing sheet quantity, and material requirements for sloped roofs, flat roofs, and gable roofs. Accurate roofing estimation for tin sheets, tiles, or asbestos roofing.

Roof area is more than floor area due to pitch (slope). Our calculator considers roof pitch to give you accurate roof area and material quantity, preventing shortages during roofing work.

**Key Features:**
- Calculate actual roof area with pitch
- Support for flat, gable, and hip roofs
- Roof pitch angle consideration
- Roofing sheet quantity calculation
- Support for different sheet sizes
- Overlap and wastage included
- Ridge and eave calculations
- Support for feet and meters
- Instant accurate calculations
- Works offline - perfect for construction sites
- Share roofing estimate with contractor
- Clean interface for field use
- No registration or login needed
- Remove ads with one-time purchase

**Perfect For:**
- Home roofing work planning
- Warehouse and shed roofing
- Contractor material estimation
- Cost calculation for roofing
- Tin sheet roofing quantity
- Tile roofing estimation
- Roofing renovation work
- Waterproofing area calculation

**Common Roof Pitches:**
- Flat roof: 0-5° pitch (minimal slope)
- Low pitch: 10-20° pitch
- Medium pitch: 20-35° pitch (common for residential)
- High pitch: 35-45° pitch (shed water quickly)

**Roofing Sheet Sizes:**
- GI sheets: 8 ft, 10 ft, 12 ft lengths
- Width: typically 3 ft (covers 2.5 ft after overlap)
- Asbestos sheets: 6 ft × 3 ft, 8 ft × 4 ft

**Example:**
Building: 30 ft × 40 ft
Roof pitch: 30° (gable roof)
Actual roof area: ~1,400 sq.ft (vs 1,200 sq.ft floor)
10 ft GI sheets (3 ft wide): ~65 sheets

Higher pitch sheds rain/snow better but needs more material. Minimum pitch 10° for proper water drainage.
