# Slate Roof Tiles

The Slate Roof Tiles Calculator is a practical tool designed to help homeowners, contractors, and roofing professionals accurately estimate the number of slate tiles needed for a roofing project. You can determine the total number of tiles required, including waste, by inputting key parameters to complete your roofing project efficiently.

 Tile Exposure: Length in Tile Exposure: Area in² Tile Exposure: Area ft² Number of Tiles per Square # Tiles Needed tiles Waste Percentage Adds # of tiles Total # of Tiles Needed tiles

#### Calculation

1. enter the area of the roof that needs to be covered with tiles in square feet
2. the overlap length of the tile to ensure proper coverage and water resistance
3. the length of a single tile in inches
4. the width of a tile in inches
5. enter the percentage of additional tiles required to account for cutting and breakage

#### Results

1. the effective exposed length of each tile in inches
2. the exposed area of each tile in square inches
3. the exposed area of a tile in square feet
4. the number of tiles needed per square (100sq ft)
5. the number of tiles required to cover the roof area
6. the additional number of tiles necessary to account for waste
7. the total number of tiles needed, including waste

• The part of the tile that is overlapped by the two rows of tiles above it.
• It ensures that water runs off correctly and doesn't seep between tiles, vital for preventing leaks.
##### Tile Exposure:
• This is the portion of the tile that remains visible after installation.
• It determines how much of the roof is covered by each tile.

### Formula for Tile Exposure Length

`Tile Exposure Length = (Tile Length-Head Lap) / 2`
##### Explanation
• Tile Length: The length of a single tile.
• Head Lap: The part of the tile covered by two tiles above it. The formula accounts for the overlap, dividing the remaining length by 2 to determine the effective exposure of each tile.

### Example Calculation

• A tile length of 12 inches
• A head lap of 3 inches
The tile exposure length would be:
`Tile Exposure Length = 12 - 3 = 9 / 2 = 4.5 inches`
This calculator is essential for planning and budgeting roofing projects, ensuring accurate materials estimates and minimizing waste.
