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 and Headlap

Headlap:

• 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.
