Construction
Roof Area Calculator
Calculate the true sloped surface area of a roof from its footprint dimensions and pitch angle. The slope multiplier (1/cos(pitch)) corrects for the fact that a pitched roof has more material area than the horizontal footprint it covers.

Construction
Brick Quantity Calculator
Estimate how many bricks you need to cover a wall, dividing total wall area by the face area of one brick. Useful for ordering materials and getting a cost estimate before starting a masonry job.
