Head Lap, Side Lap, and Pitch

If you have a slate roof, you may have heard the terms "head lap" and "side lap" before. These are important factors that affect the performance and longevity of your slate roof, and it's essential to get them right.

Head lap refers to the overlap of the slates on the roof. It's the distance that one slate extends over the one below it. Proper head lap is essential to ensure that water flows off the roof properly and doesn't leak into the building. If the head lap is too small, water can seep through the gaps between the slates and cause leaks or damage.

Side lap refers to the overlap of the slates on the sides of the roof. It's the distance that one slate extends over the one next to it. Proper side lap is essential to ensure that the slates are secure and don't shift or slide out of place. If the side lap is too small, the slates may become loose and fall off the roof.

Proper head lap and side lap are essential for the performance and longevity of your slate roof. It's important to follow the manufacturer's recommendations for these measurements, as well as local building codes. If you're unsure about the head lap and side lap for your slate roof, it's a good idea to contact a professional slate roof repair company for guidance.

In conclusion, proper head lap and side lap are crucial for the performance and longevity of your slate roof. Make sure to follow the manufacturer's recommendations and local building codes to ensure that your roof is secure and watertight. If you have any questions or need assistance with your slate roof, don't hesitate to contact a professional slate roof repair company.
