What is the consequence of not following the recommended head lap for slate roofing?

• A. It may improve drainage
• B. It may lead to leaks
• C. It decreases the weight of the roof
• D. It increases the installation time

Answer: (B)

Not adhering to the recommended head lap for slate roofing can significantly compromise the roof's waterproofing effectiveness. The head lap is crucial in allowing water to shed efficiently down the roof's slope. If the head lap is insufficient, water can pool behind the slates, leading to capillary action that pulls water into the structure, ultimately causing leaks. In addition to the immediate concern of water infiltration, this improper installation may also contribute to the deterioration of the roofing materials over time, as standing water and moisture can lead to mold growth and damage to underlying structures. Therefore, following industry-standard head lap guidelines is essential for sustaining the integrity and longevity of a slate roof and ensuring that it performs its primary function of protecting the building from water intrusion.
