katusekattekihist

Katusekattekihist refers to the underlayment layer beneath the primary roofing material. Its primary function is to provide an extra layer of protection against water infiltration. In the event that the main roofing material, such as shingles or tiles, is damaged or compromised, the katusekattekihist acts as a secondary barrier, preventing water from reaching the roof deck and the interior of the building.

This layer is typically made from materials like asphalt-saturated felt or synthetic membranes. The specific type of katusekattekihist used can vary depending on the climate, the type of roofing material, and building codes. In colder regions, it often plays a role in preventing ice dams from causing water to back up under the roofing material.

Proper installation of the katusekattekihist is crucial for its effectiveness. It is usually laid directly on the roof deck before the primary roofing is applied, often overlapping seams to ensure a continuous waterproof surface. While not always visible once the roof is completed, the katusekattekihist is an essential component of a durable and weather-resistant roofing system, contributing significantly to the longevity and structural integrity of a building.
