What type of cement is commonly used to secure layers of asphalt shingles together?

Roofing cement is a specific type of cement that is particularly formulated for use in roofing applications, including the installation and securing of asphalt shingles. It is designed to withstand the weather and to maintain a strong bond in various conditions, which is essential for the longevity and performance of roofing materials.

This product remains pliable, allowing it to accommodate the natural expansion and contraction of roofing materials caused by temperature changes without cracking or losing its adhesive properties. Its use extends beyond just securing shingles; it can also be employed in repairing leaks and sealing joints or flashing, further contributing to a roof's integrity.

On the other hand, construction cement, quick-dry cement, and Portland cement serve different purposes and are not specifically tailored for roofing applications. Construction cement is generally used for a wide range of building needs, quick-dry cement is designed for fast setting in various construction applications, and Portland cement is a key ingredient in many types of concrete but is too rigid and not suited for roofing needs where flexibility and moisture resistance are beneficial.
