A gravel stop refers to a protective roofing component that is designed to prevent the displacement of loose materials, such as gravel or stones, from flat or low-sloping roofs. It is typically installed along the edge of a roof or parapet wall to create a barrier that holds the gravel or stones in place, preventing them from falling off or being blown away by strong winds.
The construction of a gravel stop commonly involves a strip of metal, such as aluminum or steel, which is installed horizontally at the perimeter of the roof or wall. This metal strip is usually L-shaped with one leg extending upwards onto the roof or wall surface and the other leg pointing outwards to secure the loose materials. The vertical edge of the gravel stop is often bent or turned inward to improve its grip and prevent the gravel from rolling off.
A gravel stop serves multiple purposes. Primarily, it functions as a safeguard against water infiltration by preventing the gravel from shifting and creating gaps or exposing vulnerable areas of the roofing system. Additionally, it helps maintain the overall integrity and aesthetic appeal of the roof by keeping the gravel in its intended location. Moreover, a gravel stop can aid in directing water towards the proper drainage system and reducing the risk of clogged gutters or downspouts caused by loose materials.
In conclusion, a gravel stop is a protective metal strip used along the edges of roofs or parapet walls to hold loose materials, such as gravel or stones, in place and prevent them from dislodging or blowing away.
