What is a Gravel Stop?
Gravel stops are metal flashings installed at the edges of a gravel roof. They serve multiple purposes, including protecting the roof membrane from water infiltration, providing a clean termination point for the roofing material, and enhancing the overall aesthetic of the building. These systems are particularly important for built-up roofs (BUR), where gravel is used as a protective layer. They are available in various materials, including aluminum and galvanized steel, to meet specific building requirements.
Benefits of Using Gravel Stops
-
Water Management
Gravel stops help direct water away from the roof edge, preventing pooling and potential damage to the underlying structure. This is particularly vital in areas with heavy rainfall or snow accumulation. -
Wind Uplift Resistance
Properly installed gravel stops enhance the roof’s ability to withstand high winds, reducing the risk of damage during storms. This is crucial for maintaining the integrity of commercial roofing systems. -
Aesthetic Appeal
Available in various colors and finishes, gravel stops can complement the building’s architecture. They provide a polished look, enhancing the overall curb appeal.
-
Maintenance Simplification
Gravel roofs can be challenging to maintain, but gravel stops simplify the process by providing a defined edge. This facilitates easier inspections and repairs. -
Customization Options
Many manufacturers, including those like www.metalera.com and www.hickmanedgesystems.com, offer customizable gravel stop solutions to suit specific project needs, ensuring a perfect fit for any roofing system.
Types of Gravel Stops
Standard Gravel Stops
Standard gravel stops are commonly used in low-slope commercial roofing applications. Made from durable materials such as aluminum and galvanized steel, they provide excellent water and wind resistance. These stops typically feature a simple design that is effective for most general applications.
Press-LOC Gravel Stops
Press-LOC gravel stops, such as those available from www.saf.com, are designed for modern roofing systems, including EPDM and TPO. They feature advanced technologies that ensure a watertight seal, making them ideal for low-slope roofs that require enhanced performance.
Roofer’s Edge Gravel Stops
Roofer’s Edge gravel stops, primarily used with single-ply roofing systems, offer adjustable face heights for maximum flexibility. These stops are ANSI/SPRI tested, ensuring reliable performance for various roofing applications, as highlighted on www.hickmanedgesystems.com.
Economical Edge Systems
For contractors looking for cost-effective solutions, economical edge systems provide a great alternative. These systems allow for quick installation while maintaining quality and durability, making them suitable for general commercial roofing projects.
Custom Gravel Stops
Custom gravel stops cater to specialized applications and unique project requirements. They can be tailored in terms of size, material, and finish, ensuring that each project receives a solution that fits perfectly.
Installation Methods
-
Preparation
Start by ensuring the roof edge is clean and free of debris. Measure the area where the gravel stop will be installed to determine the appropriate length. -
Cutting and Fitting
Cut the gravel stop to the necessary length. It should fit snugly against the edge of the roofing membrane. Use appropriate tools to ensure clean cuts. -
Fastening
Secure the gravel stop in place using screws or roofing adhesive, depending on the manufacturer’s recommendations. Ensure that the fastening method chosen provides a robust connection to prevent movement. -
Sealing
Apply a sealant around the edges of the gravel stop to create a watertight barrier. This step is crucial for preventing leaks and ensuring long-term performance. -
Final Inspection
After installation, conduct a thorough inspection to ensure that the gravel stop is properly aligned and securely fastened.
