SCREW-DOWN METAL ROOFING SYSTEM
SCREW-DOWN METAL ROOFING SYSTEM
The screw-down metal roofing system is a type of metal roof made up of panels that are fastened directly to the roof structure using exposed screws. At A&J Construction LLC, we install this system in Penobscot, Waldo, Knox, Kennebec, Somerset, Androscoggin, and Cumberland counties in Maine, adapting each installation to the specific conditions of the property.
This system is used on roofs where a functional metal solution is required, with a direct installation method that secures the panels to the structural base. The screws go through the panel and fasten it to the surface, providing a firm hold throughout the entire system.
How does this system work?
Unlike other concealed metal systems, in a screw-down system the fastening points remain exposed and are distributed across the panels. This allows each section to be secured directly to the structure, keeping the panels in place under various weather conditions.
The system works in combination with:
- Metal panels that cover the roof surface
- Screws with sealing washers that help prevent leaks
- Panel overlaps designed to direct water flow
- Sealing components at joints and edges
System considerations
Due to its design, this type of roofing requires careful attention to several factors to ensure proper performance. Screws must be installed correctly to prevent leaks, while the seals at fastening points should be inspected periodically over time. Additionally, the natural expansion and contraction of the metal can affect the system’s tightness, making proper panel alignment essential for effective drainage.
Installation process
The service is carried out in an organized manner to ensure that each component functions correctly:
- Roof structure evaluation
- Preparation of the base surface
- Installation of metal panels with proper overlap
- Fastening with screws at strategic points
- Sealing at joints, edges, and penetrations
- Final inspection of the installed system
System application
Screw-down metal roofing is used on properties where a practical metal system is needed and can adapt to different roof configurations. Its performance depends largely on proper installation, especially at fastening and sealing points.
At A&J Construction LLC, this service is performed with careful consideration of each property’s conditions, ensuring the system is properly installed and integrated with the rest of the structure. We also offer free inspections and estimates to evaluate each project.
