Metal roofing systems are designed to perform differently than traditional shingle roofs, especially when it comes to water shedding and thermal movement. Standing seam systems, in particular, use raised seams and concealed fasteners to reduce the risk of leaks and fastener failure over time. In Florida, where heavy rain and intense sun exposure are constant, this design helps maintain long-term performance by limiting points of entry for water and reducing expansion-related stress. Underlayment also plays a critical role in protecting the structure beneath the panels. A peel and stick membrane like TITANIUM PSU30 provides a secondary water barrier, sealing around fasteners and penetrations. Combined with proper ventilation components such as gooseneck vents and pipe boots, the system allows for controlled airflow while preventing moisture intrusion. These elements work together to ensure that both the exterior and underlying layers remain protected. For this project, a 26-gauge 1" snap lock standing seam system in mill finish was installed to provide durability and a clean, low-maintenance surface. The system includes one #3 pipe boot and four 10-inch gooseneck vents to support ventilation and functionality. Eleven rolls of TITANIUM PSU30 peel and stick underlayment were used to reinforce waterproofing, creating a complete system built for long-term performance in a high-exposure environment. https://maps.app.goo.gl/QHhf84HaJVJcpeiy7
