Frequently Asked Questions
Ridge caps are specially profiled metal components that cover the apex (peak) where two roof planes meet. They’re essential for sealing the ridge line against water ingress, providing a finished appearance, and in some cases, enabling roof ventilation. Without proper ridge capping, your roof is vulnerable to leaks, pest entry, and weather damage. Ridge caps also give your roof a professional, complete look while ensuring long-term weather protection.
The correct ridge cap depends on your roof profile, pitch, and ventilation needs. When ordering, let our team know your roof pitch and the roofing profile you’re using (e.g., Corodek® , Trimclad®). We’ll recommend the appropriate ridge cap style and ensure proper fitment for your project.
Absolutely. Our Standard Ridge Cap is available with mesh to provide natural ventilation – ideal for industrial and light industrial buildings.
