📌 Important Note: The Tuff-Rib Roof Ridge Cap must be used in conjunction with the matching Tuff-Rib PVC roofing panels (High Wave) to ensure a complete and watertight roofing system. Proper overlapping and fastening during installation is critical for optimal performance.
🔧 Installation Overview
1
Ensure the Tuff-Rib PVC roofing panels on both slopes are fully installed and fastened before fitting the ridge cap.
2
Position the ridge cap centrally over the apex of the roof, aligning its high-wave profile with the roofing panels below.
3
Overlap adjacent ridge cap sections by a minimum of 150mm to prevent gaps and ensure continuous waterproofing.
4
Fasten the ridge cap using appropriate roofing screws with neoprene washers at each corrugation point.
5
Inspect all joints and fastening points after installation to confirm a secure, weather-tight finish.

❓ Frequently Asked Questions
Q What is the difference between the High Wave and Low Wave Tuff-Rib Ridge Cap?
The High Wave ridge cap is specifically designed to match the taller corrugation profile of High Wave Tuff-Rib roofing panels. It provides a deeper coverage over the ridgeline and must be used with the corresponding High Wave roofing panels for a proper watertight fit. Using mismatched profiles will result in gaps and potential leaks.
Q What material is the Tuff-Rib Roof Ridge Cap made from?
The ridge cap is manufactured from a composite of ASA (Acrylonitrile Styrene Acrylate) and PVC synthetic resin. The ASA outer layer provides superior UV resistance and color retention, while the PVC core delivers structural strength and durability.
Q How long does the ASA PVC Roof Ridge Cap last?
Under normal weather conditions, ASA PVC synthetic resin roofing accessories are designed to last 25–30 years or more. The ASA surface layer resists UV degradation, thermal deformation, and color fading, ensuring long-term performance even in harsh climates.
Q Is the ridge cap available in different colors?
Yes, the Tuff-Rib Roof Ridge Cap is available in a range of standard colors to match the corresponding Tuff-Rib roofing panels. Please contact the supplier for available color options and custom color requests.
Q What fasteners should be used to install the ridge cap?
It is recommended to use self-tapping roofing screws with neoprene (rubber) washers. The neoprene washer creates a weatherproof seal around the screw hole, preventing water from penetrating at fastening points. Screws should be driven at each corrugation peak to ensure secure attachment.
Q Can this ridge cap be used on roofs with steep pitches?
Yes, the Tuff-Rib Roof Ridge Cap is suitable for a wide range of roof pitches commonly used in residential and commercial construction. For very steep pitches or specific structural requirements, please consult a professional installer or contact the manufacturer for guidance on the appropriate installation method.
