75° Mono Ridge Flashing Backer Plate for Standing Seam - 3m
Complete the upper edge of your mono‑pitch standing seam roof with this 3m long 75° mono ridge backer plate.

About Our 75° Mono Ridge Backer Plate for Standing Seam
Our mono ridge backer plates give your standing seam roof the stable support required for a neat, long‑lasting ridge detail. This 75° profile is made to sit directly beneath the mono ridge flashing, helping form a clean junction at the highest point of a single‑pitch roof.
Manufactured from hard‑wearing, eco‑friendly GreenCoat® Pural BT coated steel, the backer plate offers strong scratch resistance, reliable weather protection and excellent long‑term durability. It’s designed for use specifically with Cladco standing seam sheets, where the concealed‑fix system delivers a smooth, uninterrupted finish.
Backer plates are installed in combination with mono ridge flashings and Z‑bars to create a sealed and protected ridge line. Components can be purchased individually or as part of a flashing kit to streamline installation and ensure a perfect fit across the roof.

Fixing Guidance
Mono ridge backer plates are installed in partnership with mono ridge flashings and Z‑bars to create a secure, fixing‑free ridge detail on standing seam roofs. Where additional reinforcement is required in exposed or coastal conditions, installers may choose to add colour‑matched 6.3x20mm stainless or Ruspert® screws. While the screws won’t be concealed, choosing colour‑matched options ensures they blend against the sheet colour.
For recommended tools, aftercare tips and full installation steps, please refer to the standing seam installation guide on our Help & Advice page.

Customer Collection Notice
Please ensure you have pre-booked your collection slot before travelling to site.
When arriving to collect your order, please report to a member of our Warehouse Team who will register your arrival and locate your goods. Once ready, your items will be picked and brought to your vehicle loading area.
During busy periods, there may be a short wait while our yard team assist other customers or complete other loading tasks. We always do our best to work within your booked collection time.
We respectfully draw your attention to the following important points:
- Loading is ultimately the customer’s responsibility. While our team can assist with mechanical loading using forklifts, we cannot handball items into enclosed vehicles. Customers must ensure their vehicle is suitable and that goods are safely loaded and adequately secured before leaving the premises.
- Sharp sheeting, metal goods, and long/heavy items may pose additional handling risks. Please come prepared with high-quality protective gloves, and any appropriate protection materials to avoid damage to your vehicle or restraints (e.g. ropes or straps). The edges of roofing sheets and metal products can be extremely sharp, and care should be taken when handling.
- We strongly recommend that customers bring their own straps, ropes, or other securing materials, as we are unable to provide these at the point of collection.
- If you are unsure of your vehicle’s load capacity, we can advise the approximate weight of your order in advance. It is your responsibility to ensure your vehicle is suitable for transporting the goods safely and legally.
- Cladco will not be held liable for any damage to your vehicle or goods once they have been loaded and leave our premises. Loading assistance is provided entirely at the customer’s own risk.
Click & Collect – Pre-Booking Required
You are welcome to collect your order from either our Okehampton (Devon) or Andover (Hampshire) site. All collections must be pre-booked in advance so your items can be picked, packed and ready for you.
Please do not travel to site without a confirmed collection time, as we cannot guarantee your order will be available.
Once your items are ready, you will receive an email with a link to book your collection slot. Please note, same-day collections are not available and bookings must be made at least two hours in advance.
When you arrive, please bring your order confirmation and follow the signage to the collection area where a member of our team will assist you.
