Buy Treated Roof Firrings

Our range of roof firrings offers a practical and reliable solution for creating gradients on flat roofing systems. Designed to help direct rainwater towards the lower edge of the roof, flat roof firrings play an essential role in ensuring effective drainage and protecting the structure from water pooling.

Made from treated timber, each timber roof firring has undergone a drying, treatment, and re-drying process to improve resistance against moisture and rot. This makes them suitable for long-term use in exposed roof environments.

Available in a variety of sizes, each firring is priced per individual length, allowing you to order exactly what you need for your project. In addition to improving water run-off, firrings can be used to reinforce a flat roof structure. When paired with I-joists or open web joists, they help provide a solid base for insulation and roof coverings, while also enhancing the overall strength of the roof frame.

At Mitcham Builders Merchants, we keep a wide selection of flat roof firrings in stock and ready for collection or delivery. You can shop online for quick turnaround - same or next day delivery is available depending on your location - or visit us in-store at our Croydon branch to speak to our knowledgeable team in person.

Whether you're building a new flat roof or upgrading an existing one, our timber roof firring options, along with all your other roofing materials, are available under one roof at South London's largest independent builders merchant.
