Firrings Timber | Tapered Roof Firrings for Flat Roof Construction
(0 products)Browse our range of firrings timber — merchant-quality tapered firring pieces designed to create the correct fall on flat roof constructions. Essential for directing water away from flat and low-pitched roofs, firrings are a critical component in any compliant flat roof build. Nicks Timber supplies roofing firrings to the sizes and falls specified by builders and roofing contractors, backed by the expertise of a timber merchant established since 1856.
Firrings — sometimes called firring pieces or firring strips — are tapered lengths of timber used to create a controlled fall across a flat roof deck. Rather than laying a flat substrate and relying on the roofing membrane alone to shed water, firrings introduce a precise, consistent gradient that channels rainwater efficiently towards outlets and guttering, reducing the risk of ponding and prolonging the life of the roof covering.
Correctly specified firrings are a Building Regulations requirement on flat roof constructions in the UK, with a minimum fall of 1:80 recommended — though 1:40 is widely regarded as best practice. Available in a range of fall ratios and lengths, our firrings can be cut to suit the specific requirements of your roof design.
Firrings are typically fixed to the top of flat roof joists before the decking board or insulation layer is applied, making them an early-stage but essential component of any flat roof build — whether on a new extension, outbuilding, porch, or commercial structure.
At Nicks Timber, we've been supplying specialist roofing timber to the trade since 1856. That depth of experience means we stock the profiles and falls that roofing contractors and builders actually need, with the consistent quality and reliable availability that trade customers depend on.
