📐 Essential for Flat Roof Drainage

Firring strips are tapered timber lengths, thicker at one end and thinner at the other. When fixed to roof joists, they create a slope (fall) which allows water to run off into gutters or drainage outlets.

Without firrings, flat roofs can suffer from:

Water pooling
Premature wear
Increased risk of leaks

👉 Using firrings ensures your roof performs properly and lasts longer.
