The builders’ kerb, is a vital part of any rooflight installation. However, crafting one from scratch, to the exact size and correct pitch, can be tricky.

Save yourself the time and trouble of constructing your own kerb, by having our expert engineers do it for you. Roof Maker’s builders’ kerbs are precision engineered specifically for the rooflight you are installing, so you can be sure of a perfect fit every time.

Pitch perfect to drain away rainwater

We recommend installing our flat rooflight at a pitch of five degrees. This angle allows rainwater to slide off the surface of the glass, avoiding unsightly residues left when water is allowed to evaporate. For your convenience, if purchased along with a flat rooflight, our builders’ kerb has this five-degree pitch already incorporated into the design. The kerb supplied with our Slimline and Pyramid roof lanterns are supplied flat.

 

Even better thermal insulation

Your kerb will have a quality plywood or OSB exterior with an insulating core. This composition provides exceptional thermal performance, with a Ug-value of just 0.3 W/m²K.

Practical and affordable

Investing in a precision-made, prefabricated builders’ kerb is both sensible and economical. Prices start at £250 + VAT.

 

Simple Bracket Installation

Purchasing our pre-built builder’s kerb makes installation incredibly easy. You simply fasten the builders’ kerb to your roof, using brackets, then secure the rooflight on top as per our fitting instructions.
