Product Details
Bitumen Roof Felt is a waterproof roofing material that comes in a 10-metre roll, typically used to protect garden sheds, garages, and other outbuildings from water damage. The felt features a mineral-coated surface in green slate finish that provides UV protection while blending naturally with garden surroundings. It's installed by rolling out across the roof deck, overlapping sheets by at least 7.5cm, and securing with clout nails at specified intervals along the edges and seams. This durable material creates a watertight barrier when properly installed, with most products offering around 5 years of protection for your outdoor structures.

Frequently Asked Questions
What area does a 10m roll of bitumen roof felt cover?
A 10m roll of bitumen roof felt typically covers approximately 10 square metres, as most rolls are 1 metre wide. However, you'll need to account for overlaps of at least 7.5cm between sheets, which reduces the effective coverage area.
What tools do I need to install bitumen roof felt?
You'll need clout nails (galvanised 13mm), a hammer, measuring tape, stanley knife for cutting, and chalk line for marking. A nail gun can speed up installation for larger projects.
Is bitumen roof felt suitable for flat roofs on houses?
Bitumen roof felt in 10m rolls is primarily designed for outbuildings like sheds and garages. For main house flat roofs, you'll typically need heavier-duty roofing systems with proper torch-on membranes or EPDM rubber.
How long does bitumen roof felt last on outdoor buildings?
Quality bitumen roof felt typically lasts 5-8 years on sheds and outbuildings when properly installed. Lifespan depends on weather exposure, roof pitch, and maintenance, with steeper pitches generally lasting longer.
Can I install bitumen roof felt in winter?
Yes, but avoid installation during freezing conditions as the felt becomes brittle and difficult to handle. Ideal installation temperature is above 5°C, and avoid wet or windy conditions for best results.
