An EPF felt tray, also known as an eaves protection felt tray, is a simple but critical component in a modern roofing system. Installed along the eaves — the lower edge of a sloping roof — the tray supports the underlay and channels water safely into the guttering system. Without a felt support tray in place, the roofing underlay can sag between the rafters, leading to pooling, water ingress, and eventual damage to roof timbers and ceilings. Whether you're replacing an old roof or upgrading your roofline, installing EPF felt trays is essential for long-term weatherproofing and performance.
Traditionally, roofing underlay would run directly over the rafters and into the gutter. However, over time this underlay becomes brittle and degrades under constant exposure to UV light, frost, and water. When the underlay begins to sag or tear near the eaves, it can lead to serious issues such as:
An EPF felt tray solves these issues by providing a rigid surface that supports the underlay and ensures rainwater is directed straight into the guttering — even as the felt ages. The tray sits beneath the bottom course of roof tiles and above the fascia board, creating a smooth run-off for moisture. Modern trays are made from durable polypropylene or PVC, resistant to decay, frost damage, and UV rays. Once fitted, they provide reliable protection for the vulnerable eaves section of your roof for decades to come.
We install EPF felt trays as part of our full re-roofing service, roofline upgrades, and whenever we replace soffits and fascias. It's a straightforward but essential improvement that forms part of our standard best-practice installation. If you're experiencing damp issues or if your existing underlay is visibly sagging into the gutter, we highly recommend adding felt trays during any roofline or tile repair work.
EPF felt trays are especially important when installing new uPVC fascia and soffit systems. Without proper support at the eaves, the underlay may allow water to bypass the gutter entirely, causing premature decay in timber and brickwork. With a tray in place, this risk is eliminated, providing a watertight seal that protects both the exterior and interior of your home. The system also helps keep birds, insects, and debris from nesting under the tiles, preserving airflow and roof integrity.
All our installations use BBA-approved felt support trays from trusted suppliers. These are compatible with most tile profiles and roof pitches and can be retrofitted to many existing rooflines with minimal disruption. During installation, we also inspect your existing underlay, rafter ends, and fascia condition to ensure the entire area is sound and properly ventilated.
