About this deal

But roof vents aren’t as simple as just drilling some holes in your roof and calling it a day. To make sure that the roof is still waterproof, you need to use specially designed roof vents. But there’s no reason to fear, there are several different approaches to roof vents and you’re sure to find one that suits your roof. Tiled Vents Products are also available for slate roofs in the form of slate vents. Compact, easy to install, and discreet, these vents are ideal for period properties and stone houses, where they promote airflow and keep roof spaces free from condensation. They slot in place just like regular roof slates and blend in seamlessly with the rest of the roof. All damaged or missing items should be reported to the driver and signed for as damaged or missing, wherever possible.

Felt lap vents are another great way to help ventilate your loft or attic. Rather than creating an opening in the roof itself, felt lap vents just create an opening in the roofing felt. Roofing felt is a membrane between the tiles and the actual loft. While the tiles on the top of a house allow some air through, felt lap vents allow that air to make it through the roofing felt. This is particularly important if your house has roofing felt made up of a non-breathable membrane. At ERoofing, we carry the versatile and effective Manthorpe Felt Lap Vent, one of our best-selling products. The key with abutment vents is that there needs to be a gap between the nearest batten and the flat wall. – 10mm for the Manthorpe vent though this can vary. The roofing felt needs to be draped around the battens so that the 10mm gap is clear. After this, the top layer of tiles needs to be placed so the abutment vent can be installed. The product has been designed as a remedial solution to help overcome the build-up of condensation in the roof space, however like all products that open the felt lap to provide ventilation it does not meet the code of practice BS 5534:2014+A2:2018 6.2.1.1. The specifier or user should be aware that the opening of felt laps on the roof may adversely affect the driving rain resistance of the slates, tiles or shingles, as well as increase the wind uplift forces acting on them. Felt lap vents are designed to increase the amount of ventilation in existing roof spaces. They tend to be fitted retrospectively to properties which have additional loft insulation, with the roof lap vent helping to combat the issue of condensation accumulation. Loft vents come in all shapes and sizes. Our top 5 Loft Ventilation Products to stop condensation in your attic are listed below: Felt Lap VentsPlease Note: The specifier or user should be aware that the opening of felt laps on the roof may adversely affect the driving rain resistance of the slates, tiles or shingles, as well as increase the wind uplift forces acting on them. Made from an injected moulded polypropylene they are a lightweight solution that is fully recyclable. How Many Vents Do I Need? The Manthorpe Felt Lap Vent is a refurbishment product designed to increase the amount of ventilation into existing roof spaces. Easy to fit and install with a tapered lead-in that aids in smoothly slotting between the felt laps, these felt lap vents from Manthorpe are refurbishment products that increase ventilation in your existing roof spaces. For roof spaces that require more than the 15000mm/m² the spacings half for each additional 5000mm/m²

A felt lap vent will not meet the requirements for roof space ventilation on its own. The felt lap vent only provides airflow through the vent flaps and will need to be paired with another kind of roofing ventilation to ensure your roof space is fully ventilated. Roof ventilation has always been critical in letting a house or building ’breathe’ and ensure that roof spaces don’t gather moisture and condensation with unpleasant and possibly costly consequences. However, in modern houses with more efficient central heating systems and highly effective insulation methods, temperature differences created between living and roof spaces can present significant roof and eaves ventilation challenges. Drawn to colder roof spaces by convection, condensed water vapour can lead to rotting timbers, rusted metal fixtures and felt damage from mould growth. The gap between a house’s roof and a house’s ceiling is called the roof void. In most houses, this is the loft or the attic. In houses with flat roofs, there is no roof void and roof vents are not needed. The position of the roof void means that it needs ventilation to prevent condensation. Without this, the rot will begin to set in in the timbers of the roof and spread to the rest of the house. The EasyVent is both innovative, inexpensive and inconspicuous. Just like Manthorpe vents, they are installed on the inside of the roof, in between the overlap and underlap of the felt lining or membrane.

Our sales office will need to be made aware of any delivery restrictions, such as narrow lanes, overhanging trees etc. that may cause restrictions.

With three felt clips that secure the vents in place, regardless of whether felt edges are jagged or deteriorated, these vents are often fitted retrospectively to buildings where extra loft insulation has recently been installed. Though, they can also reduce condensation build-up in any roof space that features a lapped felt/membrane structure. Features & Benefits: Manthorpe Felt Lap Vent (Box of 50) Simple to install even for a DIY Enthusiast, the vent simply slides between the two layers of underlay felt beneath your existing roof tiles or slates. They can be installed from inside the property so no need to remove any of the existing tiles, timber battens or felt. Important loft lap vent installation notes There are many products available to help you stop loft condensation, and most of them are inexpensive.
