A bonus fourth type of roof vent. Lap vents such as Manthorpe’s Felt Lap Vent are by far the easiest to install out of all the types of vents mentioned above. They can be easily slipped in between a horizontal overlap of your undersarking. This creates an air pathway which can help combat condensation build up. Initially, it is recommended that one vent be placed into the laps in every other rafter bay as close to the eaves as possible, but more can be installed in extreme circumstances. It should be noted that these vents alone will never provide adequate roof ventilation and should always be partnered with the options listed above to create and suitable amount of ventilation. How Much Do Roof Vents Cost?

Regardless of the approach you’d like to take, it’s always best to err on the side of caution. If you install the wrong number of vents in your roof it’s far easier to add more than to remove ones that are already installed. Hambleside Danelaw’s range of tile and slate vents provide ventilation into the roof void, and can also be used with mechanical extraction in bathrooms or kitchens or used for soil ventilation. All of these functions are achieved by the use of an additional flexi-pipe adapter kit which connects the required service to the vent terminal, thereby removing unsightly penetrations through the roof.

Vented roofs allow heat to escape the space with ease. This can, in turn, reduce the need for solutions like air conditioning to lower bills. The life of the roof is extended There are a wide variety of roofing vent types available. Here is a brief overview of the most common. Roof tile vent Alongside the tile and slate vents, Danelaw offers a range of eaves and soffit vents, CON6+ and CLAY6+; the ventilated dry fix ridge and hip systems. Roof tile vents can be universal and handy when incorporating ventilation into your roof. They are typically easy to replace and, due to their universal manufacturing, added to any brand of roof vent compatible with the tiles you choose. A third option, useful for retrofits or when replacing fascia boards, are over fascia vents. These provide highly discreet ventilation, along with features designed to repel unwanted visitors such as birds and insects. These vents are made from small units that clip together and are nailed over the top of your fascia boards. Installing these roof vents is difficult, but highly effective when done right. Lap Vents

Roof tile vents help to reduce condensation in your loft space and ensure you get a long lifespan from your roof. Adding tile vents to your roof space can prevent timbers from rotting, saving you from expensive future roofing repairs.As opposed to traditional wet fixed ridge vents, Timloc have manufactured a highly convenient dry fix ventilated ridge kit, designed to be easy to install whilst still providing an impressive 5000mm²/m of ventilation. This is an ideal solution for DIYers looking for a low maintenance roof ventilation solution. Eave Vents Ridge vents can be installed by securing them to your roof ridge above suitably cut roofing felt or undersarking. These vents provide an impressive level of ventilation, but can almost never be used as a singular vent, but rather as an exit for rising air. Be aware that it is possible to install too many ridge vents however, particularly when it is very windy. This is because for homes with many ridge vents partnered with large eaves vents (a common occurrence in new builds), too much air can enter your loft space, potentially blowing your insulation about at the edges and causing damage.

The vent turbine is a fantastic solution for those looking for a more eco-friendly source of ventilation. Not only does it use the wind to rotate the ventilated air in and out of the roof space, as a result, but this can also be fantastic for reducing your electrical costs. A dry ridge vent system is mandatory for all new roof installations in the UK. They are installed without the use of mortar. A mortar is a wet ridge used to support this type of vent. Once you’ve got a clear idea of the ventilation your roof requires and how many roof vents you need, you can start looking into the types of roof vent that are available. One thing to remember is always to take care when working in loft spaces. Types of Roof Vents It can be difficult to say how many tile vents your home will require. In general however, two vents on the front of your roof and two at the rear should be a good starting point, perhaps also in conjunction with some ridge or lap vents. Ridge VentsThis is the key figure in determining how many vents you’ll need in your roof. For example, a normal roof with a pitch over 15 degrees ( find out how to calculate your roof pitch) will require free airflow equivalent to a continuous 10mm opening (10,000mm² per metre run), so if your roof is 5000mm long you’ll need 50,000mm² of airflow. How Much Ventilation Do Different Vents Provide? Step two: Work out the number of vents required, asking how many vents it would take to provide the same amount of airflow: Our roof tile and slate vents have undergone vigorous testing at the Building Research Establishment (BRE) to strengthen the design features of the final products and compatibility with surrounding roof structure.
