Considering fascia board is an important part of construction, not many people know what it is, what type to buy, or where it is installed. Furthermore, the terminology that comes along with it can be just as confusing. Timber 2 U Direct are going to talk through this element of roof construction and ensure you know everything you need to about installing your own boards.
What is Fascia Board?
Fascia refers to the horizontal board that is fixed along the rafter ends of the eaves on your roof. This closes the gap between the walls and the roof and prevents water seeping into your roof, and therefore loft space. It can sometimes be referred to as the roof line and is also the part of the structure that holds the guttering in place.
There are a couple of different types of fascia board, but they are usually made from either wood or uPVC.
Wood fascia type is the most common and as you can imagine, the most traditional. It is also the most cost-effective option when compared to the other materials that are available. Any wood used for these boards must be primed to ensure it is water-resistant and thus will not rot. Wooden fascia boards are also versatile as they can also be painted. This option is also available in many different types of wood, dependant upon the style you are looking to emulate.
If you choose to install wooden fascia boards, you will need to re paint them periodically to avoid the absorption of moisture and to prevent cracking. If this is not remedied, serious damage could be caused to the building, including insects getting into your home, or water damage.
uPVC is an becoming an increasingly popular option for fascia boards. This is due to technology and manufacturing improvements that allow it to be produced in different styles, shapes, and colours. Choosing uPVC lets you completely customise your roof edging and therefore achieve whatever vision you have for your home. This is something that is harder to achieve with a wooden fascia. uPVC will not rot or warp over time and is almost maintenance-free.
Unlike wood or other counter parts, uPVC is not eco-friendly, despite lasting longer. It also looks significantly more artificial than wood; so if you’re going for an organic look and feel, this will not suit your home.
Flat fascia boards are the most commonly used boards and give a classic feel to your roofing. These have basic flat edges along the lip.
These are similar to flat boards, but they have a slightly longer lip, and as such they give off a squarer appearance.
What is a Soffit?
A soffit is similar to a fascia, but it doesn’t run parallel to the walls. Instead, they are installed at a 90-degree angle. These are placed underneath the fascia boards in order to fill in any extra gaps. This gives the roof a clean finish whilst providing the correct ventilation. The soffits draw fresh air into the roof space whilst allowing warm and moist air out. This will reduce the risk of mould and damp in your loft. For every 150 square foot of loft space, you must have one square foot of ventilation. These should be evenly spaced out throughout the roof.
Best Timber for Fascia
If you settle on using timber for your fascia board, there are a few options. Timber 2 U Direct would recommend settling on hardwood as these are usually more durable than softwood and as a result will last longer. Timbers such as Cedar and Redwood are popular choices due to their exceptional resistance to rot. However, if how the wood looks is a consideration, and you are willing to coat the wood in primer, timbers like Fir and Pine can also work beautifully.
When ordering timber for your fascia board, it is advisable to make it a little longer than necessary to ensure it can be trimmed to the correct size. Your boards also need to be at least 16mm thick to meet BBA approval. This is the required thickness to ensure that if you nail a board directly to the rafters, it’ll be strong enough to hold any guttering you attach.
How To Fit Your Fascia
Step One: Prepare Your Roof
Before you start the installation of your fascia board, you need to prep the roof. you must remove the bottom row (or two) of tiles. If you have any existing fascia, soffits, or guttering, this must also be disconnected. Ensure you inspect the rafters for any damage before you proceed.
Step Two: Measure and Attach Your Fascia Material
Cut your timber to the correct length and width. Make sure the wood isn’t too wide and doesn’t block any windows or openings. Now, nail the board to the rafters with stainless steel nails. Each rafter should be fixed with evenly spaced nails.
Step Three: Add Soffits
Measure and cut your soffit to the size of the space available inbetween the fascia and the wall. Ensure all gaps are filled, as failure to do this can invite moisture in and could result in damage.
