Fascia boards are located on the eaves. They are fixed on the edge of the roof structure at the lowest end. The eaves commences from the fascia to the building wall. The boards are usually made of timber but other materials like steel sheets, gypsum, glass or plastic are also used. he size of the board is from four inches to twelve inches wide. The thickness is one inch. The boards are chamfered at the bottom and cut straight at the top.
The fascia boards are fixed below the roof covers like tiles or iron sheets. Wrought timber is used for making fascia boards. The finishing is usually of gloss or oil paint in at least three coats. On multi story homes or buildings,it is important to fix them before laying the roof covers. This is to ensure that they are correctly aligned. The boards are used to carry the rain water gutters that are placed on the roof structure.
The fixing of fascia boards commence after the roof structure is ready. A string is tied from the first rafter to the last for straightness. Since the rafters are pitched they are cut along the string line at ninety degrees. This ensures that the boards are fixed perpendicular to the wall and at ninety degrees upright. This also avoids the use of wedges behind the boards for alignment purposes. A forty five degree cut is made on the boards for jointing.
The fascia board is fixed to the rafters by nailing. The nails are done half way into the rafter. The boards are the adjusted for straightness and plumbness before finally hammering them all in. At the corners where a sloping verge board on a gable side and the fascia meets, the sloped board is cut at angle of the pitched roof. This allows a smooth joint. When the boards are in place then the roof covers are done. Finishing is done using gloss paint.
Painting wooden fascia might be a waste especially if you have used strong and attractive kind of wood. It would be a shame to apply paint on the wood. If you want to accentuate the style and the rustic appeal of the wood, try staining it instead of painting it. Use tea to stain wood. It accentuates the rustic curves and lines as well as gives the wood a natural shine. However, you might want to use some sort of staining product incorporated with additives to make it more resistant to external wear and tear.
