Learning the parts of your roof is very important, especially if you are buying an older home. Understanding the different roofing parts in your older home will assist you in knowing your roof's structural integrity and which changes you need to make.
Here are some tips of what you need to know.
Truss – the skeleton of your roof is the plywood lying under the roof. Check to see whether the plywood is solidly nailed to the truss, which is also known as rafters.
Sheathing/decking – in many homes, decking is the plywood that is fixed to the rafters. You should inspect to see whether the decking is firmly fixed to the truss. In case you realize that it is loose, then you will be required to repair that part.
Drip edge – drip edge is the first thing that you will see when you look at the roof of the old house you buy. However, you need to understand that it isn't there for cosmetic appeal only. Drip edges prevent water from running back to the truss.
Soffit – the soffit is a great place in the roof where many birds as well as other creatures like to nest. Soffit is the space beneath your roof's overhang, and it should always be closed off. However, it has small ventilations to allow air to circulate in your house. Check to see whether there are any creatures living in the soffit.
Ridge – the ridge is the top most point of the roof. See whether the ridge has a cap or the required material to prevent water from leaking into the roof.
Flashings – these are the metals fixed around vent pipes, roofline intersections, and chimneys, amongst other areas. Flashings ensure that water doesn't drain into the joints.
Valley – this is the point where the two slanting slopes of the roof meet. The valley should always be kept clean to prevent wood or shingle rot. Also, check to see whether the shingles and wood in the valley are in good condition.
Fascia – the fascia is the edge of the rafters, beneath the roofline, where the gutters are connected. Waterlogging is one of the major problems that affect fascia boards. Check to ensure that they are in good condition.
Underlayment – this is the material found beneath the shingles, and it protects the sheathing or decking from moisture damage. Whenever you notice that the underlayment is visible, consider hiring a roofing professional to repair that part.
