So, you want the old roof in your house removed and replaced with a new one? Well, good for you! But do have an idea on the basic terms that are used in residential roofing or the materials that go into it? If you are like me, then you have limited knowledge on the terms and materials often used in residential roofing or worse, you have no idea what goes on when it comes to the actual roofing. Here is a brief overview of some of the commonest materials and terms used in modern day residential roofing, and how they are applied. 1. Plywood roofing material This material forms the base layer on top of most roof trusses. A 4" x 8" sheet in measurements, plywood is a perpendicular layer that is added to the roof's trusses for strengthening purposes. Plywood clips are often utilized between the next vertical sheets normally in-between the trusses so as to allow a 1/8" space for expansion. 2. Tar paper or felt roofing material Felt or tar paper is a roofing addition that comes in two measurements; 15lb. and 30lb. 30lb. variety is preferred by a majority of roofing experts as it is much stronger and thus more durable compared to the 15lb. variety. Tar paper must be applied where the aforementioned winter guard is stopped and once again perpendicular to the roof trusses. When you are applying the said felt, start at the bottom continuing to the top of the roof ridge making sure that the next piece is correctly lapped but at least two inches over the top of the last piece. This is important as it ensures that if any water manages to get under the shingles, it easily runs down the roof without getting under the felt material or tar paper. 3. Winter guard A winter guard is only used in cold climates and is fixed on top of the plywood at the bottom of a roof and is also set perpendicular to the roof trusses. To ensure a more solid seal, to the underside of a winter guard is an appropriate tar that holds fast to the plywood material. The winter guard must be installed extending past the eave so as to ensure that during long winter season there is no building up of ice dams. Moreover, air chutes have also to be installed between each and every truss and on the plywood underside into the soffit so as to allow for unhampered air circulation, thereby helping in ice dam prevention. 4. Shingles Shingle is a common term used in most roofing undertakings. There are a number of different kinds of shingles in the market today that can be used in roofing undertakings, among them, asphalt shingles. Shingles go over the top of the winter guard and the felt. Similar to felt and winter guard, shingles are installed perpendicular to the roof trusses. They are once again applied starting at the bottom to the top of the roof. However, it should be noted that the first row of shingles require a starter strip underneath them with the right tar application in order to ensure that they don't end up curling up and thus becoming exposed to the weather elements. I'm sure you won't want to use a Nashville roof repair company who is not familiar with these terms!
