The Woodlands Roofing: Article About Roof Components
The Woodlands roofing experts install similar types of residential roofs. In fact, construction techniques have been virtually the same for decades if not centuries. Many components make up a typical residential roof. A homeowner considering a roof replacement or planning a new construction should familiarize themselves with the different elements that comprise a system vital to the integrity of the home.
The part of the roof put on last and most visible is the covering. This can consist of one out of a variety of materials. The most commonly used type of covering is the asphalt shingle. However, clay and concrete tiles, metal, slate, polymer plastic and wood shakes are also popular choices. The main contributing factor for a homeowner deciding on a type of covering is typically the price. Certain materials are far more expensive than others are.
The covering goes over an underlayment, which is typically a black paper meant to function as a membrane to prevent water leaks. This water resistant barrier includes other elements such as flashing and sealant. The entire underlayment is intended to accomplish three major functions: waterproofing, sweat sheet and vapor barrier.
Below the underlayment lies the sheathing.

In typical installations, this is plywood sheeting nailed and screwed to the support structure or rafters. The sheathing is one of the main components of a roofing system and provides a medium to which the underlayment and covering may be attached.
Under the sheathing lies the main support structure for the entire roof system. This can be either rafters or trusses depending on the design plans. Rafters or stick-framed roofs require certain support elements depending on the weight of the covering. For example, asphalt shingles are relatively lightweight and can be supported by a simple support structure. However, heavy covering types such as tile or slate require a bulky and heavy-duty support structure. This can mean the difference between an inexpensive roof and one that can cost an arm and a leg.
There are other design elements of a roof system. These include the ridges, hips, valleys, eaves, gables and dormers. All of these elements are designed to properly shed water from the house. The more complicated and "cut-up" a roof system is directly relates to its cost. An a-frame roof with two gables is a lot easier to build than one consisting of many hips, valleys and multiple ridges. Homeowners should consider all the options and design schemes in order to achieve the best roof system for their homes.
