Dallas Roofing: Article About The Layers Of A Roof
When a person looks at the components of their home from the outside, it is easy to see why they would miss the overall importance of the roof on their dwelling. When all a homeowner sees are shingles, they miss all of the other layers that go into completing a solid roof. Each portion plays a role in securing the integrity of a roof and ensuring that the inside of a house stays dry and free from outside weather. If a homeowner needs to contact a Dallas roofing company about replacing or repairing a roof, it is good to know all of the layers that make up the structure.
The first aspect of a solid roof is the framing and rafters that it sits on. This provides a firm foundation and area of support. A roof is only as good as the structure that it sits on. It is important that the support structure is strong enough to hold it up, because some roofing materials such as slate tiles require a stronger area of support.
In the past, energy efficiency wasn't as important as it is now. Older homes may not have had a layer of insulation placed between the rafters of a home. Now though, insulation on the underside of the roof is more commonplace.

With the advent of spray insulation, many homeowners are taking advantage of this option to cut down on energy costs.
A layer of decking sits on top of the rafters in a home. Also known as sheathing, it creates a broad surface for other layers and acts as a first line of defense against outside weather. Decking can be made from many different types of materials that range from plywood or metal to OSB sheets or roof pavers.
Underlayment is attached to the decking of a home. This roofing layer comes in different materials that range from synthetic to felt that has been saturated with asphalt. Typically, the underlayment layer is used as a backup and provides extra protection against winds, fire and wet environments.
The majority of roofs will have an outer layer that is composed of shingles or tiles. Roofing materials can range from asphalt or metal to clay, slate, concrete or wood. Styles are chosen based on price, life span, durability and aesthetics. This layer is the first to get hit by high winds, sleet, rain or heat from hot summer days. This layer will also include flashing. It is placed against other structures such as dormer windows, vents, skylights or chimneys.
