Having a Solid Understanding of the Residential Roof System
Admin Admin July 25, 2022

Have any experience conversing with someone and not understanding a word they were saying? Did you happen to be talking about residential roof systems?

I would be the first to acknowledge that, similar to many other fields of work, we have our own jargon that we employ and expect others to comprehend just because they are nodding their heads. However, that would not be fair to you. When it comes to your house, you have every right to know what a project manager or salesman is talking about regarding your property.

The following is some essential information to help you have a better grasp of the residential roof systems so that you are better prepared to speak with roofing professionals.

residential roof systems

1. Roof structure

The roof is supported by the structure of the roof. The form of your roof is defined by the rafters, trusses, or beams used in your house construction. Most of our area's home roofs are wooden (compared to steel used on commercial projects). The structure of a home's roof is determined by the home's plan and the ultimate roof covering. Because of the additional weight, a house with concrete tiles is different from one with asphalt shingles. The slope of the roof is also determined by the roof structure.

2. Roof sheathing

The roof sheathing is what you notice while driving by a house under construction and seeing just flat sheets of material on top of the structure. It's attached directly to the roof and sits on top of it. Oriented Strand Board (OSB) is the most used material since it is lightweight, inexpensive, and economical. In addition to concrete tiles, plywood is sometimes utilized as a roofing material because of its greater weight-bearing capacity.

3. Roof flashing

Every roof would have a little slope if there were no barriers in an ideal roofing world. However, this isn't the case at all. Chimneys and ventilation vents are examples of structural elements found on roofs. In certain situations, flashing protects the roof from water damage. Its primary function is to keep water out. The majority of flashing is made up of a thin metal strip. There are troughs and protrusions where water may be diverted and flow down the roof. The specific form of flashing is usually decided by the roofing firm.

4. Roof ventilation

Ventilating your roof is essential. In addition to extending the roof's life, it decreases energy costs and lowers the temperature inside the home when done correctly. Roof vents are divided into two categories: exhaust vents and intake vents. In many cases, roof vents are positioned behind the roof covering, so they can't even be seen from the street. When properly built and installed, the ventilation system enables warm air from the attic to be expelled and cold air to be drawn in.

5. Roof covering

Your roof is the outermost layer of your roofing system. In the United States, asphalt shingles are the most common roofing material because of their low cost, fire protection, simplicity of installation, and long-term performance. There are, however, alternative possibilities. If you're building a new house, here are some materials to consider:

Asphalt or wood shingles

Clay, slate, or concrete tiles


Flat roof coverings - PVC, Rubber, Spray foam, Tar, and gravel

6. Roofing drainage

It's important to remember that roof drainage is all about effectively removing water from the surface. When it comes to residential roofing, where sloping roofs are typical, it's all about channeling rainwater to the correct roof regions and preventing it from gathering and causing leaks.
