I'm right to say that it's a system because there's a lot more on your roof than just shingles. I know most homeowners believe they have received a new roof when they removed old shingles and installed new shingles because that's what their roofing company told them.
However, there are several different components of your roof and different functions of these components, that is why it's called a system.
Take a look at a complete roof system
Your complete roof system is composed of different components with different functions, the system is assembled in layers with each layer protecting your roof system. the house in different ways and different weather elements. I will refer to these functions as sealing, defending and breathing.
Now let me see what I mean by Seal, Defense and Breath:
- Underlay – There are several different types underlayers such as # 15 and # 30 felt papers and synthetic roofing underlayments, all of these underlayments are designed to protect your roof from moisture and damage and offer another level protection against the elements. These components are also very important because they help in an asphalt shingle roof assembly to get its class A fire rating.
- Self-adhering membranes such as frost shield and Aquatic, WeatherLock and StormGuard (depending on the shingle making that you use) offer a higher level of defense against ice and water. They are usually located in areas vulnerable to ice and water, such as along the perimeter of soffits, eves and valleys.
- Starting Shingles – These shingles are installed along the perimeter of your roof they seal in the first row of shingles and help secure the shingles and provides greater wind resistance .
- Shingles – This is what everyone sees when they look at their roof and perhaps the only component that homeowners consider when they get a new roof. There are many styles, classes and classifications for shingles, so it's wise to find as much shingle as you can before choosing the color.
- Ridge and Ridge Shingles – Shingles that cover the top and roof contours protect against rain and wind while enhancing the overall appearance of your roof by giving it a high degree of comfort. finished appearance.
- Ventilation – This is a very important part of your roofing system as it is important for your home to breathe. A properly ventilated roof will help improve airflow and protect it from damage from heat and moisture. The ventilation of your roof also vents your attic which includes air inlet (soffit vents) and exhaust vents (vents, turbine fans, vents) to help control the flow of air. Air and help prevent mold.
There are also other necessary components of your complete roof system that must be replaced and / or installed when you have finished your roof. These components are the drip edge, the pipe flashing, the chimney and the wall flashing to mention a few. These components are very important because they help you to have a secure and well protected roof.
Now that I have described a complete roofing system, I discuss a "marked" roofing system
A "Marked" roofing system follows the same design that a complete roof system. The branded roof system will use materials specific to manufacturing. GAF and Owens Corning (to mention two) are domestic manufacturers and two of the leaders in the roofing materials industry. By using the specific products of the manufacturer such as; shingles, starting shingles, hip and ridge shingles, synthetic underlayments, ridge vents and self-adhesive membranes, you will have a complete "marked" roof system.
You may wonder, why is the complete "Branded" roof system better? The manufacturer has designed and developed these products to work together for the highest level of protection in your home. While similar low-cost materials collected from different manufacturers are not designed and developed to work with each other, they will not provide protection to your home as a complete "Branded" roof system.
