If there’s a key component in a house that endures the harshest weather and other dangerous elements outside, that would be the roof. That said, the time will come when roof maintenance and repairs/replacement will be needed to maintain the good integrity of their roofs.

But year after year, many homeowners fall victim to roofing scams. And truth is, these scammers targets homeowners who are on a tight budget when it comes to roof repairs.

One of the ways to combat these schemes is to be a knowledgeable consumer. Having an idea or two about roofing will help you understand the process, and you can also convey your preferences to your roofing contractors.

The best way to start learning is to know the roofing system. Here are the important and major components of a roofing system and their functions:

Roof covering

Roof covering is the most visual part of the roofing system, thus most people think that roof covering is just the roof. But actually, it is composed of rafters, trusses, and other supporting structures that will give the roof its strength and shape.

The roof covering has two functions. One, and the most important function is to protect all the elements under it. Second, roof covering can add appeal and style to your home. That is why selecting good-quality roofing material is crucial, especially if you are getting your roof redone.

Roof Underlayment

Roof underlayment is a sheet that is laid on the surface of the roof deck. This is done before the installation of the roof and most likely it is hidden. The common underlayment comes in three different types: Asphalt-saturated felt, synthetic underlayment, and rubberized asphalt underlayment.

The underlying adds an extra layer of protection and offers durability. It can be water-resistant or waterproof, depending on your priorities.


Some parts of the roof are prone to water leakages like chimneys, roof valleys, and the intersection between the roof surface. This is where roof flashing comes in.

Roof flashing is the small sheets of galvanized steel or aluminum installed in the parts of your roof to prevent water leaks. The flashings must be installed correctly to ensure that all the water will fall to the ground.


The sheathing is usually made of wood or metal that acts as a flat surface to hold underlayment and shingles. That said, sheathing should be of high quality as it supports the rest of your roofing system.

Insulation and Ventilation

Cooling and heating account for approximately 48% of the overall energy consumption. That said, we’ve included insulation and ventilation as an integral part of the roofing system.

Insulation helps you control the interior temperature of your home, thus it saves you from using too much heating and air conditioning.

Your roof also needs a protector and that would be the ventilation. Vents help reduce humidity and condensation in your home’s attic, preventing molds and another build-up that will affect the durability of your roof.
