Whether you're replacing your existing roof due to aging, damage, or aesthetic reasons, it's important to consider all the components of a residential roof replacement. Not all components need to be replaced, but some may require special attention. Some common components prone to wear and tear over time are the roof deck, underlayment, flashing, and shingles. A roofing contractor can advise you on what should be replaced and what can be left in place. Keep reading to learn more about the four components you should consider replacing during a residential roof replacement.

Roof Deck 

The deck is the underlying structure of your roof that reinforces it and provides a base for shingles and other components. A damaged or deteriorated deck can lead to leaks, damage to the home's interior, and other problems. Therefore, if your roof deck is in bad shape, you should consider replacing it to ensure your home is fully protected. You can replace it with plywood, OSB board, or metal.


The underlayment is the material between the deck and shingles that helps keep moisture away from your home. It also helps reduce air leakage, sound transmission, and heat transfer between the roof and the interior of your home. When replacing your roof, you should consider replacing the underlayment if it's old or damaged. Common materials used for underlayment include tar paper, synthetic felt, and rubberized asphalt.


The flashing is the metal material that helps create a seal between different roof components, such as at the eaves and around vents and chimneys. If the flashing is damaged or deteriorated, it can create gaps in the seal, leading to water leakage and other problems. Therefore, you should replace any damaged or deteriorate flashing to ensure the seal is intact. You can use copper, aluminum, or galvanized steel for your flashing.


The shingles are the visible roof covering that protects your roof from the elements. Replacing your shingles allows you to upgrade to more durable and attractive materials, such as asphalt or metal roofing. Replacing the shingles is relatively easy if you have the right tools and materials. However, you should always consult a professional if unsure of the installation process.

When replacing your roof, it's important to consider the four components mentioned above. A roofing contractor can help you determine which materials are best suited for your home and what needs to be replaced. They can also provide you with an estimate of the cost and time involved in replacing these components. Considering these factors, you can ensure your roof is fully protected and ready for whatever comes.
