Most homeowners dread the prospect of hearing their roofers say they need a roof replacement. Roof replacement projects cost a pretty penny. However, they are often necessary and more convenient in the long run than a series of increasingly frequent small repairs. What all is included in a roof replacement?

What is a Roof Replacement?

When your roofer says your roof needs a replacement, they mean everything from the roofing material to the roof deck needs to get torn off. Then roofing underlayment is applied to protect the roof deck from water damage. And finally, the new material gets installed.

According to Remodeling Magazine, roof replacement has an average ROI (return on investment) of around 60%. Therefore, you can turn this project into an investment, especially if you plan to sell your house.

Fundamentals of Total Roof Replacement

Some of the fundamentals of roof replacement include:

Roof Material

Your roof has an outermost visible layer of material, like shingles. These are what do the heaviest lifting and make your roof more durable, waterproof, and fire-resistant. This is why they are essential and need utmost care.


Your roof consists of wooden framing boards know as decking. The material gets installed on top of these boards. More often than not, roof replacement involves replacing your roof’s old decking, especially if the boards are rotten.


The underlayment is vital to avoid water leakages, damage, and the growth of mold and mildew.


Most roofs have metal strips installed wherever the roofing material meets structures such as the chimney or valleys. These are known as flashing.

If your old roof has corroded flashing with compromised integrity, it will have to get replaced. The same applies to the drip edge flashing installed to direct water flow on your roof.

Ice and water shield

Ice and water shields are the waterproof membranes present on your roof. Their purpose is to protect the roof components against damages from excess water and ice.

Without quality ice and water shields, harsh elements will damage your shingles and lead to disastrous leaks.
