If your roof is too old or very damaged, you might need a roof replacement service. Perhaps you simply want to change how your house looks or boost its value. No matter what your aim is, a roof replacement is among the best ways to ensure safety and increase your home’s value and beauty. Here is what you should expect during a roof replacement project!


Removing All Shingles

During a roof replacement process, you will need to remove all your existing shingles so that your new warranty becomes valid. If you have old valley flashing or drip edging, you should also expect to have these removed.

The roofing team will then use tarps to protect the foundation and other safety features. You can sometimes expect to see some magnetic tools on the field. They are meant to pick up nails or other metal objects from the construction site.


Initiating Minor Repairs

Once the existing shingles are removed, the roof crew will perform minor repairs if necessary. For example, you might replace some wood parts with new wood or sheathing boards, depending on what works best for your new roof.


Ice Dam Protection Installation

Some regions of your roof will require ice dam protection. It is like a waterproof barrier meant to prevent any melting ice from getting under your shingles and causing water damage later on. This is a crucial component to ensure protection during and after the winter seasons.


Placing Asphalt Roofing Paper Over Roof Sheathing

Next up, the roofing team will place roofing papers to create another barrier against water. These rows of paper overlapped, progressing upward toward the peak of your roof.


Drip Edges

Once the roofing paper is installed, the drip edges are placed over them and around the edge of the roof, on eave sides and gable sides, and are nailed in place. The drip edges are meant to divert water from your roof’s structure.


New Valley Flashing

In some instances, during a roof replacement project, you might also need to install new valley flashing. They are placed where roof planes meet and nailed to the roofing deck. A roofing caulk is also used as a sealant.


Installing Tab Shingles

At this point, the roofing team will begin installing the shingles you chose for your new roof. They will start working on the eaves and going upward towards the roof peak. If you have roof vents, the shingles will be installed from the bottom all the way up.


Applying Flashing

There are many areas around your roof where leaks could start to form, and this includes around the chimney, skylights, or stack vents. However, new flashing will be applied all around these points to prevent water leaks. In some instances, you can expect the flashing to be installed as the rows of shingles make their way upward on the roof deck.


The Ridge Vent

The last essential step during a roof replacement is installing the ridge vent. It is meant to help air circulate in your attic and will play a crucial role against ice dams and hot air. If your roof can’t sustain a ridge vent installation, there are other options to choose from, so make sure to ask your roofing contractor about them.


Getting Rid of the Debris

Finally, once the roof replacement is completed, the roofing company will proceed with getting rid of the debris on the construction site and cleanup.


Other Things You Need to Know

Replacing a roof can take a couple of days or more than a week, depending on the roofing company you work with, what type of roof you want, the weather, and other foreseeable and unforeseeable conditions.

When it comes to costs, it also depends on what type of roof you want, the materials, the roofing company you work with, what other features you want, and what damage needs to be fixed. Usually, in Portland, the average cost of replacing a roof is around $15,000.


Choosing a Roofing Company

To ensure that your new roof will last, you don’t have to make sure that you work with good materials because the team behind the installation is just as important. You should focus on working with GAF-certified experts if you want to be sure of quality. Only 6% of roofing contractors receive this certification.
