Replacement Process a Shingle Roof

Replacement process a shingle roof from Republic Roofing. Of all major home improvement projects, installing a new roof is certainly the most important one. However, due to the exorbitant cost or high complexity of such projects, undertaking a total roof replacement project is often the last thing on the minds of homeowners. After all, a roof replacement is a large-scale project that can create a huge mess in your home if not handled professionally. While such projects are not as exciting as other home improvement projects like a kitchen renovation, a roof replacement can become a necessity sometimes. 

Once you get a stunning brand-new roof, the benefits go beyond just aesthetics. Apart from boosting the curb appeal of your home, a beautiful and durable shingle roof can provide you with superior protection against the elements, improve comfort levels in your home, and make your home more energy-efficient and environmentally friendly.  


Many homeowners want to replace their old and inefficient roofs, but they just don’t know where to start, what should be replaced to maximize their investment, and how much it will cost them, and so on. 

 At Republic Roofing, we understand these concerns. In this brief roof replacement guide, we have listed all the crucial components of a typical roof replacement project. Let’s dive right in. 

What Is Included in the Shingle Roof Replacement Process?

1. Tear-Off

Before installing a new roof, your roofer needs to perform a roof tear-off. They will remove your old roofing shingles entirely. A roof tear-off before a roof replacement has some great benefits such as:

  • High-Quality Installation. By stripping your old roof down to the deck, professionals can find and repair any underlying issues. They will then install high-quality flashings to achieve watertight protection for years to come.
  • Long-Lasting. A total roof replacement that includes roof tear-off has a much longer lifespan than re-roofing with multiple layers. A brand-new roof that is installed from scratch doesn’t trap much heat and therefore the shingles stay protected throughout their lifespan. 
  • Enhanced Home’s Value. If you are planning on selling your property soon, a brand-new roof can help you attract more potential buyers and sell your home quickly and at the best price possible.   

2. Deck Inspection

The decking of your roofing system is there to provide protection and structural support to your roof. To perform optimally, your roof must have strong and sturdy decking. That’s why it’s important to conduct a decking inspection before installing a new roof. In case, your existing decking is in good shape, you can use it to install a new roof without any trouble. However, if it is damaged or rotted, make sure to get it replaced for long-lasting results. 

3. Installation of Underlayment, Flashing, Drip Edge

  • Underlayment: The new underlayment will be installed between the shingles and decking. Underlayment serves as a waterproof layer for your roofing system. 
  • Flashing: Flashing is a thin piece of metal that is installed around the most vulnerable parts of your roof such as chimneys and skylights.
  • Drip Edge: The drip edge is installed to keep your roof dry in heavy rains. Installed around the roof’s perimeter, a drip edge is used to direct water away from the roof so that it doesn’t seep into the inner layers of your roof and cause issues like roof leaks. 

4. Installation of Shingles and Vents

Now comes the most important part of any roofing system: the shingles. Once your roof has been torn apart, professionals have conducted your decking inspection, and components like flashing, drip edge, and underlayment are installed successfully, your new shingles will be installed. 

Professionals will install your shingles section by section along with other components to cover every nook and cranny of your roofing surface for impenetrable protection against the elements. However, experienced roofers also ensure proper air circulation in your attic without compromising the waterproofing abilities of your new roofing system. 

Some of the effective ventilation options:

  • Ridge vents: Generally installed on the highest point of the roof, these vents provide continuous exhaust ventilation in the upper portion of your attic. These vents are designed to withstand heavy rain and high winds.
  • Gable vents. These vents can be seen on the exterior walls of the attic. Apart from achieving proper air circulation in the attic, these vents also serve as an architectural element. 
  • Off ridge vents. These UV-resistant vents serve as a static ventilation system. These are normally installed on sloped roofs. 
  • Mechanical vents: Mechanical vents use wind as their power source to remove heat and humidity from the attic. Whirlybird vents are a common example of mechanical vents. 

5. Clean-Up

After the successful completion of the installation of your new roof, your roofing company will start the cleanup process. The process usually starts with removing every bit of debris from your roofing system and gutters. They will then clean the ground and landscaping. The process needs to be repeated 3-4 times to make sure that they do not leave behind any kind of discarded materials, metal scraps, or sharp objects anywhere on your property.
