How Roofing Installation Works?

May 9, 2025

A roof is one of the most important parts of your home, as it protects you from the elements and can help maintain the value of your property. No matter what style or size of roof you need, it’s important to choose a good contractor to do the installation work for you—and to know what to look out for so that you can find someone reliable and trustworthy. Here’s how roofing installation works in three simple steps.

Planning is key

Roofers install new roofs as a part of a regular process called roofing installation. It involves planning, equipment, materials and skills in order to build something that is not only functional but also attractive. The first step is know the best time to replace a roof shingles. The second step is to determine what type of roof will be installed on top of an existing structure. The most common types are shingle, tile or metal; each has its own pros and cons when it comes to cost, durability and maintenance requirements. Once a type has been selected, it’s time for preparation: If your home’s old roof needs replacing because it’s worn out or damaged beyond repair, there may be some demolition work involved before you can begin installing your new one. This includes removing any existing nails or screws holding down shingles or tiles so they don't interfere with construction later on.

Getting your house ready

Preparing your house for new roof installation is vital to ensuring a quality job. Be sure to have any nails or screws removed and plan ahead in case of any necessary repairs. If you’re re-roofing an existing house, it may be necessary to remove some of your old shingles before getting started with a new one.

The crew arrives

Once you’ve chosen a new roof, it’s time to start scheduling for your crew to arrive. A standard job will require at least two men, and some jobs may need up to six people depending on complexity and scope. When you set up your appointment, confirm whether or not there will be an additional fee for travel expenses from their headquarters to your home. This is usually only needed if they are more than 15 miles away from your location.

Installing the underlayment

The underlayment is a sheet of material (generally felt) that sits between your home’s siding and your shingles. While it may seem like an unnecessary step, it serves several important purposes. For one, it creates a moisture barrier, preventing water from seeping into your home through holes in your siding. Secondly, and more importantly for many homeowners, it acts as a sound proofer.

Roofing Installation Begins

A professional roofer begins by performing a shingle inspection and looking for potential problems like mold, moss, cracks, or worn-out materials. A skilled crew will measure your home’s dimensions to ensure they have all of their materials before starting work on your home. They can also use these measurements to develop accurate pricing estimates based on how much labor will be required to complete a full-service installation.

Trimming the edges

One of your first steps in installing a new roof will be removing any old sheathing and/or attic insulation. One of your first steps in installing a new roof will be removing any old sheathing and/or attic insulation. If you’re working with an older home, you may find that some areas are already insulated with fiberglass batts, which can make it easier to install your new roof. In these cases, there’s no need to remove all of the old insulation—just trim off what needs to be trimmed off to accommodate your shingles or metal panels.

Clean up and finishing touches

While a company or contractor may have installed your shingles, there’s still work that must be done after they leave. To prevent leaks and water damage to your home, you’ll need to pay attention to a few details . The first is making sure that all nails are hammered in completely so they don’t pop up over time. Next, make sure all of your vents are open and accessible for airflow. Finally, check around your house for any loose shingles and replace them as needed. It’s also important to keep an eye on weather patterns—if it looks like rain is coming soon, consider covering your roof with tarps before it starts raining so you can avoid getting wet when you remove them later on.
