Step by Step Process To Install a Roof

Here are 10 steps to installing a new roof:

Step 1 – Tear off roof & protect property

The first step in roof installation is to remove the old roof. This can be a time-consuming and messy process, so make sure your landscaping and any outdoor furniture is properly protected. Tearing off the old roof also gives you a chance to inspect and repair any damage to the roof deck.

Step 2 – Install underlayment

Underlayment is a waterproof barrier that protects your roof from water damage. It is installed before shingles, and may need to be applied in multiple layers for optimal protection. If you live in a colder climate, use ice and water shield underlayment for added protection against ice dams.

Step 3 – Install flashing

Flashing is metal strips that are installed at joints and valleys in the roof to prevent water from seeping in. Flashing should be applied before shingle installation to ensure proper placement. Or hiring a professional roofer like Metal Roofing El Paso TX to ensure proper installation.

Step 4 – Install shingles

Shingles can be installed by starting at the bottom edge of the roof and working your way up, overlapping each row as you go. Make sure to nail them securely in place and use sealant along the edges to prevent leaks. Check our guide for how to find a roof leak & tips to fix.

Step 5 – Install ridge caps

Ridge caps are shingles or metal strips that cover the peak of the roof to provide protection from water and weather damage. They can be installed by nailing them into place along the ridge, making sure to overlap and seal each piece.

Step 6 – Inspect for proper installation

Before declaring your roof installation complete, it is important to inspect for any potential issues or mistakes. Look for crooked or missing shingles, properly sealed seams, and proper installation of flashing and vents. It is also a good idea to check the attic for any signs of leaks.

Remember, taking the time to properly install felt paper and thoroughly inspect your roof can save you from costly repairs in the future.

Step 7: Cover the roof with felt paper.

Felt paper acts as a protective barrier between the roof deck and the shingles. It helps to prevent moisture damage and adds an extra layer of defense against leaks.

It is important to properly overlap each piece of felt paper by at least 2 inches and secure it with roofing nails. Properly installing felt paper can greatly extend the lifespan of a roof. 

It is also important to use the appropriate weight of felt paper for the type of shingles being used – for example, using heavy duty felt paper with lightweight shingles can cause damage to the shingles. 

Consult with a roofing professional or reference manufacturer guidelines to ensure proper selection and installation of felt paper.

Step 8: Waterproof seams and flashing.

To ensure a waterproof seal, it is important to apply roofing cement or plastic roofing cement to all seams, flashings, and nail heads. This helps to prevent leaks and potential water damage. 

Step 9: Install vents and pipes.

Vents help improve air circulation in the attic and prevent moisture buildup, while pipes allow for proper drainage. Properly installing vents and pipes helps to prevent damage to the roof and attic.

Step 10: Clean up and remove debris.

After the roof installation is complete, it is important to clean up any stray nails or debris that may have fallen during the installation process. This will help prevent accidents and potential damage to cars, landscaping, or outdoor furniture. And also help improve the overall appearance of the roof.


Some common roof installation problems include incorrect measurements, improper flashing installation, and inadequate ventilation. These issues can be avoided by hiring a reputable and experienced contractor, thoroughly inspecting the materials before installation, and properly maintaining the roof after it has been installed.

To install a roof of an average residence (3,000 square feet or less) it can take a professional roofing crew anywhere from 24-48 hours to complete. This time frame may vary depending on the complexity of the roof and weather conditions.

You should not stay in the house during roof installation. It is safest to leave the premises while the professionals do their work. There may be falling debris or other safety hazards present during the installation process. It is best to leave the house until the job is finished and it is deemed safe for re-entry.
