Installing a new roof is a significant investment that enhances the structural integrity and aesthetic appeal of your home. Professionals follow a meticulous process to ensure a durable and aesthetically pleasing roof installation. Here’s a detailed breakdown of how Niagara roofing experts accomplish this task, from removing the old roof to installing the new one.

Inspection and Preparation

Before beginning the installation process, professionals conduct a thorough inspection of the existing roof to assess its condition and identify any underlying issues. This inspection helps them determine the appropriate course of action and materials needed for the project. Once the inspection is complete, they prepare the site by clearing debris and ensuring the work area is safe and accessible.

Removal of the Old Roof

The first step in installing a new roof is removing the old one. Professionals use specialized tools such as shingle removers, pry bars, and roofing knives to carefully strip away the existing roofing materials. They work systematically, starting from the top and working their way down to ensure all layers are removed completely.

Inspection of the Roof Deck

After removing the old roof, professionals inspect the underlying roof deck for any signs of damage, rot, or deterioration. Any issues found are addressed promptly to ensure a solid foundation for the new roof.

Installation of Underlayment

Once the roof deck is inspected and repaired as needed, professionals install a waterproof underlayment to provide an additional layer of protection against moisture infiltration. This underlayment acts as a barrier between the roof deck and the shingles, helping to prevent leaks and prolong the life of the roof.

Installation of Drip Edge and Flashing

Next, professionals install drip edging along the edges of the roof to redirect water away from the fascia and prevent moisture damage. They also install flashing around roof penetrations such as chimneys, vents, and skylights to create a watertight seal and prevent leaks.

Application of Roofing Materials

With the preparatory work complete, professionals begin installing the roofing materials. Depending on the chosen roofing system, this may involve laying down asphalt shingles, wood shakes, metal panels, or other roofing materials. They follow manufacturer guidelines and industry best practices to ensure proper installation and optimal performance.

Ridge Vent Installation

To ensure proper ventilation and airflow in the attic space, professionals install ridge vents along the peak of the roof. These vents help regulate temperature and moisture levels, reducing the risk of mold growth and prolonging the life of the roof.

Final Inspection and Cleanup

Once the new roof is installed, professionals conduct a final inspection to ensure everything is in order and meets quality standards. They check for any loose shingles, gaps in flashing, or other issues that may compromise the integrity of the roof. Once satisfied with the results, they clean up the work site, removing debris and leftover materials to leave your property clean and tidy.


Installing a new roof is a complex process that requires skill, experience, and attention to detail. By following these steps and entrusting the job to trained experts, you can ensure a successful roof installation that provides lasting protection and enhances the beauty of your home.
