Roof Installation Process

Roof Installation Process

After completing the tear-off process, our experienced roofers will inspect the decking of your roof for any damage. Soft spots or damage in the sheathing are indicators that it needs to be replaced with a new one, however before the sheathing can be cut into, our contractors check for any wiring underneath it in order to avoid accidentally cutting your telephone or TV cables. If there is damage in your roof’s sheathing, the reason is probably the violation of the roof seal, which tends to occur around skylights, chimneys, roof vents, etc. Step by step process:
  • Our contractors cut the damaged area next to the rafters.
  • They then nail wooden strips to the rafters’ edges.
  • Exterior grade plywood is used during the replacement, and 1/8 of an inch is reserved for possible expansion on all sides.

Installing Roofing Underlayment

You should take extra caution in ensuring that your contractor uses an under layer of felt paper, also known as building paper. Most roofing companies in Toronto use this technique, as it provides extra protection against leakage and damage. Royal Roofing Inc also installs an additional protective layer called the “ice and water shield” or “ice guard”, which is very beneficial for a city with a cold and unpredictable climate like Toronto. The ice and water shield is used in valleys, along the eaves, and rake edges of the roof in order to ensure the highest possible level of protection. Some companies in the GTA avoid using this method to save money, so you need to ensure that the ice and water shield is included in your estimate. Avoid dealing with companies, who refuse to provide the shield, and keep in mind that Royal Roofing Inc is always at your service. Step by step process:
  • A chalk line is used to represent the surface along which the shield is to be installed.
  • Felt paper is applied and customized to perfectly fit the specifics of your roof.
  • An extra drip edge is installed along the rake edge of your roof to protect your house from blowing rain.


The seams around roof elements and adjoining surfaces need to be protected, which is why a metal of a rubber barrier needs to be installed in a process called flashing. The purpose of this is to lead the water off the roof and keep it away from the seams, which means that flashing is usually installed in areas, where shingles are prone to leaks or cannot be applied at all. This is why flashing, in most cases needs to be made custom for every roof. Sometimes the repairs you require on your roof may include changing or installing additional flashing for extra protection. Aluminum, galvanized steel, or copper are the materials that usually make up metal flashings, which are an important component in ensuring the longevity of your roof’s life. Step by step process:
  • Our contactors use your old flashings as a template for new pieces.
  • New flashing is then installed wherever necessary on the roof.
  • Then the installation is made in the valley, to ensure that the water is guided off the roof.

Installing Roof Shingles

Most homeowners in Toronto, as well as the rest of Canada, prefer to use asphalt shingles (also called composition shingles for their roof. This is based both on their performance and appearance. Not only do asphalt shingles serve homeowners well in all types of climates, but are also available in a variety of colors, textures, shapes, and can complement the design of any house. Moreover, asphalt shingles are the cheapest to repair and are very durable. The most common shingle type is the three-tab, as it is visually appealing, durable, and very affordable. Step by step process:
  • Felt paper is laid down prior to the installation of shingles.
  • Shingles are then staggered to ensure superior protection against leaks.
  • Shingles begin to be installed starting from the bottom of the roof.
  • Shingles then continue to be installed in layers in accordance with the measurements. (sometimes shingles need to be cut and customized to fit certain areas of the roof)
