Step by Step Roofing Instructions

Roofing a house is not a simple task. There are different elements involved, from the materials down to the measurements, and the actual roof installation process.

Follow the guide below to find out what happens in a roofing installation process.

Old Roof Removal

For properties that require a total roof replacement, the first step is to remove all the parts. This is done to give way for new roofing materials. However, there’s an option to tear-off the roof to remove only the damaged and ineffective elements. The goal is to save some areas that are still in good condition. In the first stage, the roofer should clear the surface as a preparation for the new construction.

After making sure that the old and damaged parts of the roof are removed, the roofers can now proceed to the sheathing evaluation. These are the flat panels that provide structural support for the roofing materials. It acts as a base for the new roofing system, hence, it should be in good condition. If there are too many moist areas and damages, then, the roof sheathing should also be replaced.

Ice and Water Barrier

In most parts of Canada including Calgary AB, snow is a common sight. For areas that are prone to ice almost all year round, there’s a need to install an ice and water barrier. This protective element will help defend the roof against water damages caused by ice. The roofing contractor will install this on the edges of your roof to lessen the chances of ice buildup. The underlayment is attached to the roof sheathing to secure it in place.

Drip Edge

After the previous steps, the roofer will now move on to the drip edge. You need a drip edge to prevent water from spilling over the edges down to the siding and underneath it. It helps lead water in the right direction.

Normally, it will be installed at the bottom edges of the roofing structure. They will position it on top of the ice and water barrier, then nailing it for stability.


Usually, there are two types of roof underlayment. One is made from felt paper and the other one is synthetic. They both come in varying thickness and are saturated in water-resistant chemicals. To know what kind of roofing underlayment you need, consult professional roofers. Deciding for yourself might result in negative consequences or might compromise the integrity of the whole structure.

The roofing underlayment is secured in place by hammering roof nails along the edges and in the center of the surface. The underlayment sections should also be overlapping until they reach the peak of the roof.

Installation of Roofing Materials

Even before the installation begins, there are elements that should be decided on. These include the type of roofing system that you would suit your property. There’s a wide range of options to consider. For instance, you can choose from the traditional roofing materials such as wood, tiles, asphalt, metal, etc. You may also want to explore synthetic roofing systems like EPDM (rubber) or PVC.

Out of all the options that you have, what should you select? The screening process should be a collaboration between you and your trusted roofing contractor. You should look into budget implications, durability, longevity, performance, and of course, the outer appearance. That would include the design, finish, color, style, among others. You should also be aware of the downsides of the material that you want in order to prepare for the coming years.

When you’ve finally reached a decision, the roofing contractor will take care of the installation process. Each material requires a specific process. For asphalt shingles, they have to layout and attach the pieces one by one. There’s a need to make sure that the alignment is accurate so that the outcome would look presentable.


After the materials are carefully attached on the surface, the last step would be clearing. The roofers should ensure that no mess will be left behind. This is still a crucial part of the roof installation process because if the area wasn’t cleaned properly, any lying debris, tools, materials, etc. may trigger accidents or may damage the roof.

Now that you’re already aware of what should take place in a roof installation process, you may be asking why should you get a new roof? Well, aside from the most common reasons why (which are emergency roof replacements due to natural calamities), what else to look out for?

Persistent Leakage

If leaks have been a constant headache in your house, then you might be a candidate for a new roof installation. Water damages can contribute to deterioration shortening the lifespan of your roof. While there are water issues that you can temporarily fix, they can still snowball and result in more serious problems in the near future. If you’re dealing with leaks over and over again, better call an expert the soonest to detect the larger unseen issues.

Sagging Roof

A misaligned or sagging roof is a downright emergency situation. It can lead to accidents and could also compromise the integrity of the foundation. If you notice that your roof looks odd maybe because of its alignment, contact a trusted local roofer for an immediate inspection.

The roof should always be intact. If you notice natural light penetrating through the ceiling, then there may be underlying issues that point to a new roof installation.
