What goes into installing a roof on your home?

The roof is one of the most critical components of any structure, yet is often overlooked. Ensuring that your roof is in good condition to withstand anything that could potentially damage it is crucial to keeping you safe and secure. If you’re concerned about the quality of your roof, American Roofing & Waterproofing is here to help, because having a good understanding of the process will give you a better idea of what to expect. Here is the ultimate guide to installing a professional roof in 2022:

Remove the Old Roof

When replacing a roof, then the first step will always be to remove the existing roof. Neglecting to remove the old one and just simply adding new layers on top of the old ones could damage the structural integrity. It is best to remove all of the old layers and completely rebuild them. Removing the old roof is a dangerous and intricate job that should always be left to a professional roofing contractor.

Evaluate What’s Left Behind

Once the old roof has been removed, the next step is to conduct a full evaluation of what’s left behind. Oftentimes roof sheathing gets left behind and is what provides support for the new materials to be added when installing any new roof. The roof sheathing should always be inspected, and any problem areas should be repaired or replaced before going ahead with the new project.

Weather Resistance

Arizona experiences extreme heat as well as rainstorms during our monsoon season. It’s important to make sure your new roof is properly installed to prevent any damage that can come along with the high temperatures and heavy rainfall during certain months. American Roofing & Waterproofing installs a water barrier around the edges of your roof that is nailed down and adds stability and durability against strong rain or winds. This water barrier ensures your new roof will have extra protection to prevent roof leaks and further damage.

Roof Underlayment

The next step is to choose and install the roofing underlayment. There are several different kinds of roofing underlayment, each kind offering different levels of quality and durability. Some materials keep your roof deck protected against rain, snow, heat and any other unfavorable weather. The roofing underlayment is laid on the surface of your roof deck before the installation of your roofing. When your roof installation is complete, you won’t be able to see the underlayment.

Roof Shingles

What’s next? After the roofing underlayment is secured and dry, it is time to install the roofing shingles. An important step after the shingles have been installed is to paint all of the roofing pipes and vents so that they match the color of your newly installed shingles and everything blends into one.

One Last Inspection

The final step to expect from your roof installation is the final inspection. Once we’ve finished the job, we’ll do one last inspection to make sure everything is in order and to clean up any fallen debris around your yard! It’s important for us to remove any dangerous debris you or your family could step in like stray nails, sharp objects or anything that could be harmful to your family.
