Is your roof beyond simple repairs? This typically happens when there’s widespread damage or the roof is nearing the end of its lifespan. Frequent leaks, structural problems, and reduced energy efficiency are clear signs you need a new roof.

Re-roofing your roof comes with several benefits. Apart from being more durable and less prone to leaks, a new roof can boost your property's resale value. In 2023, the ROI for a new asphalt roof was  61.1%

Now, you might be wondering, how do you replace a roof?

Good question! Understanding each step of roof replacement helps you know what you're paying for. You can also leverage this information to have more transparent conversations with your roofing contractor.

As leading Reno roofing experts, we're here to guide you through this big decision. Let's dive in!


Good preparation sets the stage for a smooth replacement roofing project. Usually, it involves:

  • Choosing a Contractor: The first step is to find the right contractor. Look for a reputable, licensed, and insured roofing expert. Don't just settle for the first one you see. Compare roofing professionals to get the best value for your money. 
  • The Inspection: The roofing contractor will assess your roof for damage, age, and other issues like weak spots or poor insulation. The idea is to take precise measurements and figure out what's needed for your new roof. 
  • The Contract: After the inspection, your contractor will give a bid based on your roof's measurements and chosen materials. Once you accept this quote, they'll present you with a written contract.  

Read the contract carefully before signing. It should clearly state the work scope, materials, timeline, and cost. Clarify any doubts in advance to minimize conflicts down the line. 

A reputable roofing contractor will also secure the necessary permits to comply with local building codes. You don't want to put up a new roof and discover the material type isn't allowed in your area.

The Roof Replacement Process

Your roofing materials will arrive on the day of or a couple of days before the roof replacement begins. But we recommend not having roofing material delivered too early to avoid damage to your lawn.

On the big day, your contractors will first secure your property to prevent damage during the replacement. They'll set up measures to protect your home's exterior, landscaping, and surrounding areas from dirt and debris.

Then, they will:

Tear Off Your Old Roof

First off, the contractors will tear down the old roof. New shingles need a clean, flat surface to stick properly and last longer. There's going to be a bit of noise and mess, so be prepared!

Taking down an existing roof creates a ton of waste, so it's important to have a proper disposal method in place. A reputable replacement roofing contractor will follow local regulations and environmental guidelines to dump the waste responsibly.

Check the Underlayment and Sheathing

Next, your roofer will shift focus to the underlayment and sheathing. The underlayment sits between the roof deck and asphalt shingles, providing a waterproof or water-resistant barrier to keep the roof dry. 

On the other hand, sheathing forms the structural base for the roofing materials. It's made of panels that attach directly to the roof trusses or rafters to create a flat surface for the shingles. 

Moisture, mold, and rot can weaken the sheathing over time. Hence, it's crucial to check and fix any damage to these layers before putting on a new roof. Repairing or replacing sheathing ensures your entire roof is strong, water-resistant, and ready to protect your home for years to come.

Install the New Roof

Now comes the thrilling part: installing the full roof replacement. Whether you've chosen classic shingles, sleek metal roofing, or another type, your contractor will install each part with skill and precision. They know exactly how to handle the materials you've picked.

You should also consider adding more vents if your previous roof lacked adequate ventilation. Proper ventilation can prevent mold and increase energy efficiency by regulating your attic's temperature/moisture levels.

Replace the Flashing

Our clients often ask us if they should replace their flashing when getting a new roof.

The answer is yes. 

Even if your flashing seems in good shape, it's best to replace it with your roof. Typically, flashing lasts as long as the roof does with proper installation. So, while it might look okay now, its lifespan is likely limited to just a few more years.

Completion and Post-Replacement

That's it! Your new roofing in Reno, NV, is up and ready for action. But there's still some work to be done.

1. Cleanup and Removal

After the roofing installation, the crew will clean up after themselves. They'll pick up their tools, sweep away debris, and haul away the old roofing materials to leave your property spick and span.

2. Final Inspection

Your roofing contractor will inspect the new roof one last time to check if everything is up to code. Join in and see if:

  • The shingles look even 
  • The flashing around the chimneys and vents is tight and sealed 
  • The gutters and downspouts are properly attached

If you spot anything odd or have questions, ask your contractor right away. This is your last chance to make sure everything is done right!

3. Warranties and Guarantees

Understand the warranties your contractor and the roofing material manufacturer offer. These cover the quality of work and the materials used. Knowing what's covered will help you if there are any issues with your new roof in the future.
