At Integrity Home Exteriors, we've been replacing roofs for over 25 years. During that time, we've seen what works and what doesn't. When it comes to getting a new roof, there are two main options: a complete tear-off or an overlay. This article explains what a roof tear-off is, why it matters, and why professional roofers like us always recommend it.


What Exactly Is a Roof Tear-Off?

A roof tear-off means removing all the old roofing materials down to the wooden deck below. Think of it as starting fresh with a clean slate. We take off everything – old shingles, felt paper, flashing, and even nails – before putting on new materials.

This is different from an overlay, where new shingles are installed right on top of the old ones. Here's how they compare:

Five Clear Signs Your Roof Needs a Tear-Off

How do you know if your roof needs a complete tear-off? Look for these signs:

1. Your Roof Already Has Two Layers

Most building codes only allow two layers of roofing. If you already have two layers, you legally must do a tear-off for your next roof.

2. Your Shingles Are Curling or Buckling

When shingles start to curl at the edges or bubble in the middle, it's a sign they're worn out and need to be removed.

3. You Find Granules in Your Gutters

Asphalt shingles shed their protective granules when they age. If you see a lot of small granules in your gutters, your shingles are wearing out.

4. Your Roof Is Leaking in Multiple Places

One small leak might be fixable, but multiple leaks often mean it's time for a complete tear-off.

5. Your Roof Is More Than 20 Years Old

Even if it looks okay from the ground, a roof that's over 20 years old is near the end of its life and is a good candidate for a tear-off.

Quick Checklist: Do a tear-off if:

  • Your roof is over 20 years old

  • You already have two layers of shingles

  • You can see visible damage from the ground

  • You have multiple leaks

  • Your energy bills have been rising (poor roof performance)


Why Pros Always Choose Tear-Offs (The Benefits)

There are good reasons why professional roofers recommend tear-offs:

Finds Hidden Problems

We can see and fix rot, water damage, or soft spots in your roof deck. These problems stay hidden with an overlay and get worse over time.

Lasts Longer

A new roof on a clean, solid base typically lasts 20-30 years. An overlay might only last 15-16 years. That's up to 10 extra years of protection!

Saves Money Long-Term

While tear-offs cost more upfront, they save money in the long run. You avoid costly repairs from hidden damage and delay replacement longer.

Follows Building Codes

Most local building codes only allow a maximum of two roofing layers. A tear-off keeps your home up to code and avoids problems when selling.

Adds Home Value

Realtors estimate a proper tear-off and new roof can add over $10,000 to your home's value. Buyers know they won't need to replace the roof soon.


The Tear-Off Process: How It's Done (Simple Steps)

Here's what happens during a professional roof tear-off:

1. Preparation

The team sets up protection for your landscaping, siding, and windows. They bring in a dumpster for the old materials and make sure safety equipment is in place.

2. Removing Old Materials

Starting at the peak of the roof, workers remove all shingles, felt paper, flashing, and nails. They work in sections, carefully taking everything down to the wooden deck.

3. Inspecting the Roof Deck

Once the old materials are gone, the team checks every inch of the wooden deck. They look for rot, water damage, soft spots, or warping. Any bad sections get replaced with new wood.

4. Installing New Materials

After repairs, new water-resistant underlayment goes down first. Then comes proper flashing around chimneys and vents, followed by new shingles.

5. Cleanup

When the new roof is complete, the team does a thorough cleanup. They use special magnets to pick up nails and make sure your yard and driveway are free of debris.

Common Questions About Roof Tear-Offs

How long does a roof tear-off take?

For most homes, a complete tear-off and new roof is finished in one day. Our experienced crews work efficiently to remove your old roof and install the new one all in the same day.

Does a tear-off cost a lot more than an overlay?

A tear-off typically costs about 10% more than an overlay. The small extra cost upfront saves you money in the long run by lasting years longer and preventing expensive hidden damage. Understanding roof replacement costs helps you make an informed decision.

What happens if it rains during my tear-off?

Professional roofers check weather forecasts carefully. Since we complete most tear-offs and installations in one day, weather delays are rare. If unexpected rain comes, we use heavy-duty tarps to protect your home.

Will a tear-off be noisy and messy?

Yes, there will be noise during working hours. We do our best to contain the mess with tarps and do thorough cleanup every day, including using magnetic sweepers to find nails.

Can I stay in my home during a tear-off?

Absolutely! Most families stay in their homes during the process. The work happens on the outside of your house during daytime hours.

How do I know if I already have two layers of shingles?

Look at the edges of your roof where it meets the gutter. If you can see two distinct layers of shingles, you already have an overlay. A professional can tell for sure during an inspection.

Will a tear-off fix my leaky roof?

Yes, a tear-off addresses the source of leaks by removing all old materials and letting us find and fix damage in the wood beneath. This gives you a truly watertight roof. For immediate leak issues, we also provide roof repair services.
