Understanding Roof Removal and Waste Disposal

When it’s time for a new roof, most Portland homeowners focus on the fun stuff—shingle colors, warranties, or the final look. But have you ever wondered what happens to your old roof? At Hawthorne General Construction, we know that tear-off and disposal are critical steps in any quality roof replacement. Let’s break down what really happens when your old roof comes off—and why this step matters more than you might think.

What Is Roof Tear-Off?

Tear-off is the process of removing your old roofing system—shingles, underlayment, nails, flashing—down to the bare roof decking. It’s a vital step that gives us a clear look at the structural condition of your roof before we install anything new.

Skipping tear-off and installing new shingles over the old ones (called a roof overlay) can hide serious problems and shorten the life of your new roof—especially here in Portland’s wet, moss-prone climate.

Why Tear-Off Matters in Portland

Here in Portland, we deal with:

• Heavy rain

• Moss buildup

• Hidden moisture damage

Without removing the old roof, there’s no way to properly inspect the roof deck (the wood sheathing beneath your shingles). Tear-off allows us to identify and repair:

• Rotten or moldy decking

• Water intrusion

• Structural damage from years of weather exposure

These issues are more common than you might think—and they’re exactly why we always recommend full tear-off before installing a new roof.

How Tear-Off Works

When you hire Hawthorne General Construction, here’s what happens during the tear-off process:

1. Property Protection

   • We use tarps, plywood, and protective barriers to shield your siding, landscaping, and windows.

2. Shingle & Underlayment Removal

   • We carefully remove all roofing materials, including nails, flashing, vents, and old waterproofing layers.

3. Decking Inspection

   • Once the roof is stripped, we inspect every square foot of decking. If any plywood is damaged, we replace it.

4. Clean-Up as We Go

   • We collect debris as we work, keeping your property as tidy as possible.

What Happens to All the Debris?

You might be surprised at how much material comes off during a tear-off. But don’t worry—we handle it all:

• On-Site Dumpsters or Trailers
  We bring our own containers to haul away debris quickly and safely.

• Recycling Whenever Possible
  Some materials, like asphalt shingles or metal flashing, can be recycled. We dispose of materials in eco-conscious ways aligned with Portland’s green initiatives.

• Magnetic Nail Sweeps
  After tear-off, we use industrial magnets to sweep your yard and driveway, collecting any stray nails or metal scraps.

• Final Cleanup
  Before we leave, your property is spotless—no mess left behind.

Avoiding the Overlay Shortcut

Some roofers might try to sell you on a roof overlay to save money. We don’t recommend it. Why?

• It adds extra weight to your roof structure

• It hides leaks and rot

• It may void your manufacturer’s warranty

• It doesn’t last as long as a full replacement

In a wet climate like Portland’s, those risks simply aren’t worth it.

Is Tear-Off Included in the Estimate? It Should Be.

A trustworthy roofing company will include tear-off and disposal in your initial estimate—not as a surprise fee later.

At Hawthorne General Construction, every full roof replacement includes:

• Complete tear-off

• Deck inspection

• Debris removal and cleanup

• Transparent pricing—no hidden fees

Protect Your Investment by Doing It Right the First Time

Your roof protects everything under it. Skipping steps or cutting corners can lead to expensive damage down the road.

At Hawthorne General Construction, we believe in doing things the right way—starting with a clean foundation and ending with a clean yard.
