A complete roof tear-off is no big deal—it’s a necessary step in protecting your roof from leaks, structural damage and long-term wear.
Whether your existing roof has reached the end of it’s life or has been damaged by severe weather, understanding the roof tear-off process and the costs involved with a roof replacement will help you make informed decisions.
Let’s go through everything you need to know before you start this major roofing project.
What is a Complete Roof Tear Off
A tear-off roof means removing all your old roofing material down to the roof deck before installing a new roof. Unlike an overlay roof where new shingles are added over the existing roofing material, a full roof tear-off gives you a fresh start so that the roofer can inspect and repair any underlying issues like moisture or structural weaknesses in the decking.
Homeowners will do a complete roof tear-off when their existing roof has multiple layers of shingles, has signs of water intrusion or needs an upgrade with new roofing material like metal or asphalt shingles.
Step by Step Roof Tear Off Process
1. Preparation and Safety
First, set up safety equipment, tarps and barriers to shield your home’s foundation and landscaping from debris. Also, it protects the gutters and other roofing materials that will be left in place.
2. Removing the Old Roofing Material
Use specialized tools like pry bars to strip away the old roofing material, shingles, underlayment and flashing. This exposes the roof deck and allows for inspection.
3. Inspecting and Repairing the Decking
Once the entire roof is exposed, the decking is checked for water intrusion, rot or structural issues. If necessary, decking replacement ensures a solid base for the new roofing material.
4. Installing Underlayment and Waterproofing
A fresh layer of underlayment is applied for better wind and moisture protection. Ice and water shields are installed in critical areas like valleys and roof penetrations.
5. Installing the New Roofing Material
Whether you’re choosing asphalt shingles, metal or other roofing material, the new roof is installed. Secure the new shingles, flashing and ventilation systems to ensure the longevity of your roof replacement.
6. Cleanup and Final Inspection
Clean the job site, and remove all debris, nails, and old roofing material. A final inspection to ensure the roof meets quality standards and looks great.
How Much Does a Complete Roof Tear Off Cost
The cost of a complete roof tear-off varies based on several factors, including roof size, material selection, labor costs and decking replacement. On average, homeowners can expect to pay between $5,000 and $15,000 for a full tear-off and roof replacement. Here’s a breakdown of the major cost contributors:
Roof Size & Complexity – A larger or steeper roof requires more labor and material, more cost.
Material Selection – Asphalt shingles are cost effective, premium options like metal or other roofing material cost more.
Decking Replacement – If the roof deck has significant damage, repairs can add $500 to $2,000 to the total.
Labor Costs – Professional installation ranges from $2 to $5 per square foot, depending on location and roofing company rates.
Disposal Fees – Old roofing material must be hauled away, dumpster rental and debris removal typically costs $300 to $1,000.
Why Choose a Roof Tear Off Instead of an Overlay Roof
While an overlay roof may seem like a way to save money, it comes with drawbacks. Adding two layers of shingles increases the weight on the home’s foundation and may hide underlying issues. A complete tear-off provides better protection, longer lifespan and better resale value.
Final Thoughts: Is a Complete Roof Tear Off Right for You
If your roof has multiple layers, extensive wear or hidden leaks, a full roof tear-off is the best investment for long term durability. While the upfront cost is higher, the benefits of a fresh, structurally sound roof far outweigh the risks of a patchwork approach.
