The moment you realize your roof needs serious attention is usually followed by a big question: Should I repair it, re-roof it, or tear it all off and replace the entire system?
When considering a major job, homeowners in Lubbock often face the choice between two primary options: re-roofing (or “overlaying”) and a full tear-off replacement. While the cost difference may tempt you toward the cheaper option, it’s crucial to understand what you gain—and what you might lose—with each method.
At ABF Roofing, we’ve been helping West Texas families protect their homes since 2007. Here is our expert breakdown to help you make the best decision for your home and budget.
Option 1: Re-Roofing (The Overlay)
What it is: Re-roofing involves laying a new layer of asphalt shingles directly over your existing layer of shingles. It is the fastest and least expensive method to apply new material.
The Upsides of Re-Roofing:
-
Lower Upfront Cost: Because it requires significantly less labor and no disposal costs for the old material, re-roofing is generally the cheapest option.
-
Faster Completion: Without the messy, time-consuming process of a full tear-off, your new roof can be installed much faster.
-
Less Debris: The job generates very little waste, making clean-up easier and minimizing disruption around your home.
The Drawbacks of Re-Roofing:
-
Limited Lifespan: Since the existing layer likely has imperfections, the new layer may not lie flat, which can compromise its adhesion and significantly shorten its lifespan.
-
Hides Underlying Damage: You can’t inspect the wood decking (the structural foundation of your roof) for rot, moisture damage, or hail impact holes. Covering it up traps the problem inside, leading to structural integrity issues later on.
-
Added Weight: Adding a second layer of shingles doubles the stress on your home’s framing. Most municipalities allow only two layers before requiring a full tear-off for safety.
Option 2: Full Roof Replacement (The Tear-Off)
What it is: A full roof replacement involves stripping all existing materials—shingles, underlayment, and flashing—down to the bare wood roof decking (sheathing). We then install a completely new, integrated roofing system.
The Advantages of a Full Replacement:
-
Structural Inspection: This is the most crucial benefit. With the deck exposed, our ABF Roofing technicians can inspect every inch of the wood for damage and replace any compromised decking.
-
Maximum Longevity and Warranty: A new system, installed directly onto a fresh, solid surface with new underlayment, will perform optimally and typically deliver the maximum expected lifespan and warranty coverage.
-
Superior Leak Protection: A full replacement allows us to install new, continuous underlayment and flashing, creating a complete, unbroken waterproof barrier from the deck up.
-
Aesthetic Appeal: A tear-off ensures your new shingles lie perfectly flat, giving your home the clean, crisp, and high-quality finish it deserves.
The Considerations of a Full Replacement:
-
Higher Initial Cost: The process requires more labor and has higher disposal costs for the old materials, making the upfront price higher than an overlay.
-
Longer Project Time: Stripping the old materials adds time to the overall project timeline.
How to Make the Right Choice
The decision often comes down to the condition of your existing roof and your long-term goals. Here is a quick guide to help you choose the best option:
-
Choose Re-Roofing (Overlay) ONLY If:
-
The existing roof is in good, flat condition, and you are seeking the absolute lowest, shortest-term repair cost.
-
There is currently only one layer of shingles on the roof.
-
-
Choose a Full Replacement (Tear-Off) ALWAYS If:
-
The existing roof is visibly failing, warped, or has structural issues.
-
Your goal is maximum longevity, the best manufacturer warranty, and complete peace of mind.
-
You suspect any hidden leaks, wood rot, or deck damage from storms.
-
Your home already has two layers of shingles (a tear-off is required by code).
-
The roof has sustained significant hail damage, which may have compromised the wood decking beneath the existing shingles.
-
Start with an Expert Inspection
Before you decide on either option, the first and most crucial step is a professional inspection. The experts at ABF Roofing can assess your current roof for the number of existing layers, the flatness and condition of the current shingles, and any signs of decking weakness or structural rot.
We will provide you with a comprehensive, honest assessment and a free estimate so you can confidently choose the best, most cost-effective path for your Lubbock home.
