Your roof won’t last forever, but it shouldn’t keep you up at night, either.
Depending on the issues that arise from a roof inspection, you might receive a recommendation for a larger installation project.
Not only are these time-consuming projects that can have some impact on business operations, but it could also be a heavy capital expense you weren’t planning for.
In the short term, re-roofing – which refers to adding an additional layer to your existing roof – is the cost-effective option. Depending on the age and condition of your roof, it’s an effective solution to extend its lifespan, while extending the time you have to budget for a full replacement.
But if you’re experiencing widespread leaks or structural damage, or if it’s been several decades since you last had a roof replacement, it’s time to make a plan of action to get that new roof installed.
If you’re weighing a re-roof (recover) against a full tear-off replacement, here’s a clear guide to help you choose the smartest path for your building, your budget, and your long-term plans.
What Exactly Is a Re-roof?
A re-roof (or roof recover) is the roofing world’s version of a fresh topcoat:
- Scope: Install one new waterproof layer over the existing system No tear-off, no exposed deck.
- Lifespan added: 8–15 years, depending on membrane and maintenance.
- Best-fit situations: Dry, well-adhered roofs with minor wear, and owners looking for a budget-friendly bridge before a major cap-ex cycle.
What Counts as a Full Roof Replacement?
Think of a full replacement as a factory reset:
- Scope: Strip every layer down to the structural deck, repair or replace damaged decking, rebuild with brand-new insulation, membrane, and edge metal.
- Lifespan added: 20–30 years with today’s single-ply and multi-ply assemblies.
- Best-fit situations: Widespread leaks, trapped moisture, structural damage, or plans for rooftop solar/HVAC that demand a blank slate.
Decision Filters for Roof Recover vs. Roof Replacement
Beyond age and lifespan considerations, here’s what you should be looking at:
- Moisture & Insulation Health
Core cuts or infrared scans can tell you if insulation is saturated. If more than 25 percent is wet, replacement is the sounder choice. Installing new membrane over wet insulation only buries the problem.
- Energy-Code Targets
Need to jump from R-15 to R-30 or higher to meet current energy codes? A roof recover can’t add much insulation without creating awkward flashing heights. Tear-off replacement lets you build the new R-value into the system, pursue rebates, and reduce HVAC loads for years – even decades – to come.
- Structural Weight & Snow Load
Buffalo roofs already carry serious snow weight. Each extra roofing layer extra weight, more if you have a built-up roof rather than modified bitumen. If you’re approaching structural limits, a re-roof might push you over.
- Business Disruption
- Recover: Quiet, low-odor, minimal dumpsters, and it’s often completed while the building stays in full use.
- Replacement: Expect cranes, tear-off noise, and coordinated material drops. With Grove Roofing’s in-house hoisting and tight scheduling, we keep docks clear and shifts running, but the disruption window is still larger.
- Lifetime Cost of Ownership
Re-roofs will always be a lower present-day cost; replacements will win on 30-year net present value. Find a roofing partner who can help you understand these considerations and help your finance team see the full picture.
