Reading an Older Roof Layer by Layer
A roof that looks like a single membrane from above may sit on top of an older gravel-surfaced built-up roof and one or two layers of insulation. We take small test cuts in representative areas to see the layers, check whether insulation is wet, and look at the condition of the deck. That information drives every recommendation that follows and keeps surprises out of the final bill.
Tear-Off or Recover?
A roof recover places a new system over the existing roof and can save on removal and disposal. It only makes sense when:
- The existing roof and insulation are dry
- The deck is sound and can carry the added weight
- Codes allow another layer over what is there
If any of those fail, a full tear-off is the right call. Trapping wet insulation under a new membrane shortens its life and can lead to deck rot.
Repairing Built-Up and Modified Roofs
Not every older roof needs replacing right away. Blistered or split built-up roofs, failed base flashings and open laps can often be repaired with compatible asphalt-based materials. We tell you how much life a repair is likely to buy so you can plan the bigger project with real numbers. For a general look at repair options on low-slope roofs, see our flat roof repair guide.
Replacing a Roof on an Occupied Building
Offices, clinics and shops in Jackson usually stay open during a re-roof. We phase tear-off so only what can be dried in that day is opened, protect interiors below work areas, manage debris chutes and dumpsters away from entries, and keep tenants informed. Final walkthroughs include photos of key details such as drains, edges and penetrations. If your building took a hit from wind or hail, our Jackson storm damage roofing page explains how we document it.
Common Questions
How can I tell if my roof insulation is wet?
Soft or spongy spots underfoot, persistent interior stains and blistering are common clues. Test cuts confirm it. We check suspect areas during our inspection.
Is a recover always cheaper than a tear-off?
It usually costs less upfront, but only when conditions allow. A recover over wet materials can cost more in the long run because the new roof fails early.
Do you handle storm damage on commercial roofs in Jackson?
Yes. We document wind and hail damage, provide temporary repairs and can meet with your adjuster. See our Jackson-area storm roofing information for more detail.
Are your estimates free?
Yes. Initial commercial roof inspections and estimates are free.
