Roof Recover & Overlay in Ogden, UT

Why We Run a Moisture Scan Before Any Recover Quote

Recover and overlay roofing installs a new roof system over an existing one instead of tearing the old roof off, and it can save a building owner substantial money when the existing deck and insulation are still sound. The entire decision hinges on one question a lot of bids skip: is there trapped moisture underneath the existing roof. Recovering over wet insulation does not solve a problem. It seals it in.

Aging Industrial Roofs Around Business Depot Ogden

A large share of the older manufacturing and warehouse buildings inside Business Depot Ogden and along the surrounding I-15 corridor are reaching the point where their original roof, whether BUR, EPDM, or an early single-ply system, is aging out but the deck underneath is often still structurally sound. On buildings like these, full tear-off is not automatically the right answer, and recover can extend a roof's service life for a fraction of replacement cost, provided the existing system passes inspection first.

We also see recover requested on buildings changing ownership, where a new owner wants documented roof condition and a clear service-life estimate as part of due diligence, rather than inheriting an unknown roof history from the previous owner's maintenance records, or the lack of them.

The Moisture Survey Some Bids Skip Entirely

Trapped moisture in the insulation layer underneath an aging roof does not go away when a new membrane goes down on top of it. It keeps degrading the insulation, keeps feeding mold and deck deterioration, and eventually finds its way through the new roof anyway, usually after the warranty on the recover work has already expired. We run an infrared or capacitance moisture survey on every recover candidate before writing a proposal, and if we find wet insulation, we scope tear-off and replacement for that section specifically rather than recovering over a problem that will just resurface later, more expensively, under a brand-new membrane.

A bid that quotes a recover price without mentioning a moisture survey at all is either assuming the roof is dry or not planning to check, and neither is a safe assumption on a building that has been sitting through Weber County winters for twenty or thirty years.

Insulation Thickness and Code Requirements

Current energy code often requires additional insulation thickness beyond what an older roof originally had, which means a recover project usually needs a layer of new ISO board added on top of the existing roof before the new membrane goes down, rather than a membrane laid directly over the old one. Skipping that insulation layer to save cost cuts the R-value the building is supposed to have under current code and can create issues later if the building goes through a permit review or ownership change. We calculate the required insulation thickness for every recover project rather than assuming the existing insulation is sufficient.

We coordinate that insulation thickness calculation with the building's mechanical systems where relevant, since a taller roof assembly can change how rooftop curbs, ductwork, and equipment supports need to be extended or re-flashed, a detail that gets missed when a recover bid focuses only on the membrane layer.

What a Properly Scoped Recover Project Includes

• Full infrared or capacitance moisture survey completed before any recover proposal is written
• Wet insulation sections identified and scoped for tear-off separately from the dry recover area
• New insulation thickness calculated against current energy code, not assumed adequate from the existing roof
• Structural review confirming the roof deck can support the added weight of a new membrane layer
• Flashing and edge detail rebuilt to accommodate the new roof height where insulation is added
• Manufacturer warranty documentation specific to the recover assembly, not the original roof's warranty

When Recover Is the Wrong Call

Recover is not always the right answer, and we say so when it is not. A roof with widespread trapped moisture, significant deck deterioration, or multiple layers of previous recovers already in place is usually a tear-off candidate regardless of the short-term savings a recover quote might offer. Layering a third or fourth roof system on top of a deck that has been recovered before adds weight and complexity that outweighs the cost savings, and we will tell an owner directly when that is the situation rather than selling a recover project that is not the right long-term move.

Questions About Roof Recover and Overlay

How do I know if my roof is a good recover candidate?

We run a moisture survey and structural review first. A roof with a dry deck, sound insulation, and no more than one prior recover layer is usually a strong candidate.

What happens if you find wet insulation during the survey?

We scope tear-off and replacement for the affected section specifically, rather than covering it, and recover the remaining dry sections if that split makes sense for the building.

Does a recover project need to meet current energy code?

Yes, in most cases additional insulation is required to bring the roof assembly up to current R-value requirements, which we calculate and include in every recover proposal.

How many times can a roof be recovered before it needs full tear-off?

Most codes and manufacturer warranties limit a roof to one recover layer before requiring tear-off. Beyond that, weight and moisture risk make additional recovers a poor long-term choice.

Is recover cheaper than full tear-off and replacement?

Generally yes, often significantly, since it avoids disposal costs and reduces labor time. The savings only make sense if the existing roof passes the moisture and structural checks first.
