When a replacement is not optional

A roof-over keeps the existing deck in place with no tear-off, and on a qualifying home it is the right answer. A replacement becomes necessary when the existing roof cannot serve as a substrate for anything.

The conditions that force it:

  • Visible sag between trusses, which indicates the structure rather than the surface
  • A deck that is soft underfoot, meaning the sheathing has already failed
  • Active interior leaks that have been running long enough to reach the ceiling
  • Existing layers already in place — adding another compounds a load problem
  • A DAPIA-approved design that does not permit the added load of a roof-over [U.S. Government Publishing Office, current eCFR]

Going over any of these is not a saving. It is a deferral with interest.

What the tear-off reveals

The tear-off is the only time anyone will see the deck and the truss tops on a home that has been standing for thirty years, and it is worth treating as an inspection rather than a demolition step.

Three conditions turn up repeatedly:

Deck deterioration around penetrations. Vents, stacks and any past repair. This is where water has been entering slowly for years without ever producing an interior stain visible enough to report.

Truss-top damage from condensation. Not a leak — the roof was never breached. Warm humid interior air reached the underside of the deck through every heating season and condensed there. This is the failure mode most manufactured home roofs actually die of.

Previous repairs done as concealment. Sealant over a split panel, a patch over rot, a second layer of something laid over the first. The tear-off is where these surface, and they are almost always accompanied by damage nobody priced.

We photograph all of it and price the deck repair by the square foot actually replaced. Padding every home for damage most of them do not have is how a portfolio roof budget becomes fiction.

Ventilation gets corrected, not reproduced

Because the dominant failure mode is interior moisture rather than exterior weather, rebuilding the ventilation exactly as it was is rebuilding the thing that destroyed the roof.

Every replacement includes verifying intake and exhaust and correcting them. On a manufactured home that usually means confirming the eave intake is actually open — insulation pushed into the eave is extremely common — and that exhaust is adequate for the roof area rather than whatever was fitted at the factory in 1984.

Specified to the zone, not to a catalogue

The rebuild is specified against the HUD Wind Zone and Roof Load Zone at the home's actual location under 24 CFR § 3280.305. [U.S. Government Publishing Office, current eCFR] A home in a 40 psf northern zone gets a different assembly from an identical home in a 20 psf southern zone, and specifying nationally from one catalogue page is how the wrong roof ends up on a home in the wrong climate.

What the price covers

In the scope

  • Scope: Tear-off to deck, deck and truss inspection, repair, underlayment, new roof system
  • Deck repair: Priced as a separate line — it cannot be known before tear-off
  • Governing spec: Roof Load Zone at the home's location, per 24 CFR § 3280.305
  • Ventilation: Verified and corrected — most failures are moisture, not weather

Not in the scope

  • Anything not written in the scope. Extra work found on site is raised as a written change order before it is done.

How the job runs

  1. Walk-through

    We walk the units or the roof, or work from the walk sheet you already have.

  2. Written scope

    A written scope and price before any work starts, priced as shown above.

  3. The work

    Our own crews do it, to the written scope. Anything extra is a written change order first.

  4. Final walk-through

    We walk it again with you and close out anything on the punch list.

Step one is your scope, as it already exists.

Common questions

When the existing roof cannot serve as a substrate. Sagging between trusses, a deck that is soft underfoot, active interior leaks that have been running for a season, previous layers already in place, or a home whose DAPIA-approved design does not permit added load. In each case a roof-over is building on top of the problem.

Because nobody can know it before the tear-off. Pricing a deck repair into a bid before anyone has seen the deck means either padding every home for damage most do not have, or absorbing a loss on the ones that do. We price the tear-off and system, then the deck by the square foot actually replaced, with photographs.

Moisture from inside, more often than weather from outside. Inadequate ventilation lets warm humid air condense on the underside of the deck through every heating season. The roof looks fine from the ground while the deck quietly deteriorates, which is why ventilation is corrected on every replacement rather than rebuilt as it was.

Yes. The home was engineered for a HUD Roof Load Zone — 40 psf north, 30 middle, 20 south — and for a wind zone. The rebuild is specified against the zone the home actually sits in, which is why an identical home gets a different roof in Michigan than in south Texas.
