Mobile Home Roof-Over and Roof Coating in Edinburg

Roofing is not leveling or anchoring work, but it earns a place on this list for the same reason the vapor barrier and skirting do: anyone leveling the home is already under and around it, and a roof that has been leaking long enough eventually becomes a floor problem, which is squarely the kind of work we do. Water that gets in at a seam or a ridge cap does not stay in the ceiling. It works down into the wall cavity and eventually into the floor decking, in the same outside-wall spots where a torn vapor barrier shows up.

By the time a soft spot in the floor traces back to a roof that has been leaking for a season, the expensive repair is not the roof.

Roof-over or coating: not the same job

Getting this choice wrong costs real money, so it is worth being specific.

A coating is maintenance for a roof that has aged but not failed. An elastomeric or silicone coating goes over the existing metal, sealing every seam and exposed fastener head and adding a reflective surface. It does not fix a roof that has already given out. It protects one that has not, and on a roof with Valley heat exposure, done at the right time it is a fraction of the cost of a roof-over.

A roof-over is a replacement, not a repair. A new insulated aluminium or steel panel system goes on over the existing roof rather than tearing it off, fastened through to the structure and sealed and trimmed at every edge. That is the answer once the existing roof has widespread rust-through, seams that have opened for good, or low spots holding water after every rain. A coating over any of those traps the moisture that is already getting in rather than stopping it.

The expensive mistake is coating a roof that needed a roof-over. It looks fixed for a season, the trapped moisture finishes off metal that was already failing, and the homeowner pays for the coating and the roof-over that was always coming.

What to check before anyone quotes you

A few minutes from inside tells you most of what you need to know:

1. Ceiling panels. Soft spots, bowing between trusses, staining at a vent or panel seam, or a musty smell all point to water already past the roof.
2. Seams and fasteners from outside. Sealant that has cracked and lifted along a whole seam, or rust rings around screw heads, is failure rather than ordinary wear.
3. Standing water. Water sitting on the roof a day after rain means the roof has lost its shed and no coating fixes a shape problem.
4. Coating history. A roof already coated two or three times carries a thick, cracked buildup that will not take another coating cleanly.

Why Hidalgo County is hard on a roof

Two things work against a mobile home roof here, on two different clocks.

Sun does the slow damage. NOAA’s 1991-2020 normals for McAllen Miller International Airport put the July normal high at 98.5°F and August at 99.6°F, and Hidalgo County gets that kind of sun for most of the year. That heat bakes sealant out of seams and fastener heads for years before anyone sees a stain on a ceiling. An annual look at the roof catches this stage; waiting for a visible leak usually means a couple of summers of failing sealant already happened.

Rain does the fast damage, and it arrives in bursts. The same NOAA normals put 56 percent of the year’s 24.17 inches of rain in June through October, with September alone normaling 4.61 inches, more than any other month. Hurricane Hanna in July 2020 gusted to 60 mph in McAllen and 54 in Edinburg and left 18 inches to 4 feet of standing water east of Edinburg; Hurricane Dolly in 2008 gusted to 60 mph at Edinburg International and 71 at Weslaco Airport. Wind-driven rain in weather like that finds a weak seam immediately, and a roof with marginal sealant gets tested every hurricane season whether or not a storm actually makes landfall nearby.

Hidalgo County is HUD Wind Zone I, the standard federal wind design zone that covers all of Texas outside the coastal counties named in 24 CFR 3280.305, Cameron and Willacy among them, which start at the coast east and south of here. That does not make wind irrelevant, a Zone I system still has to be installed to its rated fastening pattern, but it is a different, lower design load than a coastal county carries, and it is worth asking any roofer what wind rating their system is installed to and getting that written into the job either way.

Licensing and permits: verified, and not verified

Texas does not license roofing contractors at the state level. The Texas Department of Licensing and Regulation does not regulate the trade, and there is no state exam, registration, or license number to check, unlike the manufactured home installer license that Chapter 1201 of the Occupations Code requires for the leveling, blocking, and anchoring work described on the rest of this site. That is not a loophole specific to us, it is simply how Texas treats roofing statewide, so the useful questions for a roofing crew are about insurance and references, not a state license.

On permits, the City of Edinburg’s Building Safety Department handles roofing permits inside city limits, and outside them the Hidalgo County Planning Department is the office to ask. We could not verify from published sources whether a roof-over specifically, as opposed to a routine reroof, triggers a permit requirement here, so call the city or county building office for their address before scheduling the work rather than guess.

Why it comes up on a leveling call

Because the underside of the home shows where the water ends up. A home with a roof that has been leaking shows it in order: wet, sagging ceiling panels, wet framing at the top of the walls, then wet floor decking, usually starting at an outside wall. That is the soft floor homeowners call about, and it is the expensive outcome, not the roof itself. When an installer is under a home for a relevel or checking the vapor barrier and finds a soft spot at an outside wall with a dry crawl space below it, the water almost always came from above, and that points back to this page rather than the underbelly.

What it costs

Roof work is quoted from the actual roof rather than a table, because size, existing condition, and trim work move the number more than a published range can honestly capture. As a starting point:

• A coating on a sound roof runs roughly $1,000 to $3,000 on a singlewide and $2,000 to $5,000 on a doublewide.
• A metal roof-over runs roughly $4,000 to $12,000, singlewide toward the lower end, doublewide with more trim work toward the top.
• Small leak and seam repairs, short of a full product, run $300 to $1,200.
• Decking or framing repair found once a roof-over starts is its own line item, priced and approved before the work continues.

The leveling, pier, and anchor pricing this business is built on stays on the published pricing page.

Tell us your home’s size, roughly how old the roof is, whether it has been coated before, and what you can see from inside. Photographs of the ceiling and of the roof surface help before anyone climbs up, and they travel with your request. Roof requests are covered across Edinburg and Hidalgo County: McAllen, Mission, Pharr, San Juan, Alamo, Donna, and Weslaco.
