Mobile Home Roofing: Replacement, Coating, and 2026 Cost Options

By The Roofing Brief Team. Last reviewed: October 2026.

The main mobile home roofing options are a liquid coating, a new membrane or shingle roof, a metal roof, or a roof-over installed on top of the old roof, and HomeGuide’s 2026 mobile home roof cost guide prices them at $0.50 to $4.50 per square foot for coating, $3 to $5 for shingles, $4 to $10 for TPO or EPDM rubber and $5 to $16 for metal, installed. A full mobile home roof replacement runs $1,500 to $9,600 for a single-wide and $3,000 to $16,000 for a double-wide in the same guide, while a roof-over costs $1,000 to $4,500. Which option fits depends on three facts you can check today: the roof slope (shingles need at least 2:12 under IRC R905.2.2), the wind zone and roof load zone printed on the home’s HUD data plate (24 CFR 3280.5), and how many years you plan to keep the home.

Short answer: the three paths and which to pick

A mobile home roof is not a regular roof. The structure is lighter, often a metal roof skin over light trusses instead of dimensional lumber and sheathing, and HUD code 24 CFR 3280.305 sizes it for a roof live load of only 20, 30 or 40 psf depending on the roof load zone. The original roofing is usually one of three things: rolled asphalt, low-slope metal, or asphalt shingles on a peaked roof. Each existing condition opens a different path, and the slope decides which coverings are legal: shingles need 2:12 or steeper (IRC R905.2.2), while TPO, EPDM and modified bitumen are designed for slopes down to 1/4:12.

Three questions pick the path. How many years will you own the home, compared with HomeGuide’s 30 to 50 year typical life for a mobile home? Is the slope under or over 2:12? And does the data plate show the roof load zone and wind zone your new material and fasteners must meet? If you plan to sell within 3 years, a coating at $0.50 to $4.50 per sq ft usually solves the inspection issue; if you plan to own for 10 or more years, a membrane or metal roof spreads the cost over 15 to 80 years of HomeGuide’s lifespan ranges.

Which mobile home roofing option fits your roof?

Mobile home roof types: peaked vs. flat (low-slope)

Manufactured housing roof construction falls into two structural categories: “peaked” (also called “sloped” or “pitched”) and “flat” (also called “low-slope” or “minimal-slope”). The dividing line for roofing purposes is 2:12, the minimum slope for asphalt shingles in IRC R905.2.2.

Peaked mobile home roofs have a recognizable ridge running the length of the home, with trusses sloping down to the eaves on both sides. The HUD wind pressure table in 24 CFR 3280.305 applies to roof slopes between 10 degrees (nominal 2/12) and 30 degrees, which brackets most peaked manufactured home roofs. The structure is closer to a conventional roof: trusses, sheathing, underlayment and asphalt shingles, and footnote 6 of that table lets shingles secured with 6 fasteners per shingle through cemented underlayment on 3/8 inch structural sheathing skip separate wind-pressure evaluation. These roofs accept conventional reroof materials that meet the slope minimums in IRC R905.

Flat (low-slope) mobile home roofs are common on older homes and on park-model units, typically below 2:12. The original roofing material is usually rolled asphalt, metal sheets bonded with seam sealant, or a single-ply membrane, and 24 CFR 3280.305 allows one-piece metal roofing without structural sheathing when it passes HUD-approved wind testing. Reroof options are limited to low-slope materials: rolled roofing (1:12 minimum under IRC R905.5.2), modified bitumen, EPDM, TPO, or coating systems. Shingles are not an option below 2:12 without building a new sloped frame, which HomeGuide prices at $6 to $15 per square foot for the framing alone.

Identify your roof type before pricing options. A peaked roof on a 1995 double-wide at 3:12 can take shingles with double underlayment; a flat metal roof on a 1978 single-wide at under 1:12 cannot take shingles or rolled roofing without new framing.

HUD code 24 CFR 3280: what governs mobile home roof work

The Manufactured Home Construction and Safety Standards (24 CFR 3280) apply to manufactured homes built on or after June 15, 1976. The roof-relevant sections:

• 3280.305, structural design requirements: roof live load of 20 psf (South zone), 30 psf (Middle) or 40 psf (North), Wind Zone I design for 15 psf horizontal and 9 psf net uplift, and design wind speeds of 100 mph (Zone II) and 110 mph (Zone III).
• 3280.307, resistance to elements and use: under the Manufactured Home Construction and Safety Standards, exterior coverings must be moisture and weather resistant, attached with corrosion resistant fasteners, with joints sealed against air and water.
• 3280.401 and 3280.402, structural load tests: the factory test procedures, including roof trusses, that document what the roof structure can carry.
• 3280.5, data plate: lists the roof load zone and wind zone the home was designed for, with copies of both maps.

The practical impact for a homeowner doing a reroof or coating: any modification that adds dead load (heavy tile, added framing, a second roof layer) uses up part of a roof designed for as little as 20 psf of live load in the South zone. A coating adds very little weight; a peaked roof-over adds framing, which is why kit makers supply engineering for specific home sizes and zones. Compare the added weight in the product data with the roof load zone on your data plate before you buy.

Most mobile home roof replacements stay within the original design loads when the old material comes off before the new goes on. Layering shingles over shingles adds a full second layer of dead load to a roof that may be designed for only 20 psf of live load, so treat it as off the table on a manufactured home unless an engineer signs off against the data plate roof load.

Wind zone matters too. Under 24 CFR 3280.305(c), Wind Zone I covers most of the inland United States and is designed for 15 psf horizontal and 9 psf uplift; Wind Zone II (100 mph) covers listed coastal counties such as Baldwin and Mobile in Alabama and most of Florida; Wind Zone III (110 mph) covers Hawaii, coastal Alaska, U.S. territories and listed counties such as Broward, Dade, Lee and Palm Beach in Florida. The data plate rule places the plate near the main electrical panel or another readily accessible spot, and it lists your zone. Reroof materials and fastening must match.

Roof coating path: elastomeric and silicone systems

Elastomeric and silicone roof coatings are liquid-applied systems that bond to an existing roof surface and form a continuous waterproof layer with no joints. HomeGuide prices them at $0.50 to $4.50 per square foot, the lowest-cost path for a leaking or aging flat mobile home roof, and they are the most common DIY mobile home roof repair project.

The product categories:

• Asphalt-based coatings (aluminum roof coating, fibered aluminum, fibered asphalt). The budget patch layer; they leave a dark or metallic surface that a white topcoat such as Henry 287 needs a bleed-blocking primer to cover.
• Acrylic elastomeric. Example: Henry 287 Solar-Flex, applied at 2.0 to 2.5 gallons per 100 sq ft in two coats, at 50 degrees F and rising, with no rain, fog or sub-50 F temperatures expected for 48 to 72 hours. Henry’s data sheet rules it out for areas with ponding water and over rubber or PVC sheet roofing. See elastomeric roof coating for the full product breakdown.
• Silicone roof coating. Example: Henry 887 Tropi-Cool, one coat at a minimum of 1.5 gallons per 100 sq ft (22 mils dry), rain-safe in 15 minutes, CRRC solar reflectance 0.88 initial and 0.73 aged, lifetime limited warranty. See silicone roof coating.
• Urethane and polyurea. Specialty systems installed by applicators.

Material quantity follows the data sheet rate and the roof area. A 12 by 60 single-wide has about 720 sq ft of roof before overhangs; a 28 by 60 double-wide about 1,680 sq ft. The worked example below uses the two Henry products named above.

For pro install, HomeGuide’s 2026 range is $0.50 to $4.50 per sq ft, putting the same 720 sq ft single-wide at $360 to $3,240, and its whole-home range is $250 to $5,400 for single-wides and $500 to $9,000 for double-wides.

The coating process:

1. Power wash or stiff-broom the existing roof. Henry’s 887 instructions call for treating algae or moss with a 50:50 mix of laundry-strength bleach and water, left to dwell 15 to 20 minutes, then rinsing with low pressure water and letting the roof dry completely.
2. Repair any visible damage. Patch holes and open seams with seam tape and a compatible roof sealant.
3. On metal roofs, remove rust by wire brushing, as the Henry 887 data sheet specifies, and treat remaining rust with a rust-converting primer.
4. Apply bleed-blocking primer if recoating over asphalt-based products (prevents brown staining from leaching through the white topcoat).
5. Apply the topcoat at the data sheet rate: for Henry 887, one coat at 1.5 gallons per 100 sq ft, applied between 35 and 120 degrees F; for Henry 287, the first of two coats at 1.0 to 1.25 gallons per 100 sq ft.
6. For a two-coat acrylic, apply the second coat (another 1.0 to 1.25 gallons per 100 sq ft) at right angles to the first after the first has dried; Henry recommends both coats on the same day where possible.
7. Inspect for thin spots, pinholes and missed seams, and touch up. Henry 887 must be pinhole free at a minimum 22 mils dry.

Coatings work on the surface only. They do not solve a structural problem; they buy time on an aging waterproof layer. If your mobile home roof has rotten decking, sagging trusses, or ponding deeper than the coating’s data sheet allows (Henry 287 excludes ponding areas entirely), no coating will fix it.

Full reroof path: tearing off and replacing

A full reroof tears off the existing roofing material down to the substrate (sheathing on peaked roofs, the metal skin or roof framing on flat low-slope homes) and installs new material. HomeGuide adds $1 to $2 per square foot for removing and disposing of the old roofing and $2 to $5 per square foot where decking has to be replaced, so tear-off condition can move a single-wide quote by $1,500 or more.

On a peaked mobile home roof, the project looks almost identical to a conventional home reroof. Tear off old shingles, inspect and replace damaged sheathing, install drip edge and underlayment, install new shingles. Pricing per square is similar to conventional work, but the smaller roof area lowers the total: HomeGuide’s size table puts a 16×80 home (1,280 sq ft) at $3,800 to $10,200 and a 32×60 double-wide (1,920 sq ft) at $5,800 to $15,400. If runoff off the new drip edge splashes the skirting or walls, our guide to mobile home mini gutters covers the narrow channels sized for small roofs.

HomeGuide’s mobile home shingle range is $3 to $5 per sq ft installed, below the $5 to $8 per sq ft for architectural asphalt on conventional homes in our 2026 roofing cost report. On a 1,000 sq ft (10-square) single-wide roof, those two ranges give $3,000 to $5,000 and $5,000 to $8,000, so ask which shingle line a low bid assumes.

On a flat low-slope mobile home roof, the reroof uses rolled roofing or a membrane system. Tear off old rolled roofing or coating, inspect and reseal the metal substrate or replace damaged sections, then install the new covering. Applying HomeGuide’s per-foot ranges to a 12×60 single-wide (720 sq ft):

• TPO membrane reroof, 720 sq ft: $2,880 to $7,200 at $4 to $10 per sq ft. See TPO vs EPDM roofing.
• EPDM rubber reroof, 720 sq ft: $2,880 to $7,200 at the same $4 to $10 per sq ft.
• Modified bitumen: priced like other low-slope membranes; see modified bitumen roof.
• Rolled roofing: legal down to 1:12 under IRC R905.5.2, below which only membranes and coatings apply.

For double-wides, scale by roof area: HomeGuide’s 27×52 (1,404 sq ft) home runs $4,200 to $11,200 against $2,400 to $6,300 for a 14×56 (784 sq ft) single-wide.

Reroof is the path when you plan to own the home 8 or more years: HomeGuide’s lifespans run 15 to 30 years for shingles, 15 to 25 for EPDM and 10 to 25 for TPO. Manufacturer warranties on those products apply on a mobile home the same way as on a site-built home, provided the install follows the maker’s specifications for slope, underlayment and fastening.

Metal roof-over installation

A metal roof-over installs a new metal roof (either a new peaked frame or a low-slope metal panel system) directly over the existing roof. HomeGuide puts metal on a mobile home at $5 to $16 per square foot installed and its life at 30 to 80 years, longer than the 30 to 50 years HomeGuide gives for the typical mobile home itself.

The two variants:

• Peaked-style metal roof-over: a kit creates a new sloped roof above the existing flat or low-slope roof. The new roof is supported by a perimeter beam and intermediate trusses, with metal panels on top, and the original roof becomes a sealed-in attic space. HomeGuide prices added roof framing at $6 to $15 per square foot, which is $4,320 to $10,800 for the framing on a 720 sq ft single-wide before panels.
• Low-slope metal panel: corrugated metal or standing seam panels installed over the existing low-slope roof, typically on purlins or directly to the metal substrate. Standing seam is allowed down to 1/4:12 under IRC R905.10.2, and lapped panels without sealant need 3:12. See standing seam metal roof cost and corrugated metal roofing.

The roof-over kit category is what most owners mean by “mobile home roof over kits.” HomeGuide puts DIY roof-over kits at $800 to $2,900 and a contractor roof-over at $1,000 to $4,500, and notes a single-wide roof-over takes about 1 day. Makers such as Ballew’s Aluminum Products sell aluminum roofover systems by quote, and the kit includes panels, fasteners, ridge caps and trim.

The structural addition of a peaked roof-over is what makes the project complicated. The added framing and panels need to be checked against the 20, 30 or 40 psf roof load and the wind zone on the data plate under 24 CFR 3280.305. Ask the kit maker for an engineering letter for your home’s size, roof load zone and wind zone before install, and keep it with the permit file for your insurer.

For metal roof installation on conventional homes, see our full install guide; the same principles apply at smaller scale.

Cost comparison: choosing the path

Dividing cost by HomeGuide’s lifespans: a $3,600 shingle reroof that lasts 15 to 30 years works out to $120 to $240 per year on the single-wide, while a $3,600 to $11,520 metal roof over 30 to 80 years is $45 to $384 per year. Metal wins per year only if you will keep the home long enough to use the extra life.

Climate-matched mobile home roof picks

Mobile home roofs are designed for lighter loads than most site-built roofs: 20 psf live load in HUD’s South zone and 9 psf uplift in Wind Zone I under 24 CFR 3280.305. Climate decides which material survives those limits.

Maintenance schedule for mobile home roofs

A mobile home roof needs more attention than a conventional roof of the same age because the marriage line on double-wides and the sealant joints required by 24 CFR 3280.307 are where water gets in. A regular maintenance cycle catches small problems before they become reroofing decisions.

Single-wide vs. double-wide cost differences

Double-wide mobile homes cost more for roof work mainly because of area: HomeGuide’s size table runs $2,400 to $6,300 for a 14×56 (784 sq ft) home and $5,800 to $15,400 for a 32×60 (1,920 sq ft) home, about 2.4 times the cost for 2.4 times the area. The other differences:

• Larger roof area means more material (linear scaling)
• Fixed costs (mobilization, dump, permit) spread across more area
• The marriage line between the two halves of a double-wide is a recurring leak point that requires special attention
• Double-wides often have peaked roofs where the ridge runs along the marriage line, so the ridge cap and the seam sealing are one detail

The marriage line is the seam where the two halves of a double-wide connect on site, and 24 CFR 3280.307 requires joints in the exterior covering to be designed and assembled against air and water infiltration. It is the first place to inspect when a double-wide leaks. Any coating or reroof must seal this seam with seam tape and a flexible sealant that can handle the slight movement between the two halves.

DIY vs. pro: what HUD code allows

HUD code does not prohibit homeowner DIY roof work, but several practical constraints push most reroofs toward licensed contractors:

• Manufacturer warranty: coating and roof-over warranties are tied to the maker’s application rules (for example, Henry 887 at 1.5 gallons per 100 sq ft and 22 mils dry); read whether the warranty requires a registered contractor
• Insurance: many homeowner’s insurance policies require licensed contractor work for roof claims
• Lender requirements: if the home has a mortgage, the lender may require licensed contractor roof work as a condition of insurance compliance
• Wind zone compliance: matching the original HUD wind zone fastening requires reading the data plate under 24 CFR 3280.5 and the -39 psf (Zone II) or -47 psf (Zone III) roof covering pressures

What is realistic DIY:

• Acrylic or silicone coating on a low-slope flat roof: very realistic. 1 to 2 weekend project. See coating instructions above.
• Patches and minor repair: realistic with seam tape and polyurethane sealant.
• Rolled roofing on a small roof at 1:12 or steeper: realistic for an experienced DIYer.
• Full asphalt shingle reroof: stretch goal. Requires 2 to 3 people, ladders, and knowledge of shingle install patterns and wind zone fastening.
• Metal roof-over kit: HomeGuide prices DIY kits at $800 to $2,900, but panel handling and structural integration usually need crew labor.

For pro install, ask contractors three questions: how many manufactured homes they have roofed, how they will match the wind zone on your data plate, and how they will seal the marriage line. A residential roofer who has never worked on a mobile home may not know the 24 CFR 3280.305 load limits. See how to choose a roofing contractor.

Insurance considerations

Mobile home insurance treats roof age and condition as an underwriting factor, and carriers set their own age cut-offs, so ask your carrier for its written roof-age rule before choosing a path. In Florida, Florida Statutes s. 627.7011 sets two rules for homeowner’s policies:

• An insurer may not refuse to issue or renew a homeowner’s policy solely because the roof is less than 15 years old.
• For a roof at least 15 years old, the insurer must let the homeowner get a roof inspection by an authorized inspector, at the homeowner’s expense, before requiring replacement as a condition of coverage.
• Visible roof damage (sagging, missing shingles, exposed substrate) is the kind of condition an inspection will flag in any state.
• Keep receipts, the product data sheet and the contractor warranty for any reroof or coating so the underwriter can date the roof.
• Metal roofing is rated for long life (30 to 80 years per HomeGuide), which helps when a carrier prices by roof age.

A coating documented with a contractor warranty can help an underwriter date the roof surface, but a coating does not reset the age of the roof underneath in every carrier’s rules, and Florida’s 15-year rule in s. 627.7011 is written around roof age. Ask whether your carrier counts a full recoat as a new roof before paying for one to satisfy a renewal.

For high-risk areas (Florida, Gulf Coast, tornado alley), some carriers require specific roof types or fastening. Check with your carrier before choosing the path, and match the fastening to the Zone II or Zone III pressures in 24 CFR 3280.305 if the home sits in a listed county.

Resale value impact

A mobile home buyer prices the home mainly on age, size, and lot rent (for park homes) or land value (for owned land), so the roof acts as a pass/fail item rather than a premium. No published resale study isolates the payback of a new roof on manufactured homes, so treat any fixed percentage as opinion. HomeGuide’s point that most mobile homes last 30 to 50 years is the more useful check: a 30 to 80 year metal roof on a 35-year-old home may outlast the home.

What this means in practice:

• If the existing roof is leaking or near end of life and you are selling within 2 years, a coating at $0.50 to $4.50 per sq ft (HomeGuide) removes a leak that a buyer’s inspector would flag.
• If the existing roof is functional but cosmetically tired and you are selling within 2 years, no reroof is usually justified.
• If you plan to own the home 5 or more years, choose the path based on cost per year of life (see comparison above) rather than resale optics.
• A metal roof-over is the most expensive path at $5 to $16 per sq ft and pays back only through years of use, not at a quick sale.

When to walk away

Some mobile home roofs are not worth fixing. Signs that the roof is beyond reasonable repair:

• Structural sag visible from the ground: trusses or rafters have failed, and the roof no longer meets the 20 to 40 psf design load in 24 CFR 3280.305. Repair requires opening the ceiling and re-engineering the structure.
• Interior ceiling stains across multiple rooms with no clear single leak source: indicates widespread substrate failure, and HomeGuide’s $2 to $5 per sq ft decking replacement applies to much of the roof.
• Pre-1976 home (no HUD code) with original roof: built before the June 15, 1976 HUD code, so there is no data plate roof load or wind zone to design against.
• Insurance denial: if no carrier will write a policy because of roof condition or age, the home is functionally uninsurable.
• Cost of work over 25 percent of home market value: use this as an editorial rule of thumb; above it, replacement (a new manufactured or modular home) deserves a quote alongside the repair.

For homes in this category, get a cash offer for the home as-is from a manufactured home buyer, price demolition and replacement if you own the land, or coordinate with the park owner if the home sits on a leased lot. HomeGuide’s 30 to 50 year typical life for a mobile home is the benchmark for how much roof the home can still use.

Common mobile home roof mistakes

• Layering shingles over existing shingles. A second layer adds dead load to a roof designed for 20 to 40 psf live load under 24 CFR 3280.305. Tear off before reroofing.
• Skipping the marriage line seal on a double-wide. 24 CFR 3280.307 requires covering joints sealed against air and water. Use seam tape plus flexible sealant.
• Wrong coating type for the substrate. The Henry 287 acrylic data sheet excludes rubber and PVC sheet roofing and ponding areas. Read the manufacturer compatibility chart.
• Coating ponding water without prep. Acrylic is not rated for standing water (Henry 287). Use a silicone rated for it or fix the ponding first (slope correction, drain add).
• No engineering letter for a peaked roof-over. Without it you cannot show the insurer or inspector that the added framing fits the 20, 30 or 40 psf data plate roof load.
• Cheap fasteners on a coastal install. 24 CFR 3280.307 requires corrosion resistant fasteners on exterior coverings. Use stainless or coastal-rated fasteners in Zones II and III.
• Ignoring the data plate wind zone. Roof coverings in Zone II must resist -39 psf and in Zone III -47 psf, rising to -73 and -89 psf within 3 feet of gable ends.
• Trusting a “lifetime” coating claim. A lifetime limited warranty (Henry 887) still depends on applying 1.5 gallons per 100 sq ft and 22 mils dry; read the coverage conditions.

Inspection: what to check before pricing the work

Before getting bids, inspect (or have a contractor inspect) these items. Document with photos.

• Existing roof material and condition (is it metal, rolled asphalt, shingles, coated, or layered?)
• Visible damage: holes, soft spots, blisters, peeling, separated seams, exposed substrate
• Ridge or marriage line condition
• Penetrations (vents, pipes, skylights) and their flashing condition
• Drip edge / fascia condition
• Interior ceiling: stains, sagging, mold
• Data plate location and wind zone designation
• Year of manufacture and HUD code status (pre or post 1976)

Photos of all of the above, plus the roof slope (for example 1:12 or 3:12) and the data plate’s roof load and wind zones, let contractors price the same scope and prevent surprise change orders. For deeper background, see signs you need a new roof.

Compared to a conventional home roof

A mobile home roof differs from a conventional home roof in several ways that matter for material and contractor choice:

• Lighter structure: lower dead load capacity. No piling on heavy material.
• Lower slope: many mobile home roofs are below 2:12, which rules out shingles under IRC R905.2.2.
• Smaller area: HomeGuide’s size table runs from 518 sq ft (14×37) to 3,182 sq ft (43×74). Mobilization and fixed costs become a larger percentage of the bid.
• Marriage line on double-wides: unique to manufactured housing.
• HUD code constraints: in addition to or instead of local IRC code, depending on state.
• Different buyer pool: mobile home buyers price on age, size and lot rent more than on roof upgrades.

For conventional roof pricing benchmarks see how much does a new roof cost. HomeGuide’s mobile home shingle range of $3 to $5 per sq ft sits below our $5 to $8 per sq ft for conventional architectural asphalt, so expect mobile home bids per square foot to run lower but not proportionally on very small roofs.
