The flat roofs on mobile homes can be prone to leaks and damage over time due to exposure to the elements. Repairing or replacing these roofs properly is crucial for preventing costly water damage on the interior. There are several good options for repairing or replacing flat mobile home roofs to consider.
Assessing the Roof and Damage
Before deciding on how to repair or replace the flat roof on a mobile home, a thorough inspection and assessment should be done to determine the extent of any damage or deficiencies.
Look for signs of:
- Cracked, curling, or loose roofing materials
- Ponding water or signs of leaking
- Rot or soft spots in the roof deck
- Damaged flashing around vents, skylights, etc.
- Deteriorating seams or seals
- Damaged underlayment
Pinpointing the sources of leaks or weaknesses will help determine the best repair approach. In some cases, spot repairs may suffice, but more extensive roof replacement may be needed for aged roofs in poor overall condition.
Cleaning and Prepping the Roof
Once inspected, clean the roof surface thoroughly by sweeping and washing to remove any dirt, debris, or contaminants before making repairs. Check for and remove any sharp objects or protruding nails/fasteners that could puncture new materials.
Any rotted or damaged sections of the roof deck will need to be repaired or replaced as well. Install new decking material to match the existing and fasten it securely.
Proper prep work helps ensure repairs adhere and perform properly over time.
Coating Options
Applying elastomeric roof coatings is one way to repair and restore flat mobile home roofs. These thick, rubberized coatings provide a protective waterproof barrier and help seal leaks, cracks, and seams.
Benefits of elastomeric coatings:
- Relatively low cost option
- Can extend roof life 5-10 years
- Energy efficient – reflects heat
- Seamless waterproof membrane
- Flexible to move with roof
- Can apply over existing materials
Drawbacks:
- Temporary fix, will need reapplication over time
- Messy, labor intensive application
- Surface must be clean and dry first
When applying a roof coating:
- Clean and dry the roof thoroughly first
- Repair any damaged areas or flaws
- Apply primer if needed
- Roll on 2-3 coats of elastomeric coating
Elastomeric coatings come in both white and colored varieties. White reflects heat best.
Membrane Options
Installing new membrane over the existing flat mobile home roof is another repair approach. Thermoplastic and EPDM membranes are common options.
Thermoplastic Membranes
Thermoplastic roofing is durable, versatile, and great for flat or low-slope mobile home roofs. Popular materials like TPO and PVC are lightweight, UV/weather resistant, and easy to install using heat welding.
Benefits of thermoplastic membranes:
- Seamless, flexible, waterproof barrier
- Long lifespan – up to 20 years
- Energy efficient
- Can install over existing roof
- Variety of colors available
Potential drawbacks:
- Higher upfront cost than some options
- Professional installation advised
- Seams can be tricky for DIYers
- Not compatible with petroleum-based products
Proper cleaning and prep work is vital prior to membrane installation. The roof surface must be free of dirt, oils, and other residue. Damaged areas should be repaired and reinforced.
Large sheets of membrane are rolled out and sealed using hot air welding equipment. Perimeter flashing and detailing is crucial for a watertight seal.
EPDM Membrane
EPDM (rubber) is another common membrane option for mobile homes. It is flexible, durable, and easy to install, making DIY installation feasible.
Benefits of EPDM membrane:
- Extremely flexible and durable material
- Seamless, waterproof sheet when installed
- Can stretch and move with roof
- Easy to install, good for DIYers
- Energy efficient roofing choice
Potential cons:
- Seams can be tricky and must be carefully sealed
- Requires compatible adhesives/sealants
- Shorter lifespan than thermoplastics – 10-15 years
- Black color absorbs heat, less energy efficient
As with other membranes, proper surface prep is essential before installing EPDM over a flat mobile home roof. Damaged areas must be patched and materials removed. The roof deck should be reinforced if needed.
Large EPDM sheets are rolled out and sealed using adhesives or tape. All seams must be carefully sealed to prevent leaks. Flashing details are important as well.
Alternative Systems
Beyond coatings and membranes, some other options for repairing or replacing flat mobile home roofs include:
- Spray polyurethane foam – Foam is spray applied to form a protective, insulated, and seamless roof covering. Makes an effective repair option.
- Metal roofing – Durable and weather-resistant, metal panels can be installed over flat mobile home roofs. Provides good protection.
- Modified bitumen – Rolled material with polymer-modified asphalt. Offers durability and good water resistance.
- Roof restoration system – Layers of reinforcements, adhesives, and surfacing to create a new roof surface.
- Liquid-applied systems – Sealants, primers, or coatings rolled or sprayed in layers to waterproof the roof.
Proper prep work is vital with any system. Consider options carefully to balance effectiveness, roof life, energy efficiency, and costs.
Working With Professionals
While minor repairs can sometimes be tackled by mobile home owners themselves, extensive roof replacement is usually best left to experienced professionals. Hiring a qualified mobile home roofing contractor is advisable for several reasons:
- Expertise in proper roofing methods and materials – They understand flat mobile home roofing needs and have the skills to do the job right.
- Access to special equipment – Tools for cleaning, seam welding, lifting materials onto the roof, etc.
- Knowledge of building codes – A contractor will ensure any roofing solutions meet the proper codes and standards.
- Insurance and liability protection – You get coverage for workers on your property and roof work guarantees.
- Efficiency – They’ll get the job done faster than a DIY approach.

Get quotes from several properly credentialed local contractors before selecting one. Check references too.
