What Is The Best Sealant For A Mobile Home Roof?


Water is the most damaging force of Mother Nature on earth and your RV roof is the main line of defense against it. Preventive maintenance and inspections helps a lot but even the most maintained roof will wear out and will eventually begin leaking. Different mobile homes have different roof structures that call for different materials and different techniques for repair and replacement. 

What Is The Best Sealant For A Mobile Home Roof?

Two Designs for Mobile Home Roofing

1.       Flat and Bowed Roofs

Mobile homes built before June 1976 usually have flat or bowed roofs, covered with sheet metal or asphalt coating. Flat RV roofs are supposed to be coated every couple of years or so, based on the manufacturer's recommendations. Coating the roof provides two benefits; the coated roof reflects harmful UV-rays and second it prevents the roof from leaking. Repairs and maintenance can extend the life of the roof but eventually the entire roofing system will need to be replaced.

2.       Peaked Roofs

Mobile homes manufactured after 1976 generally have more pitched, or peaked roofs. Peaked or pitched roofs are often covered with traditional asphalt shingles or metal roofing panels, much like traditional frame-built homes. Structurally, the roofs are formed with standard trusses fabricated with a fairly shallow pitch.

“Roof over” Repair Solutions

1.       DIY Seamless Rubber Roof

A seamless rubber roof is actually a thick coating of liquid rubber e.g. (Liquid Roof Coatings) spread evenly on the roof. Before you apply Liquid Roof, you first have to clean the roof and remove any old sealant. Also the seams and vent flashing are sealed with a rubber neoprene product. Seamless rubber roofing is DIY roofing easily applied by the homeowner.

2.       Membrane Roof

A variety of different flexible membrane materials can be used to overlay the existing roof. These are generally installed by professionals, not by DIYers or owners. EPDM, PVC and TPO membranes can be installed over the existing membrane. Membrane roof-overs are relatively rare on peaked roofs as metal and traditional shingles roofs are used much more often. 

3.       Corrugated Metal Roof

Installing a corrugated metal roof is the best option of all. It involves the cutting and fitting sheets of corrugated roofing onto wood battens installed against the old roof. It is a simple DIY project, and also a fairly inexpensive one. Many new roofs will cost less than $1,000.


Repairing RV roof is not complicated as many may think. When it comes to RV, a DIY owner can usually tackle most of the issues. Liquid Roofing the RV only requires a steady hand a bit of hand practice. All you have to do is to follow the instructions on the container, clean and prep the roof, and, most importantly, be safe when working on your roof.
