3 Different Types Of RV Roofing
There are several different types of RV roofs – fiberglass, metal, and rubber.
This is the most common RV roof type. There are two different types of rubber roofs – the EPDM (Ethylene Propylene Diene) roof and the TPO (Thermal Polyolefin) roof. Rubber roofs are easy to determine because they're soft to the touch and are usually colored white. However, some older RV models might have tan or off-white rubber roofs. One disadvantage of this roof is that it develops a chalky texture as it ages.
This type of RV roofing is hard, durable and smooth. It's not as popular with RV owners because of the expense and weight it adds to the vehicle. But there are those who prefer it because it's in low maintenance. However, fiberglass RV roofs tend to get slippery when wet, so it can be challenging.
This type of roofing is rarely used in RVs. Like fiberglass, a metal or aluminum roof is heavy but rarely needs to be maintained. It's easy to distinguish by its silver metallic color and the support beams that are interspersed every two feet or so.
Importance Of Taking Care Of Your RV's Roof
Most RV owners forget about inspecting or cleaning their RV's roof before storage or going on a trip. But neglecting to check and clean the roof and its seams regularly could lead to water damage and other expensive repairs. So if you want to get the most of your RV, regular checking and cleaning are needed. There might even be times when you need to apply the best RV roof coating on it.
Here are some tips on how to maintain your RV's roof:
- Safety First: You have to go up your RV's roof in order to check and clean it. But you have to be very careful when doing this as some roofing materials tend to be very slippery or are not designed to be walked on. The lack of ladder or roof access means your RV's roof is not made to be walked on. You might have to use several pieces of plywood to distribute your weight. Check your owner's manual to be sure or tap an RV service to work on the roof.
- Clean on a Regular Basis: As a rule, RV roofs should be cleaned 3 to 4 times a year. However, maintenance should be done more often if RV is usually parked under trees. Regular cleaning will prevent early deterioration and buildup of algae or mould. It can also lessen stains caused by bird droppings and tree sap. A regular cleaning schedule will also minimise streaking of sidewalls.
- Use the Right Cleaning Materials: Check your owner's manual for the type of cleaning agents or soap appropriate for your RV's roof. Refrain from using cleaning materials that contain citric-based acids, harsh abrasives, or petroleum solvents on rubber roofs.
For normal cleaning, start by spraying the roof with clean water to get rid of dust and dirt. Next, apply your cleaning agent and gently scrub around in circles. You should use a bristle brush, cloth, sponge or any non-abrasive material. Rinse with clean water to minimize residue build-up on the roof or sidewalls. You should also gently rinse the sides of your RV. Be mindful of the paint or decals. Make sure you don't leave soapy streaks on the walls.
- Carefully Inspect the Whole Roof: Scan the roof for any signs of deterioration, like cracks, tears, punctures, or areas that might have lifted away from the material. You should also check the holding tank vents, air conditioner shroud, or refrigerator roof for any damages or breaks in the seal. Proper maintenance of seals is crucial in preventing moisture from entering the RV and causing mold, rot, or mildew. Inspections of your RV roofing should be done at least every six months.

Types Of RV Roof Coating
The roof is the most vital part of your RV, and the best RV roof coating can help keep your vehicle in tip-top shape. However, not all roof coatings are the same. Here are the different types of roof coatings available to RV owners.
- Aluminum Coating: This is one coating that's rarely used by RV owners. Aside from adding extra weight to the vehicle, RV roofs in today's models are rarely made from aluminum.
- Fiberglass Coating: This type of roof coating is also rarely used. It adds weight to the RV, is more expensive and hard to install. But it is low maintenance and can save RV owners money in the long run.
- Liquid Coating: This is the best RV roof coating for those who want to prevent roof corrosion and protection from ultraviolet rays. Because liquid roof coating is water repellant, it prevents the development of rust.
- Rubber Coating: Preferred by most RV owners, this coating is classified into two types – those made from ethylene propylene Diene monomer and thermal polyOlefin. The two types are maintained differently so owners should check their manuals to know which is the best for their RV.
Aside from the coating, sealing your RV roof is also crucial to its maintenance. Here's how you do it:
