FlexArmor is the Solution to Your RV Roof Air Conditioner Leaks

Different types of RV roof air conditioner

RVs have three different types of air conditioners; ducted, non-ducted and basement. Roof mounted air conditioners have two different bolt systems. Correct installation and maintenance of the ACs on the roof is an important deterrent to roof leaks.

Non-Ducted RV roof Air Conditioner

Non-ducted systems have the air return inside on the ceiling and the owner can see the grate and can change the air filter.  Non-ducted systems bolts are inside the RV located at the air return. Ducted systems mount on the roof by removing the cover, and drilling lag bolts down into the roof. The air conditioner bolted from the roof has no air return on the ceiling. A compression gasket is under the air conditioner and the bolts compress the gasket to form a seal.

Ducted RV roof Air Conditioner

Ducted systems are becoming more popular. The driving force behind this popularity is the air conditioner is quiet, similar to a house AC. Manufacturers are not communicating to consumers the added maintenance a ducted system requires. The lag bolts are screwed down into the roof through caulking. Caulking crumbles with age and should be routinely replaced. Leaks occur around these bolts on a regular basis. It is a slow, seeping leak and very rarely will an owner see damage inside. Since the bolts are located outside the AC compression gasket the water stays on the roof and never enters inside. Leaks are located by getting on the roof and inspecting the wood for soft areas.

Air conditioner related damage on RV roofs

Newmars and Redwood fifth wheels are the most common brands arriving at FlexArmor locations with AC related damage. Wood rot can be minor with a rubber roof. Units that have TPO roofs suffer the most damage in a short time. TPO roofs have a cotton backing that wicks the water and stays wet for extended periods of time.

How does FlexArmor help your RV roof air conditioner issues?

FlexArmor roofs remove this bolt issue. FlexArmor installs a mounting system before the spray roof application. Air conditioners sit on the mounting system.  The air conditioner pulls down on the compression gasket using nuts and washers. Owners do not have to remove the air conditioner and reseal the mounts, the area under the air conditioner is seamless and water tight.
