Inspecting Your RV Roof Pays Dividends

RV roof sealantWater damage is at the top of my list for maintenance concerns on RVs, and most of the time it originates at the roof. There are numerous reasons for this. Every where the manufacturer cut a hole in the RV roof has the potential to leak, and everywhere the sidewalls and end caps meet the roof is another potential source for water leaks. When you add all the twisting and flexing that takes place on the road it’s just a matter of time before sealants give way to water intrusion and damage.

The good news is a little preventive maintenance helps avoid this costly damage from happening to your RV. Sealants used on RV roofs do a good job, but eventually they dry-out, crack and allow water to penetrate the surface. RV manufacturers are aware of these issues and if you read your owner’s manuals most manufacturers require routine inspections of the roof and sealants for the warranty to remain effective. The reason for this is simple, periodic inspections of the roof seams and sealants will reveal problems that can be corrected before it results in expensive repair bills.

There are safety concerns anytime you work on the RV roof, and if you are not comfortable doing this type of work have it done by a reputable RV repair facility. You also want to make sure the roof on your RV can support your weight. Some RV roofs are not designed to be walked on. Always exercise caution when you work on the RV roof, a fall can result in serious injury or death.

I always say the key to these inspections is to get on your hands and knees and thoroughly inspect all of the seams and sealants.

A small crack or opening can allow water to penetrate the roof’s surface. If you find a potential leak you want to seal it with a sealant designed specifically for the roofing material on your RV. Consult your RV owner’s manual or local RV dealer for proper sealants. It’s not necessary to completely remove the old sealant unless it is cracking or peeling away from the surface. Clean the area thoroughly (you can use denatured alcohol on a clean cloth) and seal the area with a compatible sealant.

If you get into a habit of periodically inspecting and sealing the RV roof you will extend the life of the RV and avoid any issues with your RV warranty. For more information on you RV roof, roof maintenance and helpful videos click here.
