All motor homes and travel trailers are equipped with some kind of roof venting system, the most common of which is the manual crank up version. Although relatively trouble free, these units - just like most things on an R.V. - require maintenance. Semi annual inspections of your total roof should detect the need to reseal your roof vents.

The most common mistake made with the R.V. roof vent is not replacing the cover often enough. If the shine is gone or the plastic is chalky to the touch replace the cover now. Trust me, it will disappear at the most inconvenient time, leaving the vent open after you are done with your camping trip or away from your camper for an extended length of time (you know this is when it rains the hardest).

Roof vent covers are produced by a number of manufactures; each using a different hinge attachment system. To insure the proper vent cover replacement is purchased, first look on your unit at the trim work or the crank handle to locate a manufacturer’s name. If it isn’t there, take careful note of the vent’s hinge system. The hinge can only be viewed from on top of your R.V., so please be careful.

Replacement covers made of plastic cost about $16.00 each, and some manufactures offer a metal cover $22.00 each (Note: no light infiltration.). A life-time warrantee cover is available from most vent manufactures for about $25.00 each.

A vent over cover is a great investment. This will enable you to leave the vent open all the time, helping to prevent mold, excessive heat build up, and persistent stale odors all without the possibility of water damage due to a sudden rain storm (or your neighbors sprinkler system). These covers also protect from sun damage and come in a variety of styles and colors from the simple $27.00 unit to the wireless remote controlled 4-speed reversing fan with thermostat $379.00 unit.

There are vents that open and close automatically according to temperature, turn off and on a fan as needed, and when a sensor located on top of the vent gets wet -- will close the cover for you. With endless possibilities all to fit your budget and needs the days of the simple crank it up crank it down vents are properly numbered.

To change the simple cover however, start by removing the trim ring, the crank handle, the screen assembly and the opening and closing operator all located inside your R.V. A screwdriver should do it. To remove the cover assembly, proceed to the roof again depending on the hinge your vent has (remove the screw, bend the tab, etc.) slide the cover left or right to remove. This is when you realize how important it was to be neat with your sealant when you applied it. Slide the new cover in place, return to the inside and reassemble the components you took apart. Check to make sure the cover opens and closes correctly before putting all your tools away.

After installing a new cover, check for water leaks around the vent, either by applying water with a water hose. A small leak over time can cause major damage to your R.V.

As always, I hope this helps you in the maintenance and enjoyment of your camper. May God Bless.
