Roof Care & Seal Inspections
Periodic resealing of the joints and seams is necessary to prevent the entrance of moisture into the
motorhome. Enough emphasis cannot be placed on this issue. Extreme damage from a water leak can
occur rapidly. Never leave the motorhome unattended with the slide room extended. If the motorhome
is to be stored outside throughout the winter months, a full interior inspection for water leaks should be
made every two weeks.
Extensive sealing has been done at the factory; however, the normal twisting and flexing that occurs
while traveling may have compromised a seal or seam.
INSPECT:
All joints and seams should be inspected at least twice a year and recalked as neces-
sary.
Special attention should be directed toward the roof air conditioning seals, ceiling and plumbing vents,
skylights, roof mounted antennas, windows, door molding, clearance lights and the beltline molding.
Specific sealant products should be used in the areas for which they were designed. These items can be
obtained from recreational vehicle parts suppliers. Listed below are some of the more common sealants and
the areas in which they are used. Approved sealants are available at service centers and authorized dealers.
WARNING:
Some products may contain hazardous materials which require special handling. Read
labels carefully. Follow all of the product manufacturer’s safety requirements.
Sealant Types:
Tar Tape:
The tar tape is used on aluminum roofs seal seams at
the front, rear and down the center. The sealant is avail-
able as a peel and stick waterproof membrane that con-
tains UV inhibitors and is temperature resistant providing
superior seal protection in all types of weather. Store
sealant out of direct sunlight between 50º F and 90º F.
To Apply:
1. Clean the aluminum surface with Denatured
Alcohol.
2. Set the tar tape upon desired area, heat to a warm temperature allowing tape to form into
place.
3. Use a squeegee to mold sealant into cracks and seams, followed by a roller to roll out
tape to get a good uniform seal.
NOTE:
Check the tar tape at least twice a year for cracks. Removal of the tar tape is done
with a plastic putty stick. Thoroughly clean the surface using 3M adhesive cleaner
before applying the new tar tape.
