type of caulking required for thermoplastic polyolefins (TPO) roofs and the correct
methods of resealing. Silicones and synthetic sealers cannot be used on the rubber
roofs. Special sealers are also required for the skylights. Your Thor Motor Coach dealer
may perform the periodic roof seals for you if desired.
It is especially important to check the seals before and after periods of extended storage
or non-use. Fall and spring inspections are recommended. Check the membrane for
possible damage and check all accessories and fasteners. The roof may be cut or
punctured by sharp objects so care must be taken when parking and driving. If damage
does occur, the roof may be patched. Check with your dealer for additional information.
Parking in areas where fruits, nuts or tree sap may stay on the roof for extended
periods of time may result in irremovable stains.
For Normal Cleaning:
•
Use a mild laundry detergent.
•
Rinse the complete roof with clean water to remove any loose dirt or debris.
•
Use a medium nylon bristle brush along with your selected cleanser mixed with
water and scrub the entire roof. Rinse thoroughly with clean water to avoid residue
buildup on the roof or sidewall of the unit.
•
For more difficult stains contact your Thor Motor Coach dealer for the correct
heavy duty cleansers. Do not use general-purpose cleaners containing petroleum
solvents, harsh abrasives, or citric based cleaners.
If your roof should somehow be punctured, cover the puncture to seal out moisture,
and have it repaired as soon as possible (check with your dealer).
The membranes used on the roof may have an extended warranty that is covered
by the membrane manufacturer. This is for manufacturing defects only and does not
include leaks or punctures due to improper sealing, normal wear and tear, or owner
damage. See membrane manufacturer's warranty for details.
Check roof vents regularly for debris that may block air flow or jam the cranking
mechanism. Lubricate the cranking mechanism with light oil.
Failure to maintain seals through regular maintenance can lead to damage of
motorhome components, and may be considered abusive treatment under terms of
your motorhome warranty.
It is important to maintain the seals and adhesives of your recreational vehicle to
prevent moisture from entering and destroying the components. When washing your
recreational vehicle, inspect the seals for signs of drying out, cracking and wear. You
should inspect and reseal, if necessary, every six months at minimum.
that weather, sun, and road vibration will affect seals, causing them to dry, crack, or
separate. If you are unsure what to look for, have your dealer instruct you, and also
show you the correct method for renewing the seals. If you prefer, they will be able to
perform seal maintenance for your convenience.
Note:
It is especially important to check the seals before and after
periods of extended storage or non-use. Fall and spring
inspections are recommended.
•
Check seals around doors, windows, vents and external seams. If a seal is cracked
or dried out, it should be replaced to prevent leakage.
