How to clean 2005 roof?

[woodytwo]

I have white residue on the side of my 2005 LY 30 M/H everytime it rains. I assume that this is from the runoff from the roof. Several questions.
What type of roof did A/S use on these last models?
How to clean? I wash it once a year using a car wash brush, warm water with a car wash additive.
What if any protectorent to use?
Thanks in advance for your expertise.

My 2004 Land Yact has a fiberglass roof that I clean with a soft brush designed for washing a vehicle and car wash soap and water. I use a stiff brush in any dark areas on the sealant around any penetrations. As an aside, this is a good time to examine all the caulking and repair/replace any damaged or cracked sealant. Be sure to use a sealant designed for your roofing material. The sealant will be self leveling.

I do not use any protectorent on the roof.

I use 303 on all things needing UV protection, especially up on the roof.

Do you spray and leave or wipe off the 303?

Many years ago my local car club had a tech session with the inventor of 303 and I was very impressed with the comparison results he showed. I use it on my tires too. I've been using gel Gloss for wash and protection and it seems to be working very well, except I have not figured out how to train the hose, brush and wash solution to do the work without me "helping."

I scrub the roof annually with a soft RV brush to remove the dead pigment (white) along with sticky pollen and use GELGLOSS with good results. The GELGLOSS does a great job protecting my Airstream keeping it bright and shiney.

When I purchased my 93 LY the roof was badly soiled from all ways being parked outside. I went to a carwash that also had a bay for large trucks. I climbed up on the roof and power washed the complete roof, the pebbly fiberglas surface quite hard and I backed off on all the seams a little so as not to damage them. The high pressure got down into the rough surface making it look like new except for a couple of stains, I was amazed. The Owners manual recommends waxing periodically. when you start with a very clean roof, it looks great and the waxing is much easier to apply. The wax also allows for the water to bead up and run off faster not allowing dirt to collect as fast.

Sorry...missed your question.

Good stuff if you follow the directions.

What we absolutely swear by is "Simple Green". Using a half a cup of Simple green to two gallons of water in a bucket. Then using a soft long handled brush, off it comes with almost no scrubbing.
Taking the suds, let it stand for about a minute, then rinse off.
Look at this difference as it removes any residue as well as sap etc.
