Roof paint for 08 dynasty

[Bobbyboy]

For years I have been faithfully using Mop n Glow on my roof probably every six months.  However my roof is now starting to "chaulk up" and when it rains I get the white streaks down the sides.  I am looking for suggestions for coating (or painting) the roof to prevent this.  ANyone have the same problem and cured it??   Thanks for any info that is available.

I used Henrys tropicool from home depot, i had to do quite a bit of prep work but it came out awsome, there were some you tubes on roof painting rvs that helped. The pic was before i put all the covers back on. It has great coverage, and laid down well, very good refelective ability. I used almost a 5 gallon bucket of paint an my coach is 36ft cost was under $500
