Roof reseal options
My RV is 7 years old and could use to have a complete caulking job on the roof for the front cap, back seam, and all vents, antenna, and the bathroom skylight. I've done a complete job before on my fi...

I just did this job a few weeks ago. I, too, was reluctant to climb on the roof. I decided to use ladders (step and extendable type like Little Giant) and placed them along the sides and rear as I went all around the trailer. I have a shop nearby and the guys are great about sharing advice. They do excellent work but charge $120/hr...doesn't matter the type of work.
The plan as suggested by shop....
1. Day 1: Clean all caulking areas to be caulked with Dicor Roof Cleaner. I used a spray bottle and cleaned with micro fiber rags. Remove any loose pieces of caulking but no need to scrape off old caulk.
2. Day 2: Use Dicor self-leveling caulk (verify which roof you have and follow manufacturer's recs). I believe Dicor SL sealant is suitable for EPDM, TPO, and roofing materials. My roof is EPDM. Apply caulk, with an approx. bead of 1/4", to all areas where cracking is noticed. ALL old caulking does not have to be covered with new caulk; only areas where caulk has cracked and water can enter. It's pretty straightforward and not difficult.
3. 2-3 weeks later....wash roof with Dicor roof cleaner and medium soft RV brush.
Next day after roof has dried, I applied a Roof Treatment. It keeps the roof membrane conditioned, protected from UV rays, and prevents roof from drying out.
The area I was unable to reach by ladder, was the center vent. Since I want to install a Fantastic Fan in this vent, I did not clean/caulk, as the entire vent will be removed for new Fantastic fan. ALL other items were reachable by ladder (bathroom vent, roof vents, refer vent, TV antenna, front and rear seams). I was even able to install a new Vortex II fan and a Maxx Air II cover at bathroom vent.
