Tree sap on rubber roof

Leave it there. You can do more harm by trying to remove it.
A sap free, sparkling white roof is not a requirement for having a good time while RVing.

Do you remove tree sap from your house's roof?

I agree with leaving it alone. It will eventually dry up and probably just crack and blow away. Chemicals or tools to remove will just damage the roof.

Sap from many trees can be removed by blotting it with isopropyl alcohol and then washing the residue off with a mild detergent and water.

I would be surprised if alcohol would damage the roof but you probably ought to check.

I would never use a solvent on a rubber roof unless the manufacturer says it's OK. As far as the sap, I'd leave it. The less messing around with a rubber roof the better.

I wash my roof once a year in the spring --- when sap gets dry enough it comes off without use of any chemicals. Over the years I view the primary reason for "roof washing" is to examine potential problem areas on the roof rather than getting the roof sparkling clean.

I wash my roof with mild soap and water then treat it with 303 protectant twice a year, hopefully the UV protectant will make the roof and caulking along with the vent covers last longer, use it on the slide seals also.

In agreement with leaving the tree sap there.
Rubber roofs are tough and last at least 15-20 years with minimum care.

I spray our roof down monthly with water, wipe down with a large towel or mop then spray off and leave to dry.
Nothing else needed for a roof in good condition.

Be sure to keep the gutters and drip caps clean also.

Odds are it is not really tree sap; it's aphid poop (aka 'honey dew').

I do it once a year.
Hose off the heavy grime then use a long handle bristle brush to give it a good scrub.
Don't over do it or worry about getting every stain.

You won;t belive this but just put a ice cube on it & it will come right off did it to mine was amazed
