Removing semi-transparent stain on deck on roof

I have a large deck on my roof with failing semi-transparent stain. I want to remove it and use just a clear sealer. The wood is cedar and around 2-3 years old.

At my last place, I had great luck using Restore-a-Deck on my cedar deck and poor luck with just a power washer and several other products. It did remove the paint off of some aluminum trim.

My roof is rubber with an aluminum (silver) coating. My question is can I use this product to strip the deck or will it remove my roof coating? If I cannot use that, any other recommendations? We are talking around a 500 sq ft deck, so the easier the better.

I've had little luck with a pressure washer. Too low pressure and it doesn't remove anything and too high and it damages the wood.

You might not need to remove all of the old stain depending on what you intend to coat it with. I usually use TSP and bleach water along with a pressure washer to clean the deck prior to restaining. That may not remove all the stain but will remove any that isn't adhered well.

The old sealer was a medium brown. I would say there is about 80-90% of it left. Looks terrible. I think it was a mistake trying to use a semi-transparent vs clear. The sun is intense up there. All my neighbors decks are peeling as well.

Generally the more pigment a stain has the longer it will hold up [assuming the quality is the same] I've never used Restore-a Deck but most deck stain strippers should be ok over your roof. Rinsing the roof well will further insure it doesn't hurt the roof.

I ordered the restore-a-deck stripper. I'll try it on a small area of the roof where the roof curves up.

I had great luck with it in the past making an 11 year old deck look new. My Father used the remainder on a 25 yr old deck that had solid stain and said it worked unbelievably easy. The stuff I've tried from big box stores just didn;t work.
