hello George,  the epoxy is actually for a basement floor to act as a sealant against moisture and keep dust down a little.

make sure to use that red waterproofing sealant.

They should use UV resistant flexible sealant and the roofer should tell you if the original install meets the building code.

A bead of sealant round the frame and wall would help to. 

Rob, I would advise getting a baseline mold test complete in these spaces, should be inexpensive maybe $100-$150You do not know if the company performing the mitigation and mold rendition used a viable protocol, bank owned homes, since they are really checked by the actual asset manager, they could have just applied kilz and never applied a proper biocide/mold inhibitor and possibly did not use a proper sealant.

Another said you need a "roof sealant" liquid to change the color.

@Sean Tippens I understand wanting to prep or treat the new siding with a good exterior paint & sealant.

Normally you would spray a sealant on the tile after grouting (or maybe that's only if it's marble, not sure) -- but if you spray the sealant BEFORE grouting, then the grout won't stick to the tile as much and is easier to wipe off (downside: your dance party doesn't last as long).

Just go to your local DIY supply stores and take notice of how many different types of sealant or spackle mud there are.
