Tar as roof coating?
The recent thread regarding roof coating reminds me that I need to have some similar work done. The guy I use tells me that it should be done about every 2 years to the tune of some $$$$.
Short of going with a galvanized roof instead of wood, is there a way to avoid having to do this so often? How about a tar coating over the wood? Or is that a problem if the roof is feeding a cistern? Suggestions appreciated.
I'd sure go with galvanized roofing over tar if your cistern is involved. Just my opinion, but I'd think besides the health factor the water would taste funny & wouldn't tar get pretty melty in the hot sun here? Hope somebody shows up with a better answer for you.
Tar or asphalt roofing is common, provides a good water seal however does nothing to reflect the suns rays and I would never apply it and then collect water which runs off it for anything.
Take a trip to Home Depot, the most modern products are elastomeric roof coatings. The very best is called Flex-on, which is a two part process, once the roof has been cleaned and dried you paint on a primer, once the primer dries you paint on the sealer, it dries brilliant white and you typically see a 20% reduction in house temperatures.
You can go with a single stage product like Crossco 5500, which is the primer and sealer all in one, applies the same way. I have been paying $145.00 per 5 gallons here on PR A 5 gallon pail will cover 350 square feet.
This is certainly a project a do-it-yourself-er can do, its hot, dirty work and there are some physical challenges, like carrying the 5 gallon pails around and you have to pressure wash/clean the roof thoroughly.

Hope this helps.
P.S. If any landlords or property managers read this, I am seeking housing on STT and can provide contractor quality maintenance in exchange for reduced rent. Yes, references available.
Go to Sea Chest and get Top Coat, which is safe for water going into the cisterns. Have ck'd into this myself and Top Coat is the only way to go OTHER than using galvanized roofing!
Thanks for the suggestions. Very useful indeed. You all are terrific!
I would vote for The Paint Depot and Vulkem! 340-775-1466.
We had our roof recoated this year and the gentleman who did the work used Vulkem from The Paint Depot.
EE and dnt, the Vulkem line is apparently cheaper than Topcoat. Are you happy with it and is it safe for cistern use? It's our turn to do the roof and I am trying to get Topcoat options. Thanks!
We're very pleased with Vulkem and yes, it is safe for cistern use.
Onika: Very happy with it and the integrity of the people who run Paint Depot. Thumbs up.
