   I hade leaks coming thruogh the small block foundation on our sunroom. I used drylock it worked great. Weather around here in New England has been bad this year and no leaks  yet. I do think I will repaint every couple of years though. It might not be very practical for a roof.

   Drylok is not your answer. If your fiberglass shingle roof were leaking and someone told you that painting it with Drylok or another paint product could get you another 3 years, would you do it ? Probably not. More than likely, you need a new roof.

   What was the result of the settled suit ?

   It is not fiberglass; it is woodfiber-cement shingle that looks like cedar shake - it looks very nice and had a 50-year warranty. The finish on it started flaking and once that coating was breached rainwater soaked through. Cemwood settled by reimbursing homeowners the cost of the roofing material. Since it is cement-based, I thought cement waterproofing like DryLok would work, although evidently I would have to reapply it every 5 years according to the DryLok warranty. DryLok Lab has no experience with this particular application but stands behind their warranty. It is supposed to be UV-resistant.

   Consumer Reports recently rated basement waterproofing paints and found that Dry Lock was about the only one that worked.  It was significantly better than all the other brands tested.

   It wouldn't do much for your nail holes, though.

   Thanks for that encouraging report on DryLok. If it effectively seals the surface, thus preventing water from reaching the nailheads underneath the top layer then it will probably work. My remaining concern is that I would probably have to repeat the application at least every 5 years, the maximum warranty. Still better I think than replacing the roof, which really looks nice.

   Mac,

   I'm not trying to be a pain, I understand that you like the look of your roof and you don't want to replace it. If you are willing to get up on the tiles and spend the time necessary to coat them, then go ahead and give it a try. I just wouldn't assume that you are going to get 5 years out of a paint job on a horizontal roof surface. Their product line is designed for use on vertical surfaces. Take a look here:

   I'm sure you have already been there, but, I would give UGL a call and ask for their thoughts on this.

   Hi Tim, I don't feel that you are being a pain. I rather appreciate your concern. I have been to the DryLok website and seen the description of their latex and oil-based cement waterproofing and written to their lab about roofing application. Truthfully they claimed no experience in this case but would stand on their five-year warranty. In the end it will have to be my call. Thanks for the warning. If I go ahead with it I'll be happy to post my experience and findings however many years down the line.

   Looking for Cemwood shake paint | Nov 25, 2015 11:16am | #8

   Looking for Cemwood Shake solutions

   We've had Cemwood Shake on without any significant leaks for almost two decades, but we live in Southern California and don't get that much rain.  I find if I don't walk on it it doesn't break, but on the west and south sides the original coating is mostly burned/worn off.  Wondering what I can paint it with that will give me another 5 - 10 years life.  Very hard to get a roofer without a 4 month delay out here due to the impending El Niino threat.

   Also wondering how that DryLok worked out for you?

   Appreciate any info anyone might have.
