I have a flat roof situation where I need a railing on the balcony. I do not like the idea of penetrating the roof with 4 x 4’s. has anyone used a surface mount bracket with a gasket of any kind? any other ideas would be appreciated.
here is a pic

Listeners write in about haunted pipes and building-science tomes, and they ask questions about roof venting and roof leaks.

Are those columns on each end structural?
If so how long is the span?

The posts yu see on the porch are temporary - I have since put in te final posts. The place where I am working now is on the balcony under the arc section. that is where I have a torc down roof that I ned to mount posts within the archway. the with of the opening is about 20 feet so I will need to mount 2 posts."it aint the work I mind,

Your railing is going to have to comply with the building code for strength, resistance to lateral loads and spacing of balusters. On the span shown in your photograph (16'-18'?), if this is going to be a wood railing you are going to need to have intermediate newel posts or balusters that are attached through the roofing to structure. There are some good ways of doing this, but sitting on top of the roof membrane isn't generally one of them.
If you are planning a metal railing you can probably get by with fewer points of anchorage but you still have to do it.

I realize the requirements ut I also have repaired and replaced rotted posts in flat roofs that have leaked because they are difficult to flash. I found this place on line. I ordered a sample anchor to check it out. What do you think?http://www.ideasfordeckdesigns.com/titanpostanchor.htmlThanks for the reply,Jason"it aint the work I mind,

If you go with that go to the boat supply yard and get a bedding compound to set it in. I believe they are polysulfides.

Jason that seems to be a base for exposed-wood decks.
Tried and true - run treated rough post up through roof attached to structure. Run roofing up post and terminate. Cover remainder of post with Vycor or similar adhesive flashing. Slip box newel of 1 x cedar (or spanish cedar or other rot-resistant wood) with pitched cap over post - run railing through to structural post and seal.
