Re-Roofing a Geodesic Dome
Re-Roofing a Geodesic Dome
I am working on a Geodesic Dome Re-Roof.
I did the construction several years ago to
2 attached buildings. (both vented with cora ridge and doing fine)
The Geodesic Dome is nasty.....There is no ventilation in the traingle
shapes... . it was insulated with standard batt insulation and sheetrocked
interior......No place for the water vapor to vent.....
The owner knows it, I really cannot fix the problem other than re-roof
it.....
What a job......
All the cells are enclosed.......
What can you do?
any ideas welcome....

Foam roofing is a way to go. If there is no moisture damage he
probably doesnt need it.

Spray applied polyurethane foam roofing is good stuff if the building
is designed to deal with the moisture from inside the building. It
totally changes the look of the building, and maybe that's wanted or
not. Whether the additional expense and change in appearance is
desired is up to the owner.

The big caveat is that moisture from inside the building will condense
inside the batt insulation or, more likely, right on the plywood
sheathing. If extreme care was taken to seal all gaps and
penetrations, and a vapor barrier paint was applied to prevent
moisture from migrating into the insulation space, there'd be a fair
chance that it would have good longevity.

Re: Re-Roofing a Geodesic Dome
Would installing an air exchanger help?

JL:
If you are primarily looking for exterior ventiliation solutions on the new
re-roof, here are some things to
think on. I have seen wind turbines on domes, though the look flattering.
Solar chimneys would also
help with the venting and cooling. There are as well various passive,
thermostatically-triggered panel openers
which are used in the greenhouse industry which may be of interest to you
directly or as a modficable base. If
someone hasn't already adapted them to geodesics, it would be surprising.
There may be a combination
dormer/light pipe and, if not, it wouldn't be hard to vent some available
light pipes which would also, of course,
help with illumination; lastly, think of flat, shielded fan units.
