roof question
 

I live in Phoenix AZ and I plan to install photocells on roof to help
environment.
My house is 11 years old with original ceramic tile roof. I know ceramic
tiles have very long life and problem is the limited life of the underlay.
Before the tiles are ripped out I would like to know what the life of the
underlay is for the hot desert. Some have said ten years max.
How do I assess the underlay life? Should I have the underlay replaced
during the photocell install?
Thank you,
Seamus J. Wilson

Why photocells? Do you need to know when the Sun is up?

While Phoenix is a good location for solar power, be advised you will not
generate as much energy as it took to manufacture the things in the first
place. A better environmental solution is to outlaw photovoltaic cells.

In your neighborhood, solar water heating is a plus.

They put ceramic tiles on roofs in Phoenix?

I can believe it. I'd quite like to see something for all these
"green" solutions - PV panels, CFLs, wind turbines (the "home sized"
stuff, not commercial) etc. analyzing the real "cost" (materials,
processing, manufacture, shipping, disposal etc.) - I suspect a lot of
them do far more harm than good.

Heatpumps seem to genuinely work, so does solar heating, so does properly
insulating buildings - but I think there's probably a lot of horsecrap
technology out there, too. Very difficult to get past the political spin
to the truth though (and to recognise the truth is when you're told it :-)

cheers

*When I worked in Southern California I saw a lot of tile roofs be installed
over hot mopped tar and paper. I inquired about the longevity of this type
of installation. I was told 50 years if the tiles are not disturbed.

I think that you should get the roof evaluated prior to the installation of
photovoltaic panels. It would be a shame to have to remove them in a few
years to replace the roof.

As others have mentioned I also question how much good to the environment
you will be doing. You certainly won't see a payback on this installation
for many years. A solar water heater makes more economic sense.
