Types of roofing for a deck/pagoda

[baileyboy]

Hi All,
I'm not entirely sure where to put this. As its for a deck but also probably relevant to pagodas too.

Anyway, I've built a deck (5x7) and is in the process of putting a roof over it. Initially I'm going put colour bond (standard corrugated sheets) on rafters because I like the look of having extra head space. The rafters at approx 2.4m and pitch is approx 18 degrees. Then my brother visited me and suggest I put a ceiling. I don't like the look of the ceiling but he said it will be much cooler. Or at least put insulation. I trawled through a few houses for sale online and I hardly see any houses with insulation. So I would like to hear what the experts on this forum have to say. Maybe start a discussion on pros vs cons.

The options are:

1. metal sheets (no insulation) - cheapest, more rustic look

2. metal sheets (with insulation) - IMHO looks terrible

3. Insulated sheets (bondoor type) - apparently it cost an arm and a leg

4. Ceiling - lot more work, reduced headroom.

Go the insulated panel.
Looks the best and keeps the most heat out.
It costs about $80.00 sqm
Remember that you dont need rafters and battens.

Lined patios look very 1980's
Metal Roofing with foil insulation looks like a shed not a place to relax. Even though my foil insulated shed is very relaxing:U.

Use a product that is white to the sky and it will reflect most radiant heat anyway, .e.g zincalum or light coloured colorbond or light coloured (not clear) polycarbonate/laserlight. Use google maps or nearmap to check out houses you know have roofs like the one you want. If they are basically white from above IMO you are wasting money on insulation for heat on an open air structure. Insulation to reduce condensation is another matter though.

Definately go insulated panels, nothing better.

Yep go the solar span type of insulated panels. Putting a ceiling in is a very labour intensive exercise which requires battens/sheeting/setting/sanding/painting. By the time you do all that the cost is virtually the same as just going the panel straight up and forget about the maintenance side. You would need to go to 100 mm panel to span 5 mt though I think. Last one I had done was $ 100 m2 + install. Only downside is no recessed lighting but I like surface mounted lights anyway

The insulated panels and large spans certainly look great from underneath. Can it be walked on if necessary?

Yes, you can walk on it.
Talk to the supplier as to span and thickness, and for your lights run your conduits in the receiver channel and in the joins of the panels so they are not seen. Simply scrape out a little styrofoam to accomodate the conduit.

Yep they do look good. Fully trafficable.
