Pergola of sorts

[sh4d0w]

So... Before i potentially waste my time (and money); is this a viable option?

I am in the process of a landscaping project at home and i have created a space that we want under cover, i plan on using corrugated bitumen sheets as the roof so nice and light.

I have put in new fence posts all 3FT deep into clay and 400mm-450mm dia holes full of 5/1 concrete.

Can i fasten the upright supports to the fence posts and create my framework up top OR should i not and put in some dedicated timber posts to support the pergola?

Concrete posts can be surprisingly easy to snap if you get enough leverage. I had to move one, it was only a couple of years old and concreted in. It snapped near the base very easily after a push.

You'd have a couple of metres of leverage. Someone casually leaning on it could snap it.

There are fittings for hanging from concrete posts, you don't want to drill them. But they're intended for bits and bobs like lights and baskets, not structures.

Don't know about that.
I've covered my alley 15 years ago and bolted the wooden structure 2.4m high to the existing 2 foot concrete posts.
No movement whatsoever.

corrugated bitumen sheets?

Call it what you like but it won't be a pergola.

Ok, so i want a covered structure to cover my outdoor kitchen and hot tub.

Pergolas to their name seem pretty pointless to me....
Hey Wife, lets go and sit on the patio with a nice glass of wine under them timbers, in the rain.... or blistering sun where we will be greatly protected from the elements.

Its more like a Gazebo if we want to split hairs.

Bitumen sheets were my choice due to strength and durability plus weight.

Poly sheets will create a greenhouse until the roof ends up green, then we have to clean it....

OSB Deck and Felt - Heavy and not fit for my aforementioned plans on the fence posts...

Pitched roof and Shingles, heavy and pointless.

Give me some alternatives, im all ears.

Was done in 2 stages, 2 years apart, using recycled wood for the brown part, hence the difference in the 2 structures.
I meant to dismantle the brown bit and continue the other one with the better slope, but things get in the way...

If you want a more aesthetic option, you can use composite shingles. It mimics the look of natural shingles, but is lightweight and durable. It is, of course, more expensive
