Thanks for posting this video. Well, regardless of some comments on here I found it very useful and clear to understand how everything fits together and the various parts and accessories I need to do the job. I also found the comments people made (good and bad) were useful tips about issues you come across. Thanks to all.

Can you add a rain gutter to polycarbonate pergola roof?

Can we add sides to this patio cover?

What program is this animation created in?

How do you place the wall flashing along the back?

Where can I get this in the U.S?

Do you have a distributor or installers her in the US?

I'm interested in installing this system in the US but I see you are a British company. Any suppliers in the US that I could purchase the channel kit from? Thanks.

Para po be etu sa flat rooof?

Where can I buy this floating drill to screw down the sheets?

how far apart do the intermediary bars have to be ? I am building a 5 mtr span and intended puting 3 intermediary supports at 125 cm apart. any one know ?

Yes I give thanks

You really need to add some sound to this, KZfaq has a library if royalty free music you can use.

It is most important to leave an expansion gap between the sheets of at least 10mm. Its best to remove protective film before the top capping goes on. Also don't overtighten the fixings. A slick presentation but not of much value.

fittings are just tooooo expensive

This is really misleading, it's actually wrong. You need to fully install each section of roofing at a time otherwise there will be loads of bits you cannot reach without climbing on the roof, for example how are you supposed to fit the flash band once the roofing sheets are installed? Rubbish!
