You hand to spend money 💰 on it

How as the rainwater hits the roof on top, the deck stays water free ;)

+GenuinePluko ahhh... I missed that part

Taking the easy way to an enclosed deck aren't ya?

The are 2x6in (well actually slightly less, due to the metric sizes we have for lumber here in Ireland).

Info I've seen on the web suggests that Polycarbonate is very strong, so my guess is a 5-wall sheet like I used can probably handle a lot of snow. But you'd need to check the technical specs with the supplier to be sure. Also you need to make sure the sheets are well supported underneath, to avoid them bending under the weight. Of course the overall roof timber structure has to be strong enough to take all the weight too. I suggest you get the advice of a roofer or carpenter. Re wind-lift you can secure the sheets with bolt-through glazing 'buttons' near any vulnerable edge.

I can’t give any insight about the snow, but I live in coastal NC (frequent hurricanes). My in-laws installed a material (that looks similar to that) on their (lattice-roofed) pergola-styled outdoor structure 25+ years ago and have never had a problem. They live about 45-60 minutes inland and in a large open area surrounded by fields where they have constant winds, down-drafts, and frequent (inland) hurricanes. Hope that helps.

Ok

@@fardinger many thanks

I've only just seen this video, but in answer to your question, there is a company in the UK called Cunningham Covers who can produce the side covers for your Pergola. I hope this is still relevant for you.

+Cartha Byrne - Hi, Yes everything has survived the storms just fine. No leaks in roof. We had christmas dinner on the deck (with the help of a gas heater). Got the polycarbonate from polycarbdirect.co.uk. Can't remember the exact pricing, but it was the cheapest I could find at the time. Delivery was fairly slow, but I guess you get what you pay for! Re the roof joins, we were careful to space the timbers to exactly match the standard roof sheet widths (including expansion space of 10mm). The rag gasket was stapled along the top of the timber & the sheet edges laid on top of that. The aluminium glazing bar was placed on top (across the 2 sheet edges) and screwed through, down onto the timber. This effectively clamped the sheets in place. Also I have a row of glazing 'buttons' along the lower edge of the roof sheets, about a foot back from the edge. These screw through the sheets into noggins below. This is to prevent any wind-lift at the lower (unsupported) edge. We had to get up on top of the roof to place the sheets & fix in the screws. We put in some temporary timber bracing under the roof timbers to support the weight & we used long wide planks on top of the sheets to spread the weight. I highly recommend you do this project. We have gotten loads of use out of this deck.

Its nearly 2 years ago now, so hard to remember exactly. I think between 3K & 4K Euro, excluding the side covers.

Its a few years ago since I did that job, so my memory of the costs is a bit hazy. I think the side covers were around €1,500.

The posts are 150mm x 150mm in larch. I chose this size because they are nice & chunky looking, and also of course plenty of strength to support the roof. I got them from a saw-mill in Ballyporeen, County Tipperary. But other saw mills might have them also. Larch has good water resistance.

The roof sheets have held up very well. No discoloration. There's about 8 inches at the front edge, which has wicked water into the interior of the sheets. That's a bit unsightly, but I doubt there's anything I can do about it. Otherwise, no dirt is inside the sheets.

Its funny you should mention snow. We had a rare snowfall event here last month. There was 30cm (1 foot) of snow on the roof. It's been more than 30 years since we had that much snow in this part of the world. The roof handled the weight no problem.

Its a manufactured tile of some kind (not natural slate). I'm not sure exactly what the brand name is. They are very common on houses here in Ireland.

Several years ago now. Can't recall. Might have been Access Plastics in Dublin.

+rakesh baden - I got the materials from my local hardware / building-supply store. The staff in these stores are a good source of advice about the correct timber size, joist hangers, screws etc. You should discuss the project with them. Best of luck with it.

+26souljah - The roof of our house overlaps the edge of the polycarbonate sheets by about 50cm. So we didn't need to pay much attention to making the sheet edge watertight. As you may have seen in the video, the sheets sit on top of a beam that's attached to the wall. We attached a second timber plank above this main beam, with just enough of a gap to fit the sheet. So the sheet slots in between these 2 pieces of timber, which holds it securely.

+fardinger thank you very much.. For getting back to me.. That's exactly what I'll be doing!! Still can't stop watching what you have achieved!!! 👍🏻

The covers are still in very good condition. No obvious deterioration. One or two slight marks on the transparent panels, where they got overheated by the sun while rolled-up, and stuck together. But you'd barely notice the marks.

Winter temps here are 5 to 10 degrees C in the daytime, and yes we use a gas heater in the winter. Plenty of light comes in through the roof. My plants thrive in there. Also there's plenty of ventilation coming in under the floor & at the front edge of the roof.

Great! thanks a lot for the quick response. I live in the USA and it does get colder over. I also found an alternative to your covers Eze Breeze windows but they are expensive for me . Anyways thanks a lot for sharing and again this really inspired me to duplicate ..

🤣🤣🤣🤣 are you serious ?

Would you stop

Yes I did

@@fardinger Many thanks. Just starting mine this weekend ! Great video, thanks a million for sharing

One end of each noggin was screwed straight through the roof joist (which was then hidden by the next noggin). The other end of the noggin was diagonal screwed, which unfortunately left screw heads visible near one end of each noggin.

Oh, great , thank you very much for your kind and informative answer :-)

My span is similar to yours. The joists are doing well here, after several years. No obvious sagging. I think the cross-braces between the joists are an important factor, that lends support to the whole structure.

thats great thanks, I think I'll go for 2x6's then. I may bolt steel plates to the sides of them in future years just in case. Wickes do one that 2.5m long

The side covers have stood up to hurricane force winds, and have not been damaged in any way. Along the bottom edge of each cover, there's a thin plank of wood inside the PVC. This sits squarely against the flat side of the deck (just below floor level). This helps to keep the cover from sagging inwards in the wind. Also in winter, I screw this plank into the floor timbers (there's no need to open the covers in winter) which supports the covers against strong winds.

fardinger many thanks for your reply, it's been very helpful

The timber is all holding up well. No visible rot. The roofing has remained water tight after 5 years.
