How to Install Corrugated Polycarbonate Roofing _ Mitre 10 Easy As DIY

If you've got a pago attached to your house , then you might want to give yourself some extra shelter and protection from the weather .

Simply by installing some corrugated PV C roofing , it's not a difficult job and we'll give you an outdoor area that's a lot more usable before we get stuck in .

You need to be mindful of a few things .

Firstly , building regulations only permit you to put a roof that's 20 square meters or under onto your pago .

So make sure you measure it up properly and are under the limit .

You'll need a minimum of a five degree fall .

Plus it's always a good idea to check with your council for any updated building regulations just in case righty eight time to miser up for our sheet .

So I've got a length of 21 40 .

Now , I'm gonna allow 60 M overhang also .

So that makes that 2.2 .

So you can go down and cut them .

Now , if you're unsure if your roof is actually parallel , you might want to measure and cut each one of these sheets individually .

So I've just got a mark 2.2 with a vivid on our sheet on , on either side , we just rule a line one side or the other .

Now , there's a couple of different ways we can actually cut .

This one is using a fine tooth hand saw , cutting on a nice low angle or you can just use a set of tin snaps .

Now , just do the same for all the rest .

Now , our roofing just sits hard up against our weatherboard .

Now , I'm not gonna leave it like that because otherwise water's just gonna get down through the back .

So , what I've had made up is an apron flashing .

Now , the way an apron flashing works is it tucks in underneath between these two weatherboards .

It's gonna give us a nice weather tight seal .

So in order to get that underneath , I'm gonna have to open that join up to slip it in .

Now , I want to protrude up at least 40 millimeters .

Now , I've had this apron flashing custom made to the right color and length by placing an order of the guys in the trade department that might attend .

Now , one of our best friends you can use for this particular job is using the mighty handy bar that's just gonna get underneath between those two boards and wedge them open gently .

We only just want to take our time .

We don't want to crack these weatherboards .

It's only enough just to get the blade of our sabers sore underneath so we can cut the nails .

Yeah .

Ok .

I've just about tucked in my apron flashing in behind that weatherboard .

So I'll just crank that up a little bit further right now .

That's looking pretty good .

All I need to do now is slip my roofing in underneath and then once I put a sheet on , I'll come back and nail through the top weatherboard and through my flashing .

So then I don't have to climb back up on the roof later on .

Now , there's just a couple of bits of information you should know before you go screwing down your sheets .

Now , these great screws here are actually got a cutting edge at the top of them .

So we don't actually need to pre drill them .

The shank size is about six millimeters .

We actually need a 10 mil hole to go through our roofing to allow for expansion and contraction .

So these little puppies here will do all the drilling for us .

So there's no need for us to get a drill bit out .

Now , one other thing , I've put my cut into my sheet underneath the flashing , so we don't see any rough points and I've also made sure that I'm 60 m hanging over the edge .

Now , just one other thing I'm just gonna double check is to make sure that my roofing has got to be parallel with all my rafters because that's what you're gonna see from underneath .

I can't trust the old house is gonna be 90 degrees .

So I'm just gonna make sure that the edge of the roof is parallel with the side of our rafter .

So I got 60 millimeters there and they could come over just to tad and that's 60 millimeters here that look great .

One other little tip too .

You just want to make sure your screws are all nice and straight .

So we've just got to mark every second one of these ridge lines .

Now , I'm not actually going to fix the first ridge there because we're gonna have the overlap of the sheet that's gonna go through that one .

So we'll just start the second one in and you only want to just drill that down just enough .

So it's not pushing the sheet down too far .

Now , when it comes to fixing into our Pearland , you only actually need to put the screws every third ridge , but just to make it look nice and tidy and everything in line .

I'm just going to follow the same distance as the ones down the bottom now because I've got an internal corner here .

I'm also going to have to put another apron flashing down this line because I've got a corner box here and a flat box in the middle .

I've got all these different lines just to make it easy for myself .

When I put the apron flashing on , I've just ripped a couple of packers and I've just silicon them to the weather boards and that's just gonna take out all those different lines and all that .

All I'm gonna do is place the apron flashing hard on top of that and then I'll have a piece of timber that sits on top of that and it keeps it all nice and water tight .

Now , I'm just gonna fix this apron flashing in place using these 30 mil galvanized clouts .

Now , I'll just do the same along the rest of the line .

Ok .

I'm just about ready to fix down my little timber head flashing .

Then all I have to do is screw down our apron flashing through our roofing into our Pelin .

Now , just a wee little note , the type of screws that we're gonna use that go through our steel flashing are not the same type of screws that we use for our PV C sheeting .

These are just the standard roofing screw .

It doesn't have the pre drilling sort of function on the end of it .

Now , when you're laying these sheets , you just want to make sure that you're only doing one overlap onto the previous sheet .

Now , we're just gonna make sure that we're 60 mil from the front face , we're in line with the previous sheet and then once again , we fix exactly the same as we did the other sheet .

Now , just don't forget to nail off your weather , the board through the flashing as you work your way along .

Now , another thing you also have to do as you work your way along is just pushing the soft edge into the profile of the corrugate .

You don't want to jump up and do this later .

Sweet ass .

Now , I've got a half sheet here .

I cut that down using my tin snaps and we just screw that down .

Same as we always have as per council regulations .

The next thing you'll need to do is install guttering , check it out a great result and a pretty simple way to create some extra shelter and give yourself an outdoor area .

It's a lot more usable .
