Noisy laser lite

[Gumby]

I recently had a new roof put over the back deck. We used the normal Laser lite roofing but it makes a lot of noise all day as it expands and shrinks in the sun. I had this stuff up there before and it was only about 7 years old. it didn't carry on like the new stuff does.

It was attached using those self drilling screws which have a cutter just under the screw head. They cut a larger hole than the screw itself so it isn't that the holes need to be bigger. There is plenty of room around the hole for expansion. I was thinking that maybe it needs to be tightened down a bit more. Any thoughts before I get up there and have a play.

Laser lite make a noise stop perlin tape to prevent this - sounds like pulling it up, taping the rafters and laying it again

I am still deciding on whether or not to put laserlite up for this very reason.

I understand that you can get some tape to go under the laserlite, on top of the rafters (sorry, don't know if that's the correct term) which is kind of padded, and helps reduce the noise.

(whoops looks like Eastie got in before me!)

Hey BinJ

your icon looks like its got tackle !!!:eek:

[Gumby]

oh well, it's better than the noise. I just can't understand why the last lot didn't do it. Well, i didn't notice it as much anyway. :confused: I don't think there was tape up there, in fact almost certain.

Thanks guys, I'll check it out, try a small section and see if it works.

Our LL at home is quiet but My BIl's makes a terrible noise.
Wonder why that is?

I think he used the tape too.

Mine fgaces north so it gets all the sun. Even when the sun goes in behind a cloud the bloody stuff starts to shring straight away. When the sun pops out again, more creaking.

If yours is at the back Al, that would face south from memory. I wonder if that has something to do with it. :confused:

Ive got a carport out the front that faces north/south, and a carport at the side that is east/west,(Im talking which way the roof faces) neither makes any noise.

Are the screws tight?
I tend to over tighten all my screws.

Al :confused:

[Gumby]

Are the screws tight?


Al :confused:

I don't think that they are tight at all. I could give them a couple of turns which would push the rubber seal onto them a bit more. I suppose it's worth a try.

[ozwinner]

I usually tighten until the ridge goes nearly flat, the undo a couple of turns.

Hey, Im a ham fisted brickie what else do you expect?

This may be a dumb thing to say but when I put up the L/Lite roof on my spa room, the guy said to me, "Make sure it all goes up with the correct side facing up". On closer inspection of the lable on each sheet it tells you that this is the side that faces up. He said he gets a lot of people coming back with noise complaints and most of the time they have put them up any which way.

[ozwinner]

I put on one sheet the wrong way up, it went brittle and fell apart.

[Gumby]

Thanks for the tip Savage. I checked and found they all went the correct way up so that's not it. I'll tighten a couple of sheets and see if it helps.

Gumby,
the screws need to be tight enough that the rubber seals are slightly compressed. Tha't slightly compressed, not flattened out and certainly not loose either.

The noise is more than likely coming from a heap of freo dorcker supporters creeping about looking for a place to stay when the perennial losers they call a football team make the GF.......in their dreams and no there is not a misprint there.
