repairing holes on perspex roof sheets

anez · 09-10-2010 07:02PM #1

I just notices small holes appearing on perspex roof sheets on a farm shed. (The shed is about 25 years old) I was wondering how I could repair the holes, some are quite small but others are much bigger, has anyone any suggestions what I can do as it would be a massive job to replace them, thanks Anez

I'm afraid anez that it sounds that the sun's UV rays have made your clear sheets brittle with time and caused them to crack and break.

I bet if you went up on the roof or poked them from below they would just fall apart:(

The sheets' transparency are prob compromised now too anyways too.

It shouldn't be that big of a job to get replacements and fit them, especially if the sheets are flat ie.it's not a round hay shed roof

You know that black bitumen paint you use to seal roofs outside? Well use a piece of cotton, paint it both sides, paint the area around the hole and stick the impregnated cloth to it. Paint over it again. Job done.

gotta agree with muckit.

They only have a fixed service life.

you can patch them, but things are only gonna get worse. the only real fix is to replace them.

sorry

The easiest way is to try and get sheeting with the same profile and just lap it over it, no need to replace the old. Saves pulling nails/screws in the steel sheets. That's what I'd do anyway if possible.

That's just a short term fix and will cost you double in the long run. If you put on one sheet on top of the other, you will have green scum grow between the sheets from the condensation. Also, by not replacing the sheets properly you risk a drip getting to roof timbers which will eventually rot them. Best bet is to pull the nails and replace the sheet properly. A little bit extra saves an awful lot in the long run.

Replace them. Even if you patch the holes now, there will probably be more holes in another year.

Thanks for all the advice, I will try to repair them for now and fingers crossed I will replace the sheets next year, Anez.
