Bird proofing proposed steel roof

[HBush]

Can anyone tell me? I have a quote to re-roof an existing asbestos roofed brick shed with steel sheeting. The asbestos sheeting was pointed with cement where it contacted the brick walls, to stop birds entering.

What can be done to stop the birds coming in underneath when box profile sheeting is the roofing material?

You can get foam fillers to match the steel sheet profile. Usually supplied by steel sheet stockist.

Make sure they mastic them in well so they don't easily get pulled out by birds or rats.

Thank you very much solo and designndetail. That was so helpful!
I shall ask for bird exclusion fillers to be masticed in place, to be added to my quote.

Is Silly foam not bird proof and too messy to install

 

[HBush]

The bulgy expandible builders foam? It degrades when light hits it, but good idea otherwise.

Birds will peck it to bits . Tried it .
Then bits of foam dropping everywhere

You can get sheet that is cut to the profile of the underside of the sheet. This could then be screwed to the brick walls. Would be dearer but better long term.

All to no avail it would seem! The contractor says that non con sheeting should not be blocked against birds as it would cause corrosion. Maybe I should use fibre cement roofing sheets after all.

Your contractor is correct, in a fashion! Anti condensation sheets require ventilation at both the eaves and ridge to work properly otherwise any moisture that collects in the fleece lining will not evaporate and just drip. Fibre cement would be the better option is you want to make the building bird proof and to be honest should be cheaper than box profile with anti con.

Thank you for the advice Nose Abit. The solar contractors want me to fit steel sheets, and fibre cement has some big advantages in terms of condensation and maintenance. I think I am looking for the Third Way!

40mm composite panel? Probably the most expensive option, but no condensation and will keep the solar guys happy.

Thank you very much Nose Abit. I just contacted Steadmans. Price wise is about £15/sq. m more expensive than non con. I think the brick walls and floor would be pretty moist in winter too, but easier not to let things touch the wall than keep away from drips. Steadmans say I would need 60mm to prevent condensation.

Best go with what Steadmans say and you are half way to having an insulated building! Will make a big difference inside.
