Roof repair

[nick...]

I’ve got a plastic coated tin shed roof,box profile tin I think it’s called, that is rusting at the point where It touches a steel girder.the sheeting is unavailable to replace so thinking about getting some fibre glass matting and putting that over the top.has anyone any experience doing this and if so did it work ok.

You can’t get the tin to replace it?

I’m surprised - Thomas Panels and Profiles can make anything in my experience.

It’s just about a foot from the end that’s getting wholey.the sheets are about 10 metres long and woukd need to cover 15/18metre width

Why is the tin touching the steel girders, do you mean the Perlins

A picture would be useful if you can safely get one @nick...

No it comes over an rsj on front of shed.there was a Alvin blanch continuous flow drier in there in the past and I think heat and steam have done the damage.

Can you get a layer of builders DPM in between? I bet there's a bit left from your project & treat it with Waxoil?

Have considered sliding flat galvanised tin under the sheets but fibre glass would be easier for me to do by myself without help.

Steel & steel may cause more issues owing to condensation in spring & autmn and associated capilliary action.......Hence my suggestion of a plastic substrate. Food for thought?

what about using the the roof repair paint with the fiberglass fibers through it , was planning doing a small repair with it myself

 

[Blackleg]

Try a small bit first, the fibreglass resin melted the plastisol type coating on a sheet I tried

Ah, Nick that's (na)ckered, BER or whatever else you'd like to call a worn out roof! A few sheets in the colour of your choice would be my way forward. Whatever you do you'll have to come back to it sooner so why waste time now but spend time & some £'s and fix it properly. Only advantage you will have is access to the eaves of the building at the top of the pitch to doctor them prior to the repair.
I'd bolt 75mm x 50mm treated timber to whatever is under as this will space it away from the steel that's caused all the grief and use the usual fixings for timber and coloured caps. Presto.....Fixed for a long time and will see you out.

IMO no amount of jiggery-bodgery will let you turn your back as it will still be rusting away underneath!

https://www.acbacon.co.uk/ Fab co and local to you and will supply the sheets & fixings and if you really need a quote to fix so you don't have to worry. The did me proud and G-father had put up my original two 1960's sheds in the past.

take off the sheets and cut off the bad bit , they will sell well at a local sale and buy some new

 

[KennyO]

Could you slide some plygene (what they make gutterliner from) from H D Sharman up under the sheets?

Might buy you a few more years.

I would probably bite the bullet and replace sheets though.

Don’t forget to sell the holes to Kev and Pete!
