rusted galvanise roof

tomieen jones

Is it worth painting a rusted galvanise barn roof or just replace the sheets? About 1000 to paint I was quoted! Its a fairly big barn 4 columns and a cubicle shed adjoined! Its red at the moment but that's rust! It was never painted and built in 1975

I'd be thinking its surface rust , that old sheeting is mighty stuff compared to the stuff today, I took down a round roof hay barn the sheeting was in the late 60s was rusty looking from outside but solid to walk on and underneath looked 100%

1000 sounds an awful lot to paint it . Powerwash roof buy paint and put on yourself with a soft yard brush and bucket
I would imagine a few hundred should cover it
A five gallon drum of paint is around 90 euro and would cover a lot of area.
If doing it yourself pick a dry day and be very careful if there are skylights on the roof one foot wrong and you would go through them like paper and be careful on the ladder going on and off apart from that its a simple enough job.

If he's priming it before painting it then it's about right. As said already that older sheeting was bullet proof stuff compared to the stuff nowadays.

Its not a job id do myself but I do believe it would be very good quality sheeting and only surface rust! But can surface rust be painted over or should it be removed? If so how best remove it?

A friend of mine repainted his shed roof last summer. He got a wire brush head that fits on a drill and adapted it to fit on his petrol strimmer. I drove by his place and seen him up strimming the roof. I called in and watched him. It was a quick way of getting the heaviest of the rust off. Everyone that seen it thought the man had lost it.

If we get a few roasting hit days this summer, pressure wash off the rust. Something like a 3000 psi washer. Use minimal amount of thinners, no more than 10%. Mix it with a plaster whisk I an electric drill and sweep it on. 30 foot wide shed plus lean-to , four bays long will take about 30 gallons of paint.

You can buy a special roller that matches the corrugates. Any decent coop should have them.

Personally think Professional job is well worth it and will last 10yr plus.

Do it yourself and you'd be lucky if it lasts 5yrs.

I would agree ! I'll get someone reputable and maybe sprayed on would be better?

Yes you should go ahead and paint. A couple of years ago I painted a roof put on in mid 1960's was very rusty but when it was powerwashed and painted it looks fine the sheeting was still sound.

The are terrible fcukin things. As you brush up against the edge of a sheet it will start to wear. After an hour or two lumps with fall out of it. Get the corrugated woolly brush head instead. About 23 quid but far better. Did the hay shed last year myself.
