I've got an iron roof that's really due for replacement. We have a quote of about $12K to replace it with color steel. Can anyone take a guess what it might cost to put modern tiles on? Not the heavy concrete ones, the metal ones with the coating on them. Can tiles go over the top of the old iron roof?

Also interested in advantages and disadvantages of steel vs tiles.

We just had a quote to replace out old concrete tiles with metal tiles or long run colour steel. The price difference was about $100 (total quote was around the $18k mark)

Interesting, thanks. Have you decided what to do, or do you have pros and cons of each?

It would depend on the look of the building I would have thought. Some of those metal profile tiles look pretty horrible and cheap, and they are 'imitating' a conventional tile. Plus older ones I have seen tend to accurate a lot of lichen in the crevices on then due to their size and shape. There are a whole lot of different long run roofing options and profiles to choose. But if your house is just a bog standard design, then the cheapest option maybe what you are looking for. Although I would have though that long run profiles would be cheaper, as they should use less materioal, and should be a lot faster to install.

Also remember that if you are changing roofing type, eg moving from longrun to a tiled roof , you must get a building consentwith your TA. This could add a lot to the costs, as you need drawings and consent fees etc.
 However if you have changing like for like (eg longrun coro, with longrun coro) then you may not need one. Check with your council on this, as you may if you change the profile.

Ah yes, building consent. No way do I want to get into that minefield, thanks for pointing that out.

I think that may decide it for you :) You definitely don't want to change roof type, not get a consent when you should have, and then try to sell you house, and the potential buyer then discovers the reroof needed a consent.

Replacing with long run is the easiest and cheapest solution.

Tiles look nice but easily dent if you don't walk on the toe of each tile. The tiles are actually coloursteel sheet formed to look like tiles (if you're looking at what I think you are).

In terms of durability and weathertightness there is little difference between tiles and long run.

I have built several houses and used long run colorsteel corrugated iron, pressed colorsteel tiles and pressed steel decramastic tiles.  My current house was built in 1975 and has concrete Monier tiles.  Every roof type has its advantages and disadvantages.  The least hassle and strongest has to be longrun colorsteel corrugated.  Great for low weight, storm resistant, but noisy in the rain which some folk actually like.  I would avoid pressed steel tiles, they are a mission to walk on and need just as much moss treatment as real clay or concrete tiles, but lighter and looks like a traditional tile roof.  Going to concrete or clay tiles is not an option as the roof would likely need to be retrussed.  Pressed steel tiles will need all new purlins at the correct spacing.  Even the corrugated long run will need some of the purlins replacing most likely, but its the cheapest option and in NZ fairly typical.  Plus you can walk on it.

You can also now get a deeper profiled corrugated steel profile, which I believe can span further / larger spaced purlins, and I would think it maybe able to hold more weight. Probably more expensive though, as it would use more material. If you don't want to hear rain, you could always line the roof with ply, then install a free draining padding material for condensation and muffling. However this would need a consent, detail drawings, and expensive, but some people want a quiet roof.

Thanks guys, I appreciate the thoughts. I don't much care about the noise. I have close to a foot of insulation in my ceiling, I don't hear rain unless it hits the bedroom window.

In case anyone wonders why I have so much insulation: I had loose fill wool insulation blown in, worked well but compacted. I then put some left over under floor insulation in over the top of that in some places. Next I put in pink batts throughout. I had some left over so some places have double layers of batts. I'm happy with overkill :) It's an old house, every little bit helps, it's still not near as good as a new house but much much better than when I bought it, uninsulated.

Please don't get the metal tiles. I hate them with a passion as a plumber. Their shape makes it far more difficult to reliably run pipes, flues ect through the roof. Easily dented as said earlier. And yes dents can cause them to leak depending on what part is dented. Also some installers don't remove the old roof first. They just attach wooden strips to the old iron. Then fasten the metal tiles to these strips. Makes it even more difficult to run new pipes through the roof - multiple layers. And my mum, who is a civil defence volunteer, said they didn't handle the Hobsonville tornado as well as other roof types.

In that case the old purlins would probably have to be replaced for either style. With a corro roof the long run would use the existing purlins but pressed tiles would need new timber.

Wouldn't tiles make it easier to flash as with corro don't you have to go up to the ridge flashing now?

Yes best trade practice is to dry pan up to the ridging so the penetration doesn't cause water to backup.

Avoid Monier.

Friends had tile, they got a quote as loads of them were damaged and ended up with iron instead as it was quite a bit cheaper.

Dont get the metal tiles.

Have had no end of problems with them leaking in sideways rain, They look messy where they fold the ends over going into spouting etc, and many of them have had the nails on the face work loose then the tiles start to bang in the wind.
