Colorbond, Metal Sheet Roofing By Bluescope Worth It?

[tangcoral]

I have searched and seen a few post discussing metal sheets for roofing but I have a question that hasnt been discussed.

I have decided to replace our 30+ years old light weight synthetic tiled roof which most likely contains asbestos and cement.

The frame work and truss are made of small wood beams.

I decided on metal sheets because it would probably be the lightest in weight and lessen the aggravation to the old would frame.

I was introduced to Lysaght which is produced by Bluescope, those of you from Australia would be more familiar with this company.

They also have colorbond but it cost a bit more as they are prepainted to 20+ color choices.

I was qouted from Bluescope that the lysaght metal sheeting would cost me 300baht a sqm while colorboond was about 430 baht a sqm.

That would be an extra 18,000baht for my 140sqm roof

Supposedly Bluescope steel are suppose to be of high quality thus the high cost.

No doubt one shouldnt skimp on the roof material as it plays an integral role in your home.

However my question is..there are many other low cost companies that manufacturer galvanized steel coated with zinc, but will I be kicking myself later if the savings of nearly half the material cost to a cheaper brand?

I'm guessing here cause I havent received any quotes but the lower cost metal sheets cost 150 baht or less?

So thats the cost difeerence of 42,000baht vs 21,000baht

Plus I would most likely have the people at bluescope do the installation which will cost me an arm and a leg.

I'm wondering how much better is bluescope than others. I have heard from others that bluescope would probably last a minimum of 30 years or more

Would the cheaper product last me less than 10 yrs? Are the quality of metal sheets that poor for me to steer clear and go for the best?

Any input or experiences much appreciated.

I just did a roof with galvanized steel, looks just like the stuff in this PDF

http://www.metalroofingsource.com/Absolute%20Roofing%20Instructions.pdf

It comes in two weights, if memory serves 27 and 33 mil, the heavier cost me 100B/ linear meter. With overlap I think the coverage is 78cm per sheet in width. Can be cut to your needed length, maybe up to 9 meters.

The price for the same stuff at Global House was 160B at the time. That's a big difference. Also the screws vary from 1B/per (Global) to 3B/per where I got the roofing.

It goes on really easily, but your average local roofer will want to put the screws in the peaks rather than the flat, contrary to manufacturers instructions. Flashing, drip edge, eaves etc are likely make do, I saw none stocked.

I put a dab of silicone on every screw hole for insurance. This stuff is supposed to last, but I am going to paint it anyway.

good luck

Do you really need to replace your roof? Our village here in Bangkok was built in 1974 and none of the over 200 homes have had to replace cement/asbestos roof tiles unless as part of a total new house.

Be prepared for the cost of sound insulation when using metal roof sheets.

Can I ask where you purchased it? Do they only have it in silver? I have see it used on a lot of commercial buildings in CM in both red and a dark blue/green which looks quite nice.

Cheers.

Sorry I left out the specifics, I am doing a whole house renovation which included installing insulation of fiberglass and under tile reflective foil.

I decided to replace the roof since I am up there anyways.

As of now there are no leaks but there are a few damaged pieces that needed to be replaced and minor cracks here and there but nothing warranting a replacement..

Asbestos just didnt sit well with me especially having a toddler and possibly another one on the way even though asbestos is only dangerous when its airborne which in my case tiny if not any.

I am just wondering if any of these other cheaper brand metal sheeting will be okay.

Ive seen galvanized only

I got it at one of the village hardware stores, they have all kinds of goodies, and what they don't have, the guy next door does (Phu Wiang).

There are two major kinds of screws with rubber washers in use, one has threads all the way, others threads stop an inch or so from the head. I would imagine for use in the peaks. Global House has both kinds and the shorter TEK screws used to bind two overlapping peaks.

I also used insulation from Home Pro, R-3?, the highest they had at 450B/60cmX~4M roll, fiberglass totally wrapped in a foil layer (light green plastic package). I made my own drip edge and such from colored "square wave" style roofing.

No leaks so far

Trylon Brand just came out with a new style(asbestos panels) that not only looks modern (unlike before)but is I think better than a c-pac roof. the metal required is less & it does not leak if correctly installed. I scrapped the c-pac plan & put in Trylon & love it. That & you don't have the problems associated with metal. Check it out you may like it & it was only I think 65 baht a panel......the rest of the molded parts were more than the old style but less than the route you are considering. It is a 10-15 year roof that will probably make it an easy 20 years.This is what it looks like. :jap:

This raises an interesting point - is asbestos still used in roof sheeting- I doubt it. Also any fibers from fibreglass could be a health hazard as well.

Yes they are still using the asbestos mixed in a cement fiber substance. And unlike the asbestos panels in the U.S. The only hazard from asbestos is when they cut the panels.

That's why I let them put them up. Roofs are not much fun any way for me . I prefer being on the ground working.Asbestos is like MSG & they will probably never stop using it. At least it is safe unlike the old school fiber! Or at least they claim.

The Thai manufacturers I have looked at are using wood pulp and NOT asbestos in their fibre sheeting, I therefore stick by my original statement - I doubt that asbestos is being used - please let me know who is still using asbestos so I can steer clear of their products.

May be the case but I see n wood in the makeup of the panels. And I still can buy lacquer base paints for automotive outlawed in most environmentally countries as well. Malathion paraquat & mercury are still in abundance. I would be more surprised if they didn't. I think there have been many threads leading that asbestos is still king here. If it is Australian tile it has none. Wood is also a premium here even the byproducts.If you look far enough I will bet the fools are still using asbestos in the commercial rigs for brake lining. Too bad Thailand is not to environmentally adjusted.

Back on topic the Tylon roof panels work great & look nice.

I''ve just done my roof with a cheaper brand . Is it just as good , well i wouldn't know . But i have visited the Bluescope shop and various other ones and there is no visual difference . There is a pricediffence between all the shop's depending on various factor's . Mine is deepred ( bit brownish/red like some school or official buildings in Thailand ) and 0.35mm thick . Price per m was 125 to 130 ( 125 for the big order , some small afterorder price went up to 130b) . The 0.25 or 0.27mm ( forgot what it was ) was 105 b , but the 0.35mm was a lot sturdier . Would it still look good in 10 years , i think so . I personally think 10 years minimum before any kind of aging showing .

Noise is part of the roof and if it bother's you , you can always add isolation . The heat properties of steel sheets are by far the best of any kind of material used in the tropics ( as is , fast cooling down ) . For the moment i have no issues at all with heat factor during the day , also probably because the roof is steep .
