Re: Onduline corrugated cellulose-bitumen roofing

We have just finished building a 110 sqm house with onduline roofing. If rain noise reduction is an issue for you, then onduline is it. It also helps insulate the house against our tropical heat although we still added Aerofoam insulation just to make sure. It is not as sturdy as galvanized roofing material and can crack when mishandled so care in installation is needed. Watch out for installers who walk without care on the roof. We've been living in the house for barely a month and so far happy with our choice.

Re: Onduline corrugated cellulose-bitumen roofing

Thanks for that feedback.

It looks like a good product and being quieter than metal is nice. I am concerned though about long term. I noticed from Onduline brochure, that it is sold all over the world except USA. From searching the web, I think they used to sell in USA before, but then there was some kind of class action lawsuit having to do with the long term performance/behavior of the product and the supposedly lifetime warranty.

Interestingly, in USA, Onduline (French company) no longer seems to have a presence, but there is a new US company named Ondura that seems to be making a similar thing.

So I wonder what the story is with that lawsuit, whether there was any merit, and with this Ondura business.

Re: Onduline corrugated cellulose-bitumen roofing

Onduline / Ondura is a terrible product.

We used it on our new house build in 1995. A couple of years later the colour was faded and the impregnated bitumen/tar/asphalt was leeching through the sheets making the roof black/grey/faded green colour.
We complained to Onduline who inspected the sheeting - told us that it was a "bad batch" and painted it at their cost.
A couple of years later - the paint started peeling off in big strips and flakes.
Now the roof is an absolute eyesore. The sheeting sags, collapses, becomes thin and brittle with cracks and holes. The corrugations disappear and flatten out. Because of this the roof leaks. The paint cannot adhere to the tar that leeches through all the time and therefore peels off.
Onduline are not interested in my complaints now - telling me to repaint or replace..... Yeah right - at HUGE expense.
BEWARE - THIS IS A DISASTER PRODUCT - STAY AWAY FROM IT.
Searching the web I came across the websites with many people with the same horror stories as mine (e-mail me and I can give you the links if you wish and I can show photos).
There was a class action suit against the company as well - if you search the web you will find it.

Re: Onduline corrugated cellulose-bitumen roofing

Onduline....a major fire hazard...doesn't last...deform easily.

Been cheated thousands of dollars!!

Don't use Onduline!

What is the durability of an Onduline roof?
Durability depends on external conditions like weather and climate. Onduline roofs are
guaranteed waterproof for a 10-year period. However, some Onduline roofs have been
installed for more than 50 years in Europe, and 30 years in tropical countries.

Onduline_PH, although you have not properly introduced yourself I'm going to assume you are the official representative of the company here in the Philippines.

I see you're peddling your product on the other discussion threads. For that action alone I can delete your posts and ban you from this site. But I'm not going to do that now because of this thread that specifically discusses your product.

Instead I'm just going to delete your other posts and let you contribute to this discussion thread.

If there is anything we can help you about Onduline roofing materials just let us know. We are more than happy to help.

Thank You!!!

[h=2]ONDULINE a great alternative roofing applications[/h] Do you know that ONDULINE roofing is already in the Philippines 7 years ago? If that is so, how come this excellent roofing material is not popular? You might know the answer why. For what I know they lack the appropriate people who can provide the right INFORMATION.

@ Onduline_PH,

You need to know more about these roofings as they will help you a lot on metal roof estimate. You need to also get some more details form the buyers who are out there helping them.
