IKO does not offer long-life or 50 years of guarantee. Why is that?
The most common kind of guarantee on goods is a guarantee that the product is free from manufacturing defects in materials. This simply promises that the manufacturer properly constructed the product, out of proper materials. This implies that the product will perform as well as such products customarily do.
It is common for these to be limited guarantees, limiting the time the buyer has to make a claim. For example, a typical 90 day guarantee on a television gives the buyer 90 days from the date of purchase to claim that the television was improperly constructed. Should the television fail after 91 days of normal usage, which because televisions customarily last longer than 91 days means there was a defect in the materials of the television, the buyer nonetheless may not collect on the guarantee because it is too late to file a claim.
Time limited guarantees are often confused with performance guarantees. A 90 day performance guarantee would promise that the television would work for 90 days, which is fundamentally different from promising that it was delivered free of defects and limiting the time the buyer has to prove otherwise.
One situation in which the effect of a time limited guarantee is different from the effect of a performance guarantee is where the time limit exceeds to normal lifetime of the product. If a coat is designed to last two years, but has a 10 year limited guarantee against defects in materials, a buyer who wears the coat for 3 years and then finds it worn out would not be able to collect on the guarantee. But it is different from a 2 year guarantee because if the buyer starts wearing the coat 5 years after buying it, and finds it wears out a year later, the buyer would have a guarantee claim in Year 6. On the other hand, a 10 year performance guarantee would promise that the coat would last 10 years.
A lifetime guarantee is usually a guarantee against defects in materials and workmanship that has no time limit to make a claim, rather than a guarantee that the product will perform for the lifetime of the buyer. The actual time that product can be expected to perform is normally determined by the custom for products of its kind used the way the buyer uses it.
How long is a lifetime warranty?
If there is a leakage defect on your roof due to manufacturing defect, you will surely notice this within the first 2-5 years after installation. Any defects that suddenly occur after 35, 40 or even 50 years are not related to manufacturing defects, which is guaranteed in guarantee systems by shingle manufacturers.
Conclusion
That is why IKO does not want to confuse you by saying: “Our products are lifetime guaranteed”.
IKO offers you the maximum (Platinum) guarantee in the first 5-15 years, where material, transport and labour costs are covered in case of manufacturing defects and then after that period a pro rata material costs (Total guarantee).
IKO is in the roofing business for more than 60 years and is a financially healthy company without any external debts. This manufacturer’s Platinum and Total guarantee is more solid for you to depend on than a guarantee from a small local distributor.
IKO Platinum and total guarantee warrants shingles that are manufactured in Europe.
Roofing granules are one of the basic components of bitumen roof shingles. They give them an aesthetical appeal. A combination of colors often results in a creative look. The aesthetic function and appearance of granules is important but there is an even more prime role of shingle granules.
Roofing granules work as a shield, protecting the integrity of the shingle from the outside elements. More specifically granules protect and preserve the bitumen shingle from solar ultraviolet radiation. They are designed to protect the asphalt coating of shingles from harsh UV sunlight. Some lighter colors and special reflective granules can also make your roof cooler which results in lower energy and utility bills.
Granules, which are predominantly manufactured using natural stone, are crushed, screened and sized to various gradation sizes. This goes from very small particles (0,425 mm) to the larger particles (1,7 mm) with multiple groups of sizes in between, all selected in specific percentages of the overall granule blend mixture. These granules are manufactured in such a way that when applied to and embedded in the shingles asphalt coating, the particles interlock together in order to provide the absolute maximum coverage of the asphalt. There is also the advantage that more rounded granules hold better in the asphalt coating compared to the flat shape e.g. granules produced from the slate
