Be Extremely Careful With Building Material Manufacturer Warranties
I have been trying to send this message out for years
now. Just because a product states that it has a limited lifetime
warranty or a lifetime warranty, this doesn't mean that this particular
product will be guaranteed if the company that manufacturers the
products goes out of business.
It wasn't that long ago that building materials manufacturers would start one business and if it didn't work out like they expected it to, they would close that business down and start another one. This was pretty common in the construction business for quite some time and I don't know if things are any different today.
If you buy a building product that has some type of lifetime guarantee on it and you do not wish to ruin the guarantee, you should make sure that you read all of the installation instructions and follow them closely. Do not install their products any other way than those listed by the manufacturer.
This seems to be a big problem with windows, roofing, flooring and some exterior coatings. They promise you a limited lifetime or a lifetime warranty and if you don't read the contract or instructions close enough, you could find yourself with a building material product that might be guaranteed for life, but the labor to remove and install the damage products isn't.
It's not hard for a manufacturer of building materials to void their guarantees, especially if the building materials themselves have not been installed to meet their manufacturer specifications. You need to be extremely careful with building material manufacturer warranties.
