Hello everyone,
We initially planned to use concrete roof tiles from Nelskamp, but since we unexpectedly have to reduce the roof pitch from 23° to 12°, our prefab house supplier now wants/needs to change the brand. There are clay roof tiles from ERLUS that are supposed to be watertight even at such a low roof pitch (which we really hope is true).
I had already ordered samples from Nelskamp because of the color and shape, and I have now also ordered samples from ERLUS. I noticed that the ERLUS tiles seem to have color sprayed on only one side, meaning one side of the tile still looks red, like traditional clay tiles, while the other side is anthracite and black. The Nelskamp tiles appear to be colored through and through.
To me, this visually gives a somewhat lower-quality impression, since when putting the tiles together, you can see in some places the red tile showing through (scratches, small chips, etc.). The sample tiles all arrived individually and very securely packaged, but on the construction site, handling will probably be less careful. You might expect that many red spots will show through the black color...
Another point is the surface texture. The coating on the ERLUS tiles seems extremely rough! If you did a cotton swab test, you might think a lot of fibers would stick to these tiles. The Nelskamp tiles feel much smoother to me (though not completely smooth). This leads me to believe that dirt, moss, or other contaminants would settle much more easily there, and the roof might start looking untidy after a short time.
These are all personal impressions and assumptions from me as a layperson—I really have no expertise in this area. That’s why I wanted to ask if any of you can share your thoughts? Have you had experience with ERLUS? Or can you comment on the “roughness” of their tiles?
As always, I appreciate your feedback.
Best regards

Thank you. So you have almost the same brick, and in anthracite as well...
I just checked the specifications for both bricks (yours and mine). Both your anthracite and my anthracite and matte black are engobed, while diamond black and titan silver are fully glazed, which probably explains the noticeably smoother surface.
Maybe we just perceive the texture differently; it’s hard to compare from a distance...
When did you build?
I think I just have to let it go. Things will probably go wrong anyway, and hopefully the bricks won’t look terrible after only a few years...

I just checked the specifications for both bricks (yours and mine). Both your anthracite and my anthracite and matte black are glazed, while diamond black and titanium silver are high-quality glazed, which probably explains their noticeably smoother surface.
Maybe we just have a different perception of the roughness; it’s hard to really compare from a distance...

The construction time was almost a year. The roof was, I believe, finished in November 2020. We had various Erlus as well as Nelskamp bricks. I’m not exactly sure, but I don’t recall a major difference.
