I am the proud owner of a nearly 100-year-old house with a mansard roof. The roof covering consists of old but well-preserved interlocking clay tiles (Biberschwanzziegel). These now need to be removed as part of extensive roof insulation work. An experienced roofer advised me to reuse the old interlocking tiles, even though they are several decades old. He said that modern tiles would not come close to the lifespan of the old "quality" material.
Can any of the experts here confirm this? 😕 My current roofer advises against it, citing the higher costs for the "careful removal" of the old tiles. Simply throwing them off and installing new tiles would be significantly cheaper, and there would be hardly any difference in quality.
