Mostert De Winter B.V.

In July 2019, we had a moss sedum roof installed on an extension of our house. It looked neat. a reasonably well filled roof with sedum moss. Because they were type of tiles, you could clearly see the edges of the tiles and not one whole. But if it had grown closed you would no longer see this. Shortly after construction, the roof became increasingly bare and then looked more black than vegetated. the tiles became smaller and the gaps between them only got bigger. Birds tore up the subfloor and large tufts stuck up through the mats. I contacted them and they came by one more time to take a look and bring some fertilizer granules. This could last me years. And in terms of vegetation, I would have to wait and see. It would come back on its own. I could cut away the loose strands and push them back a little under the mats. Now 3 years later I am still looking at a black roof with more moss than sedum. If the weather is nice for 2 days, everything dries up again and the fragile sedum plants have as good as disappeared. It is absolutely not a maintenance-free roof. I have to water it frequently to keep it alive at all. birds still tear things apart. Houses around us that also have sedum moss really don't do anything about it, and they have a beautiful roof filled with sedum. I'm very disappointed. We opted for quality and sustainability instead of a cheaper roof garden 3 years ago, but so far I have seen very little of the quality and sustainability. You have to pay for maintenance, but this went wrong shortly after installation, and that suddenly means no warranty or service. No, the advice is to wait and that is the service. Oh yes, and a bag of fertilizer to make up for it.

Wij hebben in juli 2019 een mos sedum dak aan laten leggen op een aanbouw van ons huis. Het zag er netjes uit. een redelijk goed gevuld dak met mos sedum. Doordat het soort tegels waren zag je wel duidelijk de randen van de tegels en niet 1 geheel. Maar als het dicht gegroeid was dan zou je dit niet meer zien. Kort na aanleg werd het dak steeds kaler om vervolgens er meer zwart uit te zien dan begroeid. de tegels werden kleiner en de kieren er tussen alleen maar groter. Vogels trokken de ondervloer kapot en grote plukken staken door de matten heen omhoog. Ik heb contact gezocht en ze zijn nog 1 keer langs geweest om te kijken en wat kunstmestkorrels te brengen. hier zou ik jaren mee kunnen doen. En qua begroeiing zou ik af moeten wachten. Het zou vanzelf weer terugkomen. de losse plukken zou ik weg kunnen knippen en weer een beetje terug kunnen duwen onder de matten. Nu 3 jaar verder kijk ik nog steeds tegen een zwart dak aan met meer mos dan sedum. Als het 2 dagen mooi weer is dan verdroogd alles weer en zijn de fragiele sedum plantjes weer zo goed als verdwenen. Onderhoudsvrij dak is het absoluut niet. Ik moet het frequent water geven om er uberhaupt nog wat leven in te houden. vogels trekken de boel nog steeds kapot. Huizen om ons heen die ook mos sedum hebben doen er werkelijk niets aan, en die hebben een prachtig gevuld dak met sedum. Het valt mij erg tegen. we hebben 3 jaar geleden gekozen voor kwaliteit en duurzaamheid in plaats van een goedkopere daktuin, maar ik heb tot nu toe heel weinig van de kwaliteit en duurzaamheid teruggezien. Voor onderhoud moet je betalen, maar dit is kort na aanleg al mis gegaan, en dat is ineens geen garantie of service. Nee het advies is wachten en dat is dan de service. Oh ja en een zakje kunstmest als goedmakertje.
