My neighbors just sent me this photo of the roof of my kitchen. Their house is up much higher than mine so I can’t really see this roof garden except a bit of it from my hammocks down below. I love the looks of it. A few ferns there, as well. Does anyone know if this could undermine my roof? If I need to remove them, I’d love to plant them below in the garden. The two tall ones are gorgeous!!! (Photo by David Bershad.)

Judy at that age they are OK but I have seen them take over a tile roof to the point where they will lift the tiles and even damage them. I have even seen trees growing out of roofs. (BAD~!)
Did I ever tell you that when I was in school I worked summers as a Roofer in New Orleans. There the roofs were often slate and the very old nails would rust out leaving the slate loose, making them very dangerous. Like a fool, they would tie a rope around my waste and around the chimney or other object so if or when a shingle slipped out from under my feet, I would not go all the way to the ground. Kids today don’t realize what some of us went through to get an education~! But I was really lucky to get the same job each summer from a family friend. He was married to the sister of Edwin Edwards. My mother had been engaged to Edwin’s father, before she met my father and that was the connection Edwin had a brother almost my age named Marion too~!. (small world)

That’s why Prickly Pear are a noxious weed in Australia. They can grow to over 2 metres and spread easily.
It is best to get everything cleaned off. There must be a build up of dirt that will only cause more problems.
But then again I am 11,000kms away so what would I know about Mexico

Nope you are right. I’ve been told the same by a builder friend.

Anything growing on your roof that can be safely removed, you should remove it. We get things growing in our gutters every year and we have them cleaned out. At the least, they will change the way water flows off your roof — roofing is expensive. And it is impossible to know what will or won’t cause damage. It depends on the plant’s root system. I’d have it carefully removed.

I hope they can save them for me. A friend says they could damage the roof so they must come down. The big ones are so gorgeous I’d like to plant them.
