Tree/Shrub Identification ?

Hi there,
I'm new to this site and was hoping some advice.
I have a tree in my garden that looks great when in bloom but I've noticed that its roots are spreading under my patio and constantly sprouting shoots.
These roots are even spreading into my neighbours lawn and sprouting up.
You can see on one of the pictures the small shoots sprouting up from the ground.
I've found these under heavy Indian Sand stone slabs.
The roots seem to very close to the surface and then start to sprout up.
You can also see in the first picture some dried out flowers/seeds
I'm a bit concerned that this tree might be a "Tree Of Heaven" , which apparently is very hard to control ?
This particular tree is about 10ft tall with thin separate trunks, it does flower into very small white seedlings that dry out and fall off fairly quickly after flowering, the leaves are serrated on its edge.
The new branches are very soft and pliable and if snapped there's a white residue inside.
In Autumn when there's no leaves the branches are very very dry and easily snap, as if the tree has totally died, but come summer it jumps back into life.
I've uploaded some photos.
And would be very grateful if you could identify this tree/shrub .  
I've uploaded some photos to help.

    It is a Rhus as you suspect.

    The only thing to do is either find a way to block the roots with some kind of barrier.
    And try and dig yp all the other bits of roots and shoots.
    OR. Sorry but I would use a root killer or strong weed killer on the shoots if they are hard to dig up or spread everywhere.
    Every bit shoots and regrows.

    Unfortunately I feel not something to grow near a patio or in a smaller garden. Or against a neighbouring fence.
    They are lovely looking things but one of the things I reckon ought to have a big warning label on if it is to be sold at all. :D

    Definitely looks like a Rhus to me, maybe Rhus glabra (we call it Staghorn Sumac in the States) if the barn-red seed cones sit erect on the branches.  If the seed cones drape down, it's likely what we call Flame Leaf Sumac.   We have 1-2 of the Staghorn variety on our 40-acre rural property but thankfully, not in the main pasture where 11 Brangus cows are grazing.  Luckily, we have none here at our city residence.  I'm told they are quite invasive, so I'm glad for that.  I'm not the real gardener in the family, but if my Dad were still living, he'd say to cut it down 4-5" from the ground and do either of two things.  Option one:  drill several holes in the stumps with the biggest drill bit you have and put lye granules + bit of water in them and let it slowly kill the roots off. That worked for a very large catalpa tree I removed.  Option 2: after cutting to a stump, brush the fresh cuts with a systemic killer recommended to kill woody plants (from your garden center) once a week until you feel certain no more shoots are trying to come back.  Of course, take great care to do on a non-windy day and be extra careful to not get it on any desired plants nearby.
