Help! We'd like to install a stamped concrete patio on the back of our house. We have a mature Japanese Maple tree that has roots heaving up the very old, existing brick patio. Our intention is to have the tree removed as it hangs over onto the roof and is VERY close to the house. Also of concern is there is a gutter downspout right at that corner of our house where the patio edge will be. Although it sends water away for the house and the patio, we are wondering if, between the hole left by the tree and root removal, the dampness of the area in general, we'll be creating "perfect storm" conditions for a concrete patio disaster. Any advice? Our second choice is a wood deck so this isn't a deal breaker!
