Welcome Keiki! Thornless and fairly shade resistant are kind of difficult for Zone 5. Most I can think of are rated the default zones of 6b and higher. I'd think you would do best with a once flowering type. Repeat flowering often depends upon removing the hips as they form to stimulate the repeat flowering. With it growing up into trees, that may be difficult, or at least, undesirable. If you join Help Me Find (link below) and do an advanced search, it permits you to narrow it down to climbing, color, shade tolerant and hardiness to your zone. Click on each suggested rose to determine if you like it and if it is available for you in this country. Good luck! I hope it helps.

Cut off a piece, strip all but tip leaves. Cut the branch to about 5" long, stick the end in root tone. Put it in very well draining soil (I mix extra perlite with potting soil and river sand or paver sand) and stick a plastic bag over it, with a small hole cut in it (a tent) tie the bag on. Bottom water (a very little bit) and leave it for a week or two somewhere in a shady, cool location. I root my stuff in a 79 degree environment, in light but not direct light.

But everywhere I look for info has basically the same thing as far as info? And planting 5' from the house would be a problem with a tree of that size, really? I feel like my rhododendron is double the size and it's RIGHT next to my house..not by choice, it was here when I moved..I just never got rid of it because it still seemed healthy and still flowers nicely..but yeah I wouldn't think it would be an issue there?
