On the south border of our property we have a row of pine trees.  Our house sits about 40 feet away with the garage nearest to the pine.  There is a concrete patio that goes around the side of the garage to the back.  I'd like to grow vines on the garage to cool it more in the summer.  I am thinking of doing hops or maypop.  I'd like to grow several, but there is only a small patch to plant them on the front corner of the garage.  Will they be able to cover a large area without full sun?  Any other fast growing vines I should look at?

Not clear to me is whether you want the vines on the wall or roof (or both). Also, if there is little sunlight hitting that area,  would you see much cooling if you shaded it with foliage?

Most structures were not designed to have vines growing directly on them. The foliage will raise moisture levels and encourage the growth of slime on paint, wood rot, etc. Even on brick or stone, those lovely ivy vines can do a number on mortar over time. Much better to build a trellis a few feet out to let the air circulate between the plants and structure. Or plant a hedge that will allow a space.

Roofs with standard shingles might also experience problems if the vines trap moisture and decay.

i use grapes for shade here as they produce really large leaves..i have also used other vines, but they don't really provide as much shade as the grapes do..the leaves hold on well into the fall until really hard freezes.

smaller leaves maybe the woodbine vine, it is beautiful in the fall

hmm interesting...i was thinking mostly the wall climbing up some to the roof.  the garage is not shaded out during the middle part of the day and it gets very hot.

If you want a vine which will die back every year, so that you get the sun on the garage in the winter, you may look into Malabar Spinach. It is a vigorous grower, reseeds itself, and is edible to boot!

it doesnt necessarily have to totally die back in the winter as i can always prune it.  we have grapes and virginia creeper all along our fence so id like something different.  malabar spinach is different!  i am also considering getting pots to place along the garage for more vine action.

I agree with Jonathan. Keep plants and buildings separated.
Plants like moisture and have roots which try to go into small cervices. Moisture is bad for buildings and roots too. It is especially bad when the house is a timber structure. Then you might get termites.
In former times they often espaliered fruit trees at facades, that gives an earlier harvest and you might grow something that you could not grow otherwise. That doe not mean that this is good for the structure.
I would build a pergola and grow the hops or whatever there, maybe I would prefer vine anyway.
