When planting for shade it is more important to shade the east and west walls of a house than the roof. Small trees planted fairly close to the house for wall shade will be less hazardous than large trees which can fall on the house. For more information, see these links: Urban Design for a Wind Resistant Urban Forest and Choosing Suitable Trees for Urban and Suburban Sites.
If you are a do-it-yourself landscaper, dig the hole wide and shallow so that the top 10% of the root ball is above ground level. The outer inch or so of the root ball should be shaved off to remove all circling roots, and mulch should be applied 3 inches thick and in an area 2 feet in diameter for each inch of tree trunk diameter. Mulch should come up to the edge of the root ball, but not cover it. Roots will expand best when there are no soil differences, so it is best to stick with the natural soil and not amend the planting hole. Establishment takes time and providing enough water is critical to tree survival. For more detail see this link: Planting Trees and Shrubs.
