Screened porch addition

[vholbert]

I'm building a screened porch attachment to my home. The gabled roof (stick built with structural ridge beam) will be hipped directly into an existing roof in a T arrangement (new roof ridge perpendicular to existing). The existing exterior wall where one end of the new structural ridge beam will attach has a series of windows (four, to be exact) directly below the location where the new ridge beam will fall. Because the structural ridge beam of the addition will fall over the windows on the existing exterior wall, the contractor will actually add another microlam beam above the roof of the existing roof and post it down on either end to the window wall jacks on either side of the windows. This allows the load of the structural ridge beam of the addition to be carried down the kings on either side of the window (which are already carrying the header load from the windows) rather than trying to carry this load on the existing header. I guess I would like reassurance that the exterior wall will carry the extra load, but I suppose a structural engineer would be needed to answer that. Also, the foundation in that area has been repaired in the past (prior to us owning the home) for cracks that apparently leaked water. We have had no issues since we have lived here, the cracks are sealed and dry, and there is no evidence of settling (no cracks in the drywall and no offset in the basement wall). There is a crack in the mortar joint of the bricks on the outside of the house, but is looks relatively minor. Something I should be concerned about?
