Install hardwood floor on convex surface

I am installing hard Maple pre-finished harwood floor in my second floor bedroom. The floor seems to slope up a little bit from one end to the other along the length of the room. About 17" from the wall it then slopes down between 1/4" to 1/2'. I started laying down the planks from the good side and after a few row had problem going over the ridge. If the board is long than the edges are not flush. The outer board is slightly higer. Initially I started ensuring that the boards end approx 17"before the wall and use a different piece for the last end. There are 2 problems with this technique. I got a fairly straight joint line about 17" from the wall (offset by an inch or two) and the second is the floor seems to slope over the other side. As I add more rows the slope seems to gradually increase. the boards seem to be sitting fairly tightly on the sub floor with no gaps.

Is this going to create problems for me later? Will the floor open up at the ridge later in the years? I have tried not to bend the planks to fit, thereby avoiding any tension on the wood. I am hoping that this will prevent the wood from snapping out. is there a better way?

I don't want to rip the already laid down floor to fix this. I am also thinking of removing some of the end planks and than place some shimmy's on the end to level the floor. Maybe cut strips of 1/4"ply and place near the wall. Will this work? It may leave a gap between the floor and the sub. Will this cause the floor to squeak later? I need a quick solution as I want to finish the flooring by the next weekend.

Anyone with similar experience, please advise.

Thank You.

Engineered floors will telegraph the subfloor pretty well, so you should level the subfloor before installation. Getting some bags of self-leveling compound and laying that down would be your easiest solution. Most compounds can only do about 1/4" in thickness at a time, so be sure to read the instructions first. Are you gluing or nailing the floor down? If you are nailing, then yes the floor will squeak later as it settles in its place and fully acclimates to your environment if you continue with your present plans. If you are using floor adhesive the only place it might squeak is if you don't have the right trowel size and skim over a low point in the floor. Is your floor running horizontal or vertical to the ridge? If horizontal, then yes, the floor will probably open up after time as the house continues to settle. If vertical, then the tongue and groove of the floor should hold it together. You need to find out why you have a "ridge" in your floor. Is this a spot where you have a loadbearing wall downstairs and the second story overhangs this by 17"? The weight of the top story could cause such a ridge, if it overhangs the first floor support beams. Just a few thoughts.... Brian
