Solid Hardwood, Engineered and Laminate Flooring - Leveling and laminates

Old house. All floors, with exception of bathroom are plywood covered with(approx) 5/8" particle board. Will this accomadate laminate flooring? Also there is one area in the bedroom with a 3' x 7' area raised about 1". Can I cut out the 5/8" board overlying this area and put in a leveling compound directly onto the exposed plywood? Tim Carter has suggested using asphalt shingles to level. Feaasible? And can the laminate boards be placed directly over the shingles? I cannot correct the "hump" from underneath.

You have to grind or remove a hump, You cannot just fill around it, or you'll create the same hump, just a bigger area will be humped, unless you cover the whole floor to bring it up to that one hump.

Knock the hump down!!

No, If I cut out a 3'x7' section of the particle board I have removed the hump. Just need to "rebuild" this area to match the surrounding height. I will either go with leveling compound or use shingles. Thanks for the input.

oh, yes I mis understood.

Fill it with either or. If you use portand cement, make sure it is fortified with latex, or add latex if it doesn't. Not to be funny but just about anything will work, as long as it is a fairly hard surface, and you end with a flat surface.
