I have only roads data from US, Canada and Mexico in my DB imported using osm2pgsql. As it is mentioned in the osmupdate wiki page here

You need to update the OSM file of a small geographical region every other week. Do not use osmupdate. Redownload the file from one of the OSM file services, e.g. geofabrik.de.

Since I want to keep my db size as small as possible. will it be a good idea to do the following on a weekly basis

1 - Download the osm.pbf file

2 - convert to o5m (this step is for osm filter)

3 - filter for only road data

4 - import using osm2pgsql in slim mode using --drop

Any feedback will be highly appreciated

I'm not sure why you don't simply change your default.style file to only import road data, the main issue that even with that your database will grow due to edits outside of the area you imported (there are however a couple of ways to work around that).

Can you guide me regarding the work around?

One possible workaround is to use https://github.com/zverik/regional from Zverik . That's really simple to use (just call it with the parameters you need to trim the update file down). There's an example of its use described at https://wiki.openstreetmap.org/wiki/User:SomeoneElse/Ubuntu_1604_tileserver_load#Updating_your_database_as_people_edit_OpenStreetMap .
