I usually top-up the tires on my road bike about once a week. They lose maybe 5-10psi in that time. You do get a tiny bit of leakage and it shows more quickly on a road bike due to the higher pressure and lower volume than an MTB tire.
Be careful not to overinflate - take what's written on the sidewall with a grain of salt. I found that out the hard way when I used to inflate to 120psi and after a blowout while going downhill I checked the manual for my wheels which said that they are rated to 115. I now use 90psi but could go lower, especially with the rough-chip roads we have. MTB pressures are of course a lot lower.
