Water getting into walls of house even after roof replacement
Just Guessing

I live in a small bungalow built in 1950. Shortly after moving in, I removed wallpaper to paint the interior walls. I noticed all along the front of the house that plaster work had been redone - probably to fix water damage done to the plaster. The walls seemed okay so I did a little sanding to smooth out the repair areas and painted. Over time I noticed these areas changing, getting "bubbly", and determined water was somehow getting into the house.

My first thought was the roof so I called a roofer who told me I needed a new roof (surprise surprise). But that winter I continued to have problems with the front interior walls. He said he put in rubber underneath the new asphalt roof and redid the flashing along the edge of the roof. He suggested gutters. At the time I had no clog gutters. They certainly never clogged, but I had incredible icicles hanging from them in winter - so I thought he may be right and I got all of my gutters replaced with conventional gutters and screen to keep them from clogging. Over time I continued to notice the walls deteriorating - both in winter and during heavy rains in the summer.

I was thinking about replacing the vinyl siding. I've noticed in the winter that the siding gets very hard - as though water has frozen behind it.

I've been told it's because my roof doesn't overhang the exterior walls. The roof ends right at the edge of the house. There are a million of these bungalows around, I can't believe this is such a difficult problem to diagnose.

If any one has any ideas I'm all ears. Thanks!

Not being there to see exactly how everything went together I can't offer specific advice, but now you understand why most houses have overhangs however slight they may be. It seems you're roofer did things right although I would have preferred to see them add a 2X fascia with a drip groove underneath before roofing to create more overhang. Too late for that now though. You probably need flashing up there to keep the water outside where it belongs but how to do that will vary based on how it's built. A good general contractor can do this, but whoever handles this you need to be sure that they guarantee in writing that their work will keep the water out If they are not that certain that they can solve this then you need someone else on the job.

If you can post some pics on a photo-sharing site then give us the link to them we can offer more specific advice.

A new, well done roof is excellent, but in your case - and this is something I'm saying without inspecting the house - I suspect that some water gets in where the walls meet the roof. You see, you first make sure the building is properly WRAPPED, then install a roof that properly covers the top of the walls.

What's under the siding is anyone's guess. Worse case: you will have to re-side. This time have the installer make sure the top of the wrap goes under the roof paper.

A general advice: don't delay. Random water leaks can cause catastrophic damages over time and can bankrupt you.
