Stop in for a cup of coffee

I would really like to have a new windshield put in since my original is very pitted and could be part of the leak on the floor. When I had it out in the rain last summer I got home and had half the spare tire well filled up with water. It leaks that bad... Since the gasket is only 2 years old and not that much outdoor sun time on it do you think its still good or should I get a new one?
