What should I do about possible snake in house?

I apologize for the long story. But a couple of months ago we had a storm that did a lot of damage to our house. It created an opening where the fascia board was torn off and roof was practically destroyed. It took roofers 1.5 months to get to it because of ongoing bad weather. At some point I heard beards in the attic area, right over the torn off fascia board. The roof was repaired last week and the fascia put back. A few days later we found a six foot brown type snake on the roof, wrapped around the electrical balast. My husband took it to the woods about 100 yards behind the house. I seriously have a phobia about snakes and hyperventilate, etc. I have actually seen psychologists because it interfers with my life. A couple of hours later we were looking at the house and my husband was trying to convince me there was no opening for it to have come OUT of the house and that it was in fact an outside snake when the snake was back on the ground in that area. He took it miles away and set it loose again. Today a friend pointed out to me that the snake was probably coming back for eggs it might have laid. I'm terrified these baby snakes are in my house. Any snake lovers know? What would cause it to come back to the exact same spot? What is the liklihood of it coming back for its eggs and could it have laid eggs in my house? Any input is greatly appreciated.
