Contractor Next Door Caused Damages to My Home

[Chuchi]

My question involves a consumer law issue in the State of: CA
During the last 4 weeks a roofing contractor demolished and re-roofed a roof over a large condo building.
My house is less than 7ft away from the condo building, my house is an older small cottage.
There was a lot of vibration and ground shaking caused by the heavy trucks coming and going and sometimes being running idle. When the asphalt pump was operating all my windows rattled, dishes clattered and shelves moved. This felt like a magnitude 3 to 4 earthquake, for several hours each day, day in, day out.
I have an extensive doll collection on a big glass display case.The shaking was so bad, I decided to box the dolls and remove the glass shelves. Later I noticed the windows were out of alignment and could not close easily, leavinga small opening at the bottom.
Last Friday the valve on the water line to my water heater failed, spraying water under pressure all over my basement. I cut off gas and water as soon as I noticed the problem. Still i got a wet basement.
Last Saturday my water main (main water supply) failed, releasing a lot of water down the sidewalk for over one hour. The utility came and shut the water off.
I have been without hot water for 4 days and without water for 3 days.
A new water line will cost $2500, and dehumidifyin my basement $500. My contractor wants $20 per window to re-align them. Depending the method of installation, landscape damage may be about $400.
I attempted to contact the roofing company but I have not heard back.
My house, without water, is not habitable. I am a visually impaired individual on a fixed income.
What are my next steps? Members of the condo association are aware of my plight and the informal response is "shit happens". The roofing co is reputable and solvent.
Do I need a lawyer? small claims? contact the roofer insurance?
