Eurotech Roofing

Few years ago Eurotech provided shingles and installation for my house. Fast and terrible installation was completed for one day – while the other contractors in the neighborhood spent 3+ days per house (houses are approx 4,000 sqfeet each).
After completing my house, they did complete similar installation in few other houses in the neighborhood. Since then, whenever we have wind 60+ km/h, only these few houses have fallen shingles. All other houses used other contractors and have not had any problem.
For the first repair, Eurotech did send people to fix the damages for free. For all other repairs, they have been asking for money and ignoring the fact that the damages were result of the Eurotech wrong original installation.
My few neighbors and I have 2 options:
1. Let Eurotech (or other contractors) fixing the roofs and charging us multiple times each year for the Eurotech terrible installation, or
2. Find a contractor who knows how to install shingles and replace these 3-4 years shingles (pay full price again).
