You have entered into a contract with K&B Roofers to re-roof your home for $8000. They complete the work, but they did not do a very good job and you want them to re-do one section of the roof where the shingles appear to be too far apart, allowing water to seep through the roof and into your home. They refuse, so you refuse to pay. K&B now brings suit against you. However, it turns out that although they are licensed in Georgia, they are not licensed in Florida. Who will win and why? Explain your answer.

Could you still sue them for the shoddy work they did? Explain your answer.
