hail damaged roof, advice

Hello to all,

Live in Houston, and when we had 18" of ran in 24 hrs, some of that included hail. Had someone check out our roof and he said we had hail damage.

Claims adjuster came out and agreed. Here are a few questions for the roofing contractors, and the ones that know insurance agencies. First, here are the facts: dark gray composition shingles, 2 story house, has gutters on all edges where appropriate, 2 chimneys, 3-4 turbines, summers can get to 100+ for a month straight, just had a lot of expensive landscaping done...

1. If we currently have 3-4 roof turbines, can the roofing company install ridge venting instead?

2. Is ridge venting or turbines better? or both?

3. We put in a pool last year and there's expensive travertine pavers all in the back yard. What can the roofers do to protect them from any damage?

4. Is not expecting any damage unrealistic ?

5. When doing the pool, we added a covered kitchen area that are composition shingles too. These shingles are 1.3 yrs old. Should they be replaced also?

6. Is there anything else I need to mention or discuss w the selected roofing company prior to them doing the job so we both have set the proper expectations?

thank you very much,
