You shouldn’t put a new roof underlayment over an old one for a few reasons. Old felt must be removed in order to assess the condition of your roof decking, such as rotting wood or other structural issues. Also, if your roofer doesn't install a fresh layer of felt as is required by shingle manufacturers, your warranty may be voided. Finally, old underlayment removal is often included in the cost of roof repair or replacement, so there's no real benefit to leaving it on before installing a new layer.

Start by asking friends, family, and neighbors if they know any reliable roof inspectors. You can also ask contractors that you’ve worked with in the past—they often have a network of people they can reach out to. Once you do find a roof inspector you like, check their online presence, read customer reviews, and give them a call. 

Make sure they’re properly licensed and insured in your area. It’s also a good idea to hire inspectors licensed by both the National Roof Certification & Inspection Association (NRCIA) and the International Association of Certified Home Inspectors (InterNACHI).

In most cases, yes, you will need to be home while your roof inspector checks your roof. The inspector will be able to complete the exterior assessment without input from you, but they will also need access to your attic space to look for signs of leaking, like pest infestation, water stains, mold growth, and visible holes leading to the exterior. They will also check the roof trusses, rafters, and supports to confirm their structural integrity. Roof inspections usually take between two and three hours, so plan accordingly.

Unfortunately, there’s no definitive answer to this question, but the wind rating of your shingles will give you a good idea of what wind speeds can damage your roof. If you’re concerned about damage, inspect your roof following windy conditions to look for signs of wind damage to your shingles. When in doubt, consider hiring a professional who fixes roofs to carry out an expert inspection. Remember that hurricanes, tropical storms, and tornadoes are likely to cause the most damage, but even severe thunderstorms can bring winds that compromise your roofing system.
