It’s possible to install your chimney cap in some areas, but it’s usually better to hire a professional. Before you attempt a DIY chimney cap installation, check to see if your local building department requires a permit. If it does, you should hire a professional to pull the permit and complete the work for you. Even if you don’t need a permit, getting up on your roof is dangerous, especially if you have an aggressive pitch or slippery roof material, like metal. Hiring a chimney professional guarantees the job is done correctly and keeps you safe from injury.

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.

Flat roofs are a solid option for people who want extra outdoor space. Flat roofs are very common in other parts of the world and only recently has the U.S. started to see the benefit in the increased space. Flat roofs are also easier to maintain and pose much less of a safety risk, which allows for more DIY work for handy homeowners. Some people also build green or living roofs that grow plant life. 

While you can technically install TPO roofing over an existing roof, it isn't always wise to do so. The more layers of material you add to your roof, the more weight it must support. You may also develop moisture issues by covering your existing roof with TPO. Your local building codes and regulations may actually require you to remove the existing roof before adding TPO, so check with your local municipality.
