Roofing FAQs, answered by experts

This will depend on your existing roof to some degree, but it’s common to raise a roof 4 to 8 feet. The exact amount you can raise is subject to the existing structure. For most homes with average roof slopes—20 to 45 degrees—you can raise the roof around 5 feet.

Depending on the condition of your roof, you may be able to add flashing to it. If you’re looking for a way to maintain its integrity while saving some money, you should ask a roofing pro if this is an option. Keep in mind that if your roof is in poor shape, a full replacement may be necessary before flashing is installed.

Tile roofing is durable, fire-resistant, and energy-efficient. It also adds aesthetic appeal and, with proper maintenance, can last 50-100 years.

A cool roof can be worth it in the right climate. Cool roofs are excellent at reflecting solar heat away from your home, so if you live in a warm or hot climate, they can be a great roofing choice. Some cool roofing materials are even eligible for tax credits. However, they cost more than traditional roofing and don’t retain heat as well as traditional roofing, so they’re not ideal if you live in a cold climate.

It’s the reverse of home de-winterization. To winterize, you purge your plumbing system (including your water heater and all piping) of water. Some experts also recommend filling fixtures with an antifreeze solution. Other tasks involve winterizing sprinklers, sealing foundation vents, check weatherproofing around doors and windows, and more.
