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.

The material and frequency of maintenance are the biggest factors for determining the longevity of your shingles, not the color. For instance, luxury asphalt shingles can last 30 years or even longer, while slate tiles have an impressive lifespan ranging from 75 to 100 years. That said, lighter-colored shingles can help reduce your energy costs in the summertime.

Sometimes. Professionals may be able to remove the old roof and re-attach it when completed, depending on your blueprints. That can help you save money. But this method is not without its risks. Larger roofs may crack during the transportation process. And if the roof is old or has problems, it may be better to replace it entirely. Keeping the old roof isn’t always possible if you are making significant alterations to the roofline.

Thatched roofs are expensive for two main reasons: high labor costs and low supply of available roofers. The labor is more intensive for a thatched roof than other roof materials, so your contractor will work longer and charge more for the installation. There are also few professionals with the specialized skills and experience to install thatched roofs. Since the supply of available professionals is low, the cost of compensation is high.
