Generally, roof repairs are not tax deductible and do not qualify as a tax write-off. However, home improvements qualify for a different type of “write-off.” You can't write off a roof replacement on your federal income taxes.

Tarps are made of polymeric materials that are resistant to water, ice, and air. Tarps typically last up to 90 days on the roof, while those constructed of more robust materials can last up to two years. Roofing contractors recommend not keeping it for more than three months, which can lead to further issues.

TPO (thermoplastic polyolefin) roof sheets are a heat-weldable blend of polypropylene and ethylene propylene rubber components. They are polyester reinforced and flexible in colder temperatures. A properly maintained TPO roof may last 20-30 years.

The cost for roof replacement can be less when you have an overlay. With an overlay, new shingles are installed on top of existing ones. So you'll save on labor costs and disposal. That might be a good idea if the layers underneath are in good condition, including metalwork, flashing, and decking (sheathing).
