I recently had a roof put on an investment property but the contractor put 20-year instead of 30-year shingles (contract calls for 30-year). He admitted that a mistake was made and has offered to credit $340 toward my final payment for differnece in the cost of the materials.
My issue is not the cost of materials but the fact that I’ve lost 10 years on the life of my roof for a measly $340! I plan to keep the property for my retirement (currently 34 yrs old) so in all likelihood I will need to replace the roof in 20 years rather than 30!
My question is how do I put a value on these 10 years. In otherwords what would be the correct amount to credit me to level the value that I’ve lost? I only want what’s fair and am not trying to gouge the contractor. I understand mistakes happen.
Also, I would rather just figure out a value than have the contractor go back on the roof to replace the shingles which will cost him money and give me a headache.
What are my options here? How much should I be credited to make things fair?
