Encoding specificity refers to Endel Tulvingâs notion that in order to successfully retrieve something from memory there must be a match between how information is originally encoded and how it is available when being retrieved from memory.
Shingle Roofing. Shingle Roofs last between 10 â 30 years in Phoenix depending on the quality of the material on your roof. Regular 3 tab shingles last between 10 â 15 years in Phoenix. Architectural or dimensional shingles are a lot thicker and can last from 15 â 30 years.
A 20 yr shingle will last an average of 15 yrs sometimes less. A lot depends on the installation , shingle over reroofs dont last as long. Or if underlayment/felt paper was not used that takes years off the life of a shingle. In your case hopefully they used a 30 yr shingle which should last 25 yrs. I know most states I work in now use a 25 or 30 year shingle on new work .
