an old guy a work told me that you can put a coating of linseed oil on your asphalt shingle roof to make it last 3-5 more years instead of getting a new one.
he claims it reconditions the shingle. what do you guys think? would you do it?
No.... Put the time and money into a full rip, ice and water membrane, and architectural shingles.
