I have an IP in Brisbane with a bad roof. It was flagged during the B&P and so we obtained a quote from a roofer to have it repaired. The property is quite old (1960) and the roof is original and so it may be nearing it's end of life. However roofer 1 is confident that a repair will keep it going for 10 years and the roofer has a 10 year guarantee on his job. My PM ended up getting a quote from a second roofer and this roofer doesn't think the suggestions from roofer 1 will do much and is instead advising to replace the roof within 5 years. Should I be getting a third, fourth quote and opinion on the roof? I do like the confidence and 10 year guarantee provided by roofer 1, but it seems like he runs the company by himself so I'm not sure how reliable he is.
