Living in Central Florida, is metal roofing less expensive during the fall and winter months vs. just before and during hurricane season?
During & after hurricane, all roofing is MUCH MORE expensive, because of immense demand and short supply. My friend from Connecticut goes to Florida after hurricane and has work there for at least 3 months going forward.
Because there is so much work, roofers can charge higher than normal prices. On top of that, shortage of materials further increases the costs.
So it’s best to replace the roof during “off season” – during the winter.
