Denver Roofing: Article About When Do Metal Roofs Need Replaced?
One of the main reasons people choose to install a metal roof is due to its incredible longevity and low maintenance. While these kinds of roofs are designed to last 60 years or more, that doesn't mean that they're invincible. Eventually, a metal roof will have to be replaced, but it can be difficult to tell the difference between a roof that needs repairs and one that needs to be replaced. A homeowner should always consult with a Denver roofing company for a professional opinion.
The most obvious sign a metal roof needs replacing is when it leaks despite a number of repairs. Metal will eventually corrode or rust, creating small holes in the metal that allow moisture to seep in. Even if a metal roof is consistently treated with a polymeric sealant, the metal will still eventually reach the end of its lifespan. All the waterproofing does is help the roof shed any water. It won't protect the metal from the weather, debris or damage from tree branches or hail. A roofing professional will perform a thorough inspection of the roof to see if the leaks are related to deteriorated flashing, loose fixtures or blocked gutters before assuming the entire roof needs replacement.

Excessive rusting doesn't just cause leaks. It also makes the home look unkempt. While some rust problems can be eradicated using a few different professional methods, the rust is sometimes so extensive that it is not possible to get rid of it all. Some homeowners or professionals think rust can be painted over, but the paint will quickly flake or peel away when the rust eats through it.
Metal deterioration will occur no matter what. The roof can have been immaculately maintained for fifty years, but if the metal has reached the end of its lifespan, there is no way to stop it. If age hasn't caused the degradation, extreme weather conditions may have contributed. Rust that was never treated will also deteriorate the metal and cause irreversible damage. Deterioration will ultimately lead to leaks. These leaks may not be large to begin with, but eventually they'll get bigger or cause enough damage. Leaks can ruin the siding of the home or cause bubbles to appear on the ceiling.
The most important thing a homeowner can do is consult a roofing contractor that's familiar with the lifespan of metal roofs. Some problems can be repaired with minimal work, but there are some problems that aren't fixable and necessitate a total roof replacement.
