Metal roofing is an ideal choice for property owners who are concerned about improving energy efficiency, and who want to add a distinguished design element to their homes and structures. Although metal roofing sheets are significantly better than shingles for roofing, these still wear with age and need repairing, patching, and re-roofing, eventually. Metal roofing can last decades, if it is maintained properly, otherwise these can prematurely corrode, rust, and then holes begin to form.
When holes appear in metal roofing, usually due to rust and corrosion, patching can be an effective way to stop leaks, temporarily. However, it might be more affordable to re-roof a section instead of just patching holes, and then having new ones form from older metal sheet roofing later. This is a decision a metal roofing expert can help you – when to repair, patch, or re-roof?
To Patch or to Re-roof?
Have recent winds and rain exposed a few leaks in your roof? Well, it does come as a surprise to most homeowners to discover a rusty roof because the roof is usually out of sight and out of mind, until it begins to leak. It’s true, years pass quickly when you are living in a home you love. Although, patching holes can stop water from leaking, a rusty roof can’t get any better on its own, so replacing old sheets with new ones is the obvious, permanent fix.
The main reason metal roofs begin to corrode and rust is that their protective coating has eroded, thus exposing the base metal to the elements – the sun, wind and rain. There are various grades of metal sheets for roofs available, and when it does come time for re-roofing a home, it is highly advised to always choose the best grade metal sheets possible because they will resist rust and corrosion longer.
However, although replacing metal sheets is the best solution for rusty metal roofing sheets with holes, there are times when patching these is best, and the most qualified person to make that distinction is someone who knows about metal roofing, such as expert roofers at Johnson Roofing.
