Metal roofs are one of the most durable, reliable types of roofing NYC material out there. They can last decades without needing to be replaced, which is a huge benefit to homeowners. But while they’re great at protecting your house from rain and snow, they can still suffer damage over time—and if you don’t notice it until it’s too late, you could be left with water leaks that cause serious damage. Here are some signs that it might be time to replace your metal roof:
The roof is rusty
One of the most common signs that your metal roof needs to be replaced is rust. Rust is caused by water seeping into the seams of your roof and corroding the metal underneath. As this happens, the color of the entire roof will turn from black to brownish red and eventually become completely rusty.
Rusting isn’t limited to areas where two pieces of sheeting meet; it can occur along seam lines as well. If you notice any rust spots on your roof after heavy rain or snowfall but don’t see any evidence of leaky seams during dry weather, it’s possible that there’s an issue with how much moisture gets trapped underneath those sheets’ surfaces when they’re joined together at certain points along their length. This can lead not only to rust but also potentially fatal structural damage if left unchecked over time!
Leaks appear
When leaks appear on your metal roof, it’s cause for concern. Leaks can be a sign that you need to replace your roof or repair it immediately.
If you notice any of these signs, contact professional roofing contractors in New York City as soon as possible.
- Water stains or puddles form around the house or garage.
- There is standing water inside the attic or on top of the decking surface.
- The sheathing underneath is rotting and damaged because of moisture build-up in the attic space due to blocked vents and/or poor ventilation systems causing heat to be trapped under the roofing material.
Shingles are curling or missing
Shingles can curl at the edges. Shingles can become loose and fall off, exposing the tar paper underneath. The shingles may also get discolored over time, which means they’re losing their ability to reflect sunlight. Heat buildup causes this discoloration, which makes your roof more susceptible to heat damage and failure. If you notice this issue on your metal roof, it’s time for a replacement.
Granules are missing from shingles
If you see granules missing from your metal roof, it’s time to get a new one. Granules are the protective layer on the surface of metal shingles and help prevent moisture from getting into the shingles and causing corrosion. If you see any granules missing from your metal roof, it’s much more vulnerable to damage because there is nothing protecting it from moisture or external elements.
Holes are visible in the roofing material
Holes are one of the most common signs that a metal roof needs replacement. The holes can be caused by birds, squirrels, or other animals; hail, wind, or falling branches; rusting, corrosion, or oxidation; fire, and other forms of damage.
If you have more than one hole in your roofing material, it’s likely time to replace the entire roof if you want to achieve long-term durability and protection against further damage.
Blistering paint
A common sign that your metal roof is failing is blistering paint. This can occur when the metal under the paint heats up, expands, and pushes against the surface of the paint. As a result, you will see bubbles or blisters on top of your metal roof’s surface. Blistering can also be caused by moisture getting trapped in between layers of paint resulting in rust or corrosion underneath (you may see brown spots).
Conclusion
If you’re not sure if your metal roof needs to be replaced, get in touch with a local commercial roofing company who can assess the situation. A professional will know how to inspect and test for issues that might indicate a need for replacement.
