Roofs: They're Definitely at the Top!

You can say a lot of things about roofs, and most of them might be true. But one thing that nobody can argue with is that roofs are tops. This statement can be taken in several ways. A roof does for the top of your home. It can also act like a "top" or lid for your home, keeping the rain out. Then, there's the third meaning, which is the one we happen to like the most: roofs are the best. (People say things are "tops" when they really like them.) Since we like roofs so much, we've decided to write about them, and you've discovered the blog where we do that.

How Do You Know When To Replace A Metal Roof?

Brian Riley

Metal roofs are very long-lived, but they do not last forever. It's important that homeowners know how to recognize when a metal roof is near the end of its lifespan and needs replacement. But without being able to check for things like lifted shingles or popped nails, how do you know a metal roof is in disrepair? Here are the key signs it's time to look into metal roof replacement.

Discolored Spots

Most metal roofs these days are made from steel. The steel has been coated in a special layer of zinc to prevent it from rusting. This process is known as galvanization. Eventually, the galvanized layer will wear off, allowing the steel to be exposed directly to the elements. Then, the steel will begin to rust. This rust starts to appear as discolored spots on the roof. You may not need to have the roof replaced the moment rust spots appear, but you should definitely have a roofer come take a look.

Wrinkling and Waviness

The metal panels of your roof are installed in a way that allows them to expand and contract as the temperature changes. However, the fasteners and underlayment associated with the metal panels can break and wear out over time. This can impede the expansion and contraction of the panels, eventually causing them to look wrinkled and wavy. If your metal roof looks wrinkled and wavy, it is probably time to replace it — not just because the panels are worn, but because the fasteners and underlayment have likely failed and could lead to leaks.

Lifted Panels

Stand where you can see the edge of your roof clearly, and look at the areas where the panels come into contact with the roof surface. Are any of the panels lifted on the ends? If so, they are no longer offering your home adequate protection from rain and wind, and you may want to consider a roof replacement.


Finally, venture into your attic. See if you notice any signs of roof leaks, such as high humidity or drops of moisture on the attic beams. Leaks might just mean your metal roof needs some repairs, but if your metal roof is on the older side, a replacement could be necessary.

Metal roofs can last for many decades, but they do eventually start to fail. Keep your eyes out for the signs above, and contact a roofing company if you notice them.
