Roofing materials are only as good as their weakest link. In the case of metal roofs, screws play a big role in its long-term efficiency. Unfortunately, exposed fastener roofs in both corrugated and standing seam variants have rubber washers, which are very unbecoming if you consider them as lifetime metal roofing screws. Certainly, Corpus Christi TX homeowners can't maximize the 50-70-year metal roofing material lifespan they hoped they can.
As reputable Corpus Christi TX metal roofers with decades of experience handling many roofing projects in the last few years, we advise homeowners to take note of leak areas around their metal roofs. While they're not using lifetime metal roofing screws, owners can at least inspect their condition and even DIY apply screw placement sealant. What are these, you might ask? Hunker has a great description about them.
Lifetime Metal Roofing Screws: Sealants
At least twice a year, you want to inspect your metal roof fasteners for potential movement in the screws, or sealant failures. This is especially important if you have exposed fasteners. Check all screws and fasteners to make sure they are tight. Movement can thrust screws out of their holes. If you see a screw, and possibly threads, sticking up above the level of the gasket or roof panel, you will need to refasten it. Check your attic at least twice a year, if not more often, for leaks.
Metal roof screw placement must include good sealants. Sealants may fail around the screws. They typically last about 20 years, but roof panel and fastener movement can damage it. Also, the gaskets that come with the fasteners can fail. Check for tightness, discoloration, corrosion or breakage. (Continued)
However, even if they might seem close to lifetime metal roofing screws as homeowners can get, sealant-applied screws still bring with it several challenge. Exposed roofing fasteners and screws will rust similar to their roofing material. In fact, aluminum roofing using exposed roofing fasteners made of tin or steel will see accelerated corrosion.
Most contractors will advise homeowners to invest in long-lasting high-quality exposed fasteners. These receive additional aluminum or zinc coating (similar to steel and tin metal roofs) and can last as long as the roof material possibly can. MBCI has a great post about exposed fastener rusting and what you can do about it.
Lifetime Metal Roofing Screws: Preventing Rust
Anytime you have an exposed fastener on a metal roof, you risk rust—the term commonly used for the corrosion and oxidation of iron and its alloys. While a little rust might not seem like a big deal, its presence can actually be a harbinger of severe damage to your metal roof panels if not caught early, or ideally, stopped before it ever has a chance to start.
The issue is most prevalent on R-panel roofs due to the use of exposed fasteners. And even with standing seam roofs, which use clips and are typically referred to as a concealed fastener roofs, there are exposed fasteners as well, most often at the eave, the end laps and at trim, such as ridge flash, rake trim, and high-eave trim.
Prevention
The best recommendation for any exposed fasteners (meaning they are exposed to the weather and other harmful elements), is that they should be long-life fasteners. When you don’t use long-life fasteners, they start rusting with exposure to moisture and, over time, the rust virus stretches down to the roof, causing severe and often irreparable damage.

Perhaps the game-changing solution possible to have a semblance of lifetime metal roofing screws and a roof itself is to have regular roofing maintenance. It will create a small budge in your regular expenses, but maintenance will address the smallest possible issues that can cause bigger problems in the future.
Whirlwind Steel has a great section on how to perform lifetime metal roofing screws maintenance. While it's still advisable to have roofing professionals perform the inspections, following these steps will give you everything you need to know about your roof's current condition.
Metal Roofing Screw Maintenance Basics
Sealant failures can be seen in peeling or flaking sealant, discolored sealant, and around fasteners that have come loose. Many sealants only last 20 years or so but can become damaged from roof panel and fastener movement. Plus, there is always the possibility a critter thinks it tastes good. Damage from snow and ice often reveals itself as ice dams and leakage under the roof. If the roof slope is low, the accumulation of snow or ice can cause panels to buckle. Hail, of course, can leave dents or, in the event of very large hailstones, can create holes in the panel.
Fastener gaskets have limited lifetimes. Check the manufacturer’s specifications for replacement schedules. Otherwise, check for tightness, discoloration or corrosion, and breakage. (Continued)
