Ignoring what you might think is minor roof damage or even undetected damage can lead to major water leaks in the future. Water leaks inherently damage the roof itself, as well as your home's insulation, structure and your posessions.. Although metal roofs wear extremely well, they have unique characteristics that can lead to major damage if not properly maintained and inspected. A major difference between a metal roof and a traditional shingle roof is that metal roofs are designed for flowing water, meaning there should never be any standing water on the roof for any length of time.


It is recommended to have a trained roofing technician perform a thorough inspection of your metal roof at least twice per year. This can save you alot of money and headache by not waiting until "it's too late".

These are the most common issues with metal roofs:

  1. Surface Rust – Surface rust can become a major problem if left untreated.  Most metal roofing is made of galvanized metal or has a coating to prevent rust from developing. However standing water or heat from direct sunlight can both wear the roof’s protection away over time. By having your roof regularly inspected, you may be able to prevent and developing rust spots from worsening by using a proper rust inhibitor.

  2. Deflection – Bent panels can lead to standing water on your metal roof, which can cause rust and leaks.

  3. Movement – A metal roof should be designed to move, allowing for water to flow off of it. If a repair product is used that doesn’t allow for proper flexibility, the panels will continue to move but the patch will not, causing more issues than the original roof leak.

  4. Punctures – Punctures often occur due to heavy foot traffic on the roof, such as during construction, maintenance or HVAC equipment installation. For those who need access to the roof, specific walkways and guidelines should be in place to not crimp panels and to stay a safe distance from skylights. Also, equipment should never be dragged across a metal roof. Sharp objects falling onto your roof can also contribute to punctures. Caulking can be used to fix punctures but should only be considered a temporary fix.

  5. Incompatible metals – There are many types of metal roofs, such as copper, steel, stainless and galvanized metal. However, not all metals perform the same; and some are incompatible when used together. Specific materials should be used for metal roofs so that corrosion and rust do not occur. Dissimilar metals will cause a negative reaction when situated together, which can cause cracking, rust spots and prohibit water flow. Your metal roofing provider should be well-informed on metal compatibility issues to help you prevent problems from occurring.

  6. Fastener issues – There are two types of metal panel attachments – clips and fasteners with rubber washers. Clips fasten to the purlin, and the fasteners are concealed once the metal laps on the panels are seamed or crimped together with generally a sealant underneath. Fasteners with rubber washers are self-drilled approximately every two square feet. Over time, these fasteners back out and leave holes or gaps between the metal and the rubber washer where they were once installed, which opens the roof to water intrusion.
