Key Signs You Need Metal Roof Repair

Posted on: 7 July 2023

Metal roofs are durable, long-lasting, and have a wide range of benefits. They are energy efficient, low maintenance, and resistant to fire, wind, and pests. But just like any other roofing material, metal roofs are also prone to damage, wear, and tear over time, especially if they are exposed to harsh weather, extreme temperatures, and other external factors.

To help you get ahead of any potential problems, here are some key signs that your home may need metal roof repairs.

Rust and Corrosion

Metal roofs are prone to rust and corrosion, especially if they are made of steel or some other metal alloys. Over time, exposure to moisture, rain, snow, and other elements can cause rust and corrosion to spread and weaken the metal.

Rust is basically iron oxide, which forms when metal is exposed to oxygen and moisture. Corrosion is also a common issue, which happens when an electrochemical reaction occurs on the metal between two different metals or between metal and oxygen. The result is a thin, powdery substance that can weaken the material and lead to leaks.

If you notice rust spots, discoloration, or signs of corrosion on your metal roof, be to address them immediately. Depending on the severity of the damage, an expert may need to replace the affected panels or apply a protective coating to prevent further corrosion.

Leakage and Water Damage

Leakage is a common problem that affects metal roofs, especially if they are installed incorrectly or develop gaps, cracks, or holes. Usually, the leaking happens near the seams, flashings, and other areas where two panels overlap.

Leaking can cause water damage to your roof and home, leading to costly repairs and potential health hazards. Some leaks even allow moisture and condensation to seep in, which can cause mold and mildew growth on the roof. You may also notice water dripping or pooling on the roof or around the gutters, which can cause water damage to your property and pose a safety hazard.

Fixing a roof leak requires identifying the source of the problem, sealing the damaged area or replacing the affected panels, and inspecting the rest of the roof for potential leaks. But that's something that only a professional roofer should do to ensure long-lasting results.

Loose or Missing Fasteners

Metal roofs are typically attached to the roof deck with screws, bolts, or other fasteners that hold the panels in place. Over time, these fasteners can come loose or fall off due to wind, expansion and contraction, or improper installation. Unfortunately, missing fasteners can lead to serious problems such as loosening of the panels, water leakage, and sagging.

If you notice gaps or spaces between the panels, loose screws or bolts, or missing fasteners, it's a sign that your roof is not well-secured. Loose panels can also make noise, vibrate, or flap in the wind, causing damage to the panels or the roof deck.

Fixing loose or missing fasteners may require tightening the screws or bolts, replacing the missing fasteners, or securing the panels with additional fasteners. In some cases, you may need to replace the entire panel or section of the roof to solidify the stability and integrity of your metal roof.
