Three Crucial Guidelines for Preserving Metal Roofing and Prolonging Its Lifespan

Posted on: 6 November 2017


Metals such as galvanised steel, stainless steel and copper are structurally resilient, mechanically stable and highly durable. Therefore, roofing systems fabricated from these materials will provide service long after installation. However, the specific duration over which these structures will function optimally will depend on your maintenance practices. In simple terms, if your metal roofing is neglected or treated poorly, you will notice significant signs of failure before the predicted end of its lifespan. Here are some simple tips to help you preserve your roofing and extend its service life.

Minimise Accumulation of Debris

One of the common causes of premature failure of metal roofs is the stress caused by accumulated debris. In general, if the metal sheets or panels have to support the weight of accumulated debris, they will become strained. The continued pressure can cause the structural joints to fail and separate. Eventually, leaks will occur. Therefore, you should dedicate time to clearing the roof. You can use an extendable brush to sweep off the leaves and debris. Also, you should keep an eye on snow during winter months. If too much snow builds up on the roof, you should consider clearing it to prevent mechanical stress from the weight.

Prune or Remove Nearby Trees

Metal roofs will sustain severe damage if they are in constant contact with dangling tree branches. These overhanging limbs will cause abrasion of the roof as the wind causes them to sway. This friction will ruin the aesthetics of the roofing surface by scratching off the finish. The damage to the finish can be highly detrimental for galvanised steel roofs because they are susceptible to rust. Additionally, the sheet metal could also get torn by broken or flying branches during storms. Therefore, you should trim trees which are close to your roof on a regular basis. Alternatively, you can remove the pertinent tree.

Limit the Flow of Foot Traffic 

Metal roofs are resilient and can support human weight. However, you should remember that they are not meant for foot traffic. If you or other people step on the structure regularly, the structure will weaken over time. The damage can be unusually extensive if the person on the roof does not know the areas with supporting frames or trusses underneath to hold their body. For the best results, you should perform maintenance work from an elevated platform. If the roof must be inspected or repaired, you should engage an experienced roofing contractor to prevent further damage to the structure.
