Tips for Metal Roof Maintenance
Metal roofs are durable, energy-efficient, and relatively lightweight, which minimizes structural damage. Like other roofing material, however, you will only enjoy the benefits of your metal roof if you take good care of it. Fortunately, caring for a metal roof is relatively simple. Below are the major maintenance measures to take.
Trim Trees Around the House
Tree branches around the house can damage the roof. The branches can rub against the metal and erode the finish. The erosion will expose the metal to weather elements, such as moisture, which increases corrosion risk. Tree branches can also break and puncture the roof, especially during storms.
Trim the trees regularly so that they are always a safe distance from the roof. Cut down dangerous trees or tree branches, such as dry or leaning trees, before they fall on the roof.
Keep the Roof Clean
All roofs need to be clean, but debris has different effects on different roofing materials. For metal roofs, accumulated debris can trap moisture and encourage corrosion. The risk is especially high in old roofs or roofs with damaged finishing. Some of the debris, such as tree twigs, can also scratch the metal surface and damage the paint or finishing.
Clean the roof regularly to prevent such damages. The frequency of cleaning depends on the level of debris in your area. For example, frequent cleaning is necessary if you have many trees in the neighborhood that deposit leaves on the roof.
Minimize Foot Traffic
The profiles of metals used for roofing is relatively thin. A metal roof can deform if you subject it to excessive weight, such as by walking on it. For example, walking on the roof can create dents that can allow water to pool and damage the roof. Friction from foot traffic can also damage the finishing.
Minimize foot traffic on your metal roof to avoid such damages. If you have to walk on the roof, such as for repairs or inspections:
- Wear soft-soled shoes to minimize friction
- Walk close to the decking
- Avoid the ribs or laps
Note that infrequent walks on the roof are acceptable — only frequent foot traffic should worry you.
Avoid Repairs With Dissimilar Metal
Galvanic corrosion occurs when two dissimilar metals touch, especially in the presence of moisture. The corrosion occurs when one metal loses some of its irons to the other.
Galvanic corrosion can weaken your roof and lead to damage. Therefore, don't let dissimilar metals touch on your metal roof. For example, if you want to replace the flashing or install something on the roof, ensure it is of the same metal as the roof or use a nonmetallic buffer between them.
Watch Out for Paint Overspray
Paint overspray can cause cosmetic damage to your roof. Ensure paint doesn't spread to the roof — especially when painting parts of the house that are close to the roof, such as the eaves. A practical precaution is to use rollers or brushes when painting close to the roof. The two techniques are less dangerous compared to sprayers.
Regularly Inspect the Roof
Your metal roof can still suffer damage despite your best precautions. Inspect your roof regularly to spot emerging problems before they worsen. Watch out for:
- Corrosion
- Dents
- Deep scratches
- Loose or missing fasteners
- Metal holes or tears
Most roofs can benefit from semi-annual inspections. Get professional repairs for any problems the inspections might reveal.
Maintenance will prolong your metal roof's lifespan, but you will eventually have to replace it. When that time comes, choose an experienced, skilled, and professional roofing contractor.
