Beyond Roof Leaks: Other Problems That Call For Metal Roof Repair

Punctures on metal roofs can be frustrating, but that is not the only thing to worry about if you have a metal roof. The following are other metal roof problems that call for professional repair.

Rust or Corrosion

Rust and corrosion can discolor your metal roof and degrade your curb appeal, but aesthetics aren't the only concern on corroded metal roofs. The rust or corrosion eats into the metal and reduces its thickness. A rusty or corroded metal roof is, therefore, more likely to leak or get damaged than a comparable metal roof free of rust and corrosion.

Loose Panels

Loose metal panels are a precursor to further roofing problems. For one, the loose panels can be really noisy when it rains, snows, or when the wind blows across the roof. Secondly, the loose panels can also get ripped off the roof by wind and extend the damage to other parts of the roof. Lastly, the loose panels can also allow water to seep under them and leak or cause insulation and underlayment damage.

Loose or Missing Nails

The nails attach the metal panels to the roofing to the decking, which means missing nails weaken the connection between the metal panels to the rest of the roof. A strong wind can easily rip the panels off the roof if they are not fastened strong enough. Nails might miss if they were not fastened in the first place, if you used the wrong nails for the panels, or if the roof decking is rotten.

Damaged Flashing

Flashing materials, typically metal, are used to seal connections between different sections of the roof. For example, metal flashing is used between the chimney and the roof to prevent water from seeping into the roof. Therefore, damaged flashing can lead to roof leaks, so you need to fix it as soon as possible.

Faded Finish

Metal roofing panels are treated to improve their aesthetics and to prevent rust and corrosion. The metal finish also protects the metal from ultraviolet rays from the sun, which accelerates material degradation. Thus, while a faded metal finish might not be an emergency, fading can lead to corrosion and its associated problems if you don't intervene.

As you can see, the durability of metal roofs doesn't mean that they are free from problems. Regular maintenance of your roof should help you get rid of some of the problems. Consult a residential roofing professional if your metal roof starts to show signs of problems.
