Why You Should Think About Getting a Metal Roof Replacement

Metal roofs are one of the most maintenance free roofing systems used today. A properly installed metal roof can last many years without the need for repairs. However, this type of roofing can also be damaged by severe weather. An inspection can uncover the signs of damage or degradation of the metal roof.  Roofing contractors who specialize in metal roofs can advise on whether a replacement is necessary by assessing the extent of the damage.

How long will metal roofing last?

Metal is among the most long-lasting materials used on roofing systemstoday. This material can last an average of 40-70 years, which is way longer than common options like asphalt shingles which only last 12-20 years. The metal roof is highly resistant to strong winds and impact from hail.

When properly installed, the roof doesn’t rust. In residential roofing, a metallic rust-preventing coating is used to cover the metal sheets and a paint finish is applied. This helps to prevent corrosion.

Metal roofs can still be damaged by very strong winds, high-velocity debris, and hail. The metal panels can dent or become corroded over time. It’s important to have a professional roofer inspect the metal roof after severe weather to determine if there’s a need for replacement.

Was the metal roof poorly installed?

A common reason for metal roof failure is poor installation. Metal panels must be properly installed and securely screwed down to offer adequate protection and last for many years. If well installed, the metal roof can seal moisture so easily that problems like mold, mildew, rot and attic condensation will be almost unheard of in your property.

A poorly installed metal roof doesn’t come with all these benefits. Inexperienced contractors fail to properly secure the panels, which make them move easily during severe weather. Punctures on the panels, missing/damaged flashing and failing seaming are some of the problems, which can cause a metal roof to fail prematurely if they’re not addressed fast enough.

The installation process must be gently done to maintain the integrity of the panels. If during installation, the metal panels are scratched or gouged, it already compromises the longevity of the roofing system. Coating must be done properly on the underside of the panels to prevent corrosion and weakening over time. If the metal roof was installed directly over shingle roofing, the system is likely to fail prematurely. Failure occurs since the shingles scratch the protecting coating on the backside of the panels.

Signs that the metal roof needs a replacement

Metal roofs are virtually maintenance free. However, it’s a good idea to perform periodic inspections and watch out for common signs of degradation that could become severe over time. Among the signs to look out for include:

  • Severe leaks, tears and punctures on the metal panels
  • Extreme rust and discoloration
  • Loose nails and fasteners
  • Corrosion
  • Panels without any finish
  • Completely damaged flashing

If the metal roof is severely damaged, having it replaced can boost the value of your property and also result in huge energy savings. Reach out to a reliable contractor with extensive skill and experience in metal roofing for a replacement.
