During the metal roofing process, expect the removal of the old roof, preparation of the roof deck, installation of insulation (if needed), and the placement of the metal panels or shingles. The process may take several days, depending on the roof size and complexity.  In some cases the Metal roof panels can be put over an existing roof system but it may not be acceptable to local building codes and it’s better to start with new substrate so you don’t cover up previous damage or dry rot that could cause premature roof failure from underneath the metal.

Metal roofs can last 40-70 years, depending on the material quality, installation, and environmental conditions. This is significantly longer than the lifespan of traditional asphalt shingle roofs.

Routine maintenance for metal roofs includes regular inspections, cleaning debris, ensuring the gutters are clean and functional, and checking for any signs of damage or corrosion.

Common roof cleaning methods include:

  • Pressure Washing: Suitable for certain types of roofs, but can damage shingles if not done correctly.
  • Soft Washing: Uses a lower pressure and a high volume of water with a mixture of cleaning solutions to remove growths without damaging the roof.
  • Chemical Cleaning: Involves applying chemicals designed to kill moss, algae, and lichen without the need for high-pressure washing.
  • Moss Cleanup/Proofing: To clean a roof with moss, it’s often recommended to apply a moss-killing product and then gently remove the dead moss by brushing or low-pressure washing, followed by preventive treatments to inhibit future growth.

Before installing a metal roof, consider the initial cost, the noise level during rain and hail (which can be mitigated with proper insulation), and the style and color options to match your home’s aesthetics.

Steel and metal roofing offer durability, energy efficiency, fire resistance, and minimal maintenance. They can also be recycled, making them an environmentally friendly option.

A metal roof’s ability to last a lifetime is not a gimmick. With proper installation and maintenance, metal roofs can indeed last for decades, often outliving the buildings they cover.

Metal roofs seldom need to be replaced if installed correctly and maintained well. Their long lifespan means they can last as long as the house itself, barring any severe damage.

Roof cleaning is crucial for maintaining the appearance and longevity of your roof. It prevents the buildup of harmful substances like moss, algae, and lichen, which can cause roofing materials to deteriorate over time. Regular cleaning can also improve your home’s curb appeal and potentially increase its value as well as ensure the Manufacturer’s or Workmanship warranty isn’t voided due to lack of maintenance.

Proper insulation under a metal roof involves using materials that will reduce heat transfer and prevent condensation, which could lead to rust or damage to the roof structure. Spray foam insulation, rigid foam boards, and radiant barriers are commonly used.
