Metal Roof Over Existing Roof in Doral

Metal roofing and fabrication in Doral, Florida, must contend with the persistent challenges of a subtropical climate. This includes high humidity, intense sun exposure, and the corrosive effects of coastal salt air, even for properties slightly inland. The region also faces significant hurricane exposure, requiring robust materials and installation methods to withstand high winds and driving rain.

What to keep in mind locally

  • Ensure proper material selection and coatings to resist salt corrosion and UV degradation.
  • Verify that installation meets or exceeds wind-load requirements for hurricane zones.
  • Consider ventilation strategies to manage high humidity and prevent condensation within structures.
  • Evaluate the existing building structure for compatibility with metal systems, especially in older construction.

What the work involves

The process begins with inspecting the existing roof to ensure it is structurally sound and free of significant damage. If suitable, a layer of underlayment is applied, followed by the installation of the new metal roofing panels, which are typically fastened to the existing roof deck or to a newly installed purlin system.

When this comes up

  • When the existing roof has reached the end of its lifespan and requires replacement.
  • When the existing roof’s structure is deemed sound enough to support an additional layer.
  • When a building owner seeks to add the durability and longevity of a metal roof without the cost and disruption of a full tear-off.
  • When local building codes permit the installation of a metal roof over an existing layer.
