Roofs are the part of a building that are most exposed to intense elements – fluctuating temperatures, powerful sunshine, hail, rain, or even strong wind uplift – all of which gradually damages a roof over time. The lifespan of a roof depends on the type of material used, climate, orientation and other factors. The average roof can last anywhere from 15-30 years, whereas the average building lasts between 50-100 years – meaning that every building will need at least one roof replacement or repair in its lifetime.

Metal Roof Repair

Metal roofs are one of the longest lasting roof systems but still are frequently in need of repair. Older metal roofing may need repair due to:

  • Metal corrosion
  • High metal expansion and contraction over time, leading to loose fasteners and cracks in seals and joints
  • Condensation
  • Storm damage
  • Leaks related to the waterproofing of difficult details, joints and connections or poor installation (especially at areas such as inner gutters, sky-lights etc.)
