2 Popular Roof Categories That May Surprisingly Fail You

1. Clay & Concrete Roofs

  • Did you know that clay and concrete roofs may raise roof costs and may mean more maintenance compared to GERARD?
  • They are very heavy roofing solutions. They can be 7-times (!) heavier than GERARD. It means you may spend less on the roofing tiles but the strong roof structure increase expenses for you.
  • More maintenance is required from you in the long run if you decide for these traditional tiles. High wind can lift up the tiles, making the tiles loose – and dangerous for people walking around – or can even blow them off the roof. Then you need to take care of replacing them.
  • They can crack in freezing temperatures. It means they may be unable to prevent leakages on your roof and you need to replace them.
  • Can be broken by extreme hail, which climate change may bring more often. Several houseroofs were destroyed in a hailstorm in Slovenia, on 8th June 2018 in Crnomelj municipality, where hails were as big as an apple (10 cm in diameter). GERARD roofs were not penetrated though.

  • The colour of your roof can fade with time if it is applied only to the surface of the tile.


2. Longrun

Did you know that painted metal longrun roofs are much noisier than stonechip coated GERARD roofs?

  • Poor noise reduction is due to the paint and installation technique. As demonstraded on the graph below GERARD is nearly as quiet as a concrete tile. Because of the textured stonechip coating and the special interlocking installation method.

  • Leakage risks are present due to the installation method used for long runs, which are not interlocking like GERAD. Furthermore, due to the fact that with changing temperature their dimension can change as well.
