Roofing: Behind the “Sheets,” Part 4

The final element we’re talking about is drainage.

  • When you really go back to the roots as to why people started to have roofs over their heads, you would see that it was mainly to keep themselves dry from the rain. Which is why the drainage aspect of roofing should never be overlooked. A leaky roof can spell disaster for the entire house. It can cause rapid deterioration of your insulation, damage to your support beams and can cause the stuff in your house to get wet—which is quite ironic since you’ve purposely put a roof over your head to keep yourself and your belongings dry.
  • Drainage in roofing would comprise of the pipes that bring the water from the roof to the ground, the  materials used in repelling the water, and even the pitch of the roof (or the steepness of the roof). The pipes have to be structured in a way (using eaves, drainpipes, and waterspouts) that it would carry the water away from the roof and down to the ground without compromising the house’s overall structure. It should be kept away from the walls as they might seep in and cause damage to the structure.
  • The materials used for the roof are also quite essential in repelling water. Most house-builders would recommend metal roofs for places with high amounts of rainfall. Metallic surfaces are smooth, unlike wood shingles and concrete tiles, so they prevent accumulation of water in pockets. This property, along with an increased steepness of the roof, would mean the more expedient repulsion of rainwater. A great relief for those who fear the troubles of water damage.
