Roof anatomy roof repair solutions

Roofs consist of much more that what meets the eye – the topmost layer of any roof is sustained by a complex support system consisting of multiple layers. Here is what most roofs consist of:

  • The roofing cover – asphalt shingles, wood, slate, metal panels, clay and cement tiles are the most common roof covering materials used for sloping roofs, while rubber, metal, tar and gravel and spray foam are the most common Littleton roof repair solutions used on flat roofs;
  • Underlayment – made from resistant and durable felt or polymers, this layer plays the role of keeping away any water that might seep through;
  • Sheathing – this layer consists of wooden elements, such as plywood, metal panels and boards made from various polymers and it plays the role of supporting the underlayment and the roofing cover;
  • The flashing – made from metal alloys or other, rubberized or coated materials, flashing is the term used for the stripes of material installed around roof opening, such as around skylights and chimneys as well as in areas where two roof sections are joined, such as in roof valleys. The flashing on your roof plays the role of waterproofing and strengthening the roof in areas where its continuity has been broken.
