omdekning

Omdekning is a Swedish term that translates to "re-roofing" or "roof replacement" in English. It refers to the process of removing an old roofing material and installing a new one on a building. This is a significant undertaking that is typically done when the existing roof has reached the end of its lifespan, has suffered damage, or when an upgrade in material or performance is desired.

The decision to undertake omdekning is usually prompted by visible signs of wear and tear such as missing or damaged shingles, sagging sections of the roof, or leaks. Beyond addressing immediate problems, re-roofing can also improve a building's energy efficiency, aesthetic appeal, and overall structural integrity. Modern roofing materials often offer better insulation properties and durability compared to older options.

The process itself involves several stages, beginning with the removal of the old roofing layers, including underlayment and flashing. The roof deck is then inspected for any rot or damage, and repairs are made as needed. New underlayment is installed, followed by the chosen roofing material, such as asphalt shingles, metal panels, tiles, or even green roofing systems. Finally, flashing around chimneys, vents, and valleys is replaced or repaired to ensure water tightness. The complexity and cost of omdekning can vary greatly depending on the size and pitch of the roof, the type of material used, and any necessary structural repairs.
