How do I build a roof that doesn’t collapse under its own weight?

Building a sturdy roof in Valheim requires understanding the game''s structural integrity mechanics. Every building piece, including roofs, has a stability value that decreases the further it is from a foundation or support structure. If a piece''s stability drops too low, it will collapse. To prevent this, you must ensure your roof is properly supported by walls, beams, or other structural elements.\n\nStart by laying a strong foundation. Use core wood or stone for the base, as these materials provide better stability than regular wood. Core wood can be obtained by chopping down pine trees in the Black Forest biome, while stone is abundant in most biomes. Place vertical support beams at regular intervals to distribute the weight of the roof evenly. These beams should extend from the ground or a solid foundation to the height of your roof.\n\nWhen constructing the roof, use angled pieces like thatch or wood roof tiles. These pieces are lighter and easier to support than flat pieces. Begin by placing the lowest row of roof tiles along the edges of your structure, ensuring they are connected to the support beams. Gradually build upward, overlapping each row slightly to create a seamless look. Avoid extending roof pieces too far horizontally without additional vertical supports, as this can cause instability.\n\nFor larger structures, consider adding crossbeams or horizontal supports beneath the roof. These can be crafted using core wood or regular wood and placed between vertical beams to reinforce the structure. If you''re building in a biome with harsh weather, such as the Mountains or Plains, use stronger materials like stone or iron-reinforced wood to withstand environmental damage.\n\nA common challenge is building wide roofs without collapse. To solve this, divide the roof into smaller sections by adding internal support beams or pillars. For example, if you''re building a longhouse, place a row of vertical beams down the center to support the roof''s weight. This technique also works for circular or dome-shaped roofs, where central pillars can provide the necessary stability.\n\nFinally, always test your roof''s stability as you build. If a piece turns red when placing it, it means the structure is unstable and will collapse. Remove the piece and add more supports before continuing. Use the hammer''s repair function to fix any damaged pieces caused by instability.\n\nPractical tips: Use the hoe to level the ground before building to ensure a flat foundation. For multi-story buildings, stagger your support beams to distribute weight evenly. In the Meadows biome, wood is sufficient for most roofs, but in harsher biomes, upgrade to stone or iron-reinforced wood for durability. Always plan your roof design before building to avoid costly mistakes.
