How to Protect Rural Self-Built Houses from Typhoons: Roof Reinforcement Methods
TyphoonSays·防御问答 · Security Rescue · 更新 at 2026-10-18
Early Warning Response and Elimination of Peripheral Hazards
Rural self-built houses often represent a weak link in typhoon defense due to significant structural variations and long maintenance cycles. Once meteorological authorities issue a Blue Typhoon Warning or higher, defensive measures should be immediately activated (specific standards for school and work suspensions are subject to local government announcements). The primary task is to clear obstacles from "wind corridors": thoroughly remove flower pots, debris, and temporary structures from roofs, balconies, and courtyards. Trim trees near the house, removing dead or diseased branches to prevent them from breaking and shattering tiles or glass. Additionally, comprehensively check the sealing of doors and windows. It is advisable to install wooden board supports for old wooden windows, and apply tape in a "rice" character pattern on glass windows to increase toughness and reduce the risk of shattering and flying debris.
Categorized Roof Reinforcement: From "Anti-Lift" to "Drainage"
The roof is a critical area for wind resistance. Different materials require targeted measures, with the core focus on enhancing overall connectivity and resistance to wind uplift.
- Tile Roofs: Focus on inspecting loose or missing tiles and re-fix them using cement mortar. For roofs with steep slopes, it is recommended to install wind-proof hooks or battens at the eaves to block the path of strong winds climbing up the roof surface and lifting tiles. If conditions permit, lay a waterproof breathable membrane under the tiles to assist with drainage and buffer direct wind pressure impact.
- Color Steel/Corrugated Iron Roofs: These roofs are highly susceptible to being lifted off entirely. Each fixing screw must be checked individually; replace rusty or loose screws with self-tapping screws equipped with waterproof washers, and appropriately increase the density of fixing points. A more effective approach is to use angle steel or flat steel to create battens that span across the roof and are securely locked onto the purlins, forming a grid-like suppression structure to significantly improve wind stability.
- Concrete Flat Roofs: Although structurally stable, strict prevention of water accumulation is required. Typhoons are often accompanied by heavy rainstorms. It is essential to clear gutters, downspouts, and drains to ensure rapid rainwater discharge, avoiding long-term water accumulation that increases roof load or causes leakage, which could subsequently erode the building structure.
Material Reserve and Principles of Emergency Evacuation
Beyond hardware reinforcement, soft emergency preparedness is equally vital for survival. Households should reserve at least three days' worth of drinking water, non-perishable food, common first-aid medicines, and emergency equipment such as flashlights, radios, and power banks. During thunderstorms and strong winds, it is recommended to cut off non-essential power supplies to prevent fires caused by short circuits.
Special caution is required: if new cracks appear in the walls, tilting intensifies, or the roof suffers severe damage during typhoon landfall, do not blindly attempt risky repairs. Wind forces are extremely strong at this time, making outdoor work highly dangerous. Immediately take important documents and an emergency kit, and evacuate to sturdy public shelters or the homes of relatives and friends. Always remember that "life comes first." Property losses can be compensated later, but personal safety cannot be regained. Continuously monitor official meteorological information, do not believe or spread rumors.
