Weather can wreak havoc on a construction site, costing real estate investors, rehabbers, developers, and fix-and-flippers time and money. According to the National Oceanic and Atmospheric Administration (NOAA), weather-related delays cost the U.S. construction industry $4 billion annually. Don’t let storms derail your project—here are 5 strategies to weatherproof your site and keep your timeline and budget intact.

1. Secure Materials Against Wind and Rain
   High winds can scatter materials, and rain can ruin drywall or lumber. The American Society of Civil Engineers notes that winds over 40 mph can lift unsecured items.
   Action: Use heavy-duty tarps ($20-$50 each) and tie-downs to cover materials. Store smaller items in weatherproof containers or a locked shed to prevent theft and damage.
2. Implement Erosion Control Measures
   Heavy rain can wash away topsoil, leading to fines—EPA penalties for erosion violations start at $37,500/day.
   Action: Install silt fences ($2-$5/linear foot) around the site perimeter and seed temporary grass to stabilize soil. Schedule grading during dry seasons to minimize risk.
3. Protect Open Structures with Temporary Roofing
   Unfinished roofs leave interiors vulnerable to water damage, which can cost $5,000-$15,000 to repair.
   Action: Use temporary roofing systems like shrink-wrap or tarps (around $500 for a small site) to cover exposed areas. Ensure proper drainage to avoid pooling.
4. Plan for Flood Prevention
   FEMA reports that 20% of flood claims come from areas outside high-risk zones, so no site is immune.
   Action: Check FEMA flood maps (msc.fema.gov) to assess risk, then elevate critical equipment on blocks or pallets. Dig temporary drainage channels to redirect water away from the site.
5. Monitor Weather and Adjust Schedules
   Unexpected storms can halt work for days, with each delay costing $1,000-$5,000 in lost productivity for a small project.
   Action: Use apps like Weather Underground to track forecasts. Schedule weather-sensitive tasks—like concrete pouring—during clear windows, and have a backup plan for indoor work.

Takeaway: Weatherproofing your site isn’t just about protection—it’s about profitability. By planning ahead, you’ll avoid costly delays and keep your project on track. As a hard money lender we have seen it all so feel free to always reach out to us for any real estate project advice!
