The short answer

Assessing Damage Safely

Before you attempt any temporary protection, you need to assess the damage safely. Do not climb onto a wet or unstable roof. Instead, use binoculars to view the roof from ground level. Look for displaced shingles, visible holes, or areas where the roof decking might be exposed. Clear the immediate area of any fallen debris to prevent further hazards.

Understanding the scope of the damage helps you plan your temporary cover. If you see a large hole or a significant section of the roof is missing, your tarp will need to be much larger. Note any overhead hazards like damaged tree limbs or dangling power lines. If you see any power lines on the roof, contact your utility company immediately and do not approach.

Choosing and Placing a Tarp

Select a heavy-duty, waterproof tarp designed for construction use. Polyethylene tarps, often blue, are a common option. The tarp must be large enough to cover the damaged area and extend at least four feet over the roof's ridge line. This over-the-ridge method is crucial, as it prevents water from pooling and seeping under the tarp's edges during rain.

Lay the tarp flat on the ground to unfold it and identify its orientation. Carefully lift the tarp onto the roof, ideally with a helper. Drape it so the longest side runs up and over the peak. The goal is to have an even amount of material on both sides of the damage, creating a sloped surface that sheds water away from the compromised area.

  • Use a tarp at least 6 millimeters thick for durability.
  • Secure the top edge first, over the ridge of the roof.
  • Fasten the tarp using 2x4 wooden boards screwed into the roof deck.
  • Place sandbags or additional weighted objects along the tarp's lower edges.
  • Avoid using nails alone, as wind can rip the material.
  • Check all securing points twice to ensure they are tight.

Securing the Temporary Cover

The key to a successful temporary cover is preventing wind from getting underneath it. After draping the tarp over the ridge, place wooden boards along its top edge on both sides of the roof. Screw these boards directly into the solid roof decking, not just the shingles. Use screws long enough to penetrate the decking, creating a solid anchor point that resists uplift.

Work your way down the sides, adding more boards to secure the tarp's perimeter. Space the boards every two to three feet for even hold. On the lower edges, you can use more boards or heavy objects like sandbags or concrete blocks. Do not rely on duct tape or bungee cords, as they will fail quickly in wind and rain.

Monitoring for Interior Water

Even with a well-secured tarp, some water may still find a way inside. Place buckets or plastic containers under any active drips in your attic or living spaces. Move furniture and valuables away from the affected area. If you have water-damaged flooring, removing rugs and lifting furniture onto blocks can prevent secondary damage and make the eventual cleanup process simpler.

Monitor the condition of the tarp and the interior daily. High winds can loosen even well-secured covers. Check for new water stains on ceilings or walls, which indicate the tarp has failed or the leak has shifted. In Baltimore's humid subtropical climate with hot humid summers and cool winters, trapped moisture can lead to mold quickly, so vigilance is important.

Arranging Permanent Repairs

A tarp is only a short-term solution, often lasting a few weeks at best. Contact a qualified roofer to assess the damage and provide a repair plan. Discuss the scope of work and get a clear understanding of the timeline and materials needed. If the damage is extensive, you may need a full roof replacement, which requires more planning and coordination.

You should also contact your insurance company to start a claim, if applicable. Take photographs of the initial damage, your temporary tarp installation, and any interior water damage. Policies vary, and your insurer decides what is covered. A permanent roof repair will seal your home and prevent the need for more extensive water damage restoration work later.

Frequently asked questions

How long will a tarp last on my roof?

A properly installed heavy-duty tarp can last several weeks, but it is not a permanent fix. High winds, UV exposure, and heavy rain will degrade the material over time. You should plan for permanent repairs as soon as possible to avoid further damage.

What if I cannot safely install a tarp myself?

If the roof is steep, the damage is severe, or you are unsure, do not risk injury. Many roofing contractors offer emergency tarping services to secure your home. This creates a safer, more reliable temporary barrier while you schedule the full repair.

Will my homeowner's insurance cover this?

Wind damage is often covered, but you must check your specific policy details. Document all damage with photos before making temporary repairs. File a claim promptly. Policies vary, and your insurer decides what is covered.
