Imagine waking up in the middle of the night to the unwelcome sound of dripping. Roof damage, whether from a fallen tree limb, a severe storm, or simply age, is a homeowner’s nightmare. A compromised roof can lead to extensive water damage inside your home, fostering mold growth, ruining insulation, and weakening structural supports. These problems can be incredibly expensive to fix, making immediate action crucial to minimizing the long-term impact.
That’s where a tarp comes in. Properly tarping a roof is a critical first step in protecting your home from further damage while you wait for professional repairs. It’s a relatively inexpensive and effective way to create a temporary barrier against the elements, preventing additional water intrusion and safeguarding your belongings. Knowing how to tarp a roof can literally save you thousands of dollars and a significant amount of stress.
But how do I actually tarp a roof?
What size tarp do I need for my roof leak?
To determine the right tarp size, measure the affected roof area and add at least 4 feet to each dimension to allow for overhang and secure anchoring. This extra material provides sufficient surface area to wrap around the edges of the roof and create secure points for fastening, preventing wind and rain from getting underneath.
Consider the shape of the leak area. For simple square or rectangular sections, measuring the length and width is straightforward. However, for more complex shapes or leaks near roof features like chimneys or vents, it’s best to overestimate and choose a tarp that provides ample coverage. It’s always better to have a larger tarp that you can trim or fold than one that’s too small to adequately protect the area. Pay close attention to the roof’s pitch; steeper roofs require larger overhangs for secure attachment. When selecting your tarp, also consider its material and durability. A heavy-duty, waterproof tarp made of polyethylene is generally recommended. The thickness of the tarp is measured in mils; a higher mil rating indicates a thicker and more durable tarp. For temporary roof repairs, a 6-mil or higher tarp is a good choice. Always inspect the tarp for any tears or damage before installation to ensure its effectiveness.
What’s the best way to overlap tarps on a roof?
The best way to overlap tarps on a roof is to create a shingle effect, overlapping each subsequent tarp downhill by at least 6-12 inches. This ensures water flows over the seams rather than seeping through, preventing further water damage inside your home.
When overlapping tarps, always start at the highest point of the roof and work your way down. This mimics the way shingles are laid, providing the most effective barrier against rain and other elements. Secure the uppermost tarp first, then position the next tarp so it overlaps the bottom edge of the first. The amount of overlap is crucial; too little, and water can easily find its way underneath. Use sturdy materials like roofing nails or staples (if appropriate for your tarp and roof type), along with furring strips or wood battens, to create a secure fastening system. The use of durable tape designed for outdoor use and tarps can also help to seal the seams, providing an additional layer of protection. Consider the weather conditions when installing the tarps. Windy conditions can make it difficult to position and secure the tarps properly. Ensure all edges are securely fastened to prevent the wind from lifting the tarps and potentially causing further damage. Regularly inspect the tarps, especially after storms, to ensure they remain securely in place and the overlaps are still effective. Remember that a tarp is a temporary solution, and professional roof repair should be scheduled as soon as possible to permanently address the damage.
Can I tarp a roof in windy conditions?
Tarping a roof in windy conditions is extremely dangerous and strongly discouraged. The wind can easily catch the tarp, turning it into a sail and potentially pulling you off the roof or causing severe injury. Prioritize your safety and wait for calmer weather to tarp the roof, or hire a professional roofing contractor experienced in handling tarps in challenging conditions.
Attempting to tarp a roof in high winds presents multiple hazards. Not only does the wind create a significant risk of falling, but it also makes it nearly impossible to secure the tarp effectively. A poorly secured tarp can be ripped away by the wind, leaving your roof exposed and potentially causing further damage to your property and surrounding areas. The flailing tarp itself can also become a dangerous projectile. If you absolutely must attempt temporary coverage in moderately windy conditions (and we still advise against it), proceed with extreme caution and enlist the help of several people. Use heavy-duty tarps and high-quality roofing nails or staples. Secure the tarp incrementally, focusing on creating multiple points of strong attachment to resist wind uplift. Remember that even with these precautions, the risk remains high. It’s always best to err on the side of safety and wait for calmer weather or call a professional.
What type of tarp material is most durable for roof protection?
Polyethylene (poly) tarps with a high mil thickness and reinforced weave are the most durable and reliable option for roof protection. These heavy-duty tarps offer the best combination of tear resistance, water resistance, UV protection, and longevity when properly installed and secured.
For temporary roof repairs, a heavy-duty polyethylene tarp is generally superior to canvas or vinyl options. While canvas is breathable, it’s less water-resistant and prone to mildew. Vinyl tarps are strong but can be expensive and less flexible in cold weather, making them harder to work with on a roof. A higher mil thickness (e.g., 12-mil or higher) indicates a thicker, stronger tarp. The weave count also matters; a tighter weave provides greater resistance to tearing and punctures. Look for tarps with reinforced edges and grommets to provide secure anchor points for fastening. When selecting a poly tarp, consider the color as well. Silver tarps reflect sunlight effectively, helping to keep the underlying structure cooler, which can be advantageous in hotter climates. Blue tarps are a common, more economical choice, but offer less UV protection. Darker colored tarps should generally be avoided due to heat absorption. Ultimately, choosing a high-quality, heavy-duty polyethylene tarp will provide the best long-term protection for your roof against the elements until permanent repairs can be made.
How long can a tarp stay on my roof before it needs replacing?
A tarp is a temporary solution, and ideally, it should be replaced as soon as possible with permanent repairs. Generally, a tarp should not remain on your roof for longer than 30 to 90 days. The exact lifespan depends on the tarp’s quality, weather conditions, and how well it’s installed.
A tarp’s vulnerability increases with exposure to the elements. Sunlight, especially UV radiation, degrades the tarp material, making it brittle and prone to tearing. Strong winds can loosen the tarp, causing it to flap and potentially damage the underlying roof structure or detach completely. Rain and snow can accumulate, adding weight and stress to the tarp and its anchor points. Therefore, regular inspections are crucial. Look for signs of wear and tear, such as rips, tears, frayed edges, or loose fasteners. High-quality, heavy-duty tarps will generally last longer than cheaper, lightweight options. Proper installation is also key. Securely fastening the tarp with appropriate anchors and ensuring proper overlap can significantly extend its lifespan. However, even the best tarp, professionally installed, is not a substitute for a permanent roof repair. Treat the tarp as a short-term fix while you arrange for a professional roofing contractor to assess the damage and perform the necessary repairs. Prolonging the use of a tarp can lead to further damage to your roof and potentially more costly repairs down the road.
How do I prevent water from pooling on the tarp?
The best way to prevent water from pooling on a tarp covering a roof is to create a sloped surface. This allows gravity to naturally drain the water away from the covered area. This can be achieved by ensuring the tarp is tightly secured and has a high point where the water can run off.
To ensure effective water runoff, consider the existing roof structure. If possible, use existing high points on the roof like ridges or chimney flashings as anchor points to elevate sections of the tarp. If the roof is relatively flat, you can strategically place boards or even rolled-up towels underneath the tarp to create artificial slopes. Always prioritize securing the tarp properly. Using enough nails, screws, or weights, especially along the edges and at any points where the tarp sags, will maintain the intended slope and prevent the tarp from shifting and creating new pooling areas. Furthermore, regularly inspect the tarp, especially after rainfall. Look for any areas where water is beginning to accumulate, and make adjustments as needed. This might involve tightening the tarp, adding additional support underneath, or redirecting the runoff path. Think of the tarp as a temporary roof, requiring similar considerations for water management as a permanent one.
