During extreme weather events in Portland, Oregon, property owners should expect some form of damage to their buildings. One of the most common issues is unexpected roof damage, which is stressful and complicated to deal with. It becomes even more challenging when you don’t have the budget to fix the damaged roofing right away, so the next best thing is roof tarping.
Many property owners think that fixing a leaking roof is as easy as placing and nailing the tarp on the roof, but several factors must be considered to install it correctly. If you plan on learning how to tarp a leaking roof, take note of the steps below to achieve desirable results.
What Is Roof Tarping?
Roof tarping is a short-term emergency repair solution that covers a damaged or compromised roof to prevent further damage from severe weather conditions like rain, wind, or snow. This technique is often used after a roof has been damaged by storms, hurricanes, or falling debris until permanent repairs can be made.
Several Benefits of Tarping a Damaged Roof
It’s important to protect your building’s interior after severe storms and winds destroy your roofing system. While you may think a simple tarp will not work, you can find a few benefits that may change your mind:
- Prevents Further Water Damage. By covering the damaged area with a waterproof barrier, a tarp prevents rainwater from infiltrating the roof, which can lead to costly water damage inside the home, including mold, water stains, and structural issues.
- Protects Against Weather Elements. Tarps shield the roof from wind, debris, and UV rays. This protection is needed to stop the damage from worsening in adverse weather conditions, preserving the interior and structural integrity of the building.
- Temporary Insulation. While not as effective as proper roofing materials, a tarp can offer some insulation, helping maintain indoor temperatures by mitigating drafts caused by open roof areas.
- Cost-Effective Short-Term Solution. Tarping is relatively inexpensive than immediate roof repair or replacement. It allows homeowners to shield their property while budgeting and planning for more permanent solutions.
- Prevents Pests and Animals. A secured tarp can deter pests and animals from entering the home through gaps or holes in the damaged roof, which could cause more damage and health concerns.
- Maintains Home Value. By preventing additional damage, tarping maintains the home’s value and attractiveness, which is important when selling or obtaining insurance coverage.
How to Put a Tarp on a Roof: A Step-By-Step Process
For those who prefer doing the roof tarping themselves, there are specific steps to achieve proper installation. A properly installed tarp is important to prevent it from coming off due to strong winds. Here’s a detailed guide on how to secure a tarp to a roof:
1. Assessment and Safety Precautions
Begin by inspecting the extent and location of the damage. Prioritize safety during the first step, as working on a roof can be dangerous. Make sure you have the proper safety equipment, such as non-slip shoes, a safety harness, and a hard hat. It is also advisable to have a second person assist you for extra support. Evaluate weather conditions before starting, as handling this task during inclement weather can increase the risk of accidents.
2. Gather Materials and Tools
Collect necessary materials before heading up to the roof. You will need a durable, waterproof tarp that extends at least three feet beyond the damaged area in every direction. Additional materials include:
- Several 2×4 wooden boards
- Hammer
- Roofing nails or screws
- Weighted sandbags
- Utility knife
Preparing everything beforehand will lower the time spent on the roof and reduce the risk of accidents.
3. Clear Debris and Prepare the Area
When you’re on the roof, clear away debris, such as broken shingles, branches, or loose materials around the damaged area. A clean surface is crucial to fasten the tarp. Assess the surrounding roof structure to find stable and secure areas for anchoring the tarp. Remember to use a tape measure to determine the tarp size needed to cover your roof.
4. Position the Tarp
Unroll and lay the tarp over the damaged section, making sure to cover it well beyond the damaged area, as this overlap provides extra protection against wind and rain. Ideally, you need to position the tarp so that at least one edge aligns with the roof’s slope, facilitating water runoff. Double-check that the tarp is evenly spread out and lies flat, with no wrinkles or bunching that could allow water to collect.
5. Secure the Tarp
Start by securing the tarp at the highest point to prevent water from seeping under it. Lay the 2×4 anchor board along the edge and fold the tarp over it. Using a hammer, nail through the tarp and into the board to secure it to the roof. Repeat this process with the other 2×4 boards along the remaining edges, especially the bottom, to firmly anchor the tarp. Make sure the tarp is pulled taut but not overstretched to avoid rips or tears.
6. Additional Fastening
For added security against strong winds, consider placing sandbags along the edges of the tarp to weigh it down. You can also reinforce the fastening by tying the tarp down with ropes looped around the boards or through grommets in the tarp. This lowers the risk of the tarp being lifted or displaced by the wind.
7. Regular Inspection and Maintenance
Once the tarp is in place, regularly inspect it for wear or damage, especially after storms. Replace or adjust the tarp as necessary to maintain its protective effectiveness. Keep an eye on the weather and repair or replace the tarp immediately if any issues arise.
Additional Methods to Improve Your Roof Tarp
If you think that a temporary roof tarp alone won’t be able to protect your residential or commercial building in Portland, there are several ways to improve its efficiency. Enhancing the effectiveness of a roof tarp can further protect your home from the elements and extend the temporary solution’s lifespan.
Examples of additional methods to improve your roof tarp installation include:
- Use Heavy-Duty Tarps. Go for high-quality, heavy-duty tarps that are made for durability and resistance to tears. These tarps will withstand harsh weather conditions better than standard tarps, possibly lasting longer and offering more reliable protection.
- Overlap Tarps for Larger Areas. If the damaged area is extensive, consider overlapping multiple tarps. Overlap it at least 12 inches and secure it tightly to prevent water damage. Overlapping tarps cover larger areas and can reinforce weak points where tarps meet.
- Create Water Runoff Channels. Strategically place the suitably sized tarp to direct water away from the damaged area, encouraging natural water runoff. This involves angling the tarp and securing it to guide water downslope, reducing the risk of water pooling and subsequent leaky roofs.
- Seal Edges With Adhesive. Apart from using nails and boards, applying a strong adhesive or roofing sealant along the edges of the tarp can prevent water and wind from getting underneath and causing structural damage. This creates an added layer of waterproofing at vulnerable points.
- Install Wind Straps. Use wind straps or specialized tie-downs to anchor the tarp securely against strong wind forces. Strapping the tarp down at multiple points can greatly reduce the chances of it being lifted or torn apart during storms.
- Secure With Extra Weight. In windy areas around Portland, place more sandbags or weights along the tarp edges, especially around the perimeter. This added weight keeps the tarp in place without relying solely on nails or boards.
- Regular Weatherproofing Treatment. Apply a waterproofing spray or treatment to the tarp periodically. This treatment can enhance the tarp’s water-shedding capabilities, effectively repelling moisture until the permanent roof repair job.
Different Types of Tarp Materials for Roofs
Several tarp materials can be used for temporary emergency roof repairs, each with characteristics and suitable applications. Knowing the various types can help you choose one that will meet your preferences. Here are some of the common tarp types:
- Polyethylene Tarps. These are the most commonly used tarps for roofing due to their affordability and effectiveness. Made from woven polyethylene fabric, they are coated with a waterproof laminate, making them resistant to water and UV rays. They are typically lightweight, easy to handle, and come in varying thicknesses for different levels of durability.
- Vinyl Tarps. Vinyl tarps are heavier and more durable than polyethylene tarps. Made from a polyester fabric coated with vinyl, they provide excellent resistance to tearing, abrasion, and harsh weather conditions. Vinyl tarps are suitable for areas that experience strong winds or require a more robust temporary cover.
- Canvas Tarps. Made from cotton or polyester fabric, canvas tarps are breathable and suitable for moderate weather protection. Although not entirely waterproof, they are water-resistant and can be treated to improve their weatherproof capabilities. Canvas tarps are more prone to mildew and are best used for shorter durations or dry climates.
- PVC Tarps. Like vinyl tarps, PVC tarps are known for their strength and durability. They consist of a polyester base fabric coated with polyvinyl chloride. PVC tarps provide excellent weather resistance and are suitable for heavy-duty applications requiring longer-term protection.
- Mesh Tarps. While not typically used for direct roof covering, mesh tarps can be combined with other tarp materials for added wind resistance. These tarps allow air to pass through, reducing wind load, and are often used to secure other tarps more firmly in place.
How Long Can You Leave a Tarp on a Roof?
A tarp on a roof is intended as a temporary solution and should ideally not be left in place for more than 90 days. While durable tarps can provide short-term protection, they are not designed for long-term exposure to the elements. Over time, prolonged exposure to sun, wind, and rain can degrade the material, leading to possible roof leaks and additional damage.
A tarp left for too long can contribute to mold and mildew growth underneath and deterioration of the roofing materials it covers. Therefore, it is important to monitor the condition of the tarp regularly and plan for permanent repairs with roofing professionals as soon as possible. A prompt roof repair or replacement by a professional ensures its integrity and prevents additional issues.
How Do You Secure a Tarp to a Roof Without Nails?
It is possible to tarp a roof without using nails, which can be beneficial to avoid damaging the roofing materials. Some of the well-known alternative methods to securing a roof tarp without nails are:
- Sandbags. Placing heavy sandbags around the tarp’s edges provides a secure hold against wind and prevents the tarp from shifting.
- Rope Tying. Secure the tarp by tying it down with ropes. Use the tarp’s grommets to pass ropes through and anchor them to stable features like chimneys, trees, or stakes driven into the ground.
- Adhesive Strips or Tape. High-strength adhesive tape or strips can be used to attach the tarp edges to the roof. This method is suitable for short-term applications and requires selecting a tape that can withstand bad weather conditions.
- Weighted Objects. Use heavy objects, such as bricks or pavers, placed along the tarp’s perimeter to hold it in place, ensuring the objects do not cause damage to the existing roof structure.
- Compression With 2×4 Boards. Instead of nailing, place 2×4 boards over the tarp edges and use clamps or tie-down straps to hold them in place, using their weight to maintain the tarp’s position.
