Is Roofing in the Rain Bad? (Why You Shouldn’t)

The rainy season is here, and if you’re a roofer, that means you’re probably thinking about getting up on a ladder in the rain.

Let’s take a look at why.

Is it bad to roof in the rain?

Roofing in the rain is generally not recommended, as it can compromise the quality of the work and even pose a safety risk to the workers. Rain can make the roof slippery and increase the likelihood of slips and falls.

In addition, rain can cause materials to become wet and become harder to work with or adhere properly, potentially leading to leaks and other problems down the line.

If it is absolutely necessary to perform roofing work in the rain, precautions should be taken to ensure safety, and the quality of the work should be closely monitored.

What are the risks of roofed buildings in the rain?

  • Felt and shingles not adhering properly: Rain can make the roof slippery, and materials may not adhere properly, leading to leaks and other problems down the line.
  • Moisture penetrating under the underlayment: Rain can penetrate under the underlayment and damage the roof structure, causing potential mold, mildew, and rot issues.
  • Ruins the integrity of the roof: Roofing in the rain can compromise the structural integrity of the roof and shorten its lifespan, leading to costly repairs or replacements.
  • It’s hazardous: Roofing in the rain can be hazardous to workers, increasing the likelihood of slips, falls, and other accidents.
  • It can void your insurance claims: If roofing in the rain leads to damage or problems with your roof, insurance claims may be voided if it is discovered that work was performed in hazardous conditions.
  • It can void the warranty on your materials: Roofing in the rain may also void warranties on materials, leaving you responsible for any issues that arise.
  • Lightning: Roofing in the rain during a thunderstorm can also pose a risk of lightning strikes, which can be dangerous to workers and cause additional damage to the roof.

What should you consider when planning to install a roof in the rain?

Installing a roof in the rain is generally not recommended. However, if it’s an emergency and you must do it, here are some tips that can make it easier:

  • Safety first: The most important thing to consider when planning to install a roof in the rain is safety. The roof will be slippery and wet, increasing the risk of slips and falls. Make sure you and your team have proper gear like non-slip shoes, a harness, and a sturdy ladder.
  • Use proper tools: Roofing in the rain requires specialized tools like a roofing nailer with a coil roofing nail gun. This will make the job quicker and more efficient.
  • Work in sections: Plan to work on small sections of the roof at a time. This way, you can focus on one area and avoid getting the rest of the roof too wet.
  • Protect the interior: If possible, try to cover the interior of your house with tarps or plastic sheets to protect against water damage.
  • Use extra nails: When roofing in the rain, it’s essential to use extra nails to ensure that shingles, underlayment, and other materials are secured in place. This will prevent them from being blown away by strong winds or shifting due to water.
  • Have backup plans: Have a plan in place in case the weather gets worse. If the rain becomes too heavy, it may be best to stop working and wait for better weather conditions.
  • Call a professional: It is always best to have a professional roofing company handle your roofing project, especially if it needs to be done in the rain. They have the proper training, tools, and experience to do the job safely and effectively.

What kind of roofing shingles are best for roofing when it rains?

When it comes to roofing in the rain, it’s important to choose shingles that are designed to handle wet conditions and adhere properly. Some of the best roofing shingles for use in rainy climates include:

Asphalt shingles

These are the most popular type of shingles and are a great choice for rainy climates. They are affordable, durable, and can handle moisture well.

Rubber shingles

Rubber shingles are a good choice for places where it rains a lot because they are flexible and can handle harsh weather. They are also environmentally friendly and can last up to 50 years.

Slate shingles

These are a premium option that can handle wet conditions well. They are made from natural stone and have a beautiful appearance that can enhance the curb appeal of your home.

Metal shingles

Metal shingles are durable and can handle heavy rain and winds. They are also resistant to fire and can last up to 50 years with proper maintenance.

Clay tiles

Clay tiles are a popular choice in many parts of the world due to their ability to handle extreme weather conditions, including heavy rain. They are durable, long-lasting, and can add a unique look to your home.

What type of roofing underlayment is best for roofing in the rain?

Here are some of the best types of roofing underlayment for use in rainy climates:

Synthetic underlayment

This type of underlayment is made from a high-tech polymer material that is designed to resist moisture and provide an effective barrier against water infiltration. It is lightweight, easy to install, and can last up to 50 years.

Rubberized asphalt underlayment

This type of underlayment is made from asphalt that has been blended with synthetic rubber. It is highly waterproof and can provide excellent protection against water infiltration. It is also durable and can last up to 20 years.

Felt underlayment

Felt underlayment is a traditional type of underlayment that is made from organic materials such as wood or paper. While it is not as durable as synthetic or rubberized underlayment, it is still an effective choice for use in rainy climates.

Ice and water shield underlayment

This type of underlayment is designed to provide added protection in areas where ice and snow are a concern. It is made of rubberized asphalt that can seal around roofing nails and other holes to keep water out.

What should roofers do to prevent leaks when roofing in the rain?

Tarping a roof is an important step that roofers can take to prevent leaks when roofing in the rain. Here are some tips on how to properly tarp a roof:

  1. Choose the right size tarp: When selecting a tarp, it’s important to choose one that is large enough to cover the entire roof. The tarp should be long enough to extend several feet past the edge of the roof on all sides.
  2. Secure the tarp to the roof: Once the tarp is in place, it should be secured to the roof using roofing nails or screws. The tarp should be attached at the corners and along the edges, making sure that it is taut and does not sag.
  3. Overlap the tarps: If multiple tarps are needed to cover the entire roof, they should be overlapped by several feet to ensure that there are no gaps where water can seep in.
  4. Protect the edges: It’s important to protect the edges of the tarp by folding them over and securing them with roofing nails or screws. This will help to prevent the tarp from flapping in the wind and will also prevent water from seeping in around the edges.
  5. Remove the tarp as soon as possible: Once the rain has stopped and the roof is ready to be worked on, the tarp should be removed as soon as possible. Leaving a tarp in place for too long can cause moisture to become trapped underneath, which can lead to mold and mildew growth.

It’s important to know that a properly installed tarp can provide protection for up to 90 days. This can be helpful if roofing work has to be put off because of bad weather.

However, it’s important to note that the tarp should be checked regularly and replaced if it becomes damaged or starts to sag, as this can allow water to seep in and cause damage to the roof.

What kind of tarp should be used for roofing in the rain?

Vinyl-coated polyester tarps are a popular choice for roofing projects that involve tarping a roof in the rain. These tarps are made from a high-strength polyester fabric that is coated with vinyl to provide excellent water resistance and durability.

Vinyl-coated polyester tarps are made to last in bad weather, like rain, wind, and snow. They are also resistant to UV rays and other things in the environment that can damage the tarp. They also have reinforced corners and hems to keep them from ripping or fraying, which is especially important when tarping a roof in the rain.

When shopping for a tarp to use for roofing in the rain, it’s important to look for a high-quality product that is specifically designed for this purpose. Vinyl-coated polyester tarps are a great option to consider due to their strength, durability, and water resistance, but it’s important to choose a size and weight that are appropriate for the size and slope of the roof being covered.

How can roofers protect themselves when roofing in the rain?

Roofing in the rain is dangerous for workers, so roofers need to take steps to protect themselves and reduce the chance of getting hurt or hurting someone else.

To stay safe when roofing in the rain, roofers should wear appropriate clothing and footwear that is waterproof and slip-resistant to avoid falls.

They should also wear proper safety equipment, including harnesses and lanyards, at all times when working on a roof, even in wet weather conditions.

Roofers should be aware of the risk of lightning in the area and take appropriate precautions and seek shelter until the storm has passed.

They should also work to keep the roof and work area as dry as possible by using tools such as squeegees and buckets to remove standing water.

It is also important for roofers to take regular breaks to rest, rehydrate, and warm up if necessary since working in wet weather conditions can be physically demanding.

Working with a partner is highly recommended when roofing in the rain. Having a partner on the roof can help ensure that both workers are safe and able to assist each other in case of an accident or emergency.

Ultimately, prioritizing safety when working in the rain is crucial for roofers.

Working with a professional roofing company that puts safety first can help make sure the job is done well and safely, even when it’s raining.

What should I do if it starts to rain during roof installation?

If it starts to rain during roof installation, it can pose several risks to the process. Rain can damage the underlayment and make it hard for the shingles to stick properly, which can cause leaks and damage to the roof. Rain can also damage the exposed decking or insulation, leading to costly repairs.

In some cases, the rain may be light enough that it can be worked around, and the roofing contractor can continue with the installation without any issues. However, if the rain becomes heavier, it may be necessary to stop work and cover the roof with a tarp until the weather clears up.

Tarping the roof can help prevent water from penetrating the underlayment and damaging the roof, but it should be done carefully and correctly to avoid any accidents. It’s also important to make sure the tarp is properly attached to the roof so it doesn’t get blown away or cause any other safety problems.

How to determine when it’s raining too much to do your roof

When it’s too rainy to do your roof, the intensity and duration of the rain, the condition of the roof, and the type of roofing materials used all play a role.

In general, if it’s raining heavily or consistently for an extended period of time, it’s probably best to hold off on any roofing work until the weather clears up.

Here are some signs that it may be too rainy to clean your roof:

  • Heavy downpours: If there is a heavy downpour, with rain coming down in sheets, it’s likely too wet to work on the roof. This amount of rain can make the roof slippery, making it difficult and unsafe to work on.
  • Strong winds: Strong winds can make it difficult to work on the roof, especially if the wind is blowing rain into the workers’ faces, making it difficult to see and work safely.
  • Extended periods of rain: If it has been raining for several days or if there is a prolonged rain event forecasted, it may be best to hold off on any roofing work until the weather clears up.
  • Saturation of the roof: If the roof is already wet and saturated, and more rain is on the way, it may be best to wait until the roof has a chance to dry out before resuming work.

Can you roof over wet plywood?

It’s not a good idea to put a new roof over wet plywood because it can cause a lot of problems that can hurt the roof’s strength.

Wet plywood can become weak or rot, which can affect how well the new roof works and how long it lasts.

Moisture that gets stuck between the layers of the roof can also cause mold to grow, and the underlayment may not stick well to a surface that is wet.

If it’s still raining, we recommend placing a waterproof tarp over the exposed area and waiting for the rain to end.

Before putting on a new roof, it is best to wait until the plywood is completely dry. This will give you the best results.

How long does it take for a roof to dry after rain?

The time it takes for a roof to dry after raining can vary depending on a number of factors, including the severity of the rain, the type of roofing material, and the weather conditions following the rain.

In general, it can take anywhere from 8 to 24 hours for a roof to dry completely after a rain. If you live in a cool or humid area, it might take longer.

If the rain is light or brief, the roof may dry relatively quickly, particularly if the weather is warm and sunny afterward. On the other hand, if the rain is heavy or prolonged, the roof may take longer to dry, particularly if the weather is overcast or cool.

It’s important to note that even if the roof appears to be dry on the surface, there may still be moisture trapped between the layers of the roofing materials, particularly if the rain was heavy.

It’s best to wait at least a day or two after it rains to check on or work on a roof to make sure it’s completely dry and won’t get damaged or grow mold.

Is it OK if it rains on the underlayment?

Even though it’s usually not a good idea to leave underlayment out in the rain, most roofing underlayment is made to be water-resistant and can handle some moisture.

But if it rains for a long time, the underlayment can get wet and get damaged, which can make the roof less stable.

We strongly suggest using synthetic underlayment because it is designed to keep water away, so it is mostly waterproof. If you’re using felt underlayment, it will tend to absorb the water and may become damaged over time.

If either underlayment is only exposed to rain for a short time and is properly installed, it should be able to handle the moisture without getting too damaged.

But if it rains hard or for a long time, or if the underlayment is already damaged or weak, it might not be able to protect the roof deck as well as it should. This could lead to leaks and other problems in the future.

Can you install wet shingles?

It’s not a good idea to put on wet shingles because they can be harder to work with and may not stick properly, which could hurt the roof.

Wet shingles can also be heavier and more slippery, which can make it more likely that someone will get hurt or hurt themselves while installing them.

But if it rains hard or for a long time, or if the underlayment is already damaged or weak, it might not be able to protect the roof deck as well as it should. This could lead to leaks and other problems in the future.

To make sure that the shingles stick well and protect the roof well, it’s best to wait until they’re dry before putting them on.

What happens when you need a roof replacement in the middle of the wet season?

If you need a roof replacement in the middle of the wet season, it’s important to take certain precautions to ensure that the job is done effectively and safely, despite the challenges of wet weather conditions. Here are a few tips to keep in mind:

  1. Hire a professional roofing contractor: It’s important to work with an experienced and reputable roofing contractor who has experience working in wet weather conditions. A professional roofer will have the necessary tools, equipment, and expertise to install a new roof effectively, even in the rain.
  2. Choose the right materials: When replacing your roof in the wet season, it’s important to choose materials that are designed to withstand wet weather conditions. For example, you may want to consider a metal or rubber roof, which are highly resistant to moisture and can provide long-lasting protection for your home.
  3. Plan ahead: When scheduling your roof replacement, it’s important to plan ahead to avoid working during periods of heavy rain or storms. It’s also a good idea to have a backup plan in place in case the weather takes a turn for the worse during the installation process.
  4. Use tarps to protect the roof: If it starts raining during the installation process, it’s important to cover the roof with tarps to prevent further moisture exposure. This can help protect the roof from damage and ensure that the job is completed effectively.
  5. Ensure proper ventilation: Proper roof ventilation is important to prevent moisture buildup and ensure that the roof dries out effectively after the installation is complete. Be sure to discuss ventilation options with your roofing contractor and ensure that proper ventilation is installed.
