Old roof needing to be fixed with rain running off

In short, no, a roof should never be replaced in the rain. While it may be tempting to fix a leaky roof as soon as possible, attempting to replace a roof in the rain can lead to many problems that can cost you more time, money, and headaches in the long run.

In this article, we’ll discuss the various issues that can occur when installing a roof in the rain and how roofing contractors handle rainy weather during a roof replacement.

What Happens if It Rains While Getting a Roof Installed?

Most roofing contractors will closely monitor the weather forecast before beginning any roofing work. If there is a chance of rain in the short-range forecast, they may postpone the job until the weather improves. This may extend how long the roofing project takes but is worth the additional time required. 

Should it start raining while the work is in progress, contractors will typically cover the roof with a waterproof tarp or material. Doing so will prevent any water damage to the home’s interior, thus safeguarding its inhabitants and protecting the structure from potential long-term deterioration.

Issues That Can Happen When Installing a Roof in the Rain

While there are many reasons why you shouldn’t replace a roof in the rain, here are a few of the most significant issues that can occur:

Shingles May Not Properly Adhere

One of the major problems with installing a roof in the rain is that the shingles may not adhere to the roof’s surface correctly. This can happen because the rainwater can make the roof’s surface wet, which will cause the adhesive to lose its bonding properties. As a result, the shingles may not stick to the roof properly, which can lead to many problems down the line.

When the shingles don’t adhere to the roof, they can lift or shift, allowing water to seep underneath them and cause leaks or water damage in the home. In addition, if the shingles don’t adhere properly, they may be more prone to damage from wind, hail, and other weather conditions, reducing the lifespan of your shingle roof.

It’s worth noting that even if the shingles adhere to the roof, there’s still a risk of water damage if the roof isn’t properly sealed. When the rainwater hits the roof, it can seep through any gaps or holes and cause damage to the underlayment and decking underneath the shingles. The roof’s structure can be weakened as a result, making it more susceptible to storm damage in the future.

For any roofing work to be done correctly and properly protected from the elements, waiting until the weather clears up is essential.

Increased Risk to Workers

Another issue when installing a roof in the rain is an increased risk to workers. A wet, slick roof puts contractors at more risk of an accident, injuries, or damage to the home. The roof can become extremely slippery, making it difficult for workers to maintain balance. As a result, they may slip and fall, resulting in serious injuries.

Even if the workers can maintain their balance, the slick surface can make it challenging to maneuver heavy roofing materials around the roof safely. Accidental damage to the roof or property is more likely as a result. 

Moreover, if a worker slips or falls and damages the roof or other property, it can result in additional repair costs and delays in completing the project.

To mitigate these risks, roofing contractors will typically reschedule the project if there is rain in the forecast or if it begins raining during the project. They will ensure the work area is secured and tools and equipment are properly stored. In some cases, they may use safety harnesses or other safety equipment to minimize the risk of falls.

In addition to worker safety, installing a roof in the rain can pose a safety risk to anyone in the surrounding area. Falling debris or materials can cause damage or injury to people or property below. 

May Void Warranty

Installing a roof during rainy weather may void the manufacturer’s warranty. Most roofing manufacturers provide a warranty that covers their products against defects or premature failure, but they often include specific guidelines that must be followed during installation.

If the guidelines are not followed, the warranty may be voided. One of the most common requirements is installing the shingles on a dry surface. Installing shingles on a wet roof can prevent them from adhering correctly and can cause premature failure, which could result in the manufacturer denying any warranty claims.

Therefore, if you decide to install a new roof in rainy conditions, it’s essential to check the manufacturer’s warranty carefully. The warranty may explicitly state that the installation must occur during dry weather, which means that any damage or premature failure of the roofing system caused by the installation in the rain will not be covered by the manufacturer’s warranty.

In addition to voiding the warranty, installing a roof in the rain can also lead to other issues, such as mould growth or damage to the insulation or the decking beneath the roof. 

These problems can be expensive to repair and lead to additional long-term issues with the roofing system. Therefore, it’s best to be patient and wait for dry weather conditions before installing a new roof. This will ensure that the installation is completed correctly, safely and that the manufacturer’s warranty will remain valid.

Emergency Roof Repair in the Rain

When it comes to roofing emergencies during bad weather, such as a severe storm or hurricane, roofing contractors will take necessary precautions to prevent further damage. They may use tarps or other waterproof materials to temporarily cover the damaged area, protecting it until the weather clears up and permanent repairs can be made.

In case of an emergency roof repair during the rainy season, it’s best to call in a professional roofing contractor with experience in performing repairs in wet conditions. They will have the necessary equipment and safety gear to complete the repair safely and efficiently.

It’s essential to address any emergency roof repairs as soon as possible to prevent further damage to your home’s roof and interior.
