What Happens If It Rains While Installing a New Roof?

Installing a new roof is a major home improvement project, and timing plays a crucial role in ensuring a successful installation. But what happens if it starts raining while your new roof is being installed?

Rain during a roof installation can be costly, unsafe, and can affect the quality of your new roof. In this blog, we’ll discuss why installing a roof in the rain is a bad idea, what to do if unexpected rain occurs during installation, and how professional roofers prepare for unpredictable weather.

Installing a New Roof in the Rain Can Be Very Costly

Why Rain is a Problem for Roof Installation

Rain and moisture are enemies of proper roof installation. Roofing materials, especially underlayment and wood decking, must remain dry for a secure and durable installation. If rain soaks into these materials, it can lead to:

✔️ Weakened roofing materials that don’t provide proper protection
✔️ Water damage to the roof structure before the installation is complete
✔️ Mold and mildew growth from trapped moisture
✔️ Delays in installation, increasing labor costs

If a roofing contractor proceeds with installation in the rain, your new roof could fail prematurely, resulting in expensive repairs or even a full replacement much sooner than expected.

Your Roof Won’t Be Installed Correctly If It’s Raining

A high-quality roof installation requires a dry and stable surface. Rain can interfere with proper shingle adhesion, cause nails to slip, and even prevent roofing cement or sealants from setting correctly.

How Rain Affects Roof Installation

🔴 Underlayment Damage: Roofing underlayment is designed to act as a water-resistant barrier, but it should be installed dry. If it gets wet before shingles are installed, it may wrinkle, tear, or lose its effectiveness.

🔴 Decking Issues: If moisture seeps into your roof decking, it can cause swelling, rot, and structural weaknesses, leading to serious long-term issues.

🔴 Compromised Shingle Sealing: Asphalt shingles need time to bond properly. If installed on a wet surface, they may not seal correctly, leading to leaks and premature deterioration.

🔴 Flashing and Sealant Problems: Flashing and other roofing materials rely on dry conditions for proper adhesion. Rain can wash away sealants before they set, leaving your roof vulnerable to leaks.

Bottom Line: If your roofing contractor installs your roof in the rain, it’s not going to be done correctly—and that can lead to major issues down the road.

It’s Not Safe to Install a New Roof in the Rain

Safety Hazards for Roofers

Roofing in the rain doesn’t just put your home at risk—it also creates dangerous working conditions for roofers.

🛑 Slippery Surfaces: Wet shingles and underlayment can become slippery, increasing the risk of falls.

🛑 Electrical Hazards: Roofing contractors use power tools and equipment that can be hazardous when exposed to water.

🛑 Poor Visibility: Rain can impair visibility, making it harder for workers to maneuver safely on the roof.

A responsible roofing company will never install a roof in the rain due to these safety concerns. If rain is in the forecast, your contractor should reschedule the project to ensure both safety and quality installation.

What Happens If It Starts Raining While Installing Your New Roof?

Even with careful planning, the weather can be unpredictable. If rain starts midway through your roof installation, here’s what should happen:

1. Work Stops Immediately

A professional roofing company will pause the installation process as soon as rain begins to avoid water damage to exposed materials.

2. The Roof is Covered with Tarps

To prevent moisture from penetrating the roofing system, roofers will use heavy-duty tarps or waterproof coverings to protect:

✔️ Exposed decking
✔️ Partially installed underlayment
✔️ Unfinished sections of the roof

3. Roofing Materials Are Stored Properly

Shingles, underlayment, and other materials should be kept dry to avoid warping or damage. A reputable roofer will store materials in a dry, covered area to ensure they remain in good condition.

4. The Installation Resumes Only When Conditions Improve

Once the rain stops and the roof is completely dry, roofers will inspect all affected areas and proceed with installation only when it’s safe.

How Should a Roofer Prepare for Rain During the Roof Replacement Process?

A professional roofing company will take precautionary steps to avoid rain-related problems before starting a roof replacement.

Key Steps a Roofer Should Take:

✔️ Check the Weather Forecast: Reliable roofing companies closely monitor weather conditions before scheduling an installation.

✔️ Use Proper Scheduling Techniques: If there’s even a small chance of rain, they should have a contingency plan in place.

✔️ Have Tarps and Waterproof Covers Ready: A prepared roofer always keeps waterproof tarps on hand to cover your roof if rain starts unexpectedly.

✔️ Plan for Drainage: Before installing a new roof, professionals will ensure proper water drainage to prevent pooling or leaks.

✔️ Communicate with Homeowners: If the forecast looks risky, your contractor should reschedule the installation rather than risk a faulty roof.

A reliable roofing contractor will never rush the job if conditions aren’t right. They’ll always prioritize quality, safety, and long-term durability over speed.
