When preparing for a roof renovation, you have control over many factors, including your contractor selection, preferred materials, project timeline, and budget. But one element that remains outside our control is the weather. Rain can hamper any home improvement project but can greatly impact a roof repair or replacement. After weeks of planning, you may feel impatient or frustrated when a storm lingers. Learn more about how rain may impact your project.
Can You Replace a Roof in the Rain? Not Without Risk
While some roofing projects can be completed in as little as a day, the average home re-roof with take several days. It is best to wait until conditions are clear, and your roof is dry, to make any repairs and installations. A slick roof can put workers at risk, and increases the likelihood for injuries and damage to your home.
This is also an important note for homeowners considering DIY roof repairs. Professional contractors will recommend waiting until conditions are clear before exploring a rooftop, even if just surveying the scene.
Shingles May Not Properly Adhere to Wet Surfaces
A wet installation can also cause a new roof to fail. Shingles and roofing materials may not adhere properly to slick surfaces with high humidity. If the sheathing or wood is wet during the time of installation, it can trap moisture inside of your roof, leading to mold, rot, or other severe problems.
Many of the inner components of your roof—such as barriers, OSB boards, and felt— are also sensitive to water damage and should not be exposed to moisture. In high humidity, materials may bulge or wrinkle, causing ripples and bumps on the exterior surface of your roof. In addition to being unappealing, wrinkling can also signal problems down the line. Roofing professionals agree that a rippling roof is a sign that a home needs to be reroofed as soon as possible.
Installing a Roof in the Rain May Void Your Warranty
Roofing manufacturers guarantee their products, but not the installation. Specific guidelines are set for how shingles and materials should be installed, so the manufacturer is not liable for damage that results from faulty workmanship.
If a roofing installer decides to work under less-than-ideal weather conditions, it could lead to your manufacturer voiding their warranty, resulting in costly repairs down the line.
If Undergoing Emergency Repairs, Be Cautious When Hiring a Roofing Contractor
There are instances where a temporary fix or repair on a rainy day is unavoidable. An emergency repair, such as a leak and roof water damage, may need to be addressed or completed as soon as possible. If your home suffers catastrophic damage, like an impact or collapse, an emergency roofer may need to make temporary fixes to protect your home from further damage.
During this stressful time, it is paramount to research the installer assisting you with this emergency. Many times, when a storm comes through an area, it draws disreputable contractors who are looking to scam unsuspecting, alarmed homeowners.
An unreliable contractor may tell you that it’s okay to install shingles on a wet surface, just so they can haphazardly “complete” the job and move on to the next home.

Wait Until the Weather is Clear
When installed properly, your new roof will last you ten years or more. It is best to avoid rainy day installations. Delaying a repair a few days for foul weather to pass is well worth the wait.
If your roofing contractor suspects a storm is approaching, expect a call postponing the project until the weather has passed.
