Can You Put Shingles On A Wet Roof?

Can You Put Shingles On A Wet Roof?

Houses have long been used as a primary means of sheltering us from the different forces of nature. Whether we’re protecting ourselves from rain, snow, scorching heat, or even hailstorms, we owe it all to our roofs for keeping us safe and away from the elements of the weather. However, not all roofs last forever, and sooner or later these roofs will eventually give in to age and damage. 

One of the most prevalent forms of damage is from water when it seeps inside the interiors and supporting structures of your roof. In almost every regard, contractors would highly suggest NOT to reroof and install shingles on a wet and moist roof since this can lead to a variety of different problems and damages. If you’re not sure about the process and if you need a roof replacement on your home during some of the wet months of Sugarland TX, then it’s best to acquire the services of a professional roofing contractor.  

Reroofing Under The Rain 

Reroofing and the installation of new roofs can be a big investment; it will take a considerable amount of time, effort, and money. With that said, it’s best not to squander these resources by making sure that you’re reroofing under the right conditions. 

Before we get into the process, we have to first have a checklist of the right conditions to take into account.

The Weather Should Be Sunny

It’s best to install your shingles under sunny weather when the temperature is warmest. One of the reasons why shingles bulge and warp is when these are installed in colder conditions. In most cases, roofing materials that are made out of certain materials will expand when exposed to higher temperatures and shrink in colder weather.

Additionally, having a good amount of sunlight can help evaporate water that might have been left on your roof. 

Your Roof Should Be Dry

Your roof should always be dry whenever you are reroofing. Having a dry roof can mitigate any damages that might be caused by fungal and organic growths. Moreover, water and moisture won’t be trapped inside the roof’s interiors. 

Check For Warped And Bulging Shingles 

Obviously, having warped and bulged shingles can also damage other shingles in the process while disrupting the flow of water that would have been discarded properly. Having a professional roofer can help inspect your roof for any damages so that any broken shingles can be replaced in no time. 

Why You Shouldn’t Reroof Under The Rain 

Hazardous To Workers

Roofing specialists and contractors shouldn’t be working in such hazardous conditions. If you’re working on your roof while it’s raining, your shingles will get slippery and there will be a possibility that workers will be injured. Aside from limited visibility, especially during heavy rain, the roof slope, wet and slippery surface, and the oncoming rain will heighten the chances of someone slipping and falling.

Shingles Can Slip Off

Installing roofing shingles on top of a wet roof can make your new roofing materials slip off and become damaged. Certain interior parts like barriers, OBS boards and felts are also quite sensitive to water. 

May Void Warranties 

The manufacturers of roofing materials can ensure that their products are durable, but we also have to take into account the installation of the materials. Warranties have specific guidelines that have to be followed to retain the efficacy of such warranties. Manufacturers are not held liable for specific forms of damages. 


To conclude, it’s best to perform roof replacement when it’s not raining and when your roof is dry. Reroofing, while it’s raining, can spell disaster for the integrity of your roof as moisture is trapped on your roof’s interior which can result in the formation of mold and mildew. To avoid this, it’s best to thoroughly inspect your roof first while making sure everything is dry.

In terms of weather, it’s highly recommended to place shingles on your roofing Sugarland TX during sunny weather when the temperature is high. Roofing materials, like metal and copper shingles, tend to expand when exposed to higher temperatures so it’s easier to get an accurate representation of what your shingles will look like when you’re installing your roof. 

Ultimately, roof shingles are installed to keep flowing water and moisture off the roof and away from our home’s interiors. It is quite counter-intuitive to be reroofing while it’s raining since water and moisture will flow towards your roof’s interiors. Again, having professional supervision and expertise can help mitigate any water-based damages to your roof.
