One of the roofing pros we spoke with says mist won t affect osb any more than the humidity that osb absorbs on a hot day.
Roofing in the rain ok.
It is not the fault of your contractor and while the delays can certainly be frustrating a contractor who attempts to install a new roof in the rain is going to be compromising the overall integrity of the installation.
Safety is always a primary consideration for roofers and roofing in the rain requires caution.
If it starts to rain or drizzle the roofers should act quickly to cover your osb most likely with a tarp.
Summer sun and high heat make working in a little rain a viable option.
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.
Roofing in the rain not only means you or your roofing experts will be extremely wet uncomfortable and exposed to more risk but it also means that your new roof could have less integrity than if it were installed in dry conditions.
Be wary of a roofing contractor who promises to install a new roof regardless of the weather.
Shingles will not stick to a wet roof.
