Can You Do Roof Work in the Rain?
You fielded estimates, worked with your contractor to select shingles that work for your home’s style and your budget, you even cleared off your driveway so crews could get to your roof easily. Then it rains – and puts a damper on your roofing project.
While mild sprinkles aren’t a major factor in completing your roofing job, real rainstorms do put a damper on roof repair work for a variety of reasons. First off, it’s a safety issue: We shingles are more slippery than dry ones, and B&M Roofing of Colorado treats worker safety of utmost importance. We’re not going to risk our workers on rainy rooftops.
Even if it was safe enough to work in the rain, there are a lot of reasons why adding a roof in a rainstorm is a terrible idea, mostly because your roof’s primary function is to protect the rest of your home from moisture. When shingles or sheathing is placed over a wet roof deck, moisture is trapped beneath your roofing and can’t evaporate. Moisture trapped beneath shingles can lead to mold or rot that will go undetected until problems arise.
In worst-case scenarios, roof decks can absorb large amounts of water trapped below roofing materials, as water seeps into the wood of the roof deck, causing it to swell with the extra moisture. This process, known as buckling, leads to uneven roof decks, poorly fitting roofs and may create spots on a roof that don’t drain correctly.
We keep a close eye on forecasts and, in some cases, may reschedule appointments with homeowners in order to leave old roofs intact until storms blow through. Colorado summers are notorious for storms, however, and we also provide crews with tarps to shield exposed roof decks from rain. In many cases, we can remove these tarps and get back to work shortly afterward.
