One of the most overlooked aspects of home building or renovation is the weight of the roof. More often than not, homeowners focus too much on the design and the material used, that they forget how its weight can affect structural integrity in the long run. Talk to your local Charleston roofers, and they’ll tell you one thing is for sure: weight matters.
Here are some circumstances proving that roof weight really matters. Note that there is an ideal weight for each material and the type of structure it’s going to cover.
Variations in weather should always be a major consideration when evaluating the structural integrity of your roof. For instance, high and great winds during hurricanes can press lighter roofs inward, causing them to collapse. In some cases, these winds may lift the roof off its foundations and cause damages or harm to other properties or people. Damages can be even worse if the casted off roof is heavy.
Perhaps the most common problem with light roofs is their ineffectiveness against heavy snowfall. Here’s what experts say about it that will make you rethink your roof weight:
“Snow has a great deal of weight, and that weight increases immensely when rain, ice and sleet are added to the mix. Two feet of snow on the average-sized roof can be the equivalent of 38,000 pounds, or 19 tons, NBC News reports. All of this weight puts stress on your roof and weakens its structure.
Complicating matters more, the melting of this mass can cause water seepage, which can rot roofs, destroy insulation, flood attics, ruin gutters and damage the interior of your home.”
Heavier roofs can cause more damage during accidents or natural disasters such as fires and earthquakes. When the ground shakes, expect that heavier shingles or slates will slide off their surface and destroy things they will fall onto. During fires, collapsed roofs may trap people inside.
Roofs have something to do with the efficiency of your home. Ultra-thin roofing allows heat to pass through easily and bypasses insulation. This heat may get into appliances and cause them to work more. You may also observe a similar effect if you use heavy roofs, which usually retain heat for longer periods.
The weight of the roof matters. Consider roof weight in conjunction with other factors such as the materials used, the weather, and overall home structure. More importantly, seek the advice of reliable roofers in Charleston SC like CMS Roofing.
