Contrary to popular opinion, sagging roofs are a common occurrence and one of the main reasons people want to replace their roofs. While there are many reasons for this event, most roofing companies can condense it to three primary causes.

Age

One of the most obvious reasons is age. Wear and tear may take its toll on your roof over the years, especially if it’s more than 20 years old for asphalt roofs and more than 30 for others. In this case, sagging isn’t a problem per se, but a warning that you should replace your roof right away, or you’ll be facing a total roof collapse soon.

Weather Damage

The roof is your shield against the elements, and, as a consequence, it naturally encounters a lot of moisture on a daily basis – even without rain! Humidity, especially on hot, muggy days, can gradually decrease the effectiveness of your roof. Storm damage, meanwhile, can erode the structural supports of the roof deck, causing the roof to sag or bow inward.

If you know that your roof is sagging after a particularly nasty weather event, waste no time, and call us so we can provide immediate solutions.

Extra Weight

A roof is heavy enough as it is, which is why many contractors need to calculate precisely how much weight the walls and your foundation can support. But while these components are built to take weight, your roof doesn’t. If your roof is a typical asphalt shingle construction, adding accessories may not always be a good idea. In addition, packed snow during winter can be hefty as well, so clearing or raking it should be one of your priorities.
