Having a new roof installed is an expensive and time consuming process—one that requires months of planning. Yet sometimes a damaged roof simply can't wait. If you have a roof in need of some temporary repairs, read on. This article will teach you how to address two common shingle problems.
Curling is a common sign of asphalt shingles that have begun to get on in years. Likewise, this condition may be caused by incorrect installation or certain environmental circumstances—primarily for those who live in areas that swing rapidly between states of high and low humidity. Finally, this issue can be caused by a failure to install underlayment below the shingles; a lapse that makes both the shingles and the decking especially vulnerable to moisture issues.
When this issue begins to affect your shingles, it is generally a sign that it's time for a new roof. Yet in the short term the problem can be mitigated through the use of roofing sealant. Applied to the underside of the curling shingle with a caulk gun, this sealant essentially glues the shingle down, thus preventing it from curling upward once again. Be sure to weight the shingle down using a brick to ensure a firm bond between the glue and the underlying shingle.
It is also a good idea to take some time to address any issues that may be contributing to your curling shingle problem. Ensuring that your roof is adequately ventilated is one key thing. That's because poor ventilation leads to the formation of ice dams in winter; when warm weather rolls around and these ice dams start to melt, the sodden shingles are much more likely to experience unwanted curling.
Just as with curling, cracked shingles are generally a sign that your roof is getting on in years. However, even relatively new shingles can crack when subject to extreme weather conditions such as high speed winds and sub-zero temperatures. The good news here is that if the problem isn't too widespread, it may be possible to correct it fairly easily.
Once again, the solution involves the application of roofing sealant. First, the sealant is applied to the underside of the crack, and then the shingle is pressed down firmly atop it, and another layer of sealant is applied on top. This fix works equally well for torn shingles. Just be sure that the damage isn't so severe that it is exposing the underlying roof decking. If it is, you will be better off replacing the shingle with a new one.
