What Can Cause a Roof to Sag?

Sagging is one of the most visible problems any roofing system can have. If you see any sign of sagging or physical deformation on your roof, call your local roofing repair contractors right away. When left unchecked, sagging can cause serious issues on the structure of your home and can even lead to total roofing failure.

Sometimes, all it takes to nip sagging problems in the bud is recognizing its early symptoms. To do this, it helps to know what can cause sagging in the first place. 

Ice and Snow

Issue with ice and snow most often occur during winter, but they are still worth mentioning. Heavy snowfall can add a lot of weight to your roofing system. When it melts, it could also lead to the formation of dangerous ice dams. You can avoid ice dams by cleaning your gutters before the season starts. If possible, enlist the help of your local contractors to clear away excess snow on your roof during days of heavy snowfall.

Water Penetration

For the rest of the year, liquid water is the number one enemy. Water penetration problems can be caused by missing shingles or even excessive humidity levels inside your home. Water can soften the wooden beams and rafters that hold the roof deck in place, which may cause it to sag. Replace faulty flashing and ventilate your attic to minimize moisture from inside the roofing system.

Old Age

Wear and tear can also cause sagging problems, especially in aging roofing systems. Regular maintenance can help stave off the effects of aging and extend the life of your roof, but eventually, the time will come when you will need to replace the whole roof entirely.
