A sagging roof doesn’t just look unsightly; it may also be an indication of possible structural issues with your home. When you notice your roof developing an unusual curve, it is best to consult a professional roofing contractor, such as Empire Roofing & More. 
Even if you can reach out to an expert roofer, it is still a wise move to know what could possibly cause your roofing system to sag. Doing your homework will help you determine whether or not you’re getting the right service from your contractor. Here are three of the biggest culprits behind a sagging roof:
- Too much weight – Rafters and ceiling joists have the important task of supporting the weight of your roof. They may lose their strength over time, especially when the roof has to deal with heavy snow, moisture leaking into the frame, and movement caused by expansion and contraction from intense temperature fluctuations.
- Substandard materials – As with siding, the quality of roofing material you use will also determine whether your roof will perform at its best for a long time. For example, some materials may be more affordable than others, but they can wear out quicker than sturdier options like asphalt or slate. Nails, beams, framing structure and other elements should also be taken into consideration.
- Natural aging and elements – The age of your materials can also cause your roof to sag. They won’t last forever, but you can prolong the life of your roof by including roof inspections in your maintenance list. Consequently, different weather conditions can wreak havoc on your system as well. Trapped moisture in between shingles and the board may cause your roof to weaken and sag. Be sure to have a proactive maintenance plan in place to keep your system in top shape.
