A sagging region in the roof can be an issue. Although a slight sagging does not necessarily mean that your roof is at risk of falling down, it can suggest that you should take action quickly to protect the structure. Most times, a roof that’s sagging can be fixed and strengthened. To ensure the roof’s integrity it is recommended to hire an expert to find out what is the reason for the sagging, and then take action to rectify it.
A Water-damaged Water-Resistant Roof Surface
Snow and rain can swiftly cause damage to a roof that’s not properly designed and maintained. Shingles, as well as other roofing materials should be in good working order to let water flow away. Metal flashing must be put in place in the valleys and junctions of your roof to help direct water away. Any damage to the roof’s surface provides water the opportunity to seep into the roof and weaken the structure.
A damaged or poorly-designed gutter system could result in water issues. If the water runoff isn’t properly removed through drains or gutters it could build up on the roof and then seep into the roof.
Insufficient airflow in attics can cause the water issues. If there isn’t enough airflow in the atticarea, moisture accumulates on the roof’s underside which makes it easier for water to seep into your roof’s surface. This also causes the summer heat to increase which accelerates the degrading of your shingles.
If water damage causes your roof to buckle The first step would be to fix the issues that caused the damage to happen. This could mean replacing the flashing and shingles and gutters, or repairing them, and enhancing the ventilation in your attic.
To fix the sagging the angled braces could be put in place to reinforce the rafters. Another method is to add greater support to walls by putting chains on to wall plates, and connected in the middle by turning buckle. Based on the extent of sagging, your contractor could need to install posts for jacks in order to elevate the roofing prior to construction of any strengthening.
Extra weight from Snow along with Design Flaws
Each roof is built to support a particular maximum weight , and anything over this, particularly for prolonged durations, could cause the roof to slide. In cold winter conditions snow is the main reason for excess weight being placed on the roof.
If you believe that the snowfall is causing your roof to slide in order to ensure your security and to ensure the safety of your roof, think about getting a professional in to clean your roof of the heavy snow. Improper snow removal could cause damage to your roof which makes it more vulnerable to water damage and exacerbated sliding. A roof rake can assist to deal with snow that is lighter. Make sure that your attic is properly insulated and ventilated to stop the formation of ice dams that could lead to roof leaks.
Sagging caused by weight is also caused due to design flaws which render the roof unsupported by the weight of its own. The most frequent flaws are the insufficient size of rafters, inadequate sheathing, or too many collar or rafter tie-ups.
When you’re dealing with a stick frame (non-truss) steeply sloped roof these issues typically result in the roof ridge to be sagging in the middle, which gives the appearance of swayback and can cause the roof’s side to slide. Installing new rafters directly on the damaged or weak ones will often be enough to fix this issue.
If the roof is sagging between the trusses or rafters The most likely reason is that the sheathing is too thin for the space it covers. The solution would be to substitute the sheathing by thicker sturdy sheathing.
Multiple layers of shingles as well as new roofing material that is heavier than the roofing material it was intended to support can lead to sliding even on a well-constructed roof.
In the event that your roof appears to be wobbling because of the pressure from too many roofing shingles it is recommended that all shingles must be removed followed by a brand new one put in. This gives the roofer an opportunity to examine the roofing underlayment and the flashing to determine if there is damage. If your roof began to slide when you changed to a heavier roofing materials like replacing wooden shingles with clay tiles or clay tiles, you’ll likely have to switch back to the light material.

Issues with the roof isn’t the only reason that a roof can slide. If your foundation has moved or sinks or sunk, the roof and walls could have also shifted with it. If this is the case you’ll likely notice a tilt or cracks appearing in the foundation. To fix major damage to your foundation you’ll have to consult with a professional in construction.
