A drooping roof is a problem that can cause leaks and water damage to the inside of your home. This can occur when the roof is not properly supported. Age, improper installation, or poor design could be to blame, but it could also be a combination of these three issues. You are in luck since there are a lot of things you can do to fix it on your own without having to shell out money to hire a professional roofing company.
This article will explain some of the most prevalent factors that lead to sagging roofs, as well as provide information on how such roofs can be repaired at home using basic materials such as shingles, tar paper, and plywood sheets. Everyone will be able to follow along with us because we will also provide detailed instructions on how to complete this task.
In what ways might sagging roofs be prevented?
Even if you've done everything in your power to keep your roof in excellent condition over the years, the effects of time and weather will eventually cause it to sag. If you live in an area that frequently experiences extreme weather, it's likely that your roof isn't really that old but is showing signs of wear and tear as a result.
Finding the root of the problem is essential for fixing your sagging roof. Some of the most important causes of your roof sagging are as follows:
Because of the added load, when was the last time you had your roof inspected? The sinking roof could be a sign of structural problems. When roofs are subjected to weight loads that exceed what they were meant to hold, sagging can occur. If your roof has inadequate storm bracing or your rafters are too narrow for the roof, snow and ice can cause the roof to sag.
Even though roofs are designed to efficiently drain water, prolonged flooding or heavy rainstorms can harm the roof's structure.
If you have a faulty gutter system or broken shingles that prevent water from escaping, the supporting structure could rot.
The sagging of a roof can be caused by a number of factors, including old age, poor quality materials, and a foundation that is cracked or sinking. These are more possibilities.
If your roof is drooping and you need help pinpointing the problem, please contact the Legacy Service team to schedule an appointment.
When extra weight is added, the roof is put under a tremendous amount of stress. The roof can be subjected to significant loads from a variety of sources, including snow, ice, and even wind. Without proper structural support, the roof will eventually sag under the weight of rain, snow, and other precipitation.
It's possible that water damage from rain or snow led to the sagging of the roof. The roof must be in good condition so that water may be properly channelled away from the shingles.
A leak can enter the home through any hole or crack in the roof, hastening the roof's degradation and eventual sag.
Extreme loads along the roof's surface may result from snowfall. In frigid climates, where snow might linger on the roof for months at a time, the building will finally collapse. That's very true.
There is a maximum load that each roof can safely bear before it begins to sag; any further weight will cause the roof to collapse.
Problems with the building's framework might also lead to the formation of roof valleys. It's the poor forethought and workmanlike execution during construction's building phase again. If any of the roof's supporting elements are compromised, the roof may sag.
Failure of the roof's supporting elements, such as the walls of the building, can also lead to the formation of roof valleys. An old roof is usually the cause of a sagging ceiling.
Low-quality roofing materials are quickly accelerated in their breakdown by exposure to the environment and water. On the downside, the typical lifespan of these roofs is only 15-30 years, depending on the local climate and the specific design.
The walls could have shifted if the foundation of the structure had shifted or sunk.
The emergence of cracks in the foundation is a direct result of these catastrophic shifts. When the structure's base and walls are altered, the roof will inevitably sag.
Examine The Level Of Damage
Once the source of the problem has been isolated, the following step is to assess the level of damage. Again, we'll discuss some do-it-yourself options shortly, but in most circumstances, we recommend getting expert help.
Keep in mind that if you ever need help with the outside of your property, you can always contact us here at Legacy Service. However, here are some steps you may take to assess the damage yourself from the outset:
If you travel around the house's back, you'll be able to see exactly where the sag would be if it were inside.
With the use of a flashlight, investigate the rafters and decking of your attic, paying special attention to the sagging spots on your roof. Next, inspect the metal or plywood gusset plates.
A Checklist of Necessary Roofing Equipment
Therefore, you have already determined the nature and scope of the problem. Now that you know what parts you'll need, you may begin repairing your sagging roof. We have compiled an inventory of what you will probably need to do the job. Here are a few examples:
- Flashlight
- Nuts, washers, and other fasteners
- Chisel\sDrill
- Instrument for measuring distances, commonly known as "tape"
- Nails and a nail gun
- Chrome-plated "L" channel steel
- Wooden struts
- Plywood
- Supportive Styrofoam Belt for the Lower Back
Once you have gathered all of the required materials, you can get started on the project itself.
Ahead of Time.
Fixing a sagging roof is no small task, so before you start working on it, make sure you have adequate roofing experience. Failure to do so increases the likelihood of a shoddy result.
Having your roof evaluated to determine the root of the problem and why it is sagging is the first step before taking any action. This crucial step will help you assess the damage and determine the associated material costs.
The sagging of your roof may be the consequence of trusses or rafters that have been damaged and need fixing. The extent of the damage is what will determine the cost of the repair.
If the roof's main support beams are gone, the cost could skyrocket, but if it's just a little section that requires fixing, it could be far less.
Guide to Repairing a Sloping Roof
- Check for sagging ridgelines, bowing, and dips by first taking a look at your home from the street, and then by walking all the way around it.
- If the house has an attic, take pictures of the sagging rafters or sagging trusses with a camera. Providing, of course, that there is an attic.
- Check for any signs of damage on the plywood or metal gusset plates.
Issues of Security
- You should take great care while venturing into your attic due of the darkness and the close quarters. Maybe you need to think about bringing in some more lamps.
- Roofs that have sagged should be repaired with caution, so always have the proper safety gear on hand. You should use protective gear including gloves, goggles, and a face mask with the right filters.
- Sagging roofs are dangerous because they can collapse at any time, causing serious injury or even death.
Determine the extent of the roof's damage through a thorough inspection.
You should start by making sure the roof isn't sagging. Looking up at the roof from the sidewalk is a good idea after that.
Thereafter, you need to inspect the roof from the inside of the house, so grab a flashlight and head up to the attic. From this vantage point, the full extent of the damage can be seen.
Roof trusses are the framework that supports the roof, so they need to be built with care. Check for issues like cracks, decay, and breaking to determine the item's condition. In most cases, a drooping roof may be traced back to faulty trusses or rafters that need fixing or replacement.
Holes Needed to Be Drilled Into A Steel "L" Channel.
It can be challenging to put a rafter or truss back in its original location after it has been damaged. This is a challenging part of the work.
Obtaining a steel "L" channel with at least 1.5 inch by 1.5 inch dimensions and a length of no less than two feet is the most efficient way to accomplish this goal. After that, make four 3/8-inch holes in the bottom of the steel "L" channel, and then another four in its sides. The hole spacing must be consistent.
Get rid of the wood's chips and splinters.
Next, you'll want to pick up any stray planks of wood that may have fallen from the truss or rafter. It is crucial that this step be accomplished successfully, as chips and splinters in the wood could potentially hinder the alignment of the rafter or truss. The presence of rubbish or splintered timber can be a contributing factor.
Connect one end of the "L" channel to the rafters.
Determine where the damaged section of the truss or rafter is, and then attach the "L" channel using the 3/8-by-2-inch lag bolts. After that, you'll need to drill holes into the side of the steel "L" channel to accommodate the carriage bolts and washers (typically 3/8 inches by 212 inches).
Check the distance between the rafter and the "L" channel.
The space between the "L" channel and the rafter or truss is the next dimension to be calculated. Again, a lag bolt with a diameter of three-eighths of an inch and a length of one and a half to two inches is advised to fill the gap between the "L" channel and the rafter or truss bottom.
Add Two Bolts At The Bottom Of The "L" Channel And Tighten Them Until The Rafter Is Secured.
After that, place two lag bolts at the bottom of the "L" channel, and then proceed to tighten them until they are flush with the steel.
It is advisable to tighten the bolt that is located the farthest away from the separation until the other bolt head is one quarter of an inch away from the steel.
After that, you can start to tighten the front bolt until it is a quarter of an inch away from the steel, and then continue this process until the rafter or truss is positioned such that it is in close proximity to the steel.
If more bolts are required, use them, and tighten everything up.
If more bolts are needed, you can simply bore two more holes at the same location on the "L" channel's side. Finally, after making sure the nuts, washers, and bolts are snug on the steel and giving everything a nice, firm twist, you may instal the carriage bolts.
Get in touch with a roofer immediately.
Hiring a roofing expert is a good idea if you are unsure of your abilities to fix a sagging roof on your own, or if you are having difficulty finishing the job on your own.
Sagging roof repairs can be dangerous and difficult to complete if you don't have experience with them.
In addition to ensuring a task well done, hiring a contractor will end up saving you time, effort, and money. Knowledgeable roofers also have an understanding of the tools and supplies that will be needed to finish the work successfully.
How To Fix Sagging Roof Trusses Or Rafters
When attempting to repair your roof, you will frequently find that it is necessary to fix drooping trusses or rafters. In the event that this is the case with your property, you should take the following measures to verify that the rafter or truss in question is correctly fixed:
- In order to restore the original form of your rafter or truss, you will want a steel "L" channel.
- Drill a hole in the centre of each of the L's sides.
- By using a chisel, you can remove any pieces of wood (broken fragments) that might get in the way of your work.
- Mount the steel "L" channel onto the rafter or truss, beginning at the end that is the most difficult to access and working your way to the beginning again.
- Put washers and bolts into the holes you drilled in the rafter or truss, and then secure the end of the channel to the rafter or truss.
- When the component's end is in place, you can move the broken piece into position.
- Take a measurement of the distance that separates the steel "L" channel from the rafter or truss.
- After that, use special bolts that are 1.5–2 longer than the space between the two pieces.
- Put the two bolts in the bottom and then tighten them up. After that, you should tighten the bolt that is the furthest away from the break until the other bolt head is approximately a quarter of an inch from the channel.
- Adjust the back bolt so that it presses closely on the steel "L" channel as you tighten it. After that, snug the front bolt until the back one is approximately 1 cm (about 1/4 inch) from the channel.
- Continue to tighten the front and back bolts until the rafter or truss is firmly pressed up against the channel.
- Put bolts into the remaining holes, and then make sure they're nice and snug.
- Keep in mind that you may find it necessary to provide more support to the area.
Fixing Roof Decking
If the roof decking is damaged, it is strongly suggested that you get it repaired by a qualified professional. However, if you follow the instructions below, you can develop a solution that will only be temporary:
- After determining the size of the damaged space in between your roof trusses or rafters, cut a piece of plywood with a half-inch thickness that will fit over the region.
- Attach a piece of stiff Styrofoam measuring 1 inch to the plywood using glue. (Drilling more holes in it might make the problem much more severe.)
- Placing the plywood and the Styrofoam with the side facing up against the roof decking that has been damaged.
- Apply upward pressure to the plywood until the foam is flush with the underside of the roof decking.
- Until you can hire someone who specialises in roofing to fix it, you should use a piece of lumbar strapping to hold the plywood in place.
Fixing A Gusset Plate
Beams and girders are connected to columns through the use of a gusset plate, which can be secured in place with bolts, rivets, welding, or any combination of the three methods. Following these steps will allow you to repair a gusset plate:
- It is necessary to remove the gusset plate from the wood after it has become detached.
- It would be quite impossible to reinstall it, so a plywood gusset that is half an inch thick should be used in its place.
- To secure the gusset to both sides of the wood pieces, a nail gun will need to be used.
When completed correctly, this should replace the strength provided by the original gusset plate.
What If I Can't Repair My Roof?
Do not give up hope if you are unable to fix your roof. In the long run, it may be in your best interest to hire a professional because doing so can save you both time and money.
When a Legacy Service client is in a bind, we are always ready, willing, and able to lend a helping hand. For instance, we will despatch a specialist to your location in order to hold a discussion with you regarding the possibility of replacing your roof.
When it comes to repairing a roof that is sagging or bowing, there are a number of reasons why you should consider hiring a professional:
- It is economical to do so – It may appear that completing the process on your own will save you money, but unless you have prior expertise repairing roofs that have sagged, it could end up costing you more money in the long run. You will be responsible for purchasing the necessary tools and materials, and if anything is not completed in the appropriate manner, it is possible that you will end up having to pay for more damage in the future.
- High-quality materials Roofing contractors who are professionals are able to evaluate which materials are going to be the most effective given the nature of the project and the structure being worked on.
- You don't have to carry out the task on your own! On your day off from work, why don't you just take it easy and relax instead of working on the roof? Fixing the roof is one thing you can cross off your to-do list, and you can do that even if you'd rather take it easy or focus on something else that requires your attention right now.
Should You Replace Inappropriate Roofing Materials?
Every roof is constructed to withstand an extreme amount of weight. As a consequence of this, they instal new, heavier roofing materials. However, using many layers of shingles can cause rooftop sagging, even on roofs that have been expertly constructed. The best solution would be to remove all of the extra shingles and then replace them with new ones.
On the other hand, a property owner can decide to replace the shingles with materials that are not suitable for the allowed weight limit of the roof. For example, clay tiles might be installed in place of hardwood shingles. Switch to using materials that are lighter if the weight of the clay causes the roof to sag.
How Do You Repair Decomposing Roofs?
Joists that have become rotted can cause structural problems, which can then result in the roof sagging. Repairing structural issues and preventing further deterioration can be accomplished by removing the damaged roof, making the necessary repairs, and then filling in the cavity. During the process of installation, the flashing ought to be inspected to determine whether or not it is damaged.

Frequently Asked Questions About Sagging Roof
Sagging roofs are typically caused by insufficient internal bracing or undersized rafters/trusses combined with excessive weight loads. Snow, ice, wind, and even too many layers of shingles can add stress to your roof and cause sagging.
If the roofing materials are not in good condition, replace the shingles and flashing. The sagging may be directly repaired by installing angled braces that shore up the rafters. Alternately, add support to the walls with chains attached to the wall plates.
Steps on how to jack up a sagging roof:
Use a jack-and-post system to jack up the ridge beam slowly. Set up two jacks and posts, so they're evenly spread out from one another in the middle, below the roof ridge beam. Slowly jack up the roof ridge and then tighten the chains each time you jack it up.
You can correct a sagging ceiling by overlaying a two-piece strongback on the joists. The strongback is a plank of wood, stood on its side to provide strength, which sits on the ceiling frame and intersects with each joist at the point of the sag.
It's easy to spot a sagging roof. You will see a dip on the flat part of your roof, a bow in the roofline, or humps and waviness on the roof plane. If the problem is related to the foundation, you will also begin to see cracks on the exterior walls and uneven support beams.
