A sagging roof in Minnetonka, MN, always causes concern. Many people wonder, “Is a sagging roof dangerous?” While minor sags do not necessarily indicate that your roof will collapse immediately, they can indicate that you should repair or replace your roofing as soon as possible to avoid further damage. Continue reading to learn about your sagging roof repair options in this guide.

What Is a Sagging Roof?

A sagging roof indicates structural instability, which could lead to collapse. Even a slightly sagging roof can cause leaks during severe weather, resulting in mold, mildew, and other storm damage to your property. There is no degree of sagging that is acceptable for a roof.

Is a Sagging Roof Dangerous?

Yes, a sagging roof is dangerous and can cause leaks, which can cause damage to your home, so you must fix it immediately.

If left unchecked, this damage could eventually cause the entire structure to collapse, threatening the rest of your house as well as your and your family’s lives.

What Does a Sagging Roof Look Like?

If you’re concerned about the integrity of your roof, it’s important to know what a sagging roof looks like. A sagging ridge line or a slope in the middle of the roof is an obvious sign of trouble.

You may also notice that some areas of your roof have become wavy or bowed rather than flat or straight. Humps and pillowing are other signs that a roof is sagging. If you notice any of these issues in your home, you should have them assessed by a professional.

What Causes Roofs to Sag?

Excess weight, water damage, poor installation, age, and sinking foundations are the five most common causes of sagging roofs. Let’s go over each one in more detail below.

● Excess Weight

If a roof can only support a certain weight, any additional weight will cause the structure to sag. If your rafters are undersized, there isn’t enough support during storms, or snow and ice are resting on the roof, its integrity may be jeopardized.

● Water Damage

If your roof has suffered from water damage, it may begin to sag as the wood rots underneath. You can fix this by replacing all affected wood with new lumber and checking for roof leaks or cracks in the waterproofing layers above it.

● Poor Installation or Substandard Materials

If there were issues with the materials used in the original construction of your home, or if someone didn’t know what they were doing when they installed your roof, it may begin to sag after a few years of use. That is why it is important to hire a professional contractor to ensure everything is up to code.

● Age

Most asphalt shingle roofs have a lifespan of fewer than 30 years. Years of exposure to abrasive weather and fluctuating temperatures can cause structural integrity to deteriorating, resulting in saggy spots.

● Foundation Sinking

Due to shifting soil conditions or structural issues, your roof may be sagging if your foundation has sunken over time. Your home’s frame may also begin to bow, causing your roof to sink in the center. A professional contractor can inspect your foundation for signs of damage and, if necessary, recommend a repair.

How Can You Tell If Your Roof Is Sagging?

You can tell if a roof is sagging by inspecting it from every angle, beginning outside and working your way up to the roof itself.

● Outside Inspection

Identify the buckling or sagging from the road so you can inspect it more closely from the inside.

● Wall Inspection

Examine the exterior walls for any signs of leaning or tilting. Using a bubble level or plumb bob, check if the walls are plumb (or standing vertically) and the window sills are level (sitting horizontally).

● Attic Inspection

Moving around in the attic can be dangerous if you don’t watch your step. Go up to your attic with a flashlight. Check the roof for signs of wear, such as splits, rot, or broken parts.

● Inspection Safety

When climbing a roof, always use proper safety equipment and have another person nearby in case of an emergency.

Climbing over HVAC ducts can be dangerous due to the presence of asbestos in the ducts or the insulation that surrounds them. If you’re working on an older home, check that the ducts have installed asbestos-safe insulation materials.

What Repairs Can Be Done to Fix a Sagging Roof?

Roofers can usually fix sagging roofs without requiring complete roof replacement. Sagging roof repairs may include:

● Reinforcing the current roof structure

● Installing new supports or struts

● Replacing insulation in the attic

● Installing new sheathing and shingles

Some roofing issues are best handled by a professional. Consider contacting a professional today for a free estimate on sagging roof repair.

When Should You Replace a Sagging Roof?

A sagging roof will worsen and become more expensive to repair or replace. When you suspect your roof is sagging, it’s important to determine whether or not the damage is beyond repair. Roofing professionals can investigate roof sagging, assess its severity, and offer solutions to keep your home and family safe.

If you want to repair sagging roofs, they will be able to tell you whether it is better to install a new roof or repair the old one. Roof replacement is the best option if the roof is long past its lifespan or if there has been significant structural damage.

My experience with ERC could not have been better. Initial contact was Tim--informative, responsive, friendly. The crew was on time, pleasant, and did a great job. Site manager Randy kept things moving and saw it through completion.

We had a such a great experience with ERC from the initial contact through completion of the job! Even though we had a really small job, we felt that we were an important and valued customer from the start. Communication was outstanding and responsive! Every employee we came in contact with was great to work with! They strive for superior customer service and workmanship and from our experience with them, they have surpassed our expectations! We already have a future project list in mind for them to do since we were so happy with their services!

We are very happy – make that extremely pleased! – with the work ERC performed on our house to replace our roof, gutters and fascia. We spent the better part of two years trying to find the right contractor for this project and discussed, met with and got bids from a number of contractors before choosing ERC. ERC was informative, responsive, reliable and professional throughout the entire process, from initial contact through the process for developing the bid, through the completion of the work, and including the communications and invoicing with the insurer. Our project was not an easy “cookie-cutter” project, but ERC did an excellent job of handling all of the complications, as well as some significant weather challenges during the project. Of note, we particularly liked the fact that ERC had a dedicated foreperson on the job (and owner) that served as a single and effective contact person during the project and ensured the quality of the work and that the project was completed in a timely manner. ERC is a family-owned company that clearly takes pride in their work and the results show. We would highly recommend them to anyone based on our experience!

I recently found ERC Construction on Angie's List and hired them for a big home improvement project, including getting a new roof, installing gutters, and fixing some siding. I'm really happy with the amazing work they did. I'm a picky customer who likes to do thorough research before making decisions, so I had six different contractors come and check my roof. After all that, I chose ERC Construction, and they proved to be the right choice. ERC Construction was really professional and did an awesome job communicating with me. They kept me updated throughout the whole project and quickly addressed any questions or concerns I had. They were also flexible and able to meet my request for special shingles that are resistant to hail, have special properties to minimize air pollution (Malarky Vista Class 4 shingles). This choice ended up saving me $450 on my home insurance every year. It shows that ERC Construction is willing to go the extra mile and is committed to delivering great quality and long-term cost savings for their customers. To sum it up, I'm thrilled to recommend ERC Construction for all your roofing and siding needs. Their great craftsmanship, outstanding customer service, and money-saving solutions make them the best in the business. Choosing ERC Construction for my home improvement project was a great decision, and I'm confident they will continue to exceed expectations for anyone who hires them. I am not affiliated in any way with ERC Construction, and I did not get anything in return for this review.

In June of 2022 Christ Church in Otsego, MN experienced significant hail damage that required the replacement of all our roofing and metal siding. We chose ERC as our contractor and couldn’t be happier with the results. From the beginning of the process to the very end Cory Lohse and his team were attentive to every detail from working with our insurance company to picking materials and colors to executing the “extreme makeover” with excellent workmanship that was on time and on budget. I highly recommend that you consider them for your home or business. Great or small they will get the job done! -Greg Pagh, Senior Pastor

We woke up to water coming in through our dining room ceiling due to what turned out to be an ice dam. Tim came out the same day, correctly assessed the problem, and quickly had a team come in to take care of the dam. He was very good with communication and follow-up. I would highly recommend their services.

ERC did a great job! I talked to Tim at ERC when I noticed icicles hanging from my soffit and inches of ice on my roof. I knew I needed ice dam removal. ERC scheduled the service within a day and their crew took care of my issues. The crew let me know exactly what the process was and offered suggestions as the service progressed. I was very impressed by the service and especially the clean up after. I would recommend ERC to my family and friends.

Cory and his team did a great job explaining everything going on and working with the insurance company in getting everything taken care of on replacing our roof. The siding replacement hit a hiccup and took longer than expected and the communication on the delay was a little lacking, but every other interaction was professional and courteous.
