- Diagonal cracks starting from corners
- Stair-step patterns in brick or masonry
- Cracks wider than ¼ inch
- Cracks that are wider at the top than the bottom
Crack Type
Possible Cause
Concern Level
Horizontal
Foundation stress, water pressure
High – needs immediate attention
Diagonal
Uneven settling, soil movement
Medium to High – professional evaluation needed
Vertical
Normal settling, drywall seams
Low to Medium – monitor for changes
Stair-step
Foundation movement, soil issues
High – structural assessment required
“Regular inspections and prompt addressing of any cracks can help prevent more serious structural problems”.
If cracks are paired with other signs, like sticking doors or uneven floors, it’s a strong indicator of structural issues that need expert evaluation. Fixing foundation cracks early can save your home from severe damage.
To minimize these risks, address drainage problems and consider scheduling yearly inspections to spot potential issues before they worsen.
These cracks often appear alongside uneven floors – our next warning sign.
2. Uneven or Sloping Floors
After wall cracks, uneven floors are often the next sign of structural issues. These can appear as dips, waves, or noticeable gaps between the floor and baseboards. Here’s how to assess the problem:

Uneven surfaces, bowed rafters
Moderate to High
Water Damage
Drooping ceilings, moisture stains
High – Progressive damage
Foundation Settlement
Combined roof and wall issues
Severe – Structural concern
Areas to Keep an Eye On
The ridgeline, where the roof slopes meet, is a key area to monitor. A straight ridgeline is essential; any bends or dips suggest structural problems.
Other warning signs to watch for:
- Sagging along the roof’s edge
- Deformed interior ceilings
- Bowed or stressed rafters visible in the attic
- Gaps forming between the roof and exterior walls
The Role of Weather and Prevention Tips
Heavy snowfall can worsen roof stress. Did you know that one cubic foot of wet snow can weigh up to 20 pounds? Regular snow removal is essential to avoid overloading your roof.
“Ignoring a sagging roof can lead to further structural damage, compromised stability, and potential safety hazards. It can also result in water intrusion, leaks, and even partial collapse of the roof”.
When to Call a Professional
If you notice sagging, don’t wait. Document any changes, check for water damage, and consult a structural engineer right away. A professional evaluation can help you address the problem before it worsens.
Sagging roofs often coincide with other issues, like gaps between walls and ceilings. We’ll cover that next.
5. Gaps Between Walls and Ceilings/Floors
Gaps between walls and ceilings, much like sagging roofs, often point to foundation stress. These spaces suggest possible structural movement or foundation issues that need prompt attention.
Common Gap Patterns
Location
Possible Cause
Wall-Ceiling Junction
Foundation settling or roof structure problems
Wall-Floor Connection
Uneven foundation shifts or floor joist issues
Corner Joints
Structural movement or stress on load-bearing walls
Around Door Frames
Foundation settling causing misaligned frames
Identifying the Gaps and Their Causes
A level or straightedge can help detect subtle gaps that aren’t immediately obvious. In many cases, these gaps occur alongside sticking doors or windows (as discussed in Sign 3). Joints where different materials meet are often the first to separate during structural shifts.
Main Causes:
- Foundation settling
- Moisture-related damage
- Stress on load-bearing walls
- Poor construction practices
Why You Need a Professional Evaluation
Structural engineers can determine whether these gaps are due to ongoing structural movement or just seasonal changes.
Risks to Your Home
- Weakening of the building’s structure
- Increased chances of water leaks
These gaps are often an early warning sign before more visible problems, like cracked exterior bricks, start to appear – stay tuned for that in the next section.
