How to Spot and Address Structural Issues During Roof Repair
Structural damage to a roof can cause leakage and more serious problems. Regular inspections and prompt professional assistance can help prevent this and save money on roof repair costs.
Look for water stains in the attic and ceiling, and examine the condition of the roof trusses or rafters. This will identify structural issues and allow for early repairs, preventing slipped tiles.

Cracked or Damaged Shingles
Tiny holes in your roof shingles may not seem like much of a problem, but the longer they go unrepaired, the more damage they can do. In addition to letting water in, they also leave your home at risk for mold and mildew growth.
Shingle cracking and shingle splitting are also serious problems that need to be addressed promptly. The latter happens when a shingle’s asphalt layer separates into two or more pieces, leaving the underlayment exposed and vulnerable to leaks.
Other shingle issues to keep an eye out for include granule loss (you’ll see these in heavy clumps on the ground) and heat blistering, which looks like small bubbles on the surface of your shingles. This condition leaves your roof more vulnerable to UV damage and could eventually lead to leaks.
Sagging Roof Deck
A sagging roof deck can lead to structural damage in the house. Slight sagging in one or more areas isn’t necessarily a big problem, but severe sagging indicates that the rafters and trusses are starting to fail.
Sagging can be caused by weather, poor roof installation, and other issues that weaken the roof structure. It can also be a sign of an infestation, including pests like rats and squirrels that chew through the wood to create nests.
Regular maintenance and inspections help to catch issues like a sagging roof deck early on. Addressing these problems promptly can save homeowners a lot of money and stress in the future. Structural issues that aren’t addressed will get worse over time, putting the home and its inhabitants at risk.
Warped or Uneven Roof Lines
Moisture, rot and mould weaken framing members over time. This can lead to sagging or uneven roof lines.
Uneven ridge lines or dips in the roof surface can indicate structural issues that need to be addressed by a professional. If you see a low spot in your roof that does not resolve itself, call a trusted roofing contractor.
Look for rafter ties that are cracking or pulling loose. These wood pieces keep the rafters and exterior wall top plates connected and should be securely in place. Also, feel the insulation boards to make sure they aren’t sagging or unadhered.
A sagging or uneven roof can lead to water leaks and serious structural problems that can threaten the integrity of your home. A professional can identify and address these issues before they become more severe.

Debris or Moss Buildup
Moss growth on a roof isn’t just unsightly it poses significant structural risks to your home. First of all, it traps moisture which eats away at the outer layer of your roof shingles and the structure beneath, possibly leading to holes in your roof and rot.
The moss also blocks the flow of water off the roof, causing drainage issues. This creates a continual source of excess moisture and can cause problems such as ice dams in the winter.
Keeping up with regular roof cleanings can help prevent the onset of moss and other organic debris on your roof. However, if you find an area of your roof that is covered in moss or other organic debris, you should consider getting it cleaned professionally.
Unusual Sounds
There are plenty of strange sounds that can arise from the roof of your home. Some of these sounds are normal and others indicate that something is terribly wrong.
Creaking during heavy winds is one thing—it's perfectly natural for wood structures to creak under pressure. However, if your roof creaks with even a slight breeze or in mild weather conditions, it's time to call a roofer to assess the structure.
Another common sound is popping noises that occur when temperatures drop at night. This is also a result of temperature changes that cause solid materials like lumber to expand and contract.
Fortunately, this type of noise is easily addressed by adding diagonal bracing to the rafters using large screws instead of nails. This will transfer the pressure to other rafters and help to prevent further structural damage.
