A sagging roof is more than just a cosmetic problem—it’s a serious structural issue that can put your entire home at risk. In Markham, heavy snow loads, aging materials, and water damage are common causes of roof sagging. Identifying the warning signs early and scheduling professional roof repair in Markham ensures your home remains safe and secure.

Causes of a Sagging Roof

  1. Water Damage
    Leaks from damaged shingles or poor flashing weaken roof decking over time.
  2. Heavy Snow Loads
    Markham winters often bring heavy snow, which strains the roof structure and accelerates sagging.
  3. Poor Ventilation
    Trapped moisture in attics encourages rot in wood rafters and decking.
  4. Aging Roofs
    Older materials lose their strength, making sagging more likely.
  5. Foundation Issues
    In rare cases, foundation movement can shift roof supports, contributing to sagging.

Warning Signs of Roof Sagging

  • Uneven rooflines visible from the street.
  • Bowed or drooping sections in the attic.
  • Cracks in interior ceilings or walls.
  • Leaks or water stains inside the home.

If you notice these symptoms, call a licensed roofing company in Markham immediately.

Professional Repair Options

  • Structural Reinforcement: Adding new rafters or beams to strengthen the roof.
  • Decking Replacement: Removing and replacing weakened plywood.
  • Shingle and Flashing Repairs: Fixing leaks that caused the initial damage.
  • Drainage Improvements: Scheduling eavestrough repair in Markham ensures proper water flow away from the roofline.

Emergency Sagging Roof Repairs
