Flat roofs are durable and practical, but leaks remain one of the most common issues faced by property owners in Markham. Unlike pitched roofs, flat systems don’t shed water easily, so even small weaknesses can quickly turn into major leaks. Understanding the causes and solutions for flat roof leaks will help you know when it’s time to call for professional flat roof repair in Markham.
Common Causes of Flat Roof Leaks
- Pooling Water
Flat roofs are designed with a slight slope for drainage, but clogged drains or poor design can lead to water pooling. Standing water weakens membranes and eventually seeps through. - Cracked or Blistered Membranes
Exposure to Markham’s hot summers and freezing winters causes roofing materials to expand and contract. Over time, this creates cracks and blisters that allow water to penetrate. - Damaged Flashing
Flashing seals vulnerable areas like chimneys and vents. When it fails, water finds an easy entry point. Professional chimney roof repair in Markham ensures these high-risk areas stay watertight. - Clogged Eavestroughs and Drains
Blocked drainage systems force water to pool at seams and corners, increasing the chance of leaks. Routine eavestrough repair in Markham keeps water flowing properly off your roof. - Aging Materials
Flat roofs typically last 15–25 years depending on the material. As membranes age, they lose flexibility and strength, making leaks inevitable without replacement.
Fixing Flat Roof Leaks
- Temporary Repairs: In emergencies, contractors may apply sealants or patches to stop immediate leaks.
- Permanent Repairs: Damaged membranes are replaced, seams resealed, and flashing reinforced.
- Emergency Services: During storms, quick emergency roof repair in Markham prevents water damage inside the property.
- Replacement: If damage is widespread, replacing the roof may be more cost-effective than repeated repairs.
Preventing Future Leaks
- Inspect your flat roof at least twice a year.
- Keep drains and eavestroughs clear of debris.
- Address minor cracks before they become major problems.
- Hire a trusted roofing company in Markham for routine inspections and preventative maintenance.
