Are you worried about the signs and symptoms of damage, leaks, or water damage in your flat roof? Are you confused about your next step? Then this blog is for you.
Flat roofs are an aesthetic and convenient choice for homeowners and business owners in Toronto. Their glossy design, low maintenance, and flexibility make them the best roofing options for urban environments.
However, they have their own set of challenges. From water pooling to cracks resulting from freeze-thaw cycles, flat roofing systems are particularly vulnerable in a metropolis known for its harsh winters and unpredictable weather shifts.
Understanding the issues and solving them early can prevent expensive maintenance. As one of the best flat roofing companies in Toronto, here we will discuss the most common flat roofing issues and their solutions.
1. Water Pooling or Ponding
The Problem:
Flat roofs are constructed with a slight slope to facilitate water drainage. If there is any error during the construction of the flat roof, such as poor installation, or if the slope is compromised due to debris buildup or sagging, water starts to pool, increasing the risk of leaks and structural damage.
Solution:
- Choose experienced and licensed installers
- Install tapered insulation to redirect water flow
- Clear and maintain all drains
- Regrade areas where ponding may happen
- Roofing companies in Toronto apply waterproof membranes for added protection
2. Cracks and Blistering
The Problem:
Expansion and contraction in the roofing materials are very common issues in Toronto’s freeze-thaw cycles. Over time, this will generate cracks, blisters, and bubbling on the roof floor.
Solution:
- Patch minor cracks with the use of roofing cement or coatings
- Replace broken membrane sections
- Consider complete membrane replacement for ageing roofs.
3. Leaks and Moisture Intrusion
The Problem:
Flat roofs are more vulnerable to leaks, especially if the waterproofing layers have deteriorated. Moisture penetration can lead to mould growth, insulation damage, and interior ceiling problems.
Solution:
- Flat roofing companies in Toronto conduct a moisture inspection to discover hidden problems
- Seal seams and joints nicely
- Use innovative waterproofing systems to add safety
- Ensure expert maintenance to prevent recurrence
4. Damaged or Failing Flashing
The Problem:
Flashing guards the edges and joints of your flat roof, especially around vents, chimneys, and skylights. Over time, flashing can become loose, corroded, or improperly sealed.
Solution:
- Reinstall or replace flashing as required
- Use durable, UV-resistant flashing objects
- Regular checkups to detect and address small issues
5. Organic Growth and Vegetation
The Problem:
Standing water and shade can create a breeding ground for moss, algae, or plant roots to develop, especially if not checked properly.
Solution:
- Roofing companies in Toronto remove all types of growth and debris
- Clean the roof with antifungal remedies
- Improve drainage and sunlight exposure where viable
