Flat roofs are a popular choice for many homes and commercial buildings, especially in areas like North Vancouver and Maple Ridge. They offer a clean, modern look and are easier to install than sloped roofs. But like any roofing system, flat roofs come with their own set of challenges.
If you have a flat roof, it’s important to know what problems to look out for and how to fix them before they get worse.
1. Poor Drainage
One of the most common issues with flat roofs is that water does not drain properly. Unlike sloped roofs, water doesn’t naturally slide off a flat roof. If your drainage system isn’t working well, water can pool on the surface, leading to leaks or structural damage over time.
Tip: Regularly check your drains and gutters for blockages, especially after heavy rain or snow. If you notice water pooling on your roof, it might be time to install more drains or improve the slope slightly for better water flow.
2. Leaks and Water Damage
Flat roofs are more likely to leak than pitched ones, especially if the roofing material is aging or damaged. Even small cracks or punctures can allow water to seep in, causing damage to the layers underneath or even to the inside of your home or business.
Tip: Look for signs of water stains on your ceiling or walls. If you see bubbling paint or mold growth, it’s a red flag. Have a professional inspect your roof and seal any cracks or holes with high-quality roofing materials.
3. Blistering and Bubbling
Over time, trapped moisture or air can cause the roofing material to blister or bubble. This is not just a cosmetic issue, it can lead to bigger problems like roof leaks or faster wear and tear.
Tip: If you see blisters forming, don’t ignore them. A roofing expert can cut away the damaged area and patch it properly to prevent further issues.
4. Flashing Damage
Flashing is the material that seals the edges of your roof and around things like vents, skylights, and chimneys. On flat roofs, flashing is essential to keep water out. But over time, flashing can crack, lift, or rust.
Tip: Check your flashing regularly, especially after storms or strong winds. If you notice gaps or cracks, get it repaired quickly before water gets in.
5. UV Damage and Aging
Flat roofs are exposed to a lot of sun, and over time, UV rays can break down the roofing materials, making them brittle and more prone to cracks or leaks.
Tip: Consider using UV-resistant roofing products like torch-on membranes, which are designed to withstand sun exposure. Also, routine inspections can help catch signs of aging early so you can extend the life of your roof.
6. Poor Installation
Unfortunately, some flat roofing issues stem from poor installation. If the materials weren’t laid correctly or the slope wasn’t calculated right, problems can show up quickly, even on a newer roof.
Tip: Always work with a trusted and experienced roofing company to make sure your flat roof is installed the right way from the start. A properly installed flat roof should last many years with minimal issues.
