Don’t Risk Your Flat Roof – Act Now
Leaks don’t wait, and every day of delay could mean more hidden damage.
<<Flat roofs need regular inspections to stop leaks, avoid structural damage, and prevent costly repairs. A proper inspection helps catch problems early—before they turn into bigger issues.>>
In this guide, we’ll walk you through the flat roof inspection process step by step. From safe access and surface checks to seams, drainage, and roof penetrations, you’ll see what a professional inspection includes and why it matters.
Safety is always the top priority. We move carefully across the roof, placing one foot directly in front of the other. This lets us detect weak spots or damaged plywood. By doing this, we keep both our team and your property safe.
Once safety is confirmed, we examine the roof surface. We look for debris and standing water—common signs of deeper problems like sagging plywood or poorly installed HVAC units.
We use a special hook tool to check seams. By inserting it at a set angle into randomly selected seams, we can find weak spots or areas under tension, especially in places where water tends to pool.
We inspect edge metals and coping by gently lifting seams to confirm they’re sealed properly. The coping on parapet walls is then checked to ensure it’s secure and watertight.
We closely inspect drains and scuppers (on-wall or through-wall). Cold welds can weaken over time, especially in freezing weather. Areas around drains are examined for standing water, which is a warning sign of drainage problems.
Any penetrations, such as exhaust pipes or HVAC equipment, get special attention. We check the sealing and insulation, since poor sealing is one of the most common causes of leaks.
We recommend routine cleaning, quick repairs when issues appear, and scheduled inspections to stay ahead of these problems.
Small details missed today can turn into major leaks tomorrow.
