When a roofer arrives to inspect your home for leaks, they don’t start guessing, they go straight to the most common problem areas. Over time, certain parts of a roof are more vulnerable to wear, weather, and water intrusion. By understanding where professionals look first, you’ll gain insight into how roof leak detection works, and maybe even prevent future damage. Today, we at Suburban Roofing would like to share common leak-prone areas.
Flashing Around Chimneys & Vents
Flashing is a thin material, usually metal, that roofers install around roof penetrations like chimneys, vents, and skylights to keep water from entering. Over time, flashing can become loose, corroded, or improperly sealed. Roofers always examine flashing first because a small gap or rusted spot can let water seep in, especially during heavy rain or melting snow.
Valleys Where Roof Planes Meet
The valleys of a roof, the channels where two slopes meet, are designed to direct water off the roof. Because they handle a high volume of runoff, they’re under more stress than other parts of the roof. Cracked sealants, debris buildup, or damaged shingles in valleys are frequent sources of leaks. Roofers inspect these closely to ensure water is flowing properly and not pooling or backing up.
Around Skylights & Dormers
Skylights bring in natural light, but if not properly installed or maintained, they can become leak hazards. The edges around skylights, dormers, and other architectural features are notorious for collecting water and debris. Roofers inspect the sealant, flashing, and frame to ensure everything is watertight.
Eaves & Roof Edges
Roof edges and eaves are exposed to wind-driven rain and ice dams, especially in colder climates. When water backs up under the shingles or ice pushes its way under the roofing material, leaks can occur. Roofers often find leaks originating here due to worn-out underlayment or missing drip edge flashing.
Plumbing Vent Boots
The rubber boot or metal flashing that surrounds a plumbing vent pipe can crack or deteriorate over time, letting water leak in around the pipe. Roofers always check these boots during a leak inspection because they are a common failure point, especially on older roofs.
Missing or Damaged Shingles
Loose, missing, or curled shingles can allow rainwater to sneak underneath and soak into the roof deck. This can cause slow, hidden leaks that damage insulation, ceilings, and walls. Roofers quickly spot these issues and determine whether repairs or full replacement is needed.
