Common Causes of Pooling Water on a Roof

Having the right “roof over your head” is essential to keep the elements away, but having one that isn’t working is like using a broken umbrella.

Pools of water tend to form in these holes. If they don’t go away, they become stagnant and cause even more damage.

Read on to learn the most common causes of pooling water on your roof and who to call to fix it.

Poor Design

Pooling water almost always comes down to a mistake made during design and installation. Even a small mistake in the shape can lead to major problems.

This is just one reason why you should never try DIY roofing. It decreases the lifespan of your roof and puts your own life in jeopardy.

Call a professional to get the installation right the first time. Take the time to find the right one by researching them, checking their paperwork, and getting an estimate.

Age and Foundation

Even the most expertly crafted designs suffer signs of aging that could leave them prone to water pools. 

You may need new shingles, notice stains, or see other signs of roof wear and tear. These can be repaired rather than replaced.

Time will also affect your roof in more serious ways. Mold or moss starts to grow. Sagging and settling of the foundation changes the slope. These issues suggest that you need a roof replacement.

New Features

New roofing can also cause pooling water. This includes full replacements and features such as a skylight or plumbing vent. 

Proper installation is essential to prevent dips in your roofing. They create ponding water that will only get worse over time.

Crushed Insulation

Homes without insulation lose 25% of their heat from the roof. Insulation is made of multiple layers to prevent this loss and keep warm air inside.

The problem is that these layers are malleable and tend to become uneven under heavy weight. Most roofs can handle 20-25 pounds per square foot, but they bend under heavy:

  • Foot traffic 
  • Stored items
  • Piles of snow
  • HVAC equipment

Pooling water begins to form in sunken-in areas. It eventually becomes ponding water because it can’t evaporate.

Lack of Drainage

Clogged or slow-moving roof drains can’t move water out. An improper connection point between flat and sloped roofs causes the same problem. Large flat roofing may need a siphonic drain to keep up. 

There also needs to be a proper roof drain slope that guides extra water. You’ll get pooling water at the lowest point if it:

  • Doesn’t lead to the drains
  • Is inconsistent
  • Is too flat or too low

HVAC Leaks

Heavy HVAC equipment creates dips in your roof. These can become water pools.

The equipment is also prone to leaks and condensation if it’s broken or not draining. You’ll need an HVAC professional to fix the equipment and a roofer to repair any damage they cause.
