Should a Flat Roof be Repaired or Replaced

Flat Roofs Leaks Can be Difficult to Find and Not Worth Repairing?
Let’s hope if your flat roof is leaking, that it can repaired. Repairing a roof is always less expensive than replacement. When it comes to a roof that is flat, sometimes the most difficult part of repairing the roof is actually locating the source of the water penetration. Because flat roofs have a low slope, water can travel a long distance under the membrane before finally dripping down into you attic space. The leak can often be 20 – 50 feet away from the stains inside your property. Roofing contractors who specialize in roofs that are flat charge an hourly rate to find the leak. Once the problem is found, an estimate for repairs and replacement will be provided. In some cases you can spend hundreds of dollars just to get an estimate for a repair that is not worth doing.
Top 4 Reasons Why Flat Roofs Leak
- Roofing Penetrations – including chimneys, vents, air conditioning units are the most common leaky areas. If you a roof that is less than 15 years old, re-sealing or flashing around the penetrations may cure the leaks
- Damaged Membrane – If the flat roof on your home is made of a single-ply membrane, it is vulnerable to damage that is caused by either heavy foot traffic, standing water, weather and age related wear and tear. A damaged membrane will allow water to enter through the insulation, causing a more serious leak.
- Ponding Water – When water starts to pool on your flat roofing system, it can be caused by one of two things. Either over time the roof has settled in a way where the membrane has sunk-in. No roof is totally waterproof like a bathtub. If water stands on the roof long enough it will seep into the structure. If debris is blocking the gutters, downspouts and drains, water will back up on the roof and enter the structure as well. Whatever the case may be, you will need to contact a flat roofing specialist ASAP. Sometimes repairing a roof may be as easy as cleaning your drains.
- Structure of The Roof – If the framing in a flat roof system is not properly installed. Or if the foundation walls have settled in an unfavorable way, there can be roof grade and drainage issues. Roof grading problems will require hiring an engineer and are very complicated and expensive to fix. If a roof has grading issues neither roof repair or replacement will correct the problem. A roof that does not drain properly will always leak.
