Is A Flat Roof
Flat?

Flat Roof

While a flat roof may look flat, they have been engineered to slope towards drains and scuppers. Some have roofing materials specially designed to create these slopes and must be installed like placing giant puzzle pieces in the right place. Whatever the method, the result is the draining of water off the roof.

Drains and Scuppers

Drains and Scuppers

The drain's role is to provide the removal of water as quickly as possible and should be inspected for blockages, frequently. It should be part of a regular roof maintenance program.

Leaks and Moisture

Leaks and Moisture

The decking supports the roofing membrane that covers it. The function of flashing is to provide a watertight connection between the roof and projections. Many early roof leaks are the result of flashing problems and prompt repair will extend the roof's life

Blow Off and/or Tenting

Blow Off and/or Tenting

The use of gravel stops and roof edge is done to contain the gravel and prevent blow-off but it also creates breaks that can allow water penetration. Proper placement is very important.

Ponding
Water

Ponding Water

Water should drain completely within 48 hours after a rain. If water is left to pond, it can lead to roof sag, increased leaks, plant growth and an increase in the rate of deterioration of the roofing material.

Lack of Maintenance

Lack of Maintenance

A flat roof should give you decades of service. However, like any part of the building, it need regular maintenance. Failure to check your roof can be very expensive.

Blistering

Blistering

When the layers of felt and/or substrate separate, air is trapped between the layers. The roof feels spongy and over time with the changes in temperature, the separation increases.

Membrane Punctures

Membrane Punctures

These can be found where blisters have broken, nails and fasteners have risen up or membrane has shrunk and pulled away from the edge. You can assume a great deal of water has penetrated the membrane.

Roof Mounted Equipment

Roof Mounted Equipment

Any roof equipment should never be placed directly on a roof. They should be mounted and curbed to prevent roof failure.

Perimeter

Securing

Perimeter Securing

Securing the perimeter of a roof is very important for maximizing the life of the roof. It prevents leaks, blow off and membrane detaching.

Deck
Repair

Deck Repair

Metal decks can be affected by water leaking. This deteriorated and rusts the deck. Often, the damage can be repaired by aluminizing the surface rust.
