Is there black mold on your Edmonton roof?

• Todays biggest concern among roofing
  contractors in Edmonton is black mold on your
  roof.
• With health being a number one priority in
  everyones life, it really is a serious issue.
  With flat roofs (Tar gravel), there is a higher
  risk of black mold being present, whether in the
  walls or in the insulation. If your home was not
  built correctly right from the beginning with
  proper venting, then you need an expert to
  inspect your house as soon as possible.

• In our experience it seems that half the
  houses designed with flat roofs in Edmonton, most
  from over 30 years ago, were vented incorrectly.
  Houses vented correctly usually have a continuous
  aluminum ridge vent running along the whole
  length of the peak. With this continuous vent is
  also a vented soffit. This being said, if you
  have a split or a hole on the roof, a
  professional roofing contractor will simply patch
  the roof, and if properly vented everything will
  dry up soon in a natural state.

• Roofs that arent properly vented will end up
  trapping moisture and hence will turn into black
  mold. I am not an expert on black mold, but a
  proper building inspector or in particular a flat
  roof inspector should be able to give you the
  correct advice. Any credible roofing contractor
  in Edmonton should be able to work with a
  qualified inspector, bearing in mind that there
  are roofing contractors that wont work with any
  roofing inspectors.

• My best personal advice about a roofing
  contractor that wont work with a qualified
  inspector is to take this as a red flag. We are
  here to correct, fix, and give you the proper
  service that you are paying for. That being said,
  I dont want to scare or panic anyone just
  because a leak has developed.

• In over the 30 years of roofing experience, I
  find it is usually the roofs that have been
  ignored for lack of maintenance that pose the
  most risk.
