Should you notice these stains, contact a professional immediately to determine whether this is a leak in your roof, HVAC unit, or a plumbing issue.




Damage to your roof could eventually turn into a leak in your building. It is necessary to be up to date with the upkeep and maintenance of your roof to prevent both damage and water leaks. This damage can come in many forms like ponding water from poor drainage, aged and weathered membrane that results in membrane blisters or cracking, open seams, damaged flashing, or tears or holes in membrane.
