Watershed Roofing & Exteriors are fully trained and qualified to perform affordable, thorough flat roof repairs and flat roof leak repairs in South West Ontario.
Routine flat roof repair prevents extensive damage
Your roof not only covers your building, but protects its structural integrity as well. All flat roof owners will face ponding water. It comes from having a roof with little to no sloping. If left untreated, these pools of water can lead to roof leaks that can lead to water damaged walls, destruction of interior finishes and furniture, and encourage the growth of unhealthy mold and mildew.
Routine inspection and repair can prevent personal and related injuries and expensive restorations.
Save on the expense of roof replacement

Faulty installation, weather damage and low grade roofing materials can affect the performance of your flat roof. Regular inspections help identify problem areas while they can still be fixed. Blisters or cracks can be attended to individually and do not require installation of a new roof. Trying to save on small repairs can result in the huge expense of entire flat roof replacement.
Contact us to talk to one of our certified team members to determine how our efficient repair service can prolong the lifespan of your flat roof.
