Integrity first
If you don’t need a new roof, we’ll tell you, and repair what you have.
About Slatework
Founded by master roofer Dale Hartigan in 1999, Slatework has grown from one truck to 64 people without losing the small-company care.

Our story
Dale started Slatework with a pickup truck, a ladder and a promise: do the job you’d want done on your own house. Twenty-seven years later, more than half of our work still comes from neighbours recommending us.
We stay focused on what we’re good at: roofs, gutters and the parts of your home that keep the weather out. No upselling, no subcontracting, no disappearing after the cheque clears.
