What affects the price
Roofing repairs vary depending on the extent of the damage and the materials involved. If your leak is isolated to a few shingles, the fix is usually straightforward. However, if the underlying decking is rotted or the flashing around your chimney is compromised, the labor and material needs increase. Steep roof pitches can also add to the cost due to safety requirements. We assess your unique situation to give you a clear picture of what is needed. Exact pricing confirmed free on the call.
