We had Penfolds install their EcoRoof Rubber Shingles 8 or 9 years ago. We were thoroughly satisfied with its installation and with the product. When a leak recently developed near a chimney, we contacted Penfolds and their response was both prompt and effective. Phil and Ian determined that the probable fault lay not with the roofing but with the chimney itself. A faulty chimney cap was quickly detected and repaired (result: no more leak) and deteriorating chimney counter flashing also was identified. Despite the fact that Penfolds typically contracts out any chimney work, Ron (Service Supervisor) arranged for Phil and Ian to correct the problem. The replacement counter-flashing was vastly superior to the original, the quality of their work was outstanding and the obvious integrity of all three (Ron, Phil and Ian), quite exceptional. Overall, I recommend Penfolds Roofing without hesitation. They may not be the cheapest, but their accountability is worth every penny!
