What Castro Valley Customers Say
"We got three quotes for a full tear-off and Alleghany Roofing & Maintenance was the most thorough. They showed us the rotted decking in the photos before replacing it. New Timberline HDZ shingles look great."
"Had a bad leak around the chimney flashing after a storm. Alleghany Roofing & Maintenance came out next day, found the failed step flashing, replaced it, and sealed everything properly. No more dripping. Solid work."
"Their crew showed up at 7 AM, tore off the old roof, replaced eight sheets of plywood, and had new shingles down before dinner. Jobsite was cleaner when they left than when they arrived."
