What Los Alamos Customers Say
"Had a bad leak around the chimney flashing after a storm. Grenville Roofing & Maintenance came out next day, found the failed step flashing, replaced it, and sealed everything properly. No more dripping. Solid work."
"They replaced all our gutters along with the roof. Seamless aluminum, properly pitched. Water actually drains into the downspouts now instead of overflowing at every seam. Night and day difference."
"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."
