What Diamond Bar Customers Say
"Our flat roof on the garage had been patched five times by other companies. Sunland Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."
"Emergency tarping after a windstorm ripped our ridge cap off. Sunland Roofing & Maintenance had a crew out within three hours and tarped the exposed section before rain moved in. Saved us from interior water damage."
"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."
