Clients Say It Best!

“A new, sound roof was laid – and just in time. The whole process was completed in just 2 days, and it rained a mere 2 days later. I would strongly recommend Bill and his crew for their workmanship, efficient scheduling and competitive pricing.”

Common Roof Type

In order to match the Spanish style architecture throughout Mission Viejo, most structures are roofed with tile. Tile can slip from position, crack, or break, causing the roof to require inspection every two years, even though it is one of the more durable materials. The Santa Ana winds, which can reach speeds of up to 40 mph, debris in tile valleys, and deterioration from the sun's rays are other things that can affect the condition of your tile.
