Tiles roofs are usually considered a lifetime roof, if installed and maintained properly. There are many brands and styles of tile roofing.
We perform annual roofing maintenance programs which includes the following.
#1 Inspect for missing, broken or cracked tile: replace with new.
#2 Inspect lead flashings for deterioration: seal or replace with new
#3 Inspect for debris build up in the valleys or on the roof; remove debris
#4 If leakage has been reported, then we inspect to see if there is felt paper or if the felt paper is deteriorated; repair or replace with new
#5 Pressure wash any loose moss or algae growth. By performing this annual maintenance, your roof could last its serviceable life.
