When the Weather Protecting Underlayment of your Concretes Roof Tile has Reached its Expected Life Cycle.
After baking in the hot desert sun, the weather protecting underlayment of your concrete roof tile has more than likely reached its expected life cycle and a roof replacement becomes a consideration.
The fact that the concrete tile covers the underlayment makes it hard to know the roof condition and you will not notice the effects until a leak appears in your ceiling, evolving into a much more expensive repair. We can’t control the weather but we can regulate its impact on our homes with looking out for red flags.
The Tile Roof Institute Installation Manual says that on 4:12 roof slope (33% Slope) or greater a single layer of ASTM D226 Type II (no. 30) (ASTM D4869 Type IV) felt paper or approved equal shall be applied shingle fashion. The industry standard for tile roofing, in short, is one layer of 30lb (ASTM) roofing felt paper. There are many new underlayment materials on the market all claiming to be the newest greatest underlayment replacing 30lb felt paper. There are a plethora of different brands, too many to be compared here.
Tried and True: 30lb Felt paper as specified above in the TRI installation manual is the tried and true underlayment for shakes, composition shingles, and tile roofing. If you want some extra peace of mind SDC Roofing has recommended double felting the roof with two (2) layers of 30lb (ASTM) roofing felt paper. If a heavy wind blows rain and water up the roof slope on your roof tile then you will have two layers of felt paper sealing the nail holes to keep the water out, or if a branch falls and breaks some roof tiles during a rain storm, the two layers of felt paper will carry the load through the rain storm until it is safe to get on the roof and the tile be replaced.
