There’s a good chance that if you are reading this it’s because you live or own a tract home with a tile roof in San Diego.

Even if it’s in a high end part of town, be aware that your roof was most likely installed by a home builder/roofer that took shortcuts to save time and boost profits. Especially homes build during the early 90’s boom, read more about that HERE. Often times the builder and roofer only cared about one thing. The roof lasting 10 years. That’s when they are no longer responsible for it not leaking. Unfortunately, this has plagued San Diego and other cities for several decades. Tile roofs used to last 30+ years because home builders/roofers used to follow manufacturer recommendations. Now they are only looking at the bottom line which means more cost to you for damage/repairs/re-roofs.

Here are some of the issues you can expect to cause the premature failure of these roofs.

One layer of 30# organic underlayment. The absolute minimum required by building code. It rots, cracks and breaks easily. Especially where a tile has slipped out of place or at the transition between the plywood sheathing and starter board at the eaves. This is how roof leaks at the outer walls of a home are usually caused.

Flashing metal run short, so that water runs under the tile instead of on top of it below side walls, chimneys and skylights. This is how roof leaks below chimney and skylights are usually caused.

A “shadow board” at the eaves of the roof which literally causes a dam under the tile, preventing water from draining properly. Leading to rotten fascia and starter boards.

Overexposed tiles that allow water to enter at the nail holes.

Improperly flashing pipes with mortar instead of galvanized or aluminum flashing. Allowing water to run under the tiles.

No hip and ridge nailer boards or no weather blocking installed at the hip and ridge nailer boards. This allows water to run under the tiles.

Inadequate attic ventilation causing super heated air to radiate downward through the drywall ceiling. Not only does this cause your house to come hot due to heat radiating through your ceiling, but it warms the air in the duct-work before it even enters your home, causing you air-conditioning unit to run very hard to keep up with demand.

Vaulted / Cathedral ceiling areas not ventilated at all. This causes heat transfer and moisture build up in behind the drywall ceiling.

Unfortunately, when your tract home tile roof reaches the 20 year mark, it is a ticking time bomb. It’s time to start thinking about correcting all of these issues by having a complete “Lift and Re-lay” performed on your roof. When we re-roof your home with either a “Lift and Re-lay” or all new tile, you can expect the new roof system to last at least 50 years.

All of our tile roof installations and “Lift and Relay” projects are installed per the Tile Roofing Institute Installation Guide. This guide was adopted by and has become California Building Code. Not only does San Diego County Roofing follow these Guidelines, but we are “Tile Roofing Institute Certified”.
