From our years of experience, we have compiled the 5 types of roof problems commonly seen in Southern California


Roof leaks are by far the most common type of roof problem homeowners encounter. Exposure to the Southern California heat and sun causes cracking in shingles and tiles, leading to leaks. Poor roof maintenance, improper installation or old roofing materials can also cause leaks. 

Discoloration or water marks on ceilings and walls is a sign of a roof leak. If you observe any of these signs, call a qualified roofing contractor to inspect your roof. The experts at are trained to find the cause of your leak and will recommend effective solutions.

Damaged Shingles

A second common roofing issue seen in Southern California is damaged shingles. Rain, sun, and change in temperature cause damage to shingles over time. 

Damaged or cracked shingles allow moisture to seep into the underside of your roofing materials. This can cause water damage or leaks in your home.

According to, lost shingles might cause your home’s interior air to escape, resulting in increased energy costs once summer arrives.

If you suspect shingle damage on your roof, contact for an inspection.


A third common roofing problem is shrinkage. This type of roofing issue is usually caused by improper manufacturing of material, poor application of the material, or faulty roof design.

Shrinkage is an important issue to keep an eye on as it can lead to a host of other difficulties, such as deterioration, cracking, and the pulling apart of critical components like flashing. Regular inspections and maintenance can identify problems before major damage is caused.

Clogged Gutters

Clogged gutters are an often overlooked roofing problem. Gutters clogged with leaves and other debris can lead to significant roof problems including roof membrane deterioration, which can cause leaks. Additionally, water may eventually seep into the eaves of your home, leading to rot.

To prevent this type of roof damage, inspect your gutters regularly. You may also want to consider installing gutter guards or other gutter protective devices

Shoddy Installation

This final type of roofing problem is unfortunately common in Southern California. Homeowners hoping to save money by hiring inexperienced or unqualified roofing companies usually end up spending more money. According to, “shoddily installed roofs remain one of the most common reasons for long-term complications and short life expectancy and mold.”
