Roofing Ventilation and Insulation

Your San Diego home is protected by a combination of roofing materials, ventilation, and insulation. Even if you have a fairly new roof, without proper ventilation or insulation, your home will have trouble controlling the temperature and humidity inside the house. That’s why we highly recommend a ventilation and insulation inspection. Take a look below to discover how Roofing Specialists of San Diego can help!

Roof Ventilation Problems

A roof and attics’ ventilation are among the most important components that contribute to the longevity of a roof. Without proper ventilation, a home can begin to emit a musty smell. It can also cause thousands of dollars in roofing repairs if the roof experiences damage that is a direct result to insufficient ventilation. In fact most asphalt shingle manufacturer’s warranties become void if damage is caused by improper ventilation.

Roof Ventilation Solutions

There are a number of ventilation products and techniques that Roofing Specialists of San Diego can use. The majority of building codes and roofing material manufacturers require a specific amount of ventilation in an attic.

Title 24 Areas in San Diego County

Codes, also referred to as Title 24, are consistently updated. As of July 1, 2014, attic insulation will change to r-38 and roof vents will need 1 vent per 150 square foot of attic space. Surprisingly, less than 10% of homes in San Diego currently have an attic that is up to code. Keep your home up to code by giving Roofing Specialists of San Diego a call today.

Attic Space Venting Options

Depending on the type of space, we can install the following ventilation options in a residential attic:

Soffit Vents/Insulation Baffles

In order for your ventilation system to work, it needs to have a point of entry and a point of exit for air flow. Soffit vents allow convective air to move from the soffits to the ridge of the vent. To prevent the insulation in the attic from being restricted, insulation baffles are installed where the attic floor meets the roof line.

Ridge Vents

This is a ventilation strip that Roofing Specialists of San Diego places along the ridge line of your home. Before we install the ridge vent, we cut a 1’’ wide strip of roof decking from both sides of the ridge line to allow air to move through the vent.

Gable Vents

We install this type of vent in the gable ends of a home or building. Gable Vents are typically louvered vents that draw air out of the attic space and block moisture from entering. This type of ventilation system helps with fire-hazard prevention.

Additional Venting Options

To draw air out of your attic, Roofing Specialists of San Diego can also install fans and/or vents on your roof. For example, we can use whole house fans, powered attic fans, louvered dormers, mushroom vents, and more to ventilate problematic areas.
