Ventilación de Áticos

NO reutilices las salidas de ventilación del ático

Hay una razón por la que los fabricantes de tejas advierten sobre esto.

Cada vez que se reemplaza un techo, también deben reemplazarse las salidas de ventilación del ático, aunque parezcan estar en perfectas condiciones.

Una pregunta que surge con frecuencia durante las sesiones de preguntas y respuestas en nuestros seminarios es: “Si vamos a instalar un techo nuevo y las salidas de ventilación del ático existentes parecen estar en buen estado, ¿podemos volver a instalarlas con el nuevo techo?” Nuestra respuesta siempre ha sido clara y consistente: No.

Desde hace mucho tiempo, en AirVent sostenemos que reutilizar las salidas de ventilación del ático es una mala idea, sin importar lo intactas que aparenten estar. Y no estamos solos. Los fabricantes de tejas comparten esta postura.

La Asphalt Roofing Manufacturers Association (ARMA) —la voz oficial de la industria de las tejas— lo expresa claramente en su Boletín Técnico: Por qué la ventilación es importante:

“Al realizar un retechado, se deben reemplazar los dispositivos de ventilación ubicados en el campo del techo (es decir, respiraderos estáticos, respiraderos de cumbrera). Es posible conservar las entradas y salidas de ventilación que no estén en el campo del techo (es decir, respiraderos de sofito, respiraderos de hastial), siempre que sigan siendo funcionales al finalizar el retechado.”

¿La conclusión? Si se van a instalar tejas nuevas, también deben instalarse nuevas salidas de ventilación del ático. Aquí están las razones:

1. Riesgo de Daño Durante la Remoción

Al retirar las salidas de ventilación existentes, es común que sufran daños físicos, incluso si no son visibles de inmediato. Un respiradero dañado no puede cumplir su función de manera confiable.

2. Orificios de Fijación Comprometidos

Los respiraderos originales ya tienen orificios de los sujetadores utilizados en la primera instalación. ¿Puedes garantizar que esos mismos orificios se reutilizarán exactamente igual? ¿Podrían los orificios restantes convertirse en puntos de filtración de agua? ¿Y los puntos de fijación originales seguirán siendo seguros en una segunda instalación?

3. Proteger el Valor de un Techo Nuevo

Un techo nuevo es una gran inversión, que a menudo cuesta miles de dólares. Reinstalar respiraderos usados reduce el valor total y el rendimiento a largo plazo de esa inversión.

4. Reclamos de Seguro y Objeciones

Hemos escuchado casos donde seguros solicitan reutilizar las salidas de ventilación existentes durante reclamos por daños por tormenta. Nuestra recomendación: remítelos al boletín de ARMA. Si el fabricante de las tejas nuevas advierte en contra de reutilizarlas, entonces todo el sistema, incluida la ventilación, debe actualizarse por completo.

En resumen: No reutilices las salidas de ventilación del ático. Las tejas nuevas merecen respiraderos nuevos. Hacer lo contrario compromete la integridad del sistema de techado… y la tranquilidad del propietario.
