Flat roof insulation may seem like a nuisance. After all, why would a flat roof need insulation? There is only a small level of space involved. Just how much heat and dampness can possibly be trapped in such a small area. Furthermore, is it really necessary to insulate a flat roof? Well, you might like to know that the spaces inside a flat roof are just as important as the spaces between any other roof area, including sloped roofs. An inadequate amount of insulation can do a large amount of long-term damage, just like any other structure that requires insulation.
Why is insulation actually needed for a flat?
In fact, the need for proper FRI far outweighs the need for insulation for sloped roofs. Why? Because flat roofs have an extreme exposure to the elements of extreme heat and cold. And they are FLAT. Unlike shingled roofs, water, ice, and heat seriously play havoc. There is no release of pressure or run-off.
Look out for the damage!
Because of the design, the no-slope, the flatness of it all, damage is more likely to occur. And because many homes and commercial buildings have large amounts of square footage benefit the flat it can easily become a serious trap for major (and often unseen) damage. All the moisture from the kitchens and bathrooms and laundry rooms usually get stuck. Unless the insulation is really up to par and the ventilation is also where it bought to be, the odds of reckless flat roof damage is almost inevitable.
Bottom line – Is flat roof insulation worth your time?
Most professional insulators agree that is most definitely worth the time. But it needs to be done right. Insulation goes hand-in-hand with ventilation. Both insulation and ventilation need to work in unison. Think of this as a symbiotic relationship both working together as one. It is actually a very beautiful working relationship. The insulation protectors and shields while the ventilation releases and provides much needed new air for the flat roof to breath. When this relationship is designed to work at a 50% by 50% ratio the conditions can become extremely optimized for amazing results.
The results show in the form of longering roof materials, big savings in energy cost during the summer and winter months, and much better conditions for you as a human while existing and living your life in your house or building. And over the years this added comfort and energy cost savings is certainly worth the investment and time of properly acquiring good FRI and ventilation.
In conclusion, insulation (and proper ventilation) can make the difference between a happy, comfortable living space or a very unhealthy, uncontrollable atmosphere that will always results in constant damage and ongoing repair and maintenance costs, years after year. Do yourself a huge good turn by hiring a professional to thoroughly check the conditions of your flat roof. It will pay big dividends for you and your peace of mind.
