In terms of maximizing living space within a home, a “warm” roof is growing in popularity. This is the most cutting-edge home improvement technology that creates a much more efficient system in comparison to more conventional designs. It overcomes the risk of condensation by propelling humidity to the outside of the material. Basically, a warm roof system uses a “breathable” layer, or membrane, that hinders air and moisture from being trapped within the attic space that could otherwise result in the decay and rotting of wood structures.
Conventionally, flat or pitched coverings are comprised of timber decking with a water-resistant layer placed on top of it; however, a new warm roof system consists of different layers that effectively eradicate the possibility of condensation. It would be wise to contact a professional contractor to examine and assess the roofing structure to determine whether it has the proper layers of protection.
Configuration
The best solution to prevent damage caused by condensation is to install a warm roof configuration. Such a system is positioned and layered accordingly to eliminate dampness. From the outmost part of a room upward, on top of the ceiling material and attached to it is wooden supporting joist; above it is layered with structural decking to support the vapor control layer that is placed beneath the insulation to restrict vapor from coming in contact with the insulation membrane.
Another piece of plywood can be placed to overlaps the insulation water-resistant membrane, which is then followed by the surface protection. In brief, from the inside of the attic down to the inner ceiling is the following in order: surface material; counter and tiling battens; vapor control layer/insulation membrane; decking; wood joist; and ceiling material.
Functionality
A warm roof has an insulation membrane that is laid on the outer side of the structure, which means that the structural decking is inside; this prevents any of the decking material from becoming damp and increasing its life expectancy immensely. Since the decking has no opposing temperatures such as cold from the outside environment or warmth built up in the attic space, the possibility of condensation is avoided. Since this design eliminates any dew point at the decking level, ventilation is not necessary, which decreases utility costs. Equally important, a warm roof creates a better level of air-tightness by controlling air-movement, thereby decreasing heating and cooling expenses.
Benefits
As with any other structure, this has its own advantages to benefit building residents. Primarily, it offsets the energy bill since the need to add or decrease heat is eliminated which in turn improves the comfort level of the residence. It also eliminates structural damage caused by dampness such as wood rot. It also increases thermal efficiency, which enhance the lower level living experience. This type of design should be complemented with spray-in or blown-in insulation to prevent the formation of mold and mildew; just conditions could certainly compromise any resident’s health and well-being. This roofing system has the ability to convert an attic into a cozy living environment.
Considering a warm roof configuration can be the answer to the achievement of an energy-efficient house. It is the best option for new building projects since condensation is avoided and no additional ventilation is needed; this helps in the reduction of energy costs. Although more conventional structures are less expensive; the initial price to insulate a warm roof can be offset by the amount that will ultimately be saved in heating and cooling costs. Besides becoming familiar with the different layers of protection in this type of roofing structure, it is best to contact a professional contractor to discuss this idea in order to fully understand all of the pros and cons and the effect of various climates on it.
Achieving the layers of protection that a ‘warm roof’ offers is something that should be given careful consideration when it is time to construct a new or replace an old roof!
