Your radiant barrier makes the roof deck sheathing invisible from the attic.
Radiant barrier roof life.
Lowering the temperatures above living space ceilings provides a significant benefit by reducing air conditioning loads and energy usage.
This may seem unbelievable since radiant barriers are sold on the fact that they will reflect 97 of radiant energy away from their surface.
The temperature of the attic space increases and that heat is transferred to the building below.
Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.
Radiant barriers are utilized to reduce summer heat gain in attics.
This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.
A radiant barrier works best when it is perpendicular to the radiant energy striking it.
But on the bright side.
Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction.
The short answer is no damage will occur.
Installing a radiant barrier underneath the roof will cause the roof temperature to increase by a few degrees usually 2 10º.
Tests have shown that installing a radiant barrier in attics generally only cause the roof and shingles to increase about 2 10 fahrenheit.
Benefits of radiant barrier roof underlayment when you add a radiant material to your roof or attic you will help your home retain its conditioned air during both hot and cold seasons.
Roofs with radiant barrier have the potential to lower the temp at night because the radiant barrier prevented the heat loss that would typically occur from the traditional mass insulation on the attic floor rising to heat the roof.

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.
Radiantguard radiant barriers reflect block 95 97 of the radiant heat transfer and when installed in an attic space they can result in a reduction of attic temperature below the radiant barrier of up to 30 degrees.
This means radiant barrier can increase the life of the roof shingles.
Increasing summer energy consumption and cooling costs.
