Does Spray Foam Insulation Damage Roof Shingles?

No, spray polyurethane foam does not damage roof shingles or other roofing materials. This is because the foam expands outward as it adheres to the roof, and only when it begins to harden will it cling together.

In other words, there are no solid connections between the foam and the roofing material. It is also important to note that while foam boards, which require adhesives or nails to hold them solidly in place, can easily cause damage to tiles when improperly installed.

Spray foam insulation will not come in contact with the tiles at all and therefore, cannot cause any damage, even if installed improperly.

Can You Put Insulation Directly Against The Roof?

It is generally advised that builders not install fiberglass insulation directly against the underside of roof sheathing. There are a few reasons why experts usually advise builders not to install fiberglass insulation directly against the underside of roof sheathing.

The main reason for this is that fiberglass insulation is designed to trap heat, and if it is installed too close to the roof sheathing, it can cause the roof sheathing to overheat and potentially warp or damage the roof.

Additionally, fiberglass insulation can be difficult to install properly if it is too close to the roof sheathing. Getting the insulation to fit snugly against the roof can be difficult.

Another reason is that doing so can create a potential fire hazard. If the insulation is too close to the roof sheathing, it can prevent the heat from escaping, which can lead to the insulation catching fire.

Also, installing insulation directly against the roof sheathing can make it more difficult to ventilate the attic space properly. This can lead to moisture problems, which can lead to mold and mildew growth.

In addition, the insulation will be more likely to sag over time if installed directly against the roof sheathing.

Is Foil Roof Insulation Any Good?

Reflective foil insulation is an effective way to reduce heat loss and gain within a building envelope. Radiant heat transfer is responsible for over 70% of heat loss and gain, so reflective foil insulation can help keep a building comfortable in winter and summer.

This type of insulation works by reflecting radiant heat into the building, which helps reduce the amount of heat lost through the walls and roof. Foil insulation is also effective at reflecting sunlight, which can help to keep a building cooler in summer.

What Is The Best Insulation For A Conservatory Roof?

Thermotec Insulated Panels is a foil-backed, closed-cell rigid insulation system that provides exceptional thermal insulation for roofing applications. The closed cell structure helps to reduce the transfer of water vapor through the roof, which can lead to ice dams and leaks.

The foil backing prevents heat from transferring through the roof, helping to maintain a comfortable temperature inside the conservatory. The panels are also fire resistant, making them suitable for use in conservatories subjected to regular exposure to heat.
