Polyurethane foam is a common material used to insulate roofs. You might also use spray foam when the polyurethane foam becomes damaged and needs to be replaced. However, when adding all of this foam to insulate your roof, you might wonder if your roof needs to be able to breathe. This isn't necessarily correct.
The Hot Roof Problem
A problem that sometimes occurs with a roof is the "hot roof" situation. This is where moisture enters your attic and is not able to escape. As a result, your roof might start to rot and develop other problems.
However, depending on how the foam roofing system is installed, moisture might not be able to get inside the roof in the first place. You will need to have your roof sealed so that there are no cracks or crevices that allow moisture to enter through.
Why You Should Seal Off Your Roof
Sealing off a roof can be a better idea than creating a ventilation system because differences in temperature between the attic and the rest of the home can lead to condensation. Condensation could lead to mold growing in the attic.
How to Add Foam Insulation
When you are having insulation added to your roof for the first time, you will want to hire a professional foam roofing system installation service. You will need the foam to be installed, and you'll also need to have professional roofers make sure that there are no openings that can allow moisture to enter.
Spray Foam Can Replace Damaged Insulation
When the foam insulation has become damaged, such as if you had a leak in your roof that needed to be repaired, you will need the damaged portion of the insulation to be removed. Spray foam insulation can replace the damaged insulation.
How Professionals Add Foam Insulation
The high-density foam is sprayed inside the roof with a fan-shaped tip. The spray foam is used to fill the area. Because the foam is sprayed into the roof, it will fill in gaps that other methods of insulation might miss. You might be able to fully seal off your roof from the outside.
Spray foam is great for roofing insulation because it will not damage your shingles and is very easy to use. Therefore, if you are installing a new roof or replacing an existing roof, it's a good idea to contact a foam roofing system installation service.
