A properly insulated roof can bring greater home comfort and lower utility bills. Because the sun’s rays constantly heat the roof, it’s common for heat to get into the attic and the rest of the home. However, good Roofing Insulation In Dublin can prevent heat intrusion. Below are some utility and cost benefits of residential roof insulation.
Cool Roof Attributes
Most roofs are of a dark color; according to various sources, up to 90% of roofs are dark. Because a dark roof absorbs heat rather than deflecting it, it’s common for such a roof’s surface temperature to reach 190 degrees or more. By comparison, a cool roof can reflect heat and stay up to 70 degrees cooler during the summer cooling season.
Insulation Choices
Even if a homeowner isn’t considering replacing roofing materials, they can still get benefits by adding insulation to a current roof. When roofs are adequately insulated, they stop the sun’s rays and heat from seeping through and into the home. Below are some roof insulation options for residential buildings.
* Wood fibers: Fillers, wood particles and binding agents are combined to create insulating sheets. These typically have a coating that provides moisture resistance.
Perlite: Particles are combined with concrete to make a product that has serious insulating properties for residential roofs.
Polyisocyanurate: This foam-based option has a high R-value, which makes it a good choice in most climates.
Composite sheet insulation has several laminated layers for additional durability and strength in roofing applications.
Polyurethane foam is sprayed in a liquid form that solidifies as it dries.
Adding Insulation to an Existing Roof
When adding Roofing Insulation In Dublin, it’s necessary to add vents to the roof sheathing to create space between it and the insulation. The roofer will also add a moisture barrier before inserting the insulation without compressing it excessively.
Although adding an insulating layer under a current roof takes additional effort and it comes at an extra expense, the benefits are worthwhile in terms of increased eco-friendliness and savings.
