Roof Insulation Improves Thermal Efficiency
If you’re in need of insulation, call us at Ohm Restoration today at 888-319-7058 for a free estimate!
Roof insulation helps to maintain a consistent temperature in your home. Without proper roof insulation, your heating and cooling system will work harder to regulate the indoor climate. The result will be substantial energy loss, a larger carbon footprint, and higher heating and cooling costs.
If you are unsure whether your roof insulation is functioning at its best, contact our roofing experts at Ohm Restoration to schedule an inspection.
What Are the Benefits of Roof Insulation?
Roof insulation provides a protective blanketing between the roof deck and the roofing surface. The benefits of roof insulation include:
- The added layer of protection from outdoor temperature, which helps maintain a consistently comfortable indoor environment
- More energy efficiency, so lower energy bills
- A consistent indoor temperature, which reduces roof deck expansion caused by extreme temperature fluctuations
- A natural resistance to fire and mold (with some types of insulation)
- An energy-efficient home, which produces a smaller carbon footprint
Reasons You Should Insulate Your Roof
In addition to higher utility bills, poor roof or attic insulation will affect other aspects of your life and comfort negatively in the following ways:
The temperature fluctuations in a home without good insulation are uncomfortable for everyone who lives under your roof.
- The inconsistent air temperature makes your HVAC system work harder than necessary, causing undue wear and tear.
- Inconsistent temperatures caused by faulty insulation can damage the structure of your home.
- Lack of roof insulation exposes your home to mold damage caused by rain or melting snow.
- Inadequate roof insulation degrades indoor air quality by allowing air pollutants and particulates to seep into the circulated air via cracks in your roof.
Choosing the Best Roof Insulation
Before starting the insulation installation, you need to know the R-value climate zone of your home. The term R-value refers to a system that measures and grades insulation based on its ability to prevent heat from leaving or entering a home.
Cooler climates have a higher R-value; they require a different type of insulation than warmer climates with a low R-value. The insulation with the higher R-value is the better performer.
Our team at Ohm Restoration can advise you on your R-value climate zone.
Other factors to consider when selecting the best roof insulation for your home include the type of roofing system and roof drainage you have, the building codes in your neighborhood, and of course, your budget.
During a roof inspection, our roofers at Ohm Restoration will assess the existing components of your roof and recommend the best roof insulation for your needs and budget.
Types of Insulation for Roofs
Your commercial building maintenance checklist should include routine roof inspections. Proper maintenance is essential to protect your roof from common problems and extend its working life.
At Ohm Restoration, we recommend that our customers schedule an inspection at least twice a year. Our contractors check for common roofing issues like gaps, holes, blisters, and clogged gutters during routine maintenance inspections. If we notice anything wrong with your roof, we’ll show you the problem and provide a professional roof repair service.
Scheduling an inspection at the beginning of spring and the end of fall helps ensure that your roof is ready for the upcoming temperature changes. One of the benefits of routine inspections is that they allow contractors to identify problems early and fix them before they become too severe.
Spray Foam Insulation
Polyurethane spray foam is a popular and effective means of insulating your roof. Spray foam insulation is ideal for sealing small cracks and leaks but equally effective when directly applied to the roof deck under the siding as full insulation. Spray foam is long-lasting and adheres to most surfaces, including wood, tile, and slate. This type of insulation is effective for climates with a high R-value.
Batt insulation is made of fiberglass and comes in rolls to be cut into shapes and sizes to fit rafters and ceiling joists. Batt blanket insulation is available in several R-values and sizes. Batt insulation is more affordable than spray foam but is less energy efficient and sometimes requires more than one layer for proper insulation.
Made from recycled materials, fiberglass, cellulose, or recycled materials, loose-fill or “blown-in” insulation is effective for insulating large spaces. The insulating material comes packed densely into bales and installed using a hose and blower. This type of insulation is suitable for insulating hard-to-reach areas when blown through a narrow tube.
Fiberglass loose-fill insulation is fire resistant but not suitable for cold climates. Conversely, cellulose is more durable than fiberglass and better suited for colder conditions but is flammable. Both types of insulation should be handled with caution, as loose-fill insulation fibers may contain toxic chemicals and air particulates.
Loose-fill and blown-in roof insulation give you the flexibility to control the amount of insulation your wish to apply to your roof decking based on the R-value of your climate. The disadvantage of this type of insulation is that it sometimes absorbs and retains moisture and sometimes deflates over time, requiring re-application.
