As energy costs go up and new roofs cost more and more, homeowners must consider making their homes more energy-efficient, and the roofs last longer. Adding more insulation and filling any places allowing heat to leak out of a building are important to home improvement projects. Too many homeowners just pay the heat bills and complain about how high they are but never make an attempt to make the home more air-tight and energy-efficient. But, the time and expense of this home improvement project will keep paying the homeowner back for years.

Why is Roofing Insulation so Important?

Roofing insulation is often ignored but it should not be. Roof insulation or lack of it affects a building’s performance and cost to heat and cool. Commercial buildings with flat roofs have rigid insulation attached to the steel or concrete deck. When a person is looking for a roofer in the St. Louis area, find one that is knowledgeable in all types of roofing and roofing insulation. Rigid insulation on flat roofs serves these functions:

* It acts as a thermal barrier

* it provides drainage

* It provides a working platform.

Roofing insulation’s thermal functions include:

1. Conduction is a type of heat transfer that can be controlled with adequate R-value insulation and eliminating thermal leaks in the total roof assembly.

2. Convection heat transfer can be controlled with an air barrier to reduce airflow, eliminating air gaps, and installing vapour retarders to reduce condensation. Gaps or high winds can create unwanted air movement in a roof system.

3. Radiation heat transfer can be controlled by using the appropriate roof surface for the climate and type of building.

Once the roofing and insulation systems are in place, storm damage can cause damage that should be repaired as soon as possible to avoid interior damage and new air leak problems that increase heating and cooling bills. You can check roof repair in Nassau County for more info. The same people who installed the roof and insulation often do repairs and can be called for emergency assistance.

Residential Roofing Calls For a Wide Selection of Roofing Materials

Residential buildings come with flat to highly pitched roofs and require different types of roofing choices. These choices can include slate roofing, concrete roofing tiles, metal roofing, clay roofing tiles, cedar shakes, and asphalt or composite roofing shingles. The roofer must be familiar with all of these roofing materials and be trained and experienced in properly installing them. Homes with flat or low pitched roofs will need special flat roof systems with built-in drainage.

Every home is unique and the homeowner will need good advice from the roofing company representative. Once the proper type of roofing is chosen and installed, the insulation issues should be considered. Why? Because the insulation between the roofing and the interior of the home can affect the roof’s performance and durability. The roofing company will ideally also provide the service of installing or adding to roofing insulation. If the roofer does not provide this service, a home renovation and insulation contractor can be hired.

Additional Things to Consider With Roofing Insulation

4. There are different types of roofing insulation solutions and the correct one must be used. Some of the products include blown-in insulation, spray foam insulation, batt insulation, and rigid insulation panels. Get expert advice from a builder, architect, structural engineer, or roofing company as to the best product for the home.

5. Check the condition of an existing roof for leaks and damage. Moisture coming from leaks will ruin the value of the insulation. Once the roof is repaired or replaced, the wet insulation must be removed and replaced. If the insulation is not adequate, heat rises from the interior and warms the roof. This can melt snow and form a liquid that can refreeze causing roof problems.

6. The attic must be sealed, filling cracks, holes, and gaps to prevent air transfer and water leaks. This can be accomplished with expanding foam or caulk. When all leaks are sealed the attic will need a proper ventilation system. Make sure the rim joists are also insulated. Check out small gaps around the chimney, plumbing stacks, electrical fixtures in ceilings, and more. Skylights should also be checked. Do not forget to check 2×4 top plates or framing that touches the underside of the roof.

7. Missing insulation can lead to mold problems that are dangerous for health reasons. Gaps in the insulation can attract warm air which moves up and hits cold air or surfaces and condenses into water that feeds mold on outside walls and ceilings, or in attics. This moisture can run down outside walls and cause stains on them and on ceilings.

8. When the attic and underside of the roof are being insulated, do not forget pipes. Condensation dripping from pipes can affect the insulation and other surfaces. There are foam pipe insulation stops that make this task easy.

Once the attic is properly insulated to protect the roofing and the inside of the home, do not forget maintenance. Attic venting is often located in a home’s soffits or along the roof ridge. They need to be cleaned out regularly so they do not become clogged and lead to poor ventilation. This can, in turn, lead to increased heating costs, mold and mildew development, ice dams, and reduction in the life of the roofing shingles. Vents can be cleaned with a leaf blower of with compressed air every few years or when the vents look clogged.

When a building owner is considering the type and amount of attic or roof insulation, they will need to achieve the correct R-value or the ability of insulation to resist heat transfer. In attics when insulation is added between ceiling joists with no attic floor, it is wise to install cover boards for roof access and people walking in the attic for other reasons.

The final purpose of roofing insulation is to keep cold air outside and warm air inside living areas. In addition, the warm air in the house or commercial building should not enter the attic and warm the underside of the roof. You can tell a building with inadequate insulation by how fast a new snowfall will melt. People who make the investment in adequate roofing insulation will have lower heating and cooling bills, a more comfortable interior space, and longer-lasting roofing materials.
