The winter this year has been mild but that does not mean we have seen the last of winter. Your heating costs are beginning to climb. Thankfully, there are methods to stay warm without investing a small fortune or packing up and moving to a sunnier climate. House insulation is the key to lower winter season energy expenses, keeping heated air in the house and cold air out. (It helps your house stay more comfortable in summertime, also.) And among the major locations where you wish to restrict heat transfer is your roof. Here are ways to insulate the roof so your family stays warm and cozy while your energy expenses stay under control.
Gainesville GA Roof Maintenance
The first step is basic and inexpensive … simply the way we like it: Work with what you have. Keep your roof in excellent shape through routine examination and timely repair work. Fix loose, curling, or cracked roofing shingles and take care of any rotted wood or gaps in the roofing system fascia, soffit, and flashing right away. This type of preventive medicine will safeguard the inside of your house against icy drafts as well as water leakages.
“Cold” vs “Warm” Roof Space
Next, you’ll need to decide between a “cold” and a “warm” roofing system area. These terms refer to precisely where the roofing insulation will be set up (at joist level or adjacent to the rafters respectively), not to the resulting temperature in your home. In fact, a cold roofing system area is a good idea if you reside in a part of the country that has extreme winters. It is much less likely for a hot roof to cause fallen snow to melt and refreeze, forming hazardous ice dams. It’s likewise simpler and cheaper to retrofit with insulation; nevertheless, warm roofing does permit a greater level of heat retention.
Blanket insulation is one of the most common approaches to insulating a cold roofing area and is typically produced from fiberglass. Your roofing contractor will install a vapor barrier as required. He will then carefully present the blanket insulation on top of the barrier, ensuring that it is flush with the roof joists and getting rid of any spaces in between lengths of insulation. Have your professional cut an opening in the blanket for the electrical elements to avoid their getting too hot.
Recycled or sheep’s wool insulation provides a more environmentally friendly option to conventional fiberglass. The previous is usually made out of post-consumer cellulose recycled from old newspapers or from cotton mill scraps or recycled fabric (which is where it gets its label, “blue jean insulation”), while the latter is made from natural sheep’s wool.
Spray Foam Insulation
Spray foam might be utilized to insulate both hot and cold roofing systems. Have your roofing contractor check that your roofing remains in good condition before attempting this kind of treatment and make sure to coat all rafters or trusses thoroughly with the foam, to prevent heat transfer by means of the wood.
The most common variation of the treatment includes spraying on a type of plastic, typically either polyurethane or polyisocyanurate, in the form of a foam which will solidify into a stiff thermal insulation barrier. The foam is ecologically bothersome, however, because of it off-gases VOCs for 24-28 hours after being sprayed on. Throughout this time, homeowners of your house will have to find alternative lodgings up until the fumes have dissipated. Issues have likewise been raised about prospective risks to health when the foam is eventually eliminated.
As a green option, cellulose insulation is offered in spray-on kind. It was actually a disadvantage compared with the plastic-based sprays, nevertheless– namely that it is a less effective insulator. The technology for producing environmentally more secure, effective roof insulation sprays is still in the works.
