Ice Dams and Your Home

Posted on Fri, Jan 22, 2010 @ 10:19 AM

Whenever there is snow, you are likely to have troublesome ice dams to follow. Ice dams can cause major water damage and flooding to your home, which requires immediate attention.

As winter advances through cycles of freezing and thawing, buildings and homes experience ice buildup and roof damage. In general, ice dams are formed when attic heat moves up to warm the roof and melts snow at or near the ridge. Snow melts, runs downward and hits the edge of the cold roof, resulting in re-freezing snow.  These cycles cause ice to accumulate and back up under shingles. Damage appears in the form of soaked insulation, stained, cracked and damaged sheet rock, damp, smelly, rotting wall cavities and stained, blistered and peeling paint.

Preventing Ice Dams
To prevent an ice dam, don't heat the roof, keep it cold. That way, the snow on the roof eventually dissipates without making large amounts of meltwater. The underside of the roof deck should not exceed 30 F. The best way to maintain low temperatures is by ensuring that there is adequate insulation and sealing gaps that let warm air pass into the attic from the house. The attic must also be ventilated, so that cold air is introduced into it and heated air escapes rapidly.  InsulationIncreased insulation in an attic will help to prevent ice dams. First, insulate the areas between the roof rafters. It is important to keep an air space between the roof deck and the insulation in order to prevent a condensation buildup that can delaminate the roof deck. Prior to insulating, install polystyrene rafter air channels, which are available at home centers.  If there's a hatchway into the attic, build a cover for it out of rigid poly-styrene insulation.

If the gable and ridge vents do not generate sufficient air movement to dissipate the heat, you will need a motorized vent at one end of the attic to exhaust the heat, and an adequately sized vent on the opposite end of the attic to draw in cold air from the outside.

Ice Dam Inspection
Check your home carefully when ice dams form. Investigate even when there doesn't appear to be a leak. Look at the underside of the roof sheathing and roof trim to make sure they haven't gotten wet. Check the insulation for dampness. And when leaks inside your home develop, be prepared. Water penetration often follows pathways difficult follow.  Don't just patch the roof leak. Make sure that the roof sheathing hasn't rotted or that other less obvious problems in your ceiling or walls haven't developed. Detail a comprehensive plan to fix the damage and more importantly, solve the problem.

The best way to maintain low temperatures is by ensuring that there is adequate insulation and sealing gaps that let warm air pass into the attic from the house. The attic must also be ventilated, so that cold air is introduced into it and heated air escapes rapidly. Some remodeling contractors are under the impression that heat passing through the attic helps prevent ice dams, when just the opposite is true. Although excess heat moving from the attic through the roof rapidly melts snow, once the meltwater touches the cold eaves, it quickly freezes and forms an ice dam.

If you have a furnace in the attic, it may not be possible to prevent ice dams. Increased insulation, however, should help. First, insulate the areas between the roof rafters. It is important to keep an air space between the roof deck and the insulation in order to prevent a condensation buildup that can delaminate the roof deck. Prior to insulating, install polystyrene rafter air channels, which are available at home centers. Next, lay insulation blankets over the furnace's heating ducts to help reduce the heat buildup in the attic. If there's a hatchway into the attic, build a cover for it out of rigid poly-styrene insulation.

If the gable and ridge vents do not generate sufficient air movement to dissipate the heat, you will need a motorized vent at one end of the attic to exhaust the heat, and an adequately sized vent on the opposite end of the attic to draw in cold air from the outside.

It's Cold Out...Stay Warm & Be Safe!

Posted on Wed, Jan 14, 2009 @ 04:58 PM

Arctic air is expected to hit the New York Metro area by tomorrow, and is expected to last until Sunday. Many Homeowners will be using various heating sources to stay warm, including electric heaters and fireplaces. Fire safety is essential to your family and should be discussed with all members of your household.

Heating equipment is among the leading causes of home fires nationally and in New York State. Very often heating related fires are the result of a lack of maintenance or simple acts of carelessness. Following the guidelines below will help to ensure that you reduce the possibility of experiencing a heating related fire.

Fire tips from NY State's Office of Fire Prevention and Control include:

Fire Prevention
To prevent fires, keep furnishings and other combustibles 36 inches from all heating sources. A heating source too close to combustibles is the leading cause of fires due to home heating. Store matches and other fire starting appliances out of the reach of children. Fires started by children often have tragic results.

Follow Proper Maintenance
Proper maintenance and an annual inspection of heat pumps, furnaces, space heaters, wood and coal stoves, fireplaces, chimneys and chimney connections by qualified specialists can prevent fires and save lives. Follow the manufacturer’s instructions for installation, venting, fueling, maintenance and repair.

Review the owner's manual to make sure you remember the operating and safety features.

  • Space Heaters – When using portable heaters, do not place them where it is possible for small children or pets to fall against them or to receive a contact burn. Avoid the use of extension cords with electric heaters. Always turn off space heaters before leaving the room or going to bed.
  • Fuel Burning Appliances – When taking a heater out of storage in the fall, install batteries and inspect the shut off mechanism and wick for proper operation. Fill the tank with fresh fuel. Let the heater cool down before refueling. Adding fuel to a hot heater can start a dangerous fire.
  • Wood Burning Appliances and Fireplaces – Do not burn trash in the wood stove or fireplace. Burn only well-seasoned hardwoods. Be sure the fire you build fits your fireplace or stove, don’t overload it. Be sure wood stoves are installed at least 36 inches away from the wall. Keep combustible materials well away from the fireplace, stove and chimney. Keep the area around them clean. Always use a fireplace screen to prevent sparks from leaving the fireplace and starting a fire. Never leave a fire unattended.
  • Chimneys - Creosote accumulation is the leading cause of chimney fires. A chimney that is dirty, blocked or is in disrepair can inhibit proper venting of smoke up the flue and can also cause a chimney fire. Nearly all residential fires originating in the chimney are preventable. An annual chimney inspection by a qualified chimney sweep can prevent fire or carbon monoxide poisoning.
  • Ashes – Keep wood stoves and fireplaces free of excess ash buildup. Excessive ash buildup prevents good circulation of air needed for combustion. When removing ashes, use a metal container with a tight-fitting cover. Always place ashes in an outside location away from structures. Ashes that seem cool may contain a smoldering charcoal that can start a fire.

Frozen Pipes in Your Home!

Posted on Fri, Nov 21, 2008 @ 12:38 PM

Although Winter officially begins on December 21st, the New York Metro area has already posted FREEZE WARNINGS during overnight conditions.

Homeowners in need to start thinking about the possibility of pipes freezing in their homes and how to prevent property damage, including water damage to a structure.

Preventing Frozen Pipes
Before the onset of cold weather, prevent freezing of water supply lines and pipes by following these recommendations:

Outdoor
Drain water from swimming pool and water sprinkler supply lines following manufacturer's or installer's directions. Do not put antifreeze in these lines unless directed. Antifreeze is environmentally harmful, and is dangerous to humans, pets, wildlife, and landscaping.

Remove, drain, and store hoses used outdoors. Close inside valves supplying outdoor hose bibs. Open the outside hose bibs to allow water to drain. Keep the outside valve open so that any water remaining in the pipe can expand without causing the pipe to break.

Water Supply Source
Check around the home for other areas where water supply lines are located and are in unheated areas. Look in the basement, crawl space, attic, garage, and under kitchen and bathroom cabinets. Both hot and cold water pipes in these areas should be insulated. A hot water supply line can freeze just as a cold water supply line can freeze if the water is not running through the pipe and the water temperature in the pipe is cold.

Insulation
Consider installing specific products made to insulate water pipes like a "pipe sleeve" or installing UL-listed "heat tape," "heat cable," or similar materials on exposed water pipes. Many products are available at your local building supplies retailer. Pipes should be carefully wrapped, with ends butted tightly and joints wrapped with tape. Follow manufacturer's recommendations for installing and using these products.
