Ever wonder about your house number? Often, the previous owner installed the number and the new owner never had to think about it, leaving them clueless as to why it was placed where it is or why a particular color or size was chosen. These numbers are more important than you probably realize, and a lot of thought goes into making sure they are visible.
Consider the following recommendations:
- The numbers should be large, within reason. Try to make them at least 5 or 6 inches tall. Smaller numbers may not be visible from the street if you have a large front yard. Replacement house numbers can be purchased from hardware stores and online.
- The numbers should be of a color that contrasts with their background. Reflective numbers are great because they are easier to see at night. Brown on black or white on yellow may look swanky but are bad choices for the purpose.
- Try not to put house numbers behind any trees, shrubs, or anything else that may obscure their view from the street.
- Make sure that the number faces the street that is listed in the house’s address. It does emergency workers no good if the house number faces a different street than the one the workers are traveling on.
- Is your house not visible from the road? Then the number should be placed at the driveway’s entrance.
- The next time you hire an InterNACHI inspector, ask him whether your numbers are adequate. Inspectors should know the laws in your area and be able to offer you a professional opinion.
Keep in mind that you may need to make adjustments.
Even if your house number is currently adequate, InterNACHI believes that it might need adjustment in the future. The following are common reasons why you may need to adjust your number in the future:
- The addresses assigned to houses by the city occasionally change, and you must adjust your numbers accordingly.
- The trees or shrubs in front of your house have grown so much that the number is no longer visible.
- House numbers installed in the winter may be visible during that season, but become blocked by budding vegetation by spring or summer.
Maintain your house numbers, along with the rest of your home’s exterior.
- Keep your numbers clean. They may not be reflective or contrasting if they are covered in mud.
- Trim back vegetation as needed.
- Don’t let piles of snow obscure the numbers. If this happens, raise the number so this situation does not happen again.
Winterization is the process of preparing a home for the harsh conditions of winter. It is usually performed in the fall before snow and excessive cold have arrived. Winterization protects against damage due to bursting water pipes, and from heat loss due to openings in the building envelope. Inspectors should know how winterization works and be able to pass this information on to their clients
Water damage caused by bursting pipes during cold weather can be devastating. A ruptured pipe will release water and not stop until someone shuts off the water. If no one is home to do this, an enormous quantity of water can flood a house and cause thousands of dollars’ worth of damage. Even during very small ruptures or ruptures that are stopped quickly, water leakage can result in mold and property damage. Broken water pipes can be costly to repair.
- All exposed water pipes in cold areas, such as attics, garages, and crawlspaces, should be insulated. Foam or fiberglass insulation can be purchased at most hardware stores. Insulation should cover the entirety of a pipe.
- Plastic is more tolerant of cold expansion than copper or steel. Houses in colder climates might benefit from the exclusive use of approved plastic plumbing.
- Water supply for exterior pipes should be shut off from inside the house and then drained.
- Sprinkler systems are particularly vulnerable to cracking due to cold-weather expansion. In addition to turning them, it helps to purge the system of any remaining water with compressed air.
- Homeowners should be aware that much of the plumbing system travels through areas that are significantly colder than the rest of the house. Because it is impossible to monitor the temperature of every portion of the plumbing system, indoor air temperature should be kept high enough throughout the winter to keep pipes in any unheated places from freezing.
Leaks in the Building Envelope
- Windows that leak will allow cold air into the home. Feeling for drafts with a hand or watching for horizontal smoke from an incense stick are a few easy ways to inspect for leaks. They can be repaired with tape or caulk.
- On a breezy day, a homeowner can walk through the house and find far more leaks than they knew existed. Leaks are most likely in areas where a seam exists between two or more building materials.
- Because hot air rises into the attic, a disproportionately larger amount of heat is lost there than in other parts of the house. Like a winter hat that keeps a head warm, adequate attic insulation will prevent warm indoor air from escaping. Attic insulation should be 12 inches thick in cold climates.
- Storm doors and windows should be installed to insulate the house and protect against bad weather.
- Test the furnace by raising the temperature on the thermostat. If it does not respond to the adjustment quickly it might be broken.
- Replace the air filter if it’s dirty.
- If the furnace is equipped with an oil or propane tank, the tank should be full.
- Use a hose to remove leaves and other debris from the outdoor condensing unit, if the home is equipped with one. Protect the unit with a breathable waterproof cover to prevent rusting and freezing of its components.
- Remove and store window air conditioners when they are no longer needed. Cold air can damage their components and enter the house through openings between the air conditioner and the windowpane.
- Ceiling fans can be reversed in order to warm air trapped beneath the ceiling to recirculate. A fan has been reversed if it spins clockwise.
- The chimney should be inspected for nesting animals trying to escape the cold. Squirrels and raccoons have been known to enter chimneys for this reason.
- The damper should open and close with ease. Smoke should rise up the chimney when the damper is open. If it doesn’t, this means that there is an obstruction in the chimney that must be cleared before the fireplace can be used.
- A chimney-cleaning service professional should clean the chimney if it has not been cleaned for several years.
- The damper should be closed when the fireplace is not in use. An open damper might not be as obvious to the homeowner as an open window, but it can allow a significant amount of warm air to escape.
- Glass doors can be installed in fireplaces and wood stoves to provide an extra layer of insulation.
- If debris is left in gutters, it can get wet and freeze, permitting the formation of ice dams that prevent water from draining. This added weight has the potential to cause damage to gutters. Also, trapped water in the gutter can enter the house and lead to the growth of mold. For these reasons, leaves, pine needles, and all other debris must be cleared from gutters. This can be done by hand or with a hose.
- Missing shingles should be replaced.
- Patio furniture should be covered.
- If there is a deck, it might need an extra coat of sealer.
- Winterize toilets by emptying them completely. Antifreeze can be poured into toilets and other plumbing fixtures.
- Winterize faucets by opening them and leaving them open.
- Water tanks and pumps need to be drained completely.
- Drain all water from indoor and outdoor plumbing.
- Unplug all non-essential electrical appliances, especially the refrigerator. If no electrical appliances are needed, electricity can be shut off at the main breaker.
Ice dams are problematic because they force water to leak from the roof into the building envelope. This may lead to:
- rotted roof decking, exterior and interior walls, and framing;
- respiratory illnesses (allergies, asthma, etc.) caused by mold growth;
- reduced effectiveness of insulation. Wet insulation doesn’t work well, and chronically wet insulation will not decompress even when it dries. Without working insulation, even more heat will escape to the roof where more snow will melt, causing more ice dams which, in turn, will lead to leaks; and
- peeling paint. Water from the leak will infiltrate wall cavities and cause paint to peel and blister. This may happen long after the ice dam has melted and thus not appear directly related to the ice dam.
- Keep the entire roof cold. This can be accomplished by implementing the following measures:
- Install a metal roof. Ice formations may occur on metal roofs, but the design of the roof will not allow the melting water to penetrate the roof’s surface. Also,snow and ice are more likely to slide off of a smooth, metal surface than asphalt shingles.
- Seal all air leaks in the attic floor, such as those surrounding wire and plumbing penetrations, attic hatches, and ceiling light fixtures leading to the attic from the living space below.
- Increase the thickness of insulation on the attic floor, ductwork, and chimneys that pass through the attic.
- Move or elevate exhaust systems that terminate just above the roof, where they are likely to melt snow.
- A minimum of 3″ air space is recommended between the top of insulation and roof sheathing in sloped ceilings.
- Remove snow from the roof. This can be accomplished safely using a roof rake from the ground. Be careful not to harm roofing materials or to dislodge dangerous icicles.
- Create channels in the ice by hosing it with warm water. Because this process intentionally adds water to the roof, this should be done only in emergencies where a great deal of water is already flowing through the roof, and when temperatures are warm enough that the hose water can drain before it freezes.
Prevention and Removal Methods to Avoid
- electric heat cables. These rarely work, they require effort to install, they use electricity, and they can make shingles brittle.
- manual removal of the ice dam using shovels, hammers, ice picks, rakes, or whatever destructive items can be found in the shed. The roof can be easily damaged by these efforts, as can the homeowner, when they slip off of the icy roof.
