This house has a beveled cedar siding system, often sold as, "tight knot," cedar. This is a quality wood siding product. Where exposed to direct sunlight, such as on south and west faces, this siding can dry out and suffer from cupping and splitting. Regular staining on the sun-exposed sides of the building can slow this process. It is typical to need to do more maintenance such as staining and caulking at sun-exposed faces of the building. Refrain from nailing cupping siding down as this can split the siding.

Roof flashings are used to keep a roofing system waterproof where the roofing material starts, stops, changes direction or is penetrated. During inspection, we look for standard flashing techniques that could be considered normal or standard in our region. Damaged, incomplete or non-standard flashings can be a sign of an older or less reliable roofing system and may require repair. Any non-standard flashings noted during inspection will be reported on below if found.

Metal roofing: The life expectancy of metal roofing materials can vary from 20–50 years, depending on the method of manufacture, thickness, of the roofing material, the quality of the installation, and the roof design and exposure. Maintenance for metal roofs is often dictated by the manufacturer and recommended maintenance procedures can vary depending on whether the roof material is painted, has zinc all the way through, or whether it is thinner sheet metal with painted-on weather protection. Some roofs only require debris to be cleaned off to prevent water damming. Others have proprietary cleaning methods to prevent damage to coatings and may require touch-up of corrosion to prevent corrosion from causing leaks.

I tested the voltage at the electric panel today. It tested in a normal range of 235-245 volts. Most residential construction is listed as 120/240 volts. Slight fluctuation is normal.

During a home or property inspection, every effort is made to inspect the visible components of the electrical system grounding. The grounding system is critical for safely discharging electrical surges, especially in the case of lightning strikes. There is no way in the context of a home inspection to verify the "effectiveness" of the grounding system as much of the system is not visible and there are not practical tests one can perform in the way we can test a furnace or a plumbing fixture. However, there are many things that can lead me to recommend further evaluation of the grounding system by a licensed electrical contractor and they will be documented in the observations below if discovered.

During the inspection, I attempt to visually document electrical system bonding. There is no way in the context of a home inspection to verify the "effectiveness" of system bonding. All metallic systems in the building are required to be "bonded" (connected) to the the building's electrical grounding system. Bonding creates a pathway to shunt static charges (that would otherwise build up on the system) to earth, and to provide a pathway to trip a breaker in the event that these bonded metallic components became energized. There are many things that can lead me to recommend further evaluation of this system by a licensed electrical contractor and they will be documented as repair items in the observations below if discovered.

During inspection I make an effort to test and inspect all accessible electric receptacles and switches. In general, the scope of testing is directly related to access; where personal belonging and furniture obstruct access to receptacles and fixtures, fewer of them can be reasonably tested during inspection. All defects found during inspection today will be listed in this report.

The installation of carbon monoxide alarms is recommended for all homes that have fuel burning appliances such as gas or oil furnaces, gas water heaters, gas ovens and cook-tops, gas fireplaces and wood stoves. In addition, Washington State law (WAC 51-51-0315) now requires UL 2034 approved carbon monoxide alarms in ALL homes and condominiums being sold in Washington State. The location should be: at least one alarm outside of all sleeping areas and one on each floor of the house. Best practices are to have these alarms hardwired with a battery back-up - though requirements are for the installation to meet manufacturer's specifications. Carbon monoxide is a colorless, odorless gas that can cause sickness, nausea and even death. Alarms have a useful service life of roughly 6 years, so changing them more frequently than smoke alarms is recommended.

This photo shows the most recent service records found on the heating equipment during inspection.

The heating and cooling system has disposable air filters installed. These should be changed quarterly or more to ensure proper air flow at the furnace. Be sure to install the filters with the arrows pointing in the same direction as the air flow in the furnace.

This shows the water pressure tested during inspection. Generally, "normal water pressure," should be between 30-80 PSI, though pressures near or below 30 can result in poor functional flow to fixtures. Water pressures in excess of 80 PSI risk damaging supply piping components and should be controlled with a pressure reducing valve.

The visible portions of the supply piping appear to be insulated. However, prior to freezing weather it is always a good idea to check pipes and hose bibs for adequate insulation and freeze protection to protect pipes from cold weather and freezing conditions. Hose bibs can often be winterized prior to cold weather.

Copper water supply pipes were installed. Copper pipes installed prior to the late 1980's may be joined with solder that contains lead, which is a known health hazard especially for children. Laws were passed in 1985 prohibiting the use of lead in solder, but prior to that solder normally contained approximately 50% lead. Note that testing for toxic materials such as lead, is beyond the scope of this inspection. Consider having a qualified lab test for lead, and if necessary take steps to reduce or remove lead from the water supply. Various solutions include:

• Flush water taps or faucets. Do not drink water that has been sitting in the plumbing lines for more than 6 hours
• Install appropriate filters at points of use
• Use only cold water for cooking and drinking, as hot water dissolves lead more quickly than cold water
• Treat well water to make it less corrosive
• Have a qualified plumber replace supply pipes and/or plumbing components as necessary

A temperature and pressure relief valve (TPRV) is required on all water heaters to discharge any excessive pressure within the tank. A discharge pipe should be attached to the valve and directed to a safe location away from body contact. Newer installations must be directed to the building exterior or to an approved indoor drain receptor. Most manufacturers suggest that homeowners test these valves at least once a year by lifting the lever to ensure the valve discharges properly and also recommend inspection of these safety devices every three years. The picture here shows a typical TPRV. They may also be found on the side of the heater on some models. I do not test these valves due to the possibility that they may leak after testing. A leaking or inoperative TPRV should be replaced immediately by a licensed plumber.

Due to inconsistencies between both UPC and IPC Plumbing codes, and water heater manufacturer's instructions, and TPRV manufacturer instructions, it is not actually possible to install the drain from the Water Heater TPRV "properly." There are conflicts with distance of termination to the floor/ground, types of pipes approved, and diameters of pipes approved. Additional confusion is added when jurisdictional inspectors approve installations/materials specifically not allowed by both codes and manufacturers. My recommendations will vary depending on the installation and will be included in the applicable narratives below.

Most codes defer to manufacturer instructions and I favor those recommendations. The yellow tag on the valve states clearly the termination should be 6" above the floor which is more consistent with the UPC code requirements.

Proper dryer exhaust venting is critical for safe and reliable performance from the dryer. Here are some basic rules of thumb for dryer exhaust duct installation: Unless a vent-free appliance is being used, the dryer exhaust vent must terminate outdoors. It should be no more than 25 feet long and for every 90 degree turn subtract 5 feet and for every 45 degree bend subtract 2.5 feet. Use only smooth-wall metal vent pipe @ 4 inch pipe diameter. Do not use plastic pipe and plastic flex pipe. If a flexible connector is needed behind the dryer use a short amount of corrugated metal pipe. If the exhaust duct is getting pinched behind dryer, consider use of a dryer vent box, pictured here. Flex and corrugated pipes should never be used in concealed spaces such as through walls or in attic or crawl spaces. Insulate dryer exhaust duct where it passes through unconditioned spaces to prevent condensation that could hasten lint build-up inside the pipe. Do not use screws to connect pipe as these can trap lint. Secure duct with foil tape as needed. Be sure duct is sleeved properly so that it will not trap lint and clean the vent regularly, especially if it is a long exhaust run.

Attic and roof cavity ventilation is a frequently misunderstood element of residential construction. All roof cavities are required to have ventilation. The general default standard is 1 to 150 of the attic area and ideally, this comes from at least 60% lower roof cavity ventilation and 40% upper, but this is a wild over-simplifications of the subject. As a good guiding principle the most important elements for healthy attic spaces, which are traditionally insulated and ventilated are:

1. Make sure the ceiling between the living space and the attic is airtight
2. Ventilate consistently across the whole lower part of the roof cavity with low, intake soffit venting
3. Upper roof cavity venting is less important and if over-installed can exacerbate air migration into the attic from the living space.
4. Avoid power ventilators which can depressurize the attic and exacerbate air migration from the house into the attic.

During inspection of the crawl space, every effort is made to inspect the entire space. Visual inspection of crawl spaces is difficult and limited as access is often restricted by pipes, ducts and sub-floor insulation as well as limited clearances.

Signs of seismic protection noted during inspection. This inspection is not a cohesive analysis of seismic engineering, but I do look for signs of seismic protection.
