Termite Inspection Standards for 2020

Termite Inspection Standards for 2020

Understanding the New Rules

Does it seem like Termite Inspections,  also called wood destroying insect inspections (WDI),  are yielding more recommendations for treatment these days? You are probably right. It’s not that there are more termite you need a termite inspection because termites work day and night to eat you out of house and homeinfestations. It’s more likely the result of the 2020 rules changes. What changes? Read on.

On January 1, 2020, a new standard for the termite inspection and wood destroying insect inspections took effect and the changes are significant. In July 2019, the National Pest Management Association (NPMA) released an updated and revised NPMA-33 Wood Destroying Insect Inspection Form. That’s the standardized form that all pest inspectors use for real estate WDI inspections. According to NPMA, all previous editions are now obsolete. That means for real estate transactions, only the current form bearing a revision date of 7/1/2019 should be accepted.

There are a few revisions you need to know about. There are changes in language such as the replacement of the word “defects” with “wood destroying insect damage.” More significantly, the section on page one of the report noting evidence of previous treatment has been eliminated and the page two guidelines regarding when to recommend treatment for termites has changed.

Pest inspectors have always recommended treatment whenever live termites are observed. The new standard says “if no evidence of a previous treatment is documented and evidence of an infestation is found, even if no live termites are observed, treatment or corrective action by a licensed pest control company should be recommended.” The new guidelines call for documentation of treatment, not just evidence like drill holes.

In the past, if a termite inspector found shelter tubes or other evidence of infestation without observing live termites and also found evidence of prior treatment, they generally didn’t recommend treatment in their report. Under the new standards, unless there is documentation of prior treatment, termite inspectors are recommending the property be treated.

Home sellers who have had their homes treated for termites in the past are advised to have the documentation of treatment at the ready. Be advised that the new guidelines also give the pest inspector latitude to recommend treatment if documentation is too old or in some other way inadequate.

Heavy rain and flooding can negatively impact a home’s termite protection system. The NPMA has published a technical update explaining what you need to know. Get it here

Your roof keeps you and your family safe

Roof Coverings: Balancing Aesthetics with Performance

does your roof look like one of these
is this your roof

How is your roof? According to the Federal Emergency Management Agency (FEMA), during storms, your roof does a lot to protect your home. Besides keeping you and your family safe from rain, lightning, sleet, hail, and windblown debris, it keeps the inside of your home dry and can even act as a structural diaphragm in certain situations, keeping your home from falling down around you. In order to protect the home, your roof must resist both high and low temperature extremes, rain, high winds, exposure to ultraviolet radiation, snow, ice formation, and hail.

Of all the hazards your roof faces, wind is the most problematic according to FEMA. Living in the Midwest, you already know extreme weather with high winds or tornadoes can devastate a home. Even an average Midwestern thunderstorm can wreak havoc on a home’s roof. When wind force is greater than the roof system can handle, it can be disastrous. Wind can tear roof coverings from roof decks. It can separate roof decks from framing. And roof punctures from windblown debris can seriously impact the roof’s integrity.

Repeated exposure to wind events can wear down a roof’s first line of defense, the roof covering. Choosing the right roof covering for your home can make a big difference in how it weathers the storm. Homeowners have a lot to consider when balancing style and budget with performance.

 

Three Popular Options for Flat Roofs

 

Built Up Roofing (BUR): Hot-mopped built-up roofing (BUR) is one of the oldest types of roof coverings for flat roofs. They’re installed using several layers of roofing felt impregnated with asphalt and hot mopped with a low-grade crude oil called bitumen.

Hot-applied coal tar pitch blends with the bitumen-soaked felt creating a fused roof membrane generally two to four layers thick. Finely crushed stone granules may be applied to the top layer of tar to give the roof additional protection from the elements. A BUR roof is relatively in expensive. If well maintained, it can last 20 to 30 years.

 

Torch Down Roofing: Sometimes called “torch on” roofing, it requires an open-flame propane torch for installation. Torch down roofing is the most common type of roofing used on flat or very slightly pitched roofs. It’s a two- or three-layer roofing product consisting of a tough membrane of bitumen modified with rubber or plastic and embedded in a thick layer of asphalt. Torch down roofing can tolerate changing temperatures well and expands and contracts without melting or cracking. It’s usually a little more expensive than BUR roofing, but it also tends to be more resistant to punctures and UV rays.

 

 

Membrane Roofing (Rubber Roofing): Single layer membrane roofing is the most popular for commercial buildings, but it’s being used in residential roofing too. EPDM (ethylene propylene diene monomer) rubber roofing is perhaps the most synthetic rubber is the most common single-ply membrane roof material in both residential and commercial use. It’s also one of the more durable option for homes with flat roofs. Installed as thin sheets and being made of rubber or polymer, they’re flexible, elastic, and can handle temperature changes better than built up roofs (BURs). It also costs a little more with a similar lifespan.

 

Several Popular Options for Pitched Roofs

 

Asphalt Shingles: Widely considered the best choice for most homes. They are relatively light, inexpensive, and easy to install. Sheets of roofing are layered to give the illusion of more expensive single shingles, like cedar or slate, that are installed one shingle at a time. This means the asphalt shingles take less time to install. An asphalt shingle roof typically has a lifespan of 12 to 30 years.

 

Metal Roofing: Metal roof covers are an Eco-friendly choice that’s highly recyclable and energy efficient. It’s also wind and fire resistant. The most common type of metal roof is the standing seam roof. It’s made up of aluminum or steel roofing panels with interlocking raised seams. Installation is generally faster than most other roof covering types. For those who want the longevity and fire resistance of metal, but don’t like the look of standing seam roofs, metal shingles fill the bill. These steel or aluminum shingles or shakes can mimic asphalt, wood, or slate shingles, or even clay tiles. Metal roofs can last 30-50 years or more, but typically cost four to five times as much as asphalt shingles.

 

Clay Tile: This is a traditional choice that offers an exceptional aesthetic appeal. They can be left as unglazed red clay tiles or glazed and fired to become ceramic roofing tiles. Clay tiles have been used to cover roofs for centuries. They’re particularly good at resisting salt and heat damage, making them a popular choice in desert and coastal areas. They are a rather expensive choice, costing as much as $30 per square foot. But since a properly maintained clay tile roof can last more than a century, they are a one-and-done solution.

 

Concrete Tile: If you love clay tile but just can’t bring yourself to pay the price, concrete tile presents a similar looking, but less expensive option. Unlike clay, concrete tiles can be dyed to taste. Because it is molded, concrete tiles can be shaped to mimic rolled clay tiles or low-profile roofing like wood shakes. Concrete tile is a very heavy roofing material, making it a good choice in high-wind regions. It’s also fire resistant, last up to 50 years and is little as half the price of clay tiles.

 

Wood Shake and shingles: Wood shingles are precision sawed, thin slabs used to cover the roof. Wood shakes are hand-cut, making them thicker and more durable than machine-made wood shingles. Wood is a good insulator, and hand-cut shake shingles can last up to 40 years in a relatively dry climate with proper maintenance. But wood is not very fire resistant and moisture can shorten the lifespan of a wood roof considerably. They are one of the more expensive options, but also considered one of the most attractive roof covers on the market today.

 

Slate: Very popular for historic buildings, slate roofing is very long-lasting and durable. Slate shingles are thin sheets of real stone. This traditional choice combines beauty with enhanced protection, making it one of the most desired roof coverings available. It’s pricier than most other options, costing double or triple the price of even clay tiles. A slate roof represents a compromise between cost and near-permanence since slate roofs have been known to last centuries.

 

Synthetic Slate: Love the look of slate shingles, but not the price? Enter synthetic slate shingles, also called rubber slate. These engineered shingles look surprisingly similar to natural slate from the ground. Made from engineered polymers and recycled plastic and rubber, synthetic slate is a lightweight alternative that makes it an option for houses that can’t support natural slate’s the heavy weight. The rubber slate shingles are not as durable as slate but can last 50 years or more. They’re also priced closer to the cost of wood shake or metal shingles, making them much more affordable than real stone.

 

With all the roof covering choices available to homeowners, there really is something just right for everyone. Just as each type brings a unique style and benefit to the task, it also brings its own shortcomings and wear issues.

 

A Certified Roof Inspector is well versed in the positives and negatives of each roof covering type. They have the specialized training to properly gage the condition of the roof covering, spot installation issues, weather damage, and wear issues that could compromise your roof’s integrity. Since the roof covering is your roof’s first line of defense against the elements, it’s important that your home inspector has the expertise needed to properly inspect the roof. Protect your investment. Insist on a certified roof inspector.

Aluminum Wiring in Older Homes

Does Your House Have Aluminum Wiring

Aluminum wiring was used from 1965 until 1972 in some homes in our area due to a severe shortage of copper.  Originally considered a safe and economical substitute for copper wire, aluminum was used throughout the country.  The aluminum wire used at the time soon developed problems. Its use was discontinued in residential branch wiring for 15 and 20 amp circuits in 1972. Continue reading “Aluminum Wiring in Older Homes”

Double Lugged or Tapped Connections

Double Lugged or Tapped Wires

Double lugged or double tapped breakers are one of the most common electrical defects we find during a standard home inspection.  Double lugging is defined as two or more wires installed in a breaker that is only rated for one wire.  There are two instances where this commonly occurs; 1. On standard 120 or 240 volt breakers and 2. Less often on the main breaker. Continue reading “Double Lugged or Tapped Connections”

Why Test for Radon

Radon is the second leading cause of lung cancer exceeded only by smoking.  Like smoking Radon is a long term threat with variables such as the radon level present and the length of time you were exposed.

According to the United States Environmental Agency 21,000 people die of lung cancer from Radon gas exposure each year.  That number does not include those who go through the pain and suffering of lung cancer and do not die.This is more than die from choking, drowning, firearm homicides, carbon monoxide and second hand smoke combined (20,758).

Knob and Tube Wiring problems

Knob and tube wiring

If your house was built before 1950 there is a good chance it will contain Knob and Tube  (K&T) wiring.  Knob and tube wiring  was used from the 1880’s until the late 1940’s.  K & T wiring was almost always installed by a professional electrician.

K & T wiring was considered very efficient and safe.  However as electrical demands increased, knob and tube wiring was phased out and replaced with modern products. Continue reading “Knob and Tube Wiring problems”

S-Traps vs P-Traps

S-traps are no longer allowed in new construction

Years ago most plumbing codes banned S-trap configurations in favor of P-trap style fixtures. S-traps are no longer used in modern plumbing because on rare occasions with just the right conditions the water can be sucked out of the trap allowing sewer gas to enter your home.

The risk from sewer gas can be much worse than just that terrible smell. Sewer gases can be poisonous or even explosive and are not to be treated lightly. Continue reading “S-Traps vs P-Traps”

Plumbing problems found at inspections

Plumbing  Problems are Often Easy to Repair

Plumbing repairs called out in a home inspection are usually minor.  However occasionally we find problems that must be repaired.  These are usually do-it-yourself projects gone terribly wrong.

Many plumbing repair problems can easily be addressed by a handy man or a proficient do-it-your-selfer.  Other problems such as a replacing a sewer main should only be addressed by a licensed plumber. Continue reading “Plumbing problems found at inspections”
