The Importance of Due Dilegence for a Happy Home Purchase

home inspection services and due diligence
Due diligence will make you happy when purchasing a home!

I get asked all the time, “should I get the well checked out, should I get the septic inspected, should I get a camera inspection of the sewer pipe out to the street, what about the water, radon test, water test, asbestos?” Yes, Yes, Yes and yes and yes!  For most people the home is one of the biggest investments you will have.  Due diligence is essential to ensure your investment is sound and healthy.  Steps can be taken now to fix any issues. The seller can be asked to fix any problems or take money off the selling price.  Extra testing beyond the home inspection will cost more money and take longer to complete.  If you have to spend $1000.00 in testing and inspections this is nothing compared with the value of your home, your health and the value of your peace of mind.  In most cases you can just roll these extra expenses into your loan.  Anyway you look at it if there is any doubt about a system in the home you are about to purchase by all means get it checked out by a professional.  The home inspector will most likely only offer radon, and water testing.  The other tests will have to be conducted by other parties.  If you are buying an older home they will likely need more inspections.  Work with your realtor and set a realistic closing date so you can get all the inspections and tests done.  One test that may take a long time to get done is the septic inspection.  Depending on the time of year it may be weeks before a septic company is available to pump out the septic and perform their camera inspection.  Also, well companies may take a while to come and test flow rates and the well system. For maximum long term return on your investment, your heath and piece of mind, if in doubt get it checked out!

Asphalt Shingle Roof Defects

Roof defects are often a surprise to home owners.  It is an area of the home that is seldom thought of or looked at unless there is a problem.  Roofs in Montana are put to the test with high wind, extreme cold, extreme heat, dryness, harsh sun hail and rain. It is the intense sun and dryness that really take its toll. UV damage and drying out of the tars that hold the asphalt shingle together are major factors in premature shingle failure. The following are examples that I have found of common defects.

Here is a shingle roof from 1977.  It is 40 years old.  This one is a no brainier and was no surprise to anyone that it is bad.  It probably needed replaced about 20 years ago.  The roof now leaks in several places and water is showing itself on the interior ceiling.  These pics give you an idea of what happens to a roof if not replaced when it should be. These shingles are simply worn out with missing shingle stones, missing shingles, cracking, and curling.

The next picture is one you don’t see to often.  In this picture the framing or sheathing is pushing up the shingles.  This roof was relatively new but this area will likely age quicker as the shingles are under stress along this line.

The next picture may be hard to see but that is exactly why it catches owners off guard.  Excessive shingle stone loss and where on the edges of the shingle.  At this point the shingle will age rapidly as the fiberglass fibers and asphalt are being exposed to the elements.  The shingle is becoming thinner and more brittle.

Shingle stone loss

The following pictures show what happen when shinlges have been abraded.  In this case this roof is in a high snow area where the roofs are periodically shoveled off.  The impact of snow removal tools creates spots that where and degrade quickly.  This roof also suffers from excessive shingle stone loss.

Missing shingle tabs are another defect that can go unnoticed esecially on a high roof that is hard to see from the ground.  This creats a direct path for water entry  into the home as the roof barrier has been disturbed. The following are pictures of  missing shingles.

The following picture is something we don’t see very often in Montana.  Algal growth on a roof can happen here when the right conditions exist.  In this case this was a north facing wall with a west facing roof slope butting up to it. It was also shaded from a west facing wall.  There were many tall trees around the house as well.  Moss or plant growth can damage siding and roofing by getting behind the protective layers and drawing moisture into these spaces.  The can also physically lift and push, breaking the shingles.

Some roof defects are easier to see from the attic!  The roof may appear ok from above.  The following are a couple of examples of roofs with issues seen from underneath.  The fist example was a roof truss that had experienced continual wetting and had severe rot and mold as a result.  The flashing on the roof was not sufficient to keep the water out because of a poor design on the roof.  The second example is actually a metal roof where the screws were misplaced, causing water to leak into the attic around the screws.

Having a roof inspection is a vital part of a home inspection.  It is also important for any home owner to conduct one periodically to ensure the roof integrity and make necessarily repairs and replacements.  In this way the longevity of the roof can be ensured. Call today for a home inspection

1. Definitions and Scope

1.1.  A general home inspection is a non-invasive, visual examination of the accessible areas of a residential property (as delineated below), performed for a fee, which is designed to identify defects within specific systems and components defined by these Standards that are both observed and deemed material by the inspector.  The scope of work may be modified by the Client and Inspector prior to the inspection process.

  1. The general home inspection is based on the observations made on the date of the inspection, and not a prediction of future conditions.
  2. The general home inspection will not reveal every issue that exists or ever could exist, but only those material defects observed on the date of the inspection.

1.2.  A material defect is a specific issue with a system or component of a residential property that may have a significant, adverse impact on the value of the property, or that poses an unreasonable risk to people.  The fact that a system or component is near, at, or beyond the end of its normal, useful life is not, in itself, a material defect.

Home Inspections in Bozeman, Montana

Home Inspection in Bozeman will look at the home as a system
The Home System

Bozeman , Montana has become a very desirable place to live.  With a recent population growth in the Gallatin Valley of 3.6 percent the county ranks 24th  in growth across the nation.

Houses are being built at breakneck rate all over the valley.  There is a wide variety of housing stock available from turn of the century shacks to brand new Mansions with the paint still wet (literally).  There is a sort of frenzy in the air with buying, selling and building.  Navigating this frenzied environment can be a daunting task for everyone involved.  Buyers, Sellers, Builders, Real Esate Professional, Tradesman, everyone with a hand in the pot is busy.

If you are a buyer having a general idea of the housing stock in Bozeman can help you focus your search.  In general the central area from about Ace Hardware and radiating out for about one to two miles contain the older homes.  These are the homes that typically have the most defects, differed maintenance issues and code issues. In many cases they also have unconventional construction and materials.  Many of them may have very shallow foundations or no foundation at all. They present unique and interesting questions for home inspectors because they have to be assessed for what they are in the context and time in which they were built.  There may be many health and safety issues that must be assessed and reported.  If you head further out from the center the housing stock becomes a mix of old and new.  South of town there are many moderately old neighborhoods from the 60’s through the 80’s. West of Ferguson you will find many new neighborhoods, most of which are still being built up.  Newer homes will be less likely to have very much differed maintenance and in general will have very few code issues. However the quality of construction and over site varies widely and there can be many important issues with these homes that need to be addressed.

Choosing a home in the older part of Bozeman will have its advantages for walk-ability, bike-ability and a general feeling of being at the heart of it all. But these homes will come with there own set of unique and sometimes insurmountable issues.  Being out a bit in a more planned neighborhood will provide quieter neighborhoods with more open space.  These homes will be away from the pulse and action but will have less issues.  Whatever your preference having a home inspection performed will help you make a wise choice for you and your family.

The importance of water testing

Water is something that is easy to take for granted, especially here in Montana.  We have access to clear clean water, basically coming from its source in the mountains.  The cities treat water and most wells have acceptable water if not very good with excellent natural minerals. But all is not always well.  Old pipes can leach out heavy metals and ground water can become contaminated with nitrogen and bacteria. Some common contaminants that have been encountered in and around the gallatin valley are Chloride, Flouride, Sulfate, Iron, Nitrate/Nitrite and Bacteria/Ecoli. Other factors to test for are Coductivity and pH. Bozeman is next door to one of the largest calderas in the world, Yellowstone.  The area is rich in volcanic rock and minerals.  The Madison River which flows out of Yellowstone National Park is naturally contaminated with arsenic.  The water in the Three Forks area can have high levels of arsenic.  We all must drink water and it is convenient to be able to drink the water in our own home.  All of the above contaminants can be dealt with using the proper treatments.  The first step in treatment is testing so that proper treatments are utilized.  Most home sales involving a well will have a water test performed testing for Nitrates/Nitrites and Bacteria/Ecoli.  High levels of nitrogen are a sign of contamination from fertilizer.  The presence of Ecoli can be a sign of ground water contamination from neighboring septic or from animal feces. The presence of bacteria can mean the same thing as Ecoli or can just mean the water system is dirty and in need of cleaning.  Heavy metal testing should be performed if the house is old with original water pipes.  Lead and copper are the 2 most common contaminants originating from old plumbing. Call today for a discussion of your water testing needs.

Thermal Imaging and Log Cabins

Air leakage where wall meets log beam

Thermal Imaging can be very useful for log cabins.  Homes constructed with logs have numerous places for air to potentially leak from the home.  When air leakage is bad enough uncomfortable drafts develop and heat bills are high.  All the joints between logs and any change in direction of the wall have joints that need sealed.  Also the logs themselves can develop cracks (checks). Caulking and chinking dry up and logs change shape so a log home that was originally well sealed can become leaky.  With thousands of feet of potential leaky cracks sealing every joint can be an expensive and time consuming process.

Infrared imaging
Air leaks where framed wall meets logs

With thermal imaging the worst air leaks can be identified and dealt with.  Resealing every joint between every log may not be necessary.  Maybe only the corners and areas around doors and windows will need sealed.  Sometimes the air leaks have been present since the home was built and the log joints themselves are just fine.  Often times stick framed areas such as dormers and gable ends leak air where they meet the logs.  Also when tongue and groove wood is used over framed walls or ceilings there can be numerous air leaks at knot holes and board joints.

ir000233
Air leakage where ceiling meets logs

Thermal imaging is a good way to reveal air leakage when combined with the blower door.  The blower door creates a negative pressure in the home which draws air in through the leaky cracks.  This will accentuate the areas where air is leaking to provide a more precise map for pinpointing areas of the home needing sealed.  Also the blower door will quantify the air leakage.  A goal can then be set for how much sealing needs done and how much energy savings can be obtained with the money needed to achieve the air sealing goal. A before and after  blower door reading can be recorded and the exact savings calculated after air sealing is conducted.

Thermal imaging is an excellent way to find air leakage in any home but becomes especially important in log home construction where thousands of feet of potential air leaks exist. Call today to talk more about thermal imaging and your home.

 

The Roof Inspection

The integrity of the  framing and the roofing surface are vital to the health of a structure.

During the  inspection the attic is accessed to view the underside of the roof and the framing that supports it.  Any defects are noted in the report.

Damaged attic vent

Defects include broken or sagging framing, loose fasteners, damaged plywood, wet wood or water stains from leaks, mold, rusty metal, etc. The surface is also walked on or viewed from the edge of the roof to inspect for surface defects and wear.  Defects include excessive wear, holes, dents, missing components, improper roofing materials, rusty or missing flashing, dried or missing sealants, etc.  Another aspect of the roof that requires assessment is the ventilation.  If there is not enough ventilation the roof will trap heat in the summer.  This heat can damage the roofing surface and/or the support structure.  Also poor ventilation can result in high humidity in the winter with condensation and mold development.  The inspection will let you know how your roof system is performing so you can plan for the future either by making repairs now or having some time before anything needs to be done.

Many types of roofing exist and all of them have there own unique strengths and weaknesses.  They all fail in different ways.  With knowledge of how these different roofing systems are put together we can better inspect the particular system that is encountered.

Tools that may be utilized to inspect are a thermal camera, moisture meter, probe, or hammer and flashlight.  The most important tools are simply the eyes, hands, head and feet of the inspector. Experience and knowledge will lead the inspector on the correct path to discovering defects.  While walking on a roof the deck under the roofing material can be accessed for strength by gently bouncing on the areas between rafters.  The framing members will be probed and “wiggled”, the eyes will always be searching. In this way the inspection will provide the home owner or buyer vital information about the home. Call today for your home inspection

The importance of thermal imaging on flat roofs

406-599-8790

I was reminded the other day of the importance of infrared imaging and flat roofs. The roof in this picture developed leaks even though it looked to be in fair condition. Infrared imaging showed that it was taking on water throughout. If infrared imaging had been conducted earlier and the roof problems addressed water damage in the building could have been avoided.

thermal imaging inspection
thermal image of flat roof

Commercial or residential buildings with flat roofs are especially prone to leaking.  Ice damning, snow load, ponding water, and Montana sun all profoundly affect a flat roof system.  Especially when the roof is older and the structure is not well insulated the ice buildup can be quite intense.  Because of the ice and snow buildup owners usually have to shovel the snow and ice off the roof.  Over time this damages the roof surface with abrasions. Also water will sit on a flat roof at low spots.  When water sits it has a chance to penetrate the roof membrane at any weak points.  With many bright sunny days in Montana we experience a lot of sun related damage to all roof systems.  Flat roofs are not exempt from this damage.

There are several types of flat roof systems and they are often hard to identify.  On older roofs there could be several generations of roofing material.  Older roofs used hot tar and felt.  Newer roofs are composed of a various membrane membrane materials or a “rubber” applied as a liquid.

Whichever type of flat roof system you have a Infrared Imaging inspection can help identify areas of concern.  These areas can then be addressed before water can penetrate and damage the structure.

Air tightness testing

 

406-599-8790

Air tightness testing with blower door and duct blaster.

Are you a builder in need of air tightness testing to satisfy the local building department?  We are certified to perform these tests with the Building Performance Institute (BPI) We are also listed with the Bozeman, MT building department: blower door certified. You will receive a written report that can be give to the building department.  We will perform a total leakage test on the house using the blower door and a total duct leakage test using the duct blaster.

Options:

Call today to discuss your project.  Whether you are new to performance testing or are an experienced pro we will come up with a plan for your project.

Blower door testing for home air tightness.

Some builders are already adept at creating tight housing.  In that case I recommend doing a final test after the house is completely done.  Other builders may need a little help getting the house properly sealed. In that case I recommend doing some testing before finish materials are in place.

The air leaks will be dealt with before finish materials are installed so the final test will be low enough to pass.

Duct Blaster Testing for forced air system air tightness.

Ducting that is installed in unheated space like attics will need to be tested.  The entire system has to be tested at once not just the areas in the unheated space. The duct test should be conducted after the entire duct system is roughed in and the air handler is in place.

duct air tightness testing
Duct Blaster

This will ensure access to all the ducting for further sealing if needed.  All the supply and return registers will be sealed off and the test fan installed in a return register.  The system will be depressurized and leakage calculated. A smoke machine can also be used to find leaks during the test, especially if the HVAC contractor is having trouble creating a tight  system. Call today:
