    What’s a Building Envelope Consultant

    Have you heard the term “Building Envelope Consultant”? It is used to describe staff like ours that have expanded beyond roofs and into the exterior building envelope. This expansion of services is the result of an under served market and extensive new building performance & code requirements. In 2017  Carl A. Hargrove, AIA published a great article in  Facility Executive Magazine Online that explains in great detail when to utilize and what to expect from a Building Envelope Consultant. The following is an exert from his article.

     

    “With today’s strict energy conservation codes and increasingly complex facade and roof systems, many new construction projects involve the services of a building envelope design professional. This also applies to expansions and adaptive reuse. Making the best use of that consultant’s services is important not only to the bottom line of the project, but to the energy efficiency, code compliance, sustainability, integrity, and longevity of the building. When should a building envelope consultant get involved?  What services should he or she be expected to provide?  How does the consultant’s role differ from that of the architect of record? What, exactly, does a building envelope consultant do?” Click here to read the entire article.

     

    I hope you find this informative and helpful. Contact me to discuss how we can assist with your exterior building envelope assessments, troubleshooting, design of repair/refurbishment scopes, testing, etc.

    Simple Advice for Budgeting

    Like you, our workload changes with the seasons. As winter arrives our focus begins to transition from performing roof inspections & other fieldwork to designing roof replacements for the upcoming year. Early during this process we often see that a budget is secured, but the amount is incorrect.  This is often the result of reused budgets that do not take into account the individuality and specifics of each building.

     

    We are currently designing projects that range in cost from $3.50 / sf to $38.00 / sf.  There is a reason for this spread.  Of the available 250,000+ roof component options, only a few may actually be suitable for your particular building.   Project costs will vary based on building type, local code requirements, contractor selection, roof type, etc. All these factors must be accounted for when designing and budgeting the new roof assembly. Not all systems are created equal and each system has its strengths and weaknesses.  There is no “perfect” system for all applications.

     

    No one wants to go “back to the well” to request additional funding after a budget has been established.  Because of this we recommend preparing specific budgets for each project.  In the case that an insufficient budget has been set, it is recommended to delay the project until appropriate funding can be allocated versus “value engineering” the roof design. As always, we are here to help if you have any questions or want to discuss your 2017 budgets.

    2016 LTTR Values

    In January 2014 we sent a newsletter discussing newly posted  LTTR values (R-value) resulting from revised testing criteria. According to the National Roofing Contractors Association (NRCA) the R value of 1″ of polyisocyanurate insulation has dropped once again effective January 2016.
    Why the change?
    This is the result of applying the newest test methods to insulation boards of varying temperatures.  Apparently boards at colder temperatures provide higher R values than boards at warmer temperatures. NRCA has chosen to refer to the lowest common denominator when listing new R values.  Below is a breakdown of changes by year.
    2013: 1″ of polyisocyanurate = R6
    2014 & 2015: 1″ of polyisocyanurate = R5.7
    2016: 1″ of polyisocyanurate = R5.0
     
    How does this effect you? 
    Most local building codes require an insulation package meeting R20 whenever a new roof system is installed. In 2014 & 2015 only 3.5″ of polyisocyanurate insulation was required to satisfy the R20 requirement.  In 2016, 4″ of polyisocyanurate insulation will be required to meet the R20 requirement. Additionally, the new roof height will be reducing flashings heights by 1/2″.  This may result in additional work required to meet industry standard 8″ minimum flashing heights. Ultimately these factors will result in more material & associated costs for future roof replacements.

    We hope you find this information helpful.  Contact us to discuss how this may effect your future projects.

    Now Offering Electronic Leak Detection (ELD)

    RoofTech Consulting has recently introduced Electronic Leak Detection (ELD) to our list of services.
    Electronic leak detection (ELD) is often referred to as Electronic Field Vector Mapping (EFVM). There are two methods of ELD, low-voltage and high-voltage. These testing methods utilize electrical current to test the integrity of roofing and waterproofing membranes.  Our electronic leak detection equipment will assist in locating pinholes, leaks, and areas of weakness in non-conductive roofing membranes.  This type of testing is critical prior to project closeout or prior to the installation of overburden, pavers, etc.  This testing method often replaces traditional flood testing due to ELDs level of accuracy and speed of completion.


     

      

    Low Voltage Electronic Leak Detection: Enables testing on wet (water present) waterproofing and roofing membranes.

     

     

     

     

     

     

     

     

    High Voltage Electronic Leak Detection: Enables testing on dry (no water present) waterproofing and roofing membranes.

     

     

     

     

     

    Developing roof management programs, performing roof inspections, and designing reroofs are still our main focus but we are excited to offer a full lineup of complimentary services to meet our clients’ needs. Please contact me to schedule a demo of this testing method or to learn more about what we do.  We look forward to hearing from you.

    Winter 2012

    Greetings!

    Thanks for taking the time to check out our newsletter!  We understand that your time is valuable so this newsletter will only contact the most pertinent information related to your roofs.  We would like to know what topics or issues you would like us to cover in the future.  Contact us with your ideas.  Enjoy!

    It’s finally here!

    After a very dry summer we are beginning to see more precipitation.  With this rain come lower temperatures and eventually the freeze/thaw cycle.  This cycle of freezing and thawing can cause minor issues to rapidly worsen.  Regardless if you own your building or manage the facilities of others, now is the time to take advantage of this dry, warmer weather and schedule your winter roof evaluations.

    It may be as simple as removing rooftop debris, applying a few patches, or clearing roof drains.  A roof evaluation performed now will cost only a portion of what emergency repairs may cost once ice and snow have accumulated.  Rooftop issues that are found and corrected now will save you the cost and inconvenience of bigger issues.

    What we do…..

    In response to a growing need in the roofing industry , RoofTech Consulting Inc. was chartered in June of 2001.  RoofTech is an authentic “third party” independent roof consulting firm in compliance with the Code of Ethical Practice ratified by the Roof Consultants Institute.  RoofTech provides a full range of roof consulting, testing, roof planning, and roof management services to facility managers and Professional Consulting, Architectural, and Engineering firms.
    We specialize in infrared moisture scans, annual roof evaluations, preparing reroof project specifications, and reroof project management.

    Map Showing Areas of Significant Hail on 4/7/15

    It’s Spring in the Midwest and the rain & hail have arrived!  Fortunately for most areas, the hail received today measures less than 1/4″ in diameter and is not large enough to result in substantial damage.  However, some areas received much larger hail (1.75″+) that likely resulted in damage to cars, homes, buildings, etc.  These areas are identified in red on the map below.  We are providing you this map to use a reference to verify if you may have experienced substantial hail.  Hopefully you receive this information before unreliable vendors, consultants, and contractors waste your time focusing on areas of non-damaging and insignificant hail activity.
    Proper assessment and documentation is vital when filing a storm damage claim with your insurance carrier.  If  believe you may have experienced hail large enough to result in damage, contact us to review the site and properly document the “pre-repair” conditions.  Any recommended repairs should be completed by your preferred Roofing Contractor after the conditions have been properly documented.  For best results, the insurance claim should be worked by the combination of your Roof Consultant and Roofing Contractor.  Keep in mind that not all damage may be immediately apparent to the untrained eye.

    Cold Weather Related Roof Damage Explanation

    With the recent colder weather you are likely experiencing an increase in roof leaks.  We would like to offer a brief explanation for this recent uptick in roof issues.
    After a very mild winter we are now receiving extremely low temperatures, ice, and an increase in  precipitation.  These weather changes result in a more active freeze/thaw cycle.  Freezing and thawing results in the expansion and contraction of exposed roof components.  The colder the weather, the more potential for extreme contraction.  This continued and extreme movement can ultimately lead to cracks, splits, and seam failure.  Each roof system will react differently to movement based on roof design, roof type, and roof age.  Unmaintained and aging roofs will commonly experience the most severe damage.  Repairs may be as simple as applying a few patches, overlaying seams, or clearing roof drains.  In some cases this continued movement can result in systemic failure, ultimately requiring roof replacement.

     

    It is our recommendation to continue to make leak repairs immediately once a leak is identified.  Some leaks may return or become ongoing based on the remaining winter weather.  Once weather permits, a formal roof inspection is recommended to further investigate the condition of your roof.  We recommend that your roof inspection be completed by a firm accredited by the Roof Consultants Institute (RCI).  RCI professional members adhere to a strict ethics code that offers unprejudiced service without affiliation with any product or manufacturer.  Utilizing a firm affiliated with the RCI ensures that you receive the best possible information to help you make the most informed decision.  More importantly, the inspector is not interested in the revenue generated from completing roof repairs or replacement.
    We hope you find this information helpful.  Contact us if you have any questions, if you would like to schedule spring roof inspections, or to discuss other technical services that we offer.

    New Services for 2015

    RoofTech Consulting has recently introduced two new services to our portfolio.  Both of these services can provide savings by ensuring that your facility and it’s building components are properly performing. Let me take a moment to share a very brief overview of both services.

     

    The first service we have introduced is thermography of the exterior building envelope. Infrared technology has rapidly become one of the most efficient methods of investigating thermal performance of vertical walls. Our certified thermographer utilizes noninvasive infrared technology to scan the exterior building envelope for air leakage or other deficiencies. This information can be referenced when making repairs to ensure that repair efforts are focused at the correct locations. A thermograpahic scan can also be utilized post repair to ensure that the work was properly completed and has corrected the appropriate issues.
    The second service we have introduced is the testing of moisture content within newly poured concrete floors/decks. Identifying the relative humidity within newly poured concrete will assist with knowing when new flooring or roofing can be installed. Without adequate testing the contractor accepts the liability associated with installing their products over uncured concrete. This trapped moisture can create blisters, sweating, premature failure, or worse. We follow the guidelines and reporting methods set forth in ASTM F2170 to ensure quality control and adequate testing quantities.

     

    Developing roof management programs, performing roof inspections, and reroof design are still our main focus but we want to make sure that we offer a full lineup of complimentary services to meet our clients’ needs. Please contact us to learn more about these or other services offered by our firm.

    Infrared Thermography of the Exterior Building Envelope

    The extreme weather conditions that we experience in the Midwest can be taxing on buildings. For more than 4 months out of the year severe thunderstorms, heavy rains, and hot and humid temperatures are the norm. At the opposite end of the spectrum we experience high accumulations of snow and severely cold temperatures in the winter. This combination of extreme conditions can reveal a buildings true vulnerability to water intrusion and air leakage. Correcting these vulnerabilities is becoming a priority for maintenance personnel and others responsible for building care. Many are realizing the benefits of infrared technology to provide condition assessments of their facilities. With infrared inspections you can reduce these expenses by identifying what components and/or systems really need to be replaced or repaired.

     

    In addition to our infrared roof moisture scanning, RoofTech Consulting, Inc. is now providing building envelope infrared inspections. We now have a Certified Level I Thermographer on staff that will allow us to thoroughly evaluate the performance of your building and its integrity. Commercial building scans using infrared technology allow us to see what is really going on with a buildings performance and efficiency. Infrared Building Envelope Performance Surveys provides information on:

    • Trapped moisture in the walls of the building
    • Moisture intrusion
    • Insulation deficiencies
    • Air infiltration at windows and perimeter detailing
    • Air exfiltration at windows and perimeter detailing

    Thermal imaging survey data can now help you detect these problems along with other deficiencies before they become serious and costly issues. If you are a property owner or facilities manager, infrared testing adds an invaluable dimension to you building diagnostics and preventative maintenance program.

    The thermographic image on the left shows a west-facing exterior building wall. The arrows indicate localized areas of air displacement at windows and roof-to-wall transitions. The digital light image on the right was taken at the same moment and shows what is seen with the naked eye.

     

    Please contact myself or our Certified Infrared Thermographer with any questions you may have regarding this, or any of our other services.

    Workshop for the Installation of Air & Vapor Barriers

    Winter if fast approaching those of us that live in the Midwest. With the changing weather comes new seasonal issues for the construction industry. Specifically, exterior components such as waterproofing of building walls and roofs. Colder weather changes how construction materials react, perform, and how they should be installed. These seasonal effects in addition to recent code changes, are resulting in a stronger focus for monitoring the installation of waterproofing components. As a result we are seeing an increase in firms performing quality assurance inspections during the installation of these components. Corrective action for improperly installed components is much less intrusive and far less expensive if completed before the installation of cladding or backfilling of dirt.

     

    As a result of this initiative and the recent code changes The St. Louis Building Enclosure Council is offering a workshop next week. The details and registration flyer is below for your review. Register yourself or forward to anyone that might benefit from this event.

    In addition to assisting with roofing, our firm can also help with performing quality assurance of air & vapor barriers. Don’t hesitate to contact us if you have any questions or concerns about your next project.
