Know your roof system!

National Roof has been educating clients about metal roof system: attributes, performance, maintainability and sustainability for more than 50 years. National Roof uses available, fact based evidence to bring about resolution to simple as well as complex roof system conditions and problems. National Roof endeavors to differentiate between symptomatic and casual relationships as they pertain to moisture infiltration. Causality is often a non roof related function with respect to building water breaches. Not only has this data been observed by National Roof technicians and staff over many decades, but it has been substantiated by numerous studies.

Because not all building roof leaks are as they appear to be, and other factors may be acting to generate or facilitate moisture encroachment within or into the building envelope, it sometimes makes sense to evaluate peripheral material component details as well as atmospheric conditions that may have a hand in vapor transport.

Analytical tools and monitoring equipment compliment the National Roof knowledge-base in assisting building owners by identifying and often pre-empting; serious water breaches, insidious moisture migration problems, premature roof component failure, and unscheduled capital replacement expenditures.

Building owners and managers have businesses to run and may not be equipped or do not have the time to tend to roof system responsibilities and best practices that are paramount to roof system longevity and are required by manufacturers to preserve warranty coverage. This is where a good, outside professional organization can assist in establishing a roof audit & preventive maintenance program that is cost effective, minimizes moisture infiltration issues and frees the owner to concentrate on business operations.

  • Metal Roof System Audits – Routine or annual metal roof system audits keep the building owner fully informed on important facts, and minimize the unexpected. Read More
  • Building Envelope pressure differential & Internal Atmospheric assessment – Inside air quality not only impacts employee productivity &well being but also the health of the building structure and envelope. Pressure differentials can create serious moisture migration issues that adversely impact building and roof component integrity. Read More
  • Condensation critique – Condensation is often mistaken for a leaking roof. Read More
  • Construction detail evaluation –It is extremely important to have proper roof system component configurations that yield long term water-tight assemblies. Read More
  • Energy losses through roof insulation systems – Entrapped moisture within roof insulating systems not only accelerates roof panel & component deterioration but undermines building envelope conservation efforts through energy loss. Read more
  • Cool Roofing considerations - [ look before you leap] - Cool white roofing requires a more than a rubber stamp of approval. You might be surprised by some of the research findings. Read Article
