In a triple net lease, the tenant pays the landlord rent, property taxes, fire insurance, and the tenant’s share of
maintenance expenses for the property. The cost for future property taxes and fire insurance can be reasonably
estimated, But estimating and budgeting for future
roof maintenance costs can be difficult without a professional
roof condition assessment.

A flat roof lasts longer if it is properly maintained. Unless a old tar and gravel roof has been neglected for too long
and there are many problems in many areas, a built up roof of tar, paper and gravel will last 20–30 years. There
are built-up roof systems in place dating to the early 1900s.

Typical flat roof maintenance includes getting rid of ponding water, typically within 48 hours. This is accomplished
by adding roof drains or scuppers for a pond at an edge or automatic siphons for ponds in the center of roofs. An
automatic siphon can be created with an inverted ring shaped sprinkler, a garden hose, a wet/dry vacuum, a check
valve installed in the vacuum, and a digital timer. The timer runs two or three times a day for a minute or two to start
water in the hose. The timer then turns off the vacuum, but the weight of water in the hose continues the siphon
and soon opens the check valve in the vacuum. The best time to address the issue of ponding water is during the
design phase of a new roofing project when sufficient falls can be designed-in to take standing water away. The
quicker the water is got off the roof, the less chance there is for a roof leak to occur.

Periodically, a formal moisture survey should be done in addition to the normal roof condition assessment. There
are three major types of moisture survey systems used, none of which actually measures water. All of them
measure properties of the roof materials that change when there is water present.
  •   An infrared scan measures the amount of heat retained or lost through the insulation. Wet insulation
    transmits heat better than dry materials. Thus, the infrared camera will pick up the higher levels of heat
    radiated by wet materials. Inverted system and loose laid ballasted single ply membranes cannot be infrared
    scanned successfully.
  •   Nuclear isotopic meters work by sending hydrogen ions into the roof system and counting the number that
    bounce back. Because water has two hydrogen ions in every molecule, the number of ions counted
    increases significantly when water is present in the roof.
  •   Electrical capacitance and resistance meters measure the ability of roof materials to conduct electricity.
    They work on the principle that wet materials conduct electricity better than dry ones do.

Each of these testing methods has limitations. The roof condition assessment experts should determine their
applicability to a particular roof before they are used. It is worthwhile to have a formal moisture survey done at least
once every five years.

All roofs should be assessed semi-annually and after major storms. During the winter the cold, storms and
precipitation contributes to the demise of the roof. During the summer the solar UV radiation is higher, and the roof
is subjected to high heat and to thermal shock due to sudden cooling during summer rains. Particular attention
should be paid to the flashings around all of the roof top penetrations. The sharp bends at such places can open
up and need to be sealed with plastic cement, mesh and a small mason's trowel. Additionally, repairs to lap seams
in base flashings should be made. 90% of all roof leaks and failure occur at the flashings. Another important
maintenance item, often neglected, is to simply keep the roof drains free of debris. A clogged roof drain will cause
water to pond, leading to increased "dead load" weight on building that may not be engineered to accommodate
that weight. Additionally, ponding water on a roof can freeze. Often, water finds its way into a flashing seam and
freezes, weakening the seam.

For bitumen-based roof coverings maintenance also includes keeping the tar paper covered with gravel, an older
method, currently being replaced with bituminous roofing membranes and the like, which must be 'glued' in place so
wind and waves do not move it causing scouring and more bare spots. The glue can be any exterior grade glue like
driveway coating.

Roof maintenance also includes fixing blisters (delaminations) or creases that may not yet be leaking but will leak
over time. They may need experienced help as they require scraping away the gravel on a cool morning when the
tar is brittle, cutting open, and covering with plastic cement or mastic and mesh. Any moisture trapped in a blister
has to be dried before being repaired.

Roof coatings can be used to fix leaks and extend the life of all types of flat roofs by preventing degradation by the
sun (ultra-violet radiation). A thickness of 30 dry mils is usually preferred and once it is fully cured, you will have a
seamless, watertight membrane.






















Roof replacement is the largest capital projects undertaken at commercial and industrial buildings. We can help
navigate the structural, serviceability, and durability concerns to ensure the most appropriate roofing system is
specified. Flat roofs are usually supported by fluted steel decking on open web steel joists.

There are several types of roof  membrane systems is available, each with its own performance, cost, and durability
characteristics
  •    bituminous membranes, such as modified bitumen (mod-bit) or built-up felt and asphalt systems; and
  •    single-ply membranes, such as polyvinyl chloride (PVC), thermoplastic olefin (TPO), and ethylene
    propylene diene monomer (EPDM).

Some membrane systems are more resistant to ultraviolet (UV) exposure, while others stand up better to punctures,
tears, abrasion, or other physical damage. Some membranes are more resistant to thermal fluctuations or severe
climates, while others perform better from an energy perspective. In selecting a membrane, it is important to
carefully consider the service conditions. For example, an exposed single-ply membrane would not be advisable for
a roof with a large amount of rooftop equipment as it would be less resistant to inadvertent punctures or physical
damage caused by service contractors. Built-up membranes  occupy a substantial share of the Ontario market
because many relatively large, established roofers have invested in the kettles, tankers, and equipment required to
install built-up membrane systems.

Asphalt
Asphalt is an aliphatic compound and in almost all cases a byproduct of the oil industry. Some asphalt is
manufactured from oil as the intended purpose, and this is limited to high quality asphalt produced for longer
lasting asphalt built-up roofs (BUR). Asphalt ages through photo-oxidation accelerated by heat. As it ages, the
asphalts melt point rises and there is a loss of plasticizers. As mass is lost, the asphalt shrinks and forms a surface
similar to alligator skin. Asphalt breaks down slowly in water, and the more exposure the more rapid the
degradation. Asphalt also dissolves readily when exposed to oils and some solvents.

There are four types of roofing asphalt. Each type is created by heating and blowing with oxygen. The longer the
process the higher the melt-point of the asphalt. Therefore, Type I asphalt has characteristics closest to coal tar
and can only be used on dead level surfaces. Type II, is considered flat and can be applied to surfaces up to 1/4 in
12 slopes. Type III, is considered to be "steep" asphalt but is limited to slopes up to 2 in 12, and Type IV is "special
steep". The drawback is, the longer it is processed, the shorter the life. Dead level roofs where Type I asphalt was
used as the flood and gravel adhesive has performed nearly as well as coal tar. Asphalt roofs are also sustainable
by restoring the lifecycle by making repairs and re-coating with compatible products. The process can be repeated
as necessary at a significant cost savings with very little impact on the environment.

Asphalt built-up roof is made up of multiple layers of reinforcing plies and asphalt forming a redundancy of
waterproofing layers. The reflectivity of built up roofs depend on the surfacing material used. Gravel is the most
common and they are referred to as asphalt and gravel roofs. Asphalt degradation is a growing concern. UV-rays
oxidize the surface of the asphalt and produces a chalk-like residue. As plasticizers leach out of the asphalt,
asphalt built up roofs becomes brittle. Cracking and alligatoring inevitably follows, allowing water to penetrate the
system causing blisters, cracks and leaks. Compared to other systems, installation of asphalt roofs is energy-
intensive (hot processes typically use LP gas as the heat source), and contributes to atmospheric air pollution
(toxic, and green-house gases are lost from the asphalt during installation).

Modified Bitumen
A bitumen is a term applied to both coal tar pitch and asphalt products. Modified Bitumens were developed in
Europe in the 1970s when Europeans became concerned with the lower performance standards of roofing asphalt.
Modifiers were added to replace the plasticizers that had been removed by advanced methods in the distillation
process. The two most common modifiers are APP (attactic polypropylene) from Italy and SBS (styrene-butadiene-
styrene) from France. The United States started developing modified bitumen compounds in the late 1970s and
early 1980s.

APP was added to asphalt to enhance aging characteristics and was applied to polyester, fiberglass, or polyester
and fiberglass membranes to form a sheet good, cut in manageable lengths for handling. Usually applied by
heating up the underside of the roll with a torch provided a significant fire hazard and was outlawed in some
municipalities when buildings caught fire and some burnt to the ground. Another problem developed when a lack of
standards allowed some manufacturers to produce goods with amounts of APP insufficient to enhance the aging
characteristics.

SBS is used as a modifier for enhancing substandard asphalt and provides a degree of flexibility much like rubber.
It also is applied to a myriad of carriers and produced as a sheet-good in rolls that can be easily handled.

SEBS – (styrene ethylene butadiene styrene) is a formulation increasing flexibility of the sheet and longevity.

PVC (vinyl) membrane roofing
Polyvinyl Chloride (PVC) membrane roofing is also known as vinyl roofing. Vinyl is derived from two simple
ingredients: fossil fuel and salt. Petroleum or natural gas is processed to make ethylene, and salt is subjected to
electrolysis to separate out the natural element chlorine. Ethylene and chlorine are combined to produce ethylene
dichloride (EDC), which is further processed into a gas called vinyl chloride monomer (VCM). In the next step,
known as polymerization, the VCM molecule forms chains, converting the gas into a fine, white powder – vinyl resin
– which becomes the basis for the final process, compounding. In compounding, vinyl resin may be blended with
additives such as stabilizers for durability, plasticizers for flexibility and pigments for color.

Thermoplastic is heat-welded seams form a permanent, watertight bond that is stronger than the membrane itself.
PVC resin is modified with plasticizers and UV stabilizers, and reinforced with fiberglass non-woven mats or
polyester woven scrims, for use as a flexible roofing membrane. PVC is, however, subject to plasticizer migration. (a
process by which the plasticizers migrate out of the sheet causing it to become brittle.) Thus a thicker membrane
has a larger reservoir of plasticizer to maintain flexibility over its lifespan. PVC is often blended with other polymers
to add to the performance capabilities of the original PVC formulation, such as KEE – Keytone Ethylene Ester. Such
blends are referred to as either a CPA – Copolymer Alloy, or a TPA – Tripolymer Alloy.

Vinyl roofs provide an energy-efficient roofing option due to their inherently light coloring. While the surface of a
black roof can experience a temperature increase of as much as 90 degrees under the heat of the full sun, a white
reflective roof typically increases only 5–14 degrees Celsius (10–25 degrees Fahrenheit).

Vinyl membranes can also be used in waterproofing applications for roofing. This is a common technique used in
association with green, or planted, roofs.

FTPO
Flexible Thermo Polyolefin- correct acronym for the product TPO "Flexible"-retains flexibility "Thermo"-can be
reheated again and again, does not cure". "Polyolefin"-a polymer produced from a simple olefin. Flexible Thermo
Poly-Olefin is the exact physical and chemical name given to the product "TPO" Thermo Plastic Olefin. Although
TPO exhibits the positive characteristics of other Thermo Plastics, it does not however have any "plasticizers"
added to the product like other Thermo plastics. This mis-categorization made sense when the product was
introduced in the early 1990s and was unproven in the industry. TPO was categorized with thermo plastic
membranes that were similar in look and performance but were far from their real chemical and physical
characteristics of the TPO membrane. TPO was formulated to fix all the problems associated with other Thermo
plastic membranes. Having no plasticizers and chemically being closer to rubber but having better seam, puncture,
and tear strength, TPO was touted to be white weldable rubber of the future. From 2007-2012 reported sales of
TPO roofing products by all six major US manufacturers' report materials and accessories sales quadrupling all
other flat roofing materials. Gross sales of TPO membrane roofing in U.S.exceed all other flat roof types combined.
TPO's rapid market acceptance over the last twenty years by contractors, architects, engineers, and the market in
general shows it is living up to its original purpose and it's here to stay. TPO is also being touted as the green
solution as it is safer for installers and recycles 100% without chemical byproduct. TPO
- Thermoplastic Polyolefin
single-ply roofing can be fully adhered, mechanically fastened, or ballasted. TPO seam strengths are reported to
be three to four times higher than EPDM roofing systems. This is a popular choice for "Green" building as there are
no plasticizers added and TPO does not degrade under UV radiation. It is available in white, grey, and black. Using
white roof material helps reduce the "heat island effect" and solar heat gain in the building.

EPDM
Ethylene Propylene Diene Monomer is a synthetic rubber most commonly used in single-ply roofing because it is
readily available and simple to apply. Seaming and detailing has evolved over the years and is fast, simple and
reliable with many membranes including factory applied tape, resulting in a faster installation. The addition of these
tapes has reduced labour by as much as 75%.

It is a low cost membrane, but when properly applied in appropriate places, its warranted life-span has reached 30
years and its expected life-span has reached 50 years.

There are three installation methods: ballasted, mechanically attached, and fully adhered. Ballasted roofs are held
in place by large round stones or slabs. Mechanically attached roof membranes are held in place with nails, and
are suitable in some applications where wind velocities are not usually high. A drawback is that the nails penetrate
the waterproof membrane; if correctly fastened the membrane is "self-gasketing" and will not leak. Fully adhered
installation methods prove to give the longest performance of the three methods.

The most advanced EPDM has been combined with a polyester fleece backing and fabricated with a patented hot
melt adhesive technology which provides consistent bond strength between the fleece backing and the membrane.
This has resulted in largely eliminating shrinkage of the product, whilst still allowing it to stretch up to 300% and
move with the building through the seasons. The fleece improves puncture and tear resistance considerably and .
045 mil EPDM with a fleece backing is 180% stronger than .060 mil bare EPDM. Fleece backed EPDM has a tear
strength of 39.9N/mm compared to 13.1N/mm of that without the fleece reinforcement, more than 3X the strength of
non-reinforced membranes

Asphalt Composite Shingles - For Sloped Roof
Replace with Algae Resistant Architectural Shingles (Not Standard 3 Tab Asphalt Singles) - When replacing
shingles, install ice and water shield, replace all flashings and check the sheathing for damage.

Effective roof drainage depends not only on an adequate number of drains, but also effective slopes to those
drains. In conventional roofing assemblies, where the membrane is installed atop the insulation, tapered insulation
boards are frequently used to slope the membrane surface toward the drains. Improperly installed overlays can
affect roof drainage, particularly when installed on a roof that already had problematic drainage.

Wind moving across a flat roof can impose suction forces that could uplift the roof covering. The membrane and
perimeter flashings must be designed to resist wind uplift. Securing a roof is typically achieved by weighing down
the roofing with ballast, mechanically fastening the assembly to the structural roof deck, adhering the roofing
system components together, or a combination of the above. Most manufacturers’ guidelines to resist wind uplift
were not created for Canadian codes. Some product providers do test to conservative standards, such as those
established by Factory Mutual (FM) for loss prevention purposes.

Roof replacement is the single largest cost item to a commercial / industrial building, so it is imperative building
owners, condominium corpoartions, and property management staff approach roof projects with extreme level of
due diligence. The best strategy to ensure a successful reroofing project is to use a comprehensive specification
that addresses every aspect of reroofing and clearly delineates all roofing products contractors will use.

The reroofing specifications include
  •    List of manufacturers and verify their products are compatible with existing roof and building components.
  •    Incorporate the building owner's needs and expectations and spell out these items for bidding contractors.
  •    Address all roofing products and have detailed drawings detailing the system installation exactly. These
    specifications must meet or exceed all manufacturers' requirements for the warranty.
  •    Demand insurance and bonding based on the size of the project. This stipulation assures the building
    owners the bidders can perform the work and carry policies that protect the building owners.
  •    Include line-item pricing on tasks such as deck replacement, which would protect the organization from
    inflated as-needed materials.
  •    List material warranties — typically 20 years — and contractor guarantees — at least five years.

Besides such detailed specifications, building owners and property managers also should give serious
consideration to investing in project management by an engineering firm specializes in roofing to ensure the project
adheres exactly to specifications. Mandatory pre-bid attendance on site and avoiding voluntary substitutions will
ensure all bidders are familiar with the job site and conditions, and it will ensure they do not bring to the site
products building owners and property managers might find less desirable.

Even though warranties and guarantees are part of the specification package, managers must remember these are
marketing tools and should never be the sole consideration for choosing a contractor or manufacturer.

We prepare comprehensive specifications for roof replacement to meet the building owner’s or
condominium corporation property management's criteria for performance and budget considerations.
Proper specifications for roof replacement saves thousands of dollars due to the competitive bidding
process where qualified members of
Canadian Roofing Contractors Association members submit
tenders for the same scope of work.
Our Roof Replacement Service includes
  •    Review of existing roof
  •    Prepare comprehensive of specifications for roof replacement
  •    On-site meeting with roofing contractors. Issuance of addenda and change orders as necessary
  •    Perform the periodic field reviews of roof replacement to assess contractor performance and
    quality of the work, and to ensure compliance with specifications and contract documents.

Whether a re-roofing or a overlay project, roofing is a complex subject. Among the many issues are determining
what is on a roof, how it is used, how poor drainage will be corrected, how obsolete rooftop equipment will be
removed, and whether the remaining curbs and penetrations will have sufficient clearance so that additional
thermal insulation, if needed, can be added.

If there is no one in-house with the capability to make these determinations, then a qualified roof condition
assessment may fit the bill for building owners, condominium corporations and property management companies..
The roof condition assessment, in turn, may recommend a structural analysis if the weight of the new roof system
will be significantly heavier than what is there (i.e., a ballasted roof system). If there is a suspicion that asbestos
may be found in or under the existing systems, we may recommend checking this out well before the reroofing
begins, usually by a confirming laboratory analysis. Our roof condition assessment specialist's observation will
include verification of condition of roofing materials stored on-site and compliance with specification documents;

Our roof condition assessment experts determine whether the roof work is being performed in a manner that, when
fully completed, will be in accordance with the roofing contract documents.

Our certified roof condition assessment experts perform evaluations of existing roofs, plan roof design solutions,
prepare roofing construction documents, perform forensic roof inspections, monitor roof construction, and serve as
expert witnesses. Our roof condition assessment experts possess a broad base of practical knowledge about the
roofing industry at large.

Our roof condition assessment experts strive to ensure that the roof replacement project is constructed according
to the roof replacement contract documents. Our roof condition assessment experts work to ensure that proper
application procedures are followed, and that criteria for validation of manufacturer’s warranties are met. Our roof
condition assessment experts have training, experience and familiarity with the roof replacement project
requirements and products being installed. Our roof condition assessment experts have thorough understanding of
the manufacturer’s materials and installation requirements.

The most significant factor contributing to  staggering amount of financial commitment towards roof
maintenance and replacement is the lack of a comprehensive pro-active approach towards extending
the service life of the existing roof. Establish a assessment schedule to anticipate trouble areas in the
early stages. Minor problems can be identified and corrected before roof leaks cause serious and
costly damage to the roof system and interior of the building. A regular roof condition assessment can
greatly increase a roof’s lifespan and give building owners peace of mind. Roof condition assessment
along with preventive maintenance are ongoing tasks that should not be neglected by the building
owners. We recommend having your roof condition assessed regularly. Roof is one of those items that
is out of sight, out of mind. Detecting a potential roof leak and identifying the more-subtle problematic
areas early enough can prolong the useful roof covering life. The cost of a visual roof condition
assessment is minimal when compared to the amount of money required to replace an entire roof. Our
professional commercial roof condition assessment experts identify immediate and long-term
necessary roof repairs and provide recommendations for remedial actions and the costs associated
with.
