Introduction
The Goal of this Roofing Guide �� "�`'' `
rnsiffir
It seems simple enough.A roof is expected,at the very least,to keep • ti, J
(r -
water from getting into a building.If you're a building owner you may _, _ -- ! -_
not think about your roof until it leaks.If you're an architect you are '-- - _
expected to get it right,the first time. But the fact remains,over 50% , la
of all building litigation revolves around water entry into the building,so
III
getting it right apparently isn't easy.
There are three (3) keys to a successful roof installation: . > a , � fir.
1. Good design . s ` '
2. Quality materials and assemblies A ��.. �f� MN ��
3. Experienced workmanship ill
;r
The design professional has great control over the first two and can Good Design
certainly establish the parameters of the third. If any of the three keys
miss the mark,it's not a question of if the roof will leak,but when.
No matter if the structure is an office tower,a health care facility, .�...--...Vt.
�` :a ',4r . ;
part of a university or museum;these buildings are built to last.Why s, ' ':�,A =� -r . < `.''
7.
shouldn't the roof membrane assembly chosen be equal to the task?If bs � i �'r
your building absolutely"can't leak"and you only want to do this once,
then recognize initial cost isn't as important as long-term performance.
The initial cost of a quality roof installation will ALWAYS be much less
than the cost to replace one that has failed prematurely. Remember,
you typically get what you pay for.
The focus of this guide is Hydrotech's flag ship product,Monolithic
Membrane 61253 (MM61253);a hot fluid applied, rubberized asphalt .111101°
membrane which forms the foundation of each of the Protected
Membrane Roof(PMR)Assemblies Hydrotech provides.
Just what is a PMR Assembly?That's a very good question!In the
following pages,you'll get a clear understanding of the PMR Assembly `
and the huge advantages it offers over conventional roof assemblies
available in the marketplace.
So,how does Hydrotech contribute to the 3 keys of a successful roof
installation?

STYROFOAMTM XPS Insulation Advantage
Dow STYROFOAM" XPS Insulation
Dow developed STYROFOAM-''' extruded polystyrene insulation in the
1940's. In the early 1970's Dow obtained a patent and introduced the
IRMA—Insulated Roof Membrane Assembly.Early on this approach
was referred to as an"upside down"roof and is known more widely
today as the Protected Membrane Roof(PMR)Assembly.
Placing an insulation layer on top of a roof membrane,not beneath it,
demands that the insulation be able to withstand direct exposure to
a roofs harsh environment. Before STYROFOAM'',no existing roof
insulation product could be placed above a roof membrane because
of one or more performance issues.An insulation in this configuration
would need to be resistant to moisture absorption,provide long-term
thermal performance,be dimensional stable and durable.
STYROFOAM'",an extruded polystyrene was the only answer,and it
still is today.
STYROFOAM's Features and Benefits Types
• Excellent moisture resistance • STYROFOAM" extruded polystyrene insulation is typically
• High compressive strength available in 2'x 8'boards and in nominal thicknesses ranging from

The Protected Membrane Roof (PMR) Advantage
Conventional Roofing Design
With a conventional roof assembly,the roof membrane is typically
placed on top of an insulation layer and structural deck. In this
configuration,the roof membrane is doing double duty-protecting the
building and its contents,as well as the insulation's thermal value. �, ; , ,.rim•_. s, ; ••• ,

If a breach in the roof membrane occurs and the insulation gets wet, •4, 'yid i G%i ' `i; sSv: •i
it loses its ability to perform as a thermal barrier. If the membrane is
attached to the insulation,failure of the adhesives or delamination
of the insulation facer can lead to roof blow off.Replacing the wet
insulation and repairing the roof membrane could be quite involved and
expensive. • -a

The Protected Membrane Roof (PMR) Assembly Membrane Temperature Changes
Reversing the arrangement of roofing materials,with the membrane Let's take a closer look at the temperature stresses a roof assembly
below the insulation, has been referred to for decades as an Insulated can experience. In 1976,The Corps of Engineers, U.S.Army,

referred to as a Protected Membrane Roof(PMR). and compared them to conventional roofs.The CRREL Report 76-2
The two biggest benefits a PMR Assembly provides when compared "Protected Membrane Roofs in Cold Regions,"was the result of

placed above the roof membrane from both physical abuse and Mother temperature in a protected membrane roof does not change more than
Nature. 5°to 10°F(3-5°C)from the average room temperature throughout the
year.Therefore,thermal stress on the membrane is eliminated.

Physical Damage
A roof membrane that is exposed can be easily damaged. In a conventional
roof assembly,once the membrane is breached,the insulation layer below
can become wet and lose its thermal value. Since water can be trapped
within the insulation layer,large areas of the roof could be affected.
Isolating the damage and making the subsequent repairs can be
costly,not to mention the potential for damage to the building's
interior finishes.

Components of a Protected Membrane Roof
It Starts with the Membrane
A typical Protected Membrane Roof(PMR)Assembly consists of a few
basic components;a structural deck,membrane,insulation and ballast.
Each component serves a specific basic function.A roof is simply r4_
expected to be watertight and properly insulated.However,in this L.g ! ;.��;4-L .: 6,

® Stone Filter Fabric—Its function is to simply keep stone fines
or particles from getting into the insulation board joints and helps
raft the insulation together.
® Insulation—Placed above the roof membrane, only an extruded 0
polystyrene insulation is utilized. Dow's STYROFOAM— Brand
Insulation has been used in PMR assemblies for more than 40+
years because it exhibits excellent moisture resistance,is closed

Paver Ballasted Assembly
Concrete pavers are another commonly used material for ballasting
a PMR Assembly. The typical concrete paver is a 24"x 24"x 2"
unit,weighing a minimum of 22 pounds per square foot. If installed
over the entire roof surface (or a minimum of 10%of the roof area),
they must be set on support tabs to elevate them off the Dow
STYROFOAM"Insulation.
Concrete pavers are also used in conjunction with stone ballast to
provide additional ballast securement at perimeters and in corners
where the uplift pressures are typically greatest.At times it may even
be necessary to secure one paver to another with metal strapping,
running parallel to the building perimeter.Provided the pavers are
less than 10%of the roof area they can be set directly on the Dow
STYROFOAM" Insulation.
" Concrete pavers are also used to provide a foot path on the roof to
`'"'� HVAC units or other areas where maintenance may be required.

Paver Ballasted Ultimate Assembly®
Concrete pavers make an ideal surface for podium decks or roof
terraces that will be accessible for use by the building occupants. In
this application concrete pavers not only provide the ballast needed
for the roof,but an aesthetic finished surface as well. Instead of
being installed on support tabs that follow the slope of the roof
surface,these pavers are typically supported on pedestals. Pedestals
and related accessories elevate the paver to the desired height and
compensate for the roofs slope below,so that the pavers can be set
level.
This open joint configuration allows water to drain off the paver surface
quickly,flowing to concealed drains below,eliminating issues seen
with pavers in typical setting bed applications.
Access to the components of the roof assembly below low is easy,so
maintenance and future alterations are easily accomplished.

Concrete Topping Split Slab Assembly
A Concrete Topping Split Slab PMR Assembly is sometimes used in
parking deck roof applications and as an alterative to stone or concrete
paver ballast where high wind uplift issues are a concern.
Concrete topping slabs have also been used at a buildings perimeter
-- ` and corners where davits and window washing tracks can be
��
found and uplift pressures are at their highest.This perimeter run of
concrete provides an easy walkable surface while protecting the roof
• -"z;-1.__. _ assembly below from physical abuse. If a slab accounts for 10%or
less of the total roof area the concrete can be placed directly over the
STYROFOAM'" insulation. Stone or paver ballast is typically placed
over the balance of the roof.
� In some cases where the concrete topping slab is placed over more
than 10%of the roof area, Hydrotech's Hydrodrain 300 is required.
/ The drainage layer should be placed between the insulation and
roz,,,,- * •_ the concrete slab to create a"diffusion open"assembly for the
°.. ,mor,T. STYROFOAM' and facilitate drainage.

Blue Roof Assemblies
Blue roofs are increasingly being employed to manage stormwater on
the roof top.With the ability to temporarily store large amounts of rain
water, blue roofs make ideal protected membrane roof assemblies.
Stone Ballast Blue Roof Assembly
Hydrotech's Stone Ballast Blue Roof is the simplest blue roof that can
be created. Using standard ballast stone,the water in the blue roof
�` ''L is temporarily stored within the void spaces of the stone and to the
a. z , tsE-a
1, .r} required depth above the ballast.A heavier than typical application
• ar. }•• of stone ballast is designed to keep the loose-laid STYROFOAM—
.� insulation from floating during those rain events when the blue roof is
— in operation.
A Hydrotech PMR Blue Roof is ideal for those utilitarian roofs that are
not designed for tenant use.
Stone Ballast Blue Roof Assembly
Ultimate Assembly Blue Roof Assembly
_ Hydrotech's Ultimate Assembly Blue Roof utilizes concrete
pavers set with pedestals over the STYROFOAM— insulation.The void
space created under the pavers is an ideal location to temporarily store
large quantities of stormwater.The paver weight is designed to keep the
.+ loose-laid STYROFOAM" insulation from floating during those rain events
when the blue roof is in operation.As a result,heavier,thicker pavers are
typically required.
A rooftop terrace is an ideal application for this blue roof assembly.
Because the pedestals supporting the pavers are adjustable,this blue
roof assembly may be ideal for roof decks with some roof slope where
the goal is to create a level,finished surface.

Garden Roof" Blue Roof Assembly
This version of Hydrotech's Blue Roof Assembly combines the
performance of the Garden Roofs Assembly and free water detained
in a voided space into one, creating a high performance stormwater
management solution.The core of this assembly is the water storage
unit-Permavoid8.
Architectural pavers can be installed to create pedestrian spaces
and to provide access to roof parapets and mechanical equipment.
Garden Roof®components can be used to create extensive green
roofs on top of the Permavoid units.Additionally, LiteTops within the
Garden Roof Assembly can increase the water holding capacity of this
composite Blue Roof Assembly.

Cool Roof Options
Hydrotech's Cool Roof Options
The roofing industry at large,architects and government agencies
typically view white single-ply or modified bitumen sheet membranes
as the only cool roof options available. Protected Membrane Roof
designs can also satisfy this requirement while also providing
many other substantial benefits,most important of all...long term _
performance.
The solar reflectance and thermal emittance of a surface is referred ' •y \I --
to as the Solar Reflectance Index number,or SRI.The SRI is defined �`\
as an alternative metric for comparing the coolness of roof surfaces. - .• '{� _
The higher the SRI,the cooler the roof will be in the sun. For example, vac f.', .: ,
a clean black roof has an SRI of 0,while a clean white roof has an SRI I‘ .
of 100.A minimum SRI value of 78 is required in order to qualify for �`
LEED8 points. S`�Si1rR:

Installation Basics
Membrane Preparation --
Before Monolithic Membrane 61253 can be installed,the material i A
must first be melted in a double-jacketed melter.Today's melters A 1
employ electronic temperature gauges,automatic shut off I 1
mechanisms and other design features,making safety a priority.The I - .
typical melter today is air-jacketed meaning the heat source first
heats an air chamber that in turn heats up the membrane in the inner
chamber. Oil-jacketed melters,where heat transfer oil fills the outer
chamber,are also still commonly used. Propane, diesel and electrically
operated melters are all currently available. Melters are sized to fit 111)
just about any job site condition,a 35 or 100 gallon melter are small
enough to fit into an exterior building lift or elevator. Larger 200 or 4000
gallon melters are also available to maximize production on a project.
DcL7ie JacXeted f.ete,
A mechanical agitator inside the melter keeps the melted material _
moving,ensuring the uniform transfer of heat throughout the membrane.
The membrane is brought up to a temperature of 350°F before it is

drawn off from the melter to be applied to the roof substrate.

Concrete Finish fr Curing - . _
A poured-in-place concrete surface (horizontal) should be finished to r • •
a rough texture to provide a mechanical bond for the membrane.The - . . .
texture however,should not be so rough that the membrane cannot be , • • ' ' .- .•
applied at a continuous thickness across the surface.As a minimum, . -
a wood-float or broom finish is required,with a wood-toweled finish -- r0, . .
preferred.A steel-toweled finish is NOT desirable. Per the International . - • "
Concrete Repair Institute (ICRI) Concrete Surface Profile (CSP) _ - .
Guidelines,a CSP of between 3 and 6 is ideal. , -.
Probably the most important factor in assuring that the concrete will .
attain its full strength and durability is to insure it is properly cured. -. . r .
There are several curing methods that are acceptable to Hydrotech, ..`.,•,- z .-- -, 4 _ •
-
including water curing,wet coverings,plastic sheets and liquid s'-� ` • -
applied curing compounds.The vast majority of the time liquid applied cancrele finish-wood trowel°r'nomad
curing compounds are used due to their easy of application and low ``.'"--e"110'
cost.There are many different types of curing compounds available, '~__-` --'
v.
however,most are not acceptable to Hydrotech because they leave a _ _r _ '
film on the concrete surface that would interfere with the bond of the .-
membrane to the concrete. Sodium silicate-based curing compounds
do not leave a surface film and are acceptable.
IL-
In renovation work any existing membrane bonded to the concrete
surface must first be removed.The best method for removing an - •t N
existing membrane depends on the type of membrane and how it was -4019011°-
applied.
Simple Substrate Detailing ,
Monolithic Membrane 61253 detailing is simplified,with a minimum of ,
3 layers of protection in every condition. Shnnlegecracks>1/1e and<114'
Typical shrinkage cracks do not have to be detailed prior to the field -- _. mr-
application of the membrane.
For cracks over 1/16"but less than 1/4"and cold joints,a 6"strip - '•-- _ --- _
of Flex-Flash F or Flex-Flash UN is centered over the crack or joint, '
embedded into and top coated over with MM6125. N . _ _
Precast concrete joints (side and end) need to be filled with a backer -----4 _ -..
rod and sealant prior to detailing with Flex-Flash UN. - - _ . '
Monolithic Membrane 6125 Application t
F- .-
On a horizontal deck the membrane is applied with a straight rubber -
bladed squeegee.As a rule of thumb,an evenly applied 1.4 lbs of '
membrane per square foot will ensure proper coverage (215 mils).

achieved.
The typical MM6125-FR (fabric reinforced)assembly consists of -— __-__ -
first applying a coat of MM6125 to the substrate at a minimum - -_- -
thickness of 90 mils (2.3MM),into which is immediately embedded - —�
a layer of Flex-Flash F reinforcing fabric.A second coat of MM6125, ---
at a minimum thickness of 125 mils (3.2mm),is then applied,totally _
encapsulating the Flex-Flash F within the membrane. •�

The following two pages are intended to give you a brief description of ' ��� 11- .'
a typical application on a poured in place concrete substrate. Keep in
mind every project is different.
Deck Preparation
The Hydrotech authorized applicator typically determines at the
beginning of the day's work the size of the area they expect to
complete that day.Once the area has been determined,the concrete
substrate must be cleaned prior to the installation of the Monolithic
Membrane 61258 membrane assembly.Typically,the concrete 0:1w
substrate would be broom cleaned of any debris and dirt and then f,
blown with an air compressor to remove any remaining dust.The '" .;,_-_---+• • -..,. -3.•-. '• • aP
substrate must be clean prior to the application of the membrane. .ir.-i . . .
Surface Conditioner _ Suffice conditioner aopied
Hydrotech's Surface Conditioner should be spray applied to the Pm A iiiiimEtt .

Typical Detailing Conditions
Common Detailing - _
Detailing work utilizes Hydrotech's Flex-Flash F(fabric)or Flex-Flash -- -
UN (uncured neoprene) reinforcing sheets encapsulated between two ut I
layers of MM6125.Flex-Flash F is typically used to reinforce cracks •
and changes in plane. Flex-Flash UN is used as a reinforcing at drains,
expansion joints and any transitions between dissimilar construction
materials.It is also used as a flashing for exposed parapets,walls and
curbs.Hydrotech's Flex-Flash MB,a modified bitumen sheet membrane
may also be used in exposed flashing conditions.Hydrotech's MM6125 . _
membrane is NOT acceptable for use as an exposed flashing. •
Good roofing practice dictates that all flashings terminate 8"-12"on
the vertical,above the topping materials.In all cases the application
of the membrane in the field of the roof overlaps and ties into the Pd a/c9vitCBtai/ed
detailing conditions.
Hydrotech has several acceptable methods for flashing curbs,parapets ,,
and other conditions. For additional detailing information please refer to
Hydrotech's installation guidelines and details. •_ ,;,
Pipe/Penetration Detailing
All penetrations (pipes,angles,vents, etc.) passing though the - _"
membrane must be rigid and properly secured to, or cast into the . =- '.t ,
deck. For conduit or larger diameter pipes,a piece of Flex-Flash UN ''1",.
is placed at the base,extending a minimum of 4"in either direction
of the penetration,with a hole in the center 1"less in diameter than
the pipe diameter.This insures that the flashing comes up onto the . _ ---_ " -
penetrations to form a good seal.A second sheet of flashing wraps the -
i e penetration and is typicallyterminated with a metal band clamp. ''••

has been completed. _ . •
With the clamping ring removed,membrane is applied around the
drain,from the inside edge of the drain bowl,out several feet around - • .
the drain in all directions.Typically a 3'x3'sheet of Flex-Flash UN will - . "
suffice.The reinforcing sheet is set into membrane,centered over ..•
the drain bowl.Once the drain clamping ring is placed,the Flex-Flash • . . f . K:
•
UN should be coated with membrane up to the clamping ring,totally — .1.' . • •

Typical Curb Detailing - �,,,•
Curb flashing can be detailed with Flex-Flash UN, extending down the Y` • \
Curb flashing xutailed

MM6125,3"on the horizontal and 3"up the vertical leg.The Flex-Flash •` ,� ''.- °"
UN is set in bonding adhesive on the vertical the full height of the curb.
Typical Parapet Detailing \ .
Parapet flashing with Flex-Flash UN is handled like a curb,with
the flashing extending much higher on the vertical.To protect the : ~4�`
membrane flashing,it is advisable to cover it with sheet metal counter u
flashing.An alternative approach would be to cover it with Hydrotech's Hydroguards (see photo at right). Other flashing methods utilizing _Hydrotech's Flex-Flash MB,a modified bituminous sheet membrane,
are available as well. A
