Professional membrane roofing for residential low-slope roof sections, additions,
porches, garages, extensions and reroofing projects. RoofNow™ can evaluate your
existing roof and recommend a suitable modified bitumen roofing system for the project.
A roofing service built around the needs of Ontario homeowners
Low-slope sections of a home require a roofing approach that accounts for drainage,
roof geometry, transitions, penetrations and flashing details. RoofNow™ treats the
low-slope section as a complete roofing system rather than simply covering it with a surface material.

Homeowner FAQ
RUBEROID® Torch Smooth roofing questions
What is RUBEROID® Torch Smooth?
It is a smooth-surfaced APP modified bitumen membrane with a non-woven polyester
reinforcement. GAF identifies it as an APP base/ply sheet.
Is Torch Smooth the finished exposed roof surface?
The manufacturer identifies RUBEROID® Torch Smooth as a base/ply sheet. RoofNow™
determines the complete roofing assembly and appropriate finished system for each project.
Can it be used for reroofing?
Yes. GAF identifies RUBEROID® Torch Smooth for both new roofing and reroofing applications,
as well as flashings.
Can it be used for roof repairs?
GAF states that the membrane is also suitable for repairs of built-up roofing membranes
or other modified bitumen systems. Existing roof conditions still need to be evaluated.
Is this a DIY roofing system?
RoofNow™ offers it as part of a professional roofing installation service. Heat-weld
membrane roofing requires specialized equipment, proper system detailing and fire-safety procedures.
Need a low-slope roof installed in Ontario?
Contact RoofNow™ to discuss your residential project and find out which modified bitumen
roofing assembly is appropriate for your home.
Torch down roofing is a type of modified bitumen membrane roofing
commonly considered for low-slope roof areas where conventional
asphalt shingles may not be appropriate.
Systems can include a smooth base or ply membrane together with
an appropriate cap sheet or finished roofing layer, depending on
the roof design and manufacturer-approved assembly.
GAF identifies RUBEROID® Torch Smooth as an APP modified bitumen
base/ply membrane with polyester reinforcement and a heat-weld
application.
Important Things Homeowners Should Understand
It is intended for low-slope roofing applications.
The complete roof assembly should be selected according to the
specific roof design and conditions.
It is a membrane roofing system.
Modified bitumen roofing is different from traditional asphalt
shingles used on steeper residential roofs.
Multiple roofing layers may be involved.
A smooth membrane such as RUBEROID® Torch Smooth may function
as a base or ply within a complete roofing assembly.
It can be used for new roofs and reroofing.
The manufacturer also lists flashing and compatible repair
applications.
Roof condition matters.
Drainage, roof slope, decking, existing materials, penetrations
and flashing details should all be reviewed before a system is selected.
Professional installation is important.
Heat-weld membrane systems involve specialized roofing equipment,
system detailing and fire-safety requirements.
RoofNow™ Homeowner Note:
Torch-applied membrane roofing should not be treated as a DIY roofing
project. RoofNow™ evaluates the existing roof and determines the
appropriate materials and roofing assembly before installation.
For Ontario Homeowners
Is Torch Down Roofing Right for Your Home?
Torch down roofing may be considered when your home has a low-slope
roof section that requires a membrane roofing system rather than a
conventional steep-slope roofing material. The right system depends
on the condition and design of your individual roof.
01
You Have a Low-Slope Roof Area
Low-slope sections can appear on additions, extensions, garages,
porches and portions of the main home. These areas may require a
different roofing system than the steeper sections of your roof.
02
Your Existing Roof Needs Replacement
GAF identifies RUBEROID® Torch Smooth for both new roofing and
reroofing applications. RoofNow™ can evaluate your existing roof
to determine which system is appropriate.
03
You Have Problem Roof Transitions
Areas where a low-slope roof meets walls, steeper roofing,
chimneys or other roof sections require careful flashing and
waterproofing details.
04
You Want the Roof Professionally Assessed
Roof slope, drainage, decking, existing materials and flashing
conditions can all affect the recommended roofing assembly.
RoofNow™ reviews these conditions before recommending a system.
05
Your Roof Has Previous Membrane Roofing
RUBEROID® Torch Smooth is also identified by GAF as suitable for
certain repairs involving built-up roofing membranes or other
modified bitumen systems.
06
You Want a Complete Roofing Solution
A low-slope roof is more than the visible membrane. The complete
system can involve multiple roofing components, flashing details
and transitions selected for the specific home.
Not Sure What Type of Low-Slope Roof You Have?
Send RoofNow™ photos and information about your roof and we can
help determine the next step for your Ontario home.
Low-Slope Roofing Facts Ontario Homeowners Should Know
Ontario homes can include low-slope roof sections over additions,
garages, porches and extensions. These roof areas have different
drainage and waterproofing needs than conventional steep-slope roofs.
Understanding those differences can help homeowners make a better
roofing decision.
01
Low-Slope Does Not Mean No Slope
Even a roof that looks flat should be designed to move water
toward appropriate drainage points. Positive drainage helps
reduce unnecessary water accumulation on the roof surface.
02
Modified Bitumen Is Made for Lower Slopes
Ontario’s roofing provisions recognize
modified bituminous membranes as a distinct
roofing category suitable for substantially lower slopes than
conventional asphalt-shingle roofing.
03
Ontario Winters Make Drainage Important
Snow, melting snow, rain and freezing temperatures can all affect
residential roofs. Drain locations, roof transitions and areas
where water can collect deserve particular attention on a
low-slope roof.
04
The Roof Deck Matters
A membrane is only one part of the roofing system. Existing
decking should be assessed for deterioration, moisture damage
and other conditions before a replacement roofing system is installed.
05
Flashings Are Critical
Roof-to-wall connections, vents, chimneys, drains, edges and
transitions between low-slope and steep-slope roofing are
important waterproofing details.
06
Moisture Can Come From Inside the Home
Not every moisture problem starts with rain. Warm, moist indoor
air can move into roof assemblies through air leakage, which is
why insulation, air sealing and roof-system design can matter.
07
Smooth and Granulated Membranes Have Different Roles
RUBEROID® Torch Smooth is identified by GAF as an
APP base/ply sheet. A complete modified-bitumen
system may use different membrane components depending on the
approved roof assembly.
08
Existing Roofing Must Be Evaluated
Before reroofing, RoofNow™ can review the existing membrane,
roof deck, drainage, penetrations and transitions to determine
what work is appropriate for the home.
09
Torch-Applied Roofing Is Professional Work
Heat-weld membrane installation requires specialized roofing
equipment, correct detailing and appropriate fire-safety
procedures. RoofNow™ offers it as a professional installation service.
ON
Ontario Roofing Fact
Ontario Building Code roofing provisions list modified bituminous
membranes with a minimum roof slope of 1 in 50
and a maximum slope of 1 in 4. The suitability
of any individual roof still depends on its complete design,
materials and applicable requirements.
Why this matters for homeowners:
A low-slope roof should be approached as a complete waterproofing
and drainage system. The membrane, substrate, flashing details,
drainage, insulation and transitions all work together. RoofNow™
evaluates the existing conditions before recommending a roofing solution.
