Roofing systems.
D. C. Taylor Co. has substantial experience installing a wide variety
of roofing systems and is approved by the major roofing material manufacturers.
Because we work with different systems and have applied them to thousands
of different roofs, you can be assured you’re not getting a one-size-fits-all
recommendation. Don’t know what your roofing needs are? Want a proposal

Single-Ply (Elastomeric)
EPDM.
EPDM (ethylene propylene diene monomer) is an elastic synthetic rubber.
Because it is fully cured, seams are formed using contact adhesives or tapes.
Seams and flashings require careful attention. EPDM is lightweight, flexible
and usually black. It is available reinforced and non-reinforced, fire retardant
and non-fire retardant, and varies in thickness from 45 mil to 90 mil.

Single-Ply (Thermoplastic)
Heat Welded Membrane Systems.
Flexible, reinforced, heat weldable membranes are manufactured from a variety
of materials. D. C. Taylor Co. installs a number of PVC, TPO, Elvaloy®
and Hypalon® membrane systems. Most thermoplastics are reinforced and
fire retardant. Selection of the most appropriate membrane requires knowledge
of the specific conditions on each roof, including the building environment
and physical stresses to which each individual roof is exposed, and the
performance of each membrane. Thermoplastic membranes are lightweight, energy
efficient and aesthetically pleasing. They adapt well to unusual shaped
buildings and to buildings that experience substantial movement. Various
membranes exhibit good resistance to environmental contaminants—including
animal fats, chemicals, particulates and liquids–and roof traffic.
Heat welding allows thermoplastics to be installed in a wide range of temperature
conditions and produces seams and flashings that are judged as superior
to EPDM systems.

Built-Up Roofing (BUR).
The roofing membrane is built up by alternating layers of asphalt or coal
tar saturated felts or fiberglass mat roofing plies. The built-up roof components
are: insulation board, base sheet, hot- or cold-applied felts, surfacing
materials and flashing materials. These systems can be durable and long
lasting when carefully installed in multiple layers with quality bitumen,
felts and flashings. Built-up roofing (BUR) can be used in both new construction
projects and on existing buildings. BUR systems have low flexibility and
are only appropriate on roof decks with minimal movement or where appropriate
expansion joints are provided. BUR systems require periodic maintenance
to maximize their service life. In some installations, BUR can be designed
to be more durable and resistant to casual roof traffic.

Modified Bitumen (MB).
Composite membranes consisting of bitumen, modifiers and a reinforcement
such as fiberglass or polyester. The modifiers provide a tough, rubbery
property to the product and add flexibility. Modified bitumen sheets are
manufactured in a consistent, controlled environment and are generally coated
or covered with mineral granules. Modified bitumen systems are more flexible
than BUR systems, yet share many of the advantages, including good resistance
to roof traffic. They are a good choice as a replacement for a BUR system
or on certain high traffic roofs.

Polyurethane Foam (PUF).
A two-part liquid mixture that is spray applied to the roof deck or substrate.
It immediately expands from 20 to 30 times its original volume, hardens
and becomes a lightweight, solid insulation. Used in combination with protective
coatings or membranes that are specifically designed for use over polyurethane
foam. Offers the best insulation efficiency per unit of thickness and excellent
waterproofing qualities. It adheres to virtually all types of roof decks,
is self-flashing and has good strength/weight ratios.

Coatings.
Synthetic sealants are formulated from a variety of materials to form
a strong, flexible seal that will not dry out or become brittle. Selection
of the most appropriate coating requires knowledge of roof conditions,
coating properties and cost considerations. Coatings are used to protect
polyurethane foam, metal, modified bitumen and certain built-up roofs
from ultraviolet damage. Coatings can also be used to waterproof some
single-ply and metal roofs.

Standing Seam Metal.
A weather-tight, standing seam roof that acts like a single, monolithic
steel membrane. Roof panels are lock seamed together to keep moisture
out and assure structural integrity. Standing seam roofs can be durable
and very long lasting when carefully installed on appropriate buildings.
Can be used in new construction, retrofit of existing or re-cover to create
slope. Installation and detail quality are very important. There are a
wide range of metal roofs of varying cost and quality that do not perform
as well as a high-quality standing seam metal roofing system.
