A proper flat roof installation starts with assessing the deck and structure, then building the system in layers — vapour control, insulation to code, and a waterproof membrane — with careful attention to slope, drainage, and flashing at every edge and penetration. Iron Shield Roofing installs each layer to manufacturer specification so the finished roof performs through Edmonton's freeze-thaw cycles, snow loads, and temperature swings.

Iron Shield Roofing installs all the major low-slope systems used in Edmonton: TPO, EPDM, and PVC single-ply membranes, SBS modified bitumen, and traditional tar-and-gravel built-up roofs. The right choice depends on your building, budget, and how the roof will be used, and we walk you through the trade-offs before any work begins.

There's no single best system — it depends on the building — but in Edmonton's climate the priorities are proven cold-weather performance, strong seams, and resistance to freeze-thaw movement and UV. TPO and SBS modified bitumen are both popular, durable choices here; Iron Shield Roofing recommends the system that fits your structure, drainage, and long-term plans rather than a one-size-fits-all answer.

Most residential and small commercial flat roof installations take from a couple of days to about a week, depending on the size, how many layers need to come off, roof access, and the weather. Larger commercial projects take longer and are scheduled in phases. Iron Shield Roofing gives you a realistic timeline up front and keeps you updated as the work progresses.

Yes — flat roofs can be installed in winter, but it takes the right materials and methods. Cold-weather installation requires careful adhesive and membrane selection, attention to substrate temperature, and systems rated for low-temperature application. Iron Shield Roofing plans winter installations around suitable weather windows so the roof is installed correctly rather than rushed.

Flat roof installation costs in Edmonton depend on the size of the roof, the system you choose, how much tear-off and insulation is required, and the complexity of the drains, penetrations, and details. Because every roof is different, the most accurate way to know is a free assessment and written quote from Iron Shield Roofing rather than a generic per-square-foot figure.

Yes. Iron Shield Roofing installs flat roofs on new construction as well as re-roofs and replacements on existing residential, multi-family, and commercial buildings across the Edmonton region. On existing buildings we assess the current deck and structure first to make sure the new system is installed on a sound base.

Proper drainage is designed into the installation from the start — building in adequate slope toward drains or scuppers, sizing and positioning drainage correctly, and detailing flashing so water is directed away from seams and edges. This matters because standing water that freezes and thaws is the leading cause of premature flat roof failure in Edmonton, so Iron Shield Roofing treats drainage as a core part of every install.

A new flat roof typically carries two kinds of coverage: a manufacturer's warranty on the roofing materials and a workmanship warranty on the installation itself. As a manufacturer-certified installer, Iron Shield Roofing installs to the specifications that keep those material warranties valid and stands behind the quality of its workmanship — we go over the specific terms for your chosen system.

Look for a contractor who is licensed, insured, and certified — ask about WCB coverage, liability insurance, safety certification such as COR, and manufacturer certification for the system being installed. Iron Shield Roofing is COR certified, WCB covered, bonded, City of Edmonton licensed, and manufacturer-certified, so your installation is backed by both proper credentials and the training to install the system correctly.
