Spray foam roofing in Fort Saskatchewan covers two roof populations within a few blocks of each other. There are the old low-slope roofs over the main street, and there are large industrial roofs on the working side of the city, and they arrive at the same decision from opposite directions.
Old low-slope roofs over a main street
A downtown building of real age has usually had its roof done several times, each layer added over the last, and nobody now has a complete record of what is up there. Parapets on three sides, a shared wall with the building next door, and drainage that was reworked at some point are all normal. That makes the survey the whole job on these buildings, because the number of existing layers and their condition decide whether a recover is possible at all or whether the accumulated build-up has to come off first.
A shared parapet is somebody else's building too
On an attached main street row the parapet is frequently common, and water that gets in at that junction does not respect the property line. That turns a roof decision into a conversation with a neighbour, and it is worth having early rather than after the work is scheduled. A sprayed system has a genuine advantage at that detail, because it can be carried up and over a parapet as one continuous surface rather than terminated with a flashing that has to be maintained.
Industrial roofs a few blocks away, and what fails on them
On the working side of the city the buildings are large and simple and the roofs are full of penetrations: exhaust, make-up air, mechanical units, conduit. Every one of those is a separate detail on a membrane roof, each with its own flashing to make and maintain, and that is where these roofs leak almost without exception. A sprayed roof passes over and around all of them as one surface, which is the strongest technical argument for it on that kind of building.
Snow that arrives in November and leaves in March
Nothing melts off a Fort Saskatchewan roof mid-winter, so the load sits for months and acts as a blanket over the assembly. Anywhere the roof is warmer underneath because of a leak in the ceiling below, that snow melts at the deck and refreezes at the cold edge, which is where the ice at the perimeter of these buildings comes from. It is worth understanding as a symptom of the ceiling rather than of the roof covering.
Spray Foam Roofing Fort Saskatchewan: Common Questions
Nobody knows how many roofs are up there. Is that a problem? It is the first thing the survey settles, and it decides whether a recover works or a tear-off is needed.
Why are the leaks always at the vents and rooftop units? Every penetration is a separate detail on a membrane roof. A sprayed roof covers them as one surface.
How is a shared parapet handled in a spray foam roof? Then it belongs in the conversation early. A sprayed surface can carry over that junction continuously.
