Spray foam roofing in Rocky Mountain House is a recover system, sprayed over the existing low-slope roof and finished with a protective coating. It ends up as one continuous surface, and on a commercial building in this district that matters for a reason worth stating plainly.
A flat roof in a district where everything else is steep
Almost every house and outbuilding around here has a steep roof, because that is what people build where snow is serious. The commercial stock does not. Shops, retail units and light industrial buildings have low-slope roofs, which means they hold what falls on them for months while everything around them sheds. That is the fundamental difference between a commercial roof in this town and every other roof its owner looks at, and it is why the drainage and the surface both have to be right.
Parapets, drains and the places snow piles up
Snow does not sit evenly. It piles against parapets, at changes of level, behind rooftop units and in the lee of anything standing above the roof, and those are the places that stay loaded longest and melt last. The survey looks at exactly those spots, because they are where standing water sits and where a seam in a jointed system will eventually give way. Where the fall toward a drain has gone wrong, foam can rebuild that slope on the way through, which very few roof systems can do without structural work.
Recovering a roof over a building nobody can empty
A recover leaves the existing roof in place while the new system goes on above it, so the building is never open and nothing inside has to move. For a Rocky Mountain House retailer or shop with no quiet season, that is the practical argument rather than the price. All the work happens from above, and the constraint that moves a date is weather rather than the tenant.
What the recoat cycle actually asks of an owner
The coating is the part that wears and it is renewed on a cycle. That is worth being clear about at the start, because it changes what is being bought. This is not a roof that is fitted and forgotten, it is one that gets inspected and recoated, and in exchange it does not arrive at a point where the whole assembly has to come off. For an owner budgeting in years rather than reacting to failures, that is generally the better arrangement, and it should be said before the sale rather than after.
Spray Foam Roofing Rocky Mountain House: Common Questions
Does the old roof come off? Usually not. It stays in place as protection unless the survey finds the assembly is wet.
Can the slope be corrected where water sits every spring? That is a fall problem. Foam can rebuild the slope toward the drain on the way through.
What does it need afterwards? Inspection and recoating on a cycle. It is budgeted rather than discovered.
