Rowhouses, plexes & shared roofs
Verdun, Saint-Henri and Pointe-Saint-Charles are rows of attached brick plexes and workers’ houses, with long flat roofs running from one building to the next.
When roofs are joined like that, a leak doesn’t care where the property line is. Water can come in at the neighbour’s parapet or a shared drain and show up in your ceiling, so we look at the roof as a whole before we decide what to fix.
We repair and replace flat roofs, rebuild the flashings where buildings meet, fix parapets and drains, and can work with the neighbours when a repair crosses onto their side.
We’ll find where the water actually gets in and show you. If the repair crosses onto the next building, we can explain it to your neighbour and quote both sides.
Yes, as long as the joint with the neighbouring roof is detailed properly so it stays watertight.
Yes, and on attached roofs it often makes sense: one crew, one continuous membrane and no joint to seal between you. We can quote each owner’s share separately.
Over time, yes. Standing water wears a membrane out faster and finds every weak spot. We check the drains and the slope and correct them.
Yes. Water gets in at the crack and soaks down into the brick and the wall below. We redo the cap and the flashing under it.
Bubbling or discoloured paint on the top-floor ceiling or walls is often the first sign. An inspection can also catch worn flashings and cracked caps before water gets in.
