Roof Overview – TPO Membrane

TPOTPO Membrane is a single-ply white roof membrane.  Il is the most “green” membrane because it is thinner than the others, but also because its white colour reflects the sun which prevents urban smog.

Though, this membrane requires a more careful installation to properly protect your home.  The TPO membrane is welded with hot air, thus an unqualified roofer might not provide you with a watertight result.

Our team is certified in UltraPly TPO installation by Firestone.

The Firestone UltraPly TPO membrane is guaranteed under the EnviroReady program.  This program allows the customer to turn to a green roofing techonology up to 7 years after the installation of the TPO membrane by adding either 1) a photovoltaic system (solar pannels) or 2) a garden system.

Roof Overview – Elastomeric Membrane

Elastomeric MembraneThe elastomeric membrane, also know as bilayer roofing systems, are a very resistant roofing system.  They are refered to as bilayers because an underlayer is glued full adherence to the roof structure and then, a top layer is welded to the underlayer with a torch.  The top layer being covered with thin gravel, it protects itself for sun dammages.

Though, this type of membrane is more costly than others.

the elastomeric membrane that we use (SOPRALENE® FLAM 250 AR) will provide you with a highly watertight roofing system due to its ripstop characteristics and its non-woven polyester reinforcement.

Environmentally Friendly Roof

White stones gravel roofIt is well known: the colour black attracts the heat, while the colour white reflects it.

What does this fact has to do with your roof?

Well, when the weather is very hot, especially in big cities such as Montreal, a black roof will attract the heat. When we mix this increased heat with the city’s pollution, we can end up with a smog hidding the beauty of our city and increasing the problems related with pollution.

Having a white roof in Montreal helps to prevent smog creation because it repels the heat instead of attracting it.

A

simple step can make a great change for our environment. Did you know that asphalt and gravel roofs can also be white by simply replacing the usual gravel with a white marble gravel.  See it yourself on this picture!

Roof Price Online

Dollar symbolWhy is it that I can’t find a roof price online? Can you give me the approximate price of a roof by telephone?

These questions are frequently asked by Montrealers who seek a roof redo.  Unfortunately, it is impossible to estimate the price of a roof without having a professional to see it.

Here is why.

Multiple elements make the price of a roof redo to vary, such as:

  • The size of the roof
  • Is the metal flashing to be redone?
  • How many roof ventilators do we have to change?
  • How many drains do we have to change?
  • Is there a skylight to change?
  • What is the state of the roof slope?
  • Do we have to change a roof access cover?
  • Do we have to change dryer exits?
  • What is the installation required to access the roof?

Fortunately, all our estimates are free!

Stay safe, ask for a professional.

Roof Hustlers

Some will do it out of pure greed, others will simply lack the expertise.  In both cases, you will end up with the same result: a poorly done roof that costed you a good amount of money.

Some will do it out of greed. Others will simply lack the expertise.  In both cases you will end up with the same result: a poorly done roof that cost you a good amount of money.

The roofers came, did the roof, and went back.  The leak in the room of your child stopped. Everything seems good.  In the end, the job was done and you saved almost 4 grand compared to what the other roofers charged.  What a deal! Or is it really…?

Time passes.  Two years later, with your roof worries far gone the leak comes back.  This time, it’s even bigger.  A good part of the ceiling is destroyed, the hardwood floor, the wall, and your kid’s wardrobe too.  Hastily, you grab the phone and dial the number on your roofer’s bill.  No answer.  The company that made your roof has disappeared, and so did your warranty. This kind of situation is not rare.  Many Montrealers have no other choice but to hire a new company to redo their roof as it should have been done in the first place.  In sum, they had to pay for 2 roof redoes instead of one, including the costs related to the interior damages caused by the leak.  What seemed like a deal at first ended up a financial nightmare.

Here are some examples of necessary elements that a good roofer will always do:

It is necessary to remove all existing roofs down to the wood deck before reconstructing the new roof.  Installing a roof on top of an old one will only postpone your problems.

It is necessary to adapt the slope of the roof to the drain so that the water may flow out of the roof.  Failure to do so will result in excessive accumulation of water on the roof, which will cause your roof to age prematurely as well as to increase the risks of leak inside the building.

When necessary, it is primordial to redo the wood deck and the walls before installing a new roof membrane.  Problems to the structure of the roof will necessarily result in problems related to the sealing of the roof.  A moldy wood deck will not allow the membrane to adhere properly which will result in sealing problems, and could also result in more severe problems such as a roof droop.

A safe roof is the first step to a safe house. A cheap deal might result in disappointing results.
