Layers of felt paper and liquid tar can last a long time. Proper slope towards the drain is crucial or pooling water can lead to leaks that can never be found.

Flashing is causing leaks

If there are trees nearby, cleaning the drain filter regularly can be your first step. If the slope is designed to guide water into the eavestrough, regular cleaning is very important. Noticing air pockets (blisters) is an indication of a leak. Blisters must be cut out and sealed with plastic cement. Leaks around the drain are the most common issues with flat roofs. Sealing around the drain with plastic cement can be an option diy project.

Leaking Around the drain

Skylight flashing and exhaust vents can be problematic also. Inspecting for cracks and sealing it with plastic cement can stop the leaks. Always tie your ladder when climbing height. A professional roofing contractor is only a phone call away.

Tar has cooked up over the years

There is a small % of roofing contractors who know how to install or repair flat roofing systems in Ottawa Ontario.

Homes built around the 1980s or prior years had tar and gravel roofing systems. Back then, it was the most popular roofing systems and it was affordable. 40 years later, these roofs need to be restored to new technology systems. New roofing systems like Modified Bitumen torchon roofs are a RedSeal specialty.

FIRE PROTECTION (PROBOARD)

Finding a leak on a tar and gravel roof can be not only challenging, also it can be costly for the homeowners. In my personal experience, I always recommend for a new roof instead of trying to bandaid and old system.

180FF BASE MEMBRANE

In order to install a new roof, gravel needs to be removed off the roof, tar needs to be removed completely, and all the flashing needs to be removed. Once we are down to the bare wood deck, slope can be adjusted according to drainage that already exists and/or address the slope to prevent water pooling on the roof.

250 CAP MEMBRANE

If the slope is good, the roof deck is in good shape, and fire protection will be the first item to installed, followed by the 180ff base membrane starting from the drain of course. 180ff membrane will be folded down onto the side walls prior to installing dripedge starter metal flashing. Once the dripedge is installed and fastened with nails, everything has to be spray primed (manufacturer recommended ) for a superior seal. The next step is to install a strip of 180ff membrane on the flashing to seal the nails and flashing to the field. Now, we are ready for the Torch 250cap membrane starting from the drain.

We only use white color membrane to maximize energy efficiency and regulate the temperature inside house as well as extend the life of the roof.

There is a big difference estimating a roof by looking at it from the street or actually getting up on the roof and measuring the sq footage and the details. Getting up on the roof and measuring is called “a quote”. A quote is more preferred for you because it is accurate measurements instead of eye balling. Eye balling is an estimate where the price may change without a notice because contractor sold himself short and needs to hustle the customer.

Always request 3 roofing quotes when it comes to replacing your Ottawa home, office or commercial building from few local roofing companies. Cheap does not mean good, expensive doesn’t mean good either. The entire concept of getting 3 quotes is to identify the price difference between all and types of material being offered.

Material being used in the current roofing industry are very similar and only thing that really needs to be looked at is the amount of “ice and water shield”, maximum roof vents and the felt paper. Ice and water shield must be applied at least 6 feet from the eavestroughs and the rest of the roof needs to be covered by #15 felt paper or higher grade. Installing ice and water shield and the felt paper must be done by hand. 1 1/4 hand nails are my preference when it comes to hand banging. If there are any valleys, ice and water shield must be installed under neat the metal valley prior the metal valley itself. Valleys are known for ice damming and that’s why we use ice and water shield. A roofing gun can be used to install the shingles only as long as proper dept is set on every gun that is being used on that specific roof.

These are the most important details to look for when it comes to replacing a shingle roof in Ottawa Ontario. We offer free roofing quotes and estimates in Ottawa for residential pitched roofing, residential flat roofing, commercial shingle roofing and commercial flat roofing sales, installations, repairs and services.ImageImageImage

Read the entry here published on waterproofing of horizontal surfaces , flat roofs and terraces passable. The flat roof is characteristic of the modern house . Although there are modern chalet style houses with sloping roofs, the change in architecture leading to flat roofs and its use was effective as modern house design and modern buildings in the twentieth century.

Actually, a flat roof is not strictly horizontal: if not, the water will not slip out. They are named for the average slope of a flat roof (between 1 and 3 inches per foot of horizontal development) is significantly lower than that of a tiled roof: it can range from 0.30 meters to at least one meter Ceiling horizontal development. It is therefore more likely to heavy rain water from collecting in a ceiling more than one inclined plane. And so, the chances of leaks. Especially if the ceiling is not well resolved encounters with wall’s insulation (babetas calls). Or if they were not well constructed seams or vents in the funnels through which the water will drain.

If it snows, the choice is one: in these cases the sloped ceiling is imposed. Even if possible, it is desirable that the ceiling as simple as possible. This prevents the breaks-called valleys, and hip lines-which are the weak points of a sloping roof.
