Commercial flat roofs are more likely to accumulate more snow and ice when it’s compared to pitched roofs. if the roof is designed with a high curb all around, it can be the main cause of the snow to park for long term rather than blow away with the wind.

Depending on the sqf of the flat roof, dept of the snow can be a real danger if you ask me. There is big difference in between powder snow and wet moist snow. It may be dry and powder right now but as soon as thaw starts the weight of the snow will multiply. We have seen in the past flat roofs collapsing due to extra weight added on by the wet snow.

It is very important to clear not all but most of it prior to thaw to avoid the structural stress and possibility of structural damage.

Roof snow and ice dams

Ottawa Roofing Blog

Winter in Ottawa Ontario can be different every year. Because there is always freezing rain in the forecast for the capital, there will be layers of snow and ice build up on your roof. It can cause structural damage because of the weight.

There are many reasons for ice damming other than freezing rain like poor ventilation, heat loss, blocked soffit or even having a low-pitched roof. It the slope of the roof is 6/12 or less, ice and water shield must be installed under neat and both sides of  the valleys. On a 4/12 pitched roof i would recommend 9 feet of ice and water shield. If your house is facing north and south than your north side is more at risk of water damage before the south side. If you ask why; south-facing side of the house always kept warm by the sun and snow will always…

The Riefa Green Roof Revolution

For some time, much of the green roofing solutions being promoted in the construction sector have been at times rather questionable as to their actual green credentials. Green roofs are frequently quoted as the saviour of our urban environment, but when faced with the reality of the broader environmental impact of the plastic trays, felt bases, and granular linings that are used in the installation process, standard green roofing does give way to some eye brow raising questions. As well-intentioned as they set out to be, standard green roofing remains flawed. The good news is that greener alternatives do exist that actually meet the expectations and ideals of the customer.

Riefa Green Roofing Solutions offers one such alternative. Riefa has been staging a revolution with a much lighter, less expensive system made from an organic and sustainable fibreboard. Once the existing roof is covered with a waterproof membrane, the

Ottawa Rooftop Snow and Ice Dam Removal 613-255-2323.

Ottawa Roofing Blog

There has been a major increase in town-home developments in the past five years in Ottawa Ontario. Mainly in Barrhaven, Kanata and Orleans Ontario from 2 to 3 story town-homes. Price for a new roof can depend on the style of the house as well as the details.

Not every home is built the same and there are townhomes as big as a single family home. Roof structure on townhomes are mainly elevated. There may or may not be any valleys, dormers, lower roofs at the front or at the back of the house. It is always recommended to replace the entire roof at once but most of the time it is a mission impossible to bring 4 to 6 homeowners agree on terms. End units are always more expensive to replace because the end units are much bigger in terms of square footage as well as the middle…

Since the last wind storm i had customers complain about other roofing companies who wants to charge 250$ for sending a service truck to an address and to perform simple roofrepairs at homeowners cost. So 250$ for the service call plus material and labor???

Would you agree to pay a roofing company 450$ to remove 3 taps and install 3 new taps of shingles to your roof? I don’t know if you are second generation rich person but paying 450$ for that is sounds like robbery to me. We offer free estimates all around town and when we do price out a job we asses the difficulty of it and amount of material is needed to complete it. I have done repairs for as low as 60$ if its only one or two taps and it’s easy to get to. Time to wake up people. Also many people are…

If you experienced a leaky winter because of all the snow and ice build up on your Ottawa home or office, maybe it is that time to reconsider a new roof.

A new roof has more advantages in the long-term when compared to repairing it once or twice a year. Repairs may or may not cost few hundred dollars but again depending on the situation it may be a lot more than you’ve expected.
Most important advantage of a new roof is that you will be worry free for a very long time if it was done right. You may have to come up with the money at once or in few months depending on the company. Always walk away from ZERO INTEREST or financing options if you ask me because you will pay thousands of dollars more if you do your math. If you have no other options…
