Having milder winters are good and bad if you ask me. Why is it good if you ask; first of all there isn’t a big load of snow sitting on your roof and your furnace is not working day and night to keep your house warm. A roof that is due for a replacement isn’t capable of shrinking in cold temperatures as much as a new roof. Shingles do shrink and expand when there is a change in the temperature. During summer shingles do expand and after ten or fifteen years of expanding and shrinking causes major wear and tear. If you take a closer look at your roof , you can see the lines are starting to appear more and more before the curling begins.

If you ask why the milder winters are bad for your roof; the answer is simple. The shingles are not designed to stay under the direct heat  from the sun. Winter is a good time for them to cool of but they have no break from the sun, it will eventually start to curl up and you would need to replace your roof more often.

A year ago just before the weather got warmer we faced a wind storm that damaged a lot of homes in different parts of the town. That is a perfect example for unpredictable weather. The shingles were not ready to expand and bound properly before the wind took them for a ride. For two months straight we were doing repairs in different parts of the town. Majority of the roofs were in rough shape and they should have been replaced previous year but replacing a roof can be expensive and homeowners should be prepared for the necessary repair costs.

It is highly recommended to hire a professional roofing contractor in your area to inspect your roof before and after winter. Age of the roof does not necessarily mean that it will protect you mother nature.

We offer free roofing inspections in Ottawa, Nepean, Barrhaven, Kanata, Stittsville, Orleans and Greely Ontario.


It is not a common practice to replace a roof in cold winter months but if it is needed “yes”. If there is a major issue with your roof and did not have the budget to get it done last fall, better now than before the heavy rain begins in spring.

Shingles do freeze in winter but if its kept in a worn place prior to installation, it will make a big difference. I remember re-roofing a house in december and had all the material boomed on the roof. When we started to install and couldn’t separate the sheets apart because of the cold temperature tought me a lot about replacing roofs in winter. There are lots of details that needs to be taken to a consideration when replacing a roof in winter. For example if the pressure is too high when using an air roofing gun, it will puncture the shingle and next time there is a wind storm your roof will be waving like the ocean. It is very important to have the right pressure, just enough for the nails to be flush with the surface of the shingles. Also all the ice and water shield should be heated just enough to bound to the plywood. Caulking should be applied warm on all the exposed nails and around the vents. Cold caulking does not have the stickiness to actually seal properly. Keep caulking warm in the truck prior to applying to get better results. Before the heavy rain fall your roof should be inspected for proper bondage.

Make sure to hire a professional roofing contractor who can follow these steps.Any non insured contractors who is working in your premises is the homeowners responsibility. Be aware of the fly by contractors and protect yourself and your loved ones.

I have been installing shingles and flat roof membranes for a long time and there are many different brands of roofing products out there to choose from. They are all made from the same mixture of materials. One brand can be darker than the other or other brand may have variety of colors to choose from. I personally think that it’s not the brand of the shingles that matters. If you ask why; there are many factors involved in the life span of your roof, for example underlayment, ventilated soffit, roof vents, slope of your roof, location of your house and on and on.

You can install the identical shingles on two different houses in two different locations and the one that’s less visible to sun, better ventilated and with a better pitch will last a long time to age. On the other hand if the house is right under the sun all the time, poor ventilated and has low-pitched slope on it will get fried.

Choosing a mid range color is a key when it comes to replacing your roof. Darker colors will attract the sun and life span will be shortened. Lighter colors are in the same category but opposite reaction to the sun. Sun reflects of the brighter colors and there is still a big impact on the life span of the roof. Mid range colors are always out there but they are not flirting with the sun. Sun is a player and it will burn you down as soon as you turn around.

Always inspect your soffit to make sure it is not blocked by insulation and there is a path for the fresh air to flow. Ventilation is a must, your attic should be same temperature as the outside. Make sure according to the sqf of your attic, have enough ventilation installed.

Always hire a trusted roofing company that you can depend on. Ask family or friends for advice if you don’t know any. Search on the internet for reviews and ask for references.
