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.

We offer commercial and industrial rooftop snow removal in Ottawa and region. Give us a call or send us an email regarding your questions or inquiries.

Skylights can be the best option to brighten up any room or living space that is consuming electricity during daytime. Using the mother nature to bring in daylight can save you money in the long run no doubt.

Only problem with skylights is that if the roof is being replaced, skylight should be replaced at the same time to avoid problems in the future. If the skylight gets pried or moved a bit just to get the old shingles out, it can definitely cause leaks not today but eventually. I’ve done many skylight repairs on newer roofs just because of that reason. We can only caulk around the skylight itself or around the glass to stop the leak. These repairs are temporary solutions and it can get pricy slowly but surely. If you spend 250$ every year on repairs, you can have a new skylight installed for the same amount in 3 to 4 years. We are not talking about the drywall repairs or the paint job that is needed to complete the repairs.

Skylight leaks are not always visible to a naked eye. It can rot the plywood around it slowly and this can be a structural issue if not taking care of. In some cases mold can be found just because of the duration of the leak that was not noticed.

If a skylight is leaking, there can be 2 reasons a) it is not flashed properly b) seal on the glass is cooked under the sun for all those years. Temporary option is to repair it so that the leak stops. Permanent solution is to replace the skylight and get it over with. A new skylight comes with 10, 15 or 20 years warranty depending on the make and model as well as the company who is installing it. Always shop around and get multiple quotes from 3 different companies to compare. Cheap does not mean good, expensive does not mean any better either. Look for a reasonable price somewhere in between.

It’s not the shingles that go bad every so often, it’s the improper intake and exhaust system that is not performing like it supposed to. If the temperature in your attic is much different from outside, that is a perfect sign.

An attic that is not venting properly could cause many problems during summer and winter to your roof and to your pocket if you ask me. Lack of ventilation causes ice damming and condensation during winter months and it can get ugly. During summer months your attic will act like a furnace cooking the certain areas of your home. Your roof shingles are always under the sun and it is designed to expand and shrink depending on the temperature. When there is lack of ventilation that can be caused by improper intake system which is referred to your soffit that is designed to allow the fresh air to enter your attic and balance the temperature.

Anyone can replace a roof but not everyone is willing to make your roofing system to perform like it should. Many times the homeowners would think that we are trying to up sell the product. Some homeowners they actually do their own research and agree with the report that we reported to correct the existing issues. Other homeowners keep experiencing the same problem few years in a row after spending a ton of money on ice and snow removal, drywall, painting, new roof etc…… Once they come to their senses, it is already too late but never to late to fix a simple problem to save money in the long run.

Listen to our advice, it is free. do a little research, don’t get 10 quotes and confuse yourself. Pick up the phone and call us about your concern and we will be more than happy to answer any questions you may have. We offer free quotes and estimates for roofing, siding, soffit, fascia, gutters, foundations repairs and snow removal services.

There are lots of older homes in Ottawa Ontario that does not have significant ventilated soffit installed to increase the fresh air flow into the attic. Majority of the older homes did not come with that feature and those homeowners replace the roof way more often than they should.

Roof vents are designed to help all the fumes, hot air from your attic to escape so that the temperature of your attic is same or similar to outside. In order for the roof vents to work properly it requires fresh air to enter from the soffit. When there is no intake/fresh air entering the attic ventilation process is very slow maybe even non. You can install as many vents as you like but it requires fresh air to create a force to complete a cycle.

During winter months it is very easy to point out which house does not have proper air circulation just by looking at the ice dams. When the snow covers the vents on your roof it suffocates your attic and that causes condensation, forces the hot air to exit from the soffit instead of the roof vent itself. Hot fumes exiting from the soffit creates a thaw action daytime and allows it to freeze overnight. After few weeks of that will give you a massive ice dam that will form along the eavestrough and it will work its way along the metal valley. It can get messy once this ice starts to melt and cause major water damage to the houses.
It is not a very big job to do but there are only certain roofing companies who will be able address that issue. Many roofing companies would want to get paid for removing ice dams instead of fixing the lack of air balance. We offer residential and commercial soffit and fascia sales, installations, repairs and services in greater Ottawa region. We also do offer free quotes and estimates to potential customers who is experiencing that types of problems.

It can be frustrating when the closing date is coming up and not sure if the roof will perform as it supposed to. When it comes to a structure of a house or building the most important key players are the roof and the foundation.
If the foundation is in good standing and no moisture marks or leaks it is a good sign. If there are damp sections or visible cracks, it can be a potential problem eventually. I am not sure when the building code has changed about the waterproofing membrane against the foundation walls and whipping tile systems but if your house has water proofing membrane it is a good thing. If there isn’t a waterproofing membrane against the foundation, i would have the foundation walls inspected very closely because it will cost you tens and thousands to have it repaired properly. If there are minor cracks on the inside foundation walls, that can be injected with liquid expanding epoxy and have it fixed.

The roof may look in okay shape from 30 or 40 feet but there may be cracks, lack of underlayment or ventilation, lack of insulation or even shingles that are completely bone dry. An average roof repair can cost you anywhere from 250? and up depending on the roofing company you hire. Cost of replacing a roof is determined by the difficulty level, total square footage and how many valleys and hips. Installing proper ice and water shield and sealing the entire roof with tar/felt paper is a step before installing the actual shingles. It’s not about the name or brand of the product, how it has been prepped and how the shingles has been installed is the most important.

Did somebody say winter? Yes you heard it right winter. It is that time of year cleaning the front and back yard few times until there is no more leaves left to rake.

You don’t necessarily need to be living beside a lot of trees but the wind has its own method of drifting. Cleaning around the house gives every home a fresh and clean start when the spring is knocking at the door. But before we go to fast, we need to make it thru the winter first. It takes a lot of dedication to take all the necessary steps to protect yourself and your loved ones from the cold winter days. For starters make sure your hydro and natural gas bills are paid up to date for any surprise delays during cold days. Your roof is in good shape and has been inspected by a professional roofing company. Any branch that is leaning towards your roof is a potential danger so trim it down. All the gutters are free from leaves, debris and maybe tennis balls. It may sound strange but I’ve seen it too many times. A clogged drain is a first element of a massive ice dam that could destroy your home and cost you a chunk. Make sure all the drains are functioning and water is being guided “away” from your foundation.

If you have a low-pitched roof that is facing north, be sure to keep an eye on it because it can get messy especially when the thaw begins. Roof rakes are good to have but always hire insured and experienced roofing companies to perform the risky stuff, don’t take a chance. If you notice a leak, call your local roofing company to remove all the snow and ice off the roof.

If you are located in the greater Ottawa and have a question or concern about your roof, siding, foundation or snow removal, feel free to send us an email and we will be more than happy to assist you.

One of the consequences of not cleaning the gutters is that leaves & such accumulate. This forms humus, a precursor to soil. Plants like this. We even have plants growing on our roof valleys. I need to get up there one of these days. (Photo credit: Wikipedia)

Lets start of with the common problems that is caused by rain when there is no gutters guiding the rain water away from your home. Normally is starts working its way along the foundation and causing cracks and damage along the foundation walls. Older home are more at risk because of the older structures did not come with waterproofing membrane  like the newer homes. Foundation cracks and shifting in the foundation are few of the problems that is caused by water damage that could have been driven away from the foundation if there was proper gutters were installed in time.

It doesn’t only cause damage to your foundation it also takes life away from your shingles if you have an upper and lower section of the roof. Metal valleys are installed along the dormers to drive the water off the roof. If the valleys are facing right over a  lower roof, chances are lower roof will age way before the main roof itself. Also it is common to see drain pipes that are installed on the lower roof was not extended and where the water was gushing caused discoloration and premature ware. It is highly recommended to extend all the drain pipes in to lower gutters to eliminate similar problem in the future.

When it comes to gutter systems there is nothing like seemless gutters. Sectional gutters are okay to but it doesn’t take very long for sectional to start dripping where the joints are. If you are planning to get gutters installed around your roof, do it right the first time.

Clean your gutters twice a year before and after winter to allow water to flow.
