What is the Primary Purpose of Shingles and Roof Coverings ?
Shingles are engineered to shed water off the roof surface and are the protective covering for all the materials beneath them. Many shingles today, installed correctly with proper ventilation, can perform for 30 years or more with great efficiency. However, if incorrectly installed along with other components of the roofing system, including improper ventilation, inadequate substrate, missing underlayment or flashings, premature shingle degradation and subsequent roofing system failure could occur much sooner, causing costly repairs in the future.
How Do I know If I Need To Repair or Replace My Shingles ?
One indication that you need to replace or repair your roof is to take a look in your eavestrough. The rain gutter will have granules of asphalt that will indicate that your shingles have started to ‘bald’. Any type of moss growth is another sign that your roof might need replacing. Of course, if you have any leaks inside your home, discoloration or spots on your ceiling, that is an indication that moisture is seeping or dripping in.
In the spring, missing shingles are a common roofing problem. The shingles may have been poorly installed or come loose because of high winds, ice and snow damage and other weather exposure. Missing shingles should be replaced by a professional to ensure the roof’s integrity remains intact and no leaking occurs.
Improperly installed, degraded, damaged and missing shingles are the primary causes for roof leaks. This doesn’t necessarily mean you have to replace your roof. Cost effective repairs can be made to stop the leaks and extend and preserve the life of the roof.
Why Have My Shingles not Lasted as Long as Expected ?
Lack of or an improperly ventilated roof and attic are often one of the biggest causes of premature roof failure. It’s no longer good enough just to have roof vents. Ventilation needs to be designed to have a balance of intake and exhaust; a continues airflow evenly distributed on the entire underside of the roof deck to help keep the shingle surface cooler in the summer and to prevent moisture build up in the winter. This causes the shingles to fail causing premature aging including curling and balding (granular loss).
ICE DAMS WARNING
Ice dams are a common sight in Canada’s long cold winters, but is this normal?
Ice dams can be sign of serious problems with your roof system.
They can cause damage both in your roof, inside your home, and anything it falls on.
HOW DO ICE DAMS FORM ?
Did you know that more than 30% of heat in the house is lost through the roof?
As heat escapes from the living space through the ceiling insulation, the attic space gets warm enough to melt the bottom layers of snow on top of the roof.
When the water reaches the frigid air on the gutters, it freezes and creates ice dams, which only grow as the melting continues.
WHAT PROBLEMS CAN ICE DAMS CAUSE ?
They can cause The water to leak under the shingles
The water can cause leakage in the attic, soffit and exterior wall.
As the ice dams grow the roof, they can causewater backing up and leaking into the house causing water damage to walls, ceiling, floors, insulation and other areas.
Ice dam formation can get very heavy and cause eavestrough falling, property damage, and even structural collapse.
Icicle falling and ice formation on the ground can be a real safety hazard for the occupants.
The water can damage the electrical wire, which can lead to a serious risk of electrical shock and possibility of fire.
They can also cause unwanted moisture and resultant mold, Whic can cause serious respiratory problems for the occupants
HOW TO PREVENT ICE DAMS ?
Most of the heat loss through the ceiling is caused from the lack of insulation in the ceiling and attic, around chimney openings or electrical fixtures.
Ventilate the attic through the vented soffit, allowing the heat to escape from ridged vent, roof vent or gable vents.
Insulate the living space well to prevent heat loss through the ceiling.
Insulate and seal the small light fixtures openings or other small openings in the attic area.
Installing heating cables at the edge of the roof and leaf guards on eavestrough.
