Roof replacement is one of the most expensive home repairs. It can be difficult to determine if your home requires roof repair or a completely new roof. Where possible, consult McKay Roofing in Lanark regarding your roof repair needs. There are a number of factors that can help guide homeowners on whether they need a new roof.
Age of the Roof
The asphalt shingled roof will last about 15 to 20 years whereas the GAF asphalt roof shingles last for more than 30 years when well maintained. You will be required to replace the roof if it has several leaks and is about 15 years old.
Number of Roof Layers
If your roof has several layers and is leaking, you will require a completely new roof. McKay Roofing and other roofing experts refer to this as a complete tear off. All the layers of the roof will be torn off and new wood framing installed. Then, new shingles will be installed.
City roofing codes are strict with the permitted number of roof layers. The maximum permitted layers of roofing is three but may differ depending on the roofing codes in your area.
Missing or Torn Shingles
Damaged, missing or torn shingles are most of the time a sign of other roof problems. Poor roof ventilation may cause a peeling of shingles due to warm air escaping through the roof. The warm air will lead to moisture forming under the shingles and making them peel. The situation can be salvaged before a new roof is required by ensuring that there are enough outtake and intake attic and roof vents.
Extreme Weather Conditions
Extreme weather such as hurricanes and tornadoes may cause roof damage that is irreparable. Sometimes, structural damage to the roof cannot always be seen. Consult McKay Roofing to help determine if you will require a new roof.
If your roof has major problems even before it is 15 years old, the design of the roof was faulty or improper materials were used. Check with the roofing company that installed your roof for warranties for the material used and even warranties that cover labor.
A Condition of Interior Walls
Sometimes, the condition of interior walls that touch the roof may provide clues about what is happening. Heavy moisture marks and significant loss of paint on the interior walls as well as the ceiling are signs of major leaks from the roof. Where there is safe access to the attic, climb up to check for moisture and to inspect the roof.
