Roof inspection (IKO)
You won't know for certain until an experienced roofer performs a clear visual inspection of your roof.
Generally speaking, your attic should be within 5-7 degrees Celsius of the outside temperature. In the wintertime, there should be no frost in the attic. In the summertime, there should be no excessive heat in the attic. Excessive heat in the attic will speed up the deterioration of the roofing materials and decrease the life expectancy of the roof.
Some signs that you may need to replace your roof include, but are not limited to:
Your roof is a system with a number of working components. If one or more of these components is not working properly, a breakdown in the system may occur and you will more than likely experience ice build-up. Causes include:
Our experts at Custom Roofing Ltd. will explain to you in detail how our roofing system minimizes the chance of ice build-up. Briefly, the building code for eave protection is 14" inside the heated wall - your average soffit brings this close to the 3-foot mark. The standard practice for Custom Roofing Ltd. is a minimum of 6 feet of ice & water shield at the lower eaves. This effectively exceeds the building code by double. Further, Custom Roofing Ltd. covers the remainder of the roof with synthetic underlayment.
These factors contribute to why Custom Roofing Ltd. can offer the Workmanship Warranty that we do.
