Contrary to a common misconception, a roof does not necessarily last as long as its warranty. Depending on the quality of materials used, a roof can last anywhere from 20 to 50 years. However, you must view your roof not just as the shingles you see but rather as a complete roofing system that includes a deck, proper underlayment, insulation, flashings and attic ventilation. If you only replace your roof shingles, the chance that you will encounter more problems down the road is likely, and your roof will eventually fail sooner than it should.
In most cases we attend to, property owners only discover problems with their roof systems after a leak or serious damage. However, by this time, it may be too late, and the repair job might cost more than it would have if the problem were discovered earlier.
Therefore, regular inspections can help you uncover the following visible signs before they become serious problems.
Not always. There are many reasons why a roof may be leaking. It could be that a section of the roof is damaged or that flashings have come loose. In these cases, you do not necessarily need a complete replacement. However, a complete roof failure due to improper choice of materials, faulty installation, or the roof system being inappropriate for the building is generally irreversible and might require a complete roof replacement.
Ice dams are generally formed by the continual thawing and refreezing of melting snow due to weather conditions. During this time, large masses of ice develop on the roof as snow melts. The melted water flows under the snow above and refreezes at the roof’s edge. As additional snow melts, it forms pools of water that gradually back up the roof, often getting under the shingles and leaking into the house.
To avoid ice dams:
Ventilation plays a crucial part in the functionality and longevity of a shingle. Temperature fluctuations from summer to winter accelerate aging on your asphalt roofing shingles. However, proper air circulation reduces the chances of leaking, distortion, blistering, wood rotting, curling, wet insulation and other potential problems regardless of the weather outside.
Additionally, you need to prove adequate ventilation in order to validate the manufacturer’s warranty on the shingles. Locally, the National Building Code prescribes the minimum requirements that must be observed.
