Our roof, like our furnace and air conditioner, require regular maintenance to work at peak efficiency. To get the most out of our roof, a semi-annual inspection can save up to 45 per cent of the cost of a roof replacement and extend the life of your roof through corrective maintenance.
Don’t wait for your home insurer to tell you to commit a roof inspection, by then it might be too late to save the existing roof and a complete roof replacement may result due to negligence. The roof’s ability to maintain a watertight seal against the elements is its’ primary job and when the roof can’t maintain a waterproof system, the longevity of the roofing system will be called into question.
Twice-a-year inspections can identify damage that has occurred due to inclement weather, rodents or tree branches that breach the surface coating. When conducting a roof inspection some factors that you should consider would be the age of the roof, general wear and tear, damage and improper insulation to name a few.
Inadequate insulation can cause heat build up in the attic that radiates through the roof structure to the shingles and in turn cause the shingles to curl and crack exposing the underside underlay to potential water leaks. Ventilation and insulation are the keys to protecting your shingles from the inside out.
Most homes have asphalt shingles that coated in granules, over time and exposure, the granules become loose and wear off. When the granules start to decay it exposes the shingle surface to the vagaries of Mother Nature that can take a toll on the shingles and reduce their overall effectiveness.
Loose shingles or missing shingles is an indication that your shingle’s tar seal is starting to go, a temporary quick fix tar reseal will certainly help it is not a permanent solution to the problem.
A roof that is buckling can trace the cause back to insufficient ventilation and attic insulation. Overheating creates moisture buildup that adversely affects the roof truss and roof decking that cause the roof to sag that is visible from the outside.
Woodpeckers, squirrels, mice, and raccoons can do damage to shingles and flashing and create holes that expose the interior to the potential water leaks. Regular inspections quickly identify these problems and the holes can sealed and capping and flashing can be replaced quickly for a fraction of the cost of a roof replacement.
Flashing around chimneys, vents and skylights is another source of potential water damage if they aren’t watertight. Caulking surrounding the vents, skylights and chimneys can shrink over time and allow water to seep into underside the roof that can cause rafters to rot or water to seep into your home.
When conducting an inspection of any or all of these elements, it is important to determine if the elements are still in good shape. For example, is the vent still straight, if is not it might need to be replaced to prevent water damage.
Your water drainage system is another important element of a roofing system and it is importance to your roofing system shouldn’t be underestimated. Eavestroughes and downspouts were designed to run water off your roof and away from your foundation.
