The structural integrity of a roof is one of the most important parts of a home inspection. It is so important that it can kill a deal to sell a home due to the expense involved with roof repairs. A roof inspection is part of a regular home inspection, however if a there is a possibility of trouble a roofing expert will need to be called in to give a thorough roof inspection.
A roof inspection is done to determine a roofs structural integrity, its expected lifespan, and when it may have to be replaced. Roof inspectors will not have to pull up shingles to do a detailed roof inspection. They will use an infrared thermograph to determine if moisture penetration is suspected. The roof covering is visually assessed, as are the fascias, gutters, soffits and flashings. In addition the interior walls and ceilings are inspected to check for signs of water infiltration. A report on the roof inspector’s findings is written detailing potential problem areas, and suggested maintenance and repairs.
When performing a roof inspection, the inspector will have a different checklist to go through depending if the roof is sloped or flat. Sloped roofs generally have a shingle covering made of asphalt, wood, or slate. They are normally flat, and rectangular, with the rows overlapping. The most common covering is a fiberglass asphalt shingle due to its cost and relative durability. During a roof inspection shingles will be checked to see if they are cracked, curled buckled or missing. Modern flat roofs are covered with a rubber membrane that is applied as a whole sheet whenever possible. They are bonded to the roof surface to keep it from being damaged by wind. The checklist for a flat roof inspection would include an inspection for punctures, cracks, blisters and ponding.
With proper maintenance, and an annual roof inspection, you will not have to worry about rain, snow or wind damaging your home.
