To obtain maximum life from your asphalt shingle roof:

· Keep trees trimmed to prevent damage to the roof surface from branches or falling limbs.

· Check the roof surface annually for obvious damage, lifted or worn shingles. Pay particular attention to valley areas and flashings.· Have missing or damaged shingles promptly replaced.

· Periodically check the underside of the roof for signs of leakage or damage, especially around vent pipes and chimneys. Also look for any signs of mildew or mold, which may be associated with roof leakage or ventilation problems.

· Maintain good ventilation in the attic even in winter months. Poor attic ventilation can cause damage to a roof structure. Additional vents or an automatic vent fan may be required.

· In areas with heavy snowfall and subfreezing temperatures, be alert for ice dams which form along the eaves. Ice dams can cause water damage to the interior ceilings and walls.

If isolated portions of a roof show some wear, or if storm damage occurs, repairs can normally be accomplished without much difficulty. But regardless of the type of materials used, eventually all roofing will require replacement. If it is badly worn or just suffering from overall old age, limited repairs won't practically extend its service life.

When re-roofing, it may be possible to lay the new shingles over the old one, which can avoid the labor expense and mess of removing the old covering. Most roof framing is designed to withstand the weight of two layers of shingles. However, actual roofing conditions, roof framing conditions, and local practices and regulations will have a bearing on the method of re-roofing.
