Tear off

If any of the following are true, a complete tear-off of the existing roof system should be considered.

Too many layers – If a roof has more than one layer of roofing, the roof should be torn off. In most cases this is a code requirement. Codes rarely permit more than two layers of roofing. To determine this, all you need to do is contact your local Residential and Commercial Roofing Company. 
Bad decking - if spongy areas are noticed when walking on a roof, or if you see sags between the rafters or trusses, there's a chance that some of the roof deck may be deteriorating or be damaged. Deterioration can be attributed to dry rot or delamination of the plies in the plywood due to glue failure. Dry rot is wood rot caused by certain types of fungi and if it isn't taken care of, it can spread. If there is suspicion of bad decking, then a full tear off should seriously be considered. 
Ice dams - ice dams can be a big problem. In areas where there the average January temperature can be below 30° F, and no ice and water protection membrane is present on a roof, then a full tear off should be considered. Twenty year old buildings with no ice and water protection and no prior problems, can suddenly experience thousands of dollars in damage when a freak cold front hits. For more information on ice dams.
Incompatible shingles - if a heavy weight architectural style shingle is used to cover a light weight strip shingle such as 3-tabs, then the roof will look good. However, if a light weight shingle is used to cover a heavy weight shingle, the light weight shingles have a tendency to show all the bumps and ridges (called telegraphing) and won't look good. 
Existing roof is in poor condition - if the existing roof is in really poor shape, such as tabs being severely curled or if the rows are crooked, then complete tear off and replacment should be considered. 
Shorter Life Span There is no known documented research, but most roofing professionals agree that with an overlay, the average lifespan of the shingles will be shortened by about 10%-20%.

Repairs

Emergency repairs may be required after severe weather because leakage into a building can occur at any time (nights, holidays, weekends, etc.). Caution: It is generally not advisable to attempt roof repairs until after the severe weather has ceased, due to the danger of high winds and the possibility of a lightning strike. Caution should be exercised when inspecting a roof after there has been severe weather, or when there is suspect damage to the roofing assembly, because storm damage may have left the roof in a hazardous condition. Emergency repair procedures should be as simple as possible so they may be performed safely by non-roofing professionals. These repairs should be considered temporary. 
Locate the source of a leakIn attempting to determine the source of a leak, locate the point on the roof surface above the area of leakage in the building interior. From this point, first check the condition of rooftop mechanical equipment, then check all flashings at terminations and penetrations. Then check the membrane surface for cuts, splits, or punctures. Finally, check the seams (laps) in the roofing membrane. Caulk or patch area. 

Typical Causes of Roof Problems

A. Lack of Maintenance
The failure to find and correct minor roof deterioration in the earliest stages is probably the greatest cause of premature roof problems. This is particularly true of roofing materials applied on relatively low-sloped roofs. 
B. Weathering 
All roofing materials deteriorate from exposure to the weather at rates determined largely by the kind of material and the conditions of exposure. In general, inorganic roofing materials tend to deteriorate less rapidly from exposure than organic roofing materials. All types of roofing materials may be damaged by hail. Exposure to air pollutants and industrial or salt-laden atmospheres may accelerate the deterioration process of some roofing materials. 
C. Wind Damage
Roofing materials are subject to damage from strong winds and flying debris. Generally, roofs are not designed to withstand winds of hurricane and tornado intensity. However, roofs may also be damaged by winds of moderate intensity, with gust that may reach 50 to 75 miles per hour. The primary cause of wind damage is from the partial vacuum created by wind blowing over the edge of the roof. Nature tries to neutralize the low-pressure area by bringing in air from a higher pressure area, usually from inside the building. This air pushes up on the bottom side of the roof assembly and, over time, loosens fasteners and breaks the adhesion making the roof susceptible to damage from the next moderate or strong wind. To counteract the effects of wind-uplift forces, the roofing and insulation should be adequately fastened to the roof deck, and a securely-fastened perimeter detail should be provided. 
D. Improper Design 
Troublesome and costly roofing problems are often the result of faulty initial design of the roof system. Design deficiencies are costly to correct, and usually can only be corrected during roof replacement. However, unless design deficiencies are discovered and corrected during roof repair or re-roofing, the problems relating to them most likely will recur. Some examples of faulty design are: Weak roof structures that deflect excessively under load, causing splitting of the roof membrane Inadequate roof slope, sagging roof structure, or insufficient number or location of drains, resulting in ponding water 
Inadequate provision for expansion and contraction at changes in deck material or direction, causing membrane splits. Incompatible roof materials - i.e. the use of asphalt to adhere a torch-on material (APP). 
E. Flashing Failures 
The function of flashings is to provide a watertight junction between roofing materials and roof projections or other parts of the structure, and between roof sections. Flashings should be designed to furnish service for at least as long as the materials used in the field of the roof. Flashings are the most vulnerable part of any roof. Their importance and the importance of maintaining them properly cannot be overemphasized. 
Many early roof problems are actually flashing problems. Often, repairing the flashings or providing new flashings is all that is needed to make the roof watertight again. Most flashing problems result from inadequate flashing design or faulty construction. Many flashing problems can be reduced or eliminated by careful examination by competent inspectors during roof installation, and by regularly scheduled inspection and maintenance. In many instances, leaks occur at flashings where there are no flashing defects. These leaks may be the result of open joints in a masonry wall or coping cap, which permits water to enter behind the flashings and into the building. This problem may be eliminated by "through-wall" flashings. 

Reroofs  covering existing shingles with new shingles.
reroofs are only permitted with a heavier shingle over a lighter shingle with a good nailing service. Reroofs are not allowed on curling or heavily deteriorated shingles.
