The first thing to understand is that a roofing contractor is in the business of installing and replacing roofs. Roofing repairs are a very small part of his business, earning him the least amount of profit. In many cases, whether to replace or repair is borderline, and you can bet most roofing contractors will recommend replacement.

There are several things to consider that could affect the decision to repair or replace your roof. You must remember that no two roofs are the same. If you have damage to 30 percent or more of your roof, or if there is extensive moisture damage to the roof deck or wood deck, your entire roof may need to be replaced.

If your roof was damaged by a tornado or hurricane, then you should probably replace the entire roof. Damage often occurs that cannot be seen, so replacement is the best solution. Better safe than sorry.

Pre-existing conditions can lead to a complete roof replacement, such as inferior material, poor design, rain during installation that breeds mold, and poor installation practices.

Two indications of a major roof repair are if your home’s walls and ceilings have moisture marks and/or if the paint on your walls and ceilings is flaking or peeling.

Long, hot sunny days, wind, tree limbs, and ice can damage shingles or cause them to fail. In most cases, repairs are fairly inexpensive and easy to do. However, there is always the possibility of more serious conditions.

That’s why it’s always important to consult with a professional roofing contractor who can help you determine if there’s a significant problem.

Asphalt shingle roofs should last 15-20 years if the materials used in the initial installation were of good quality. If your roof is more than 12 years old and you are experiencing roof leak problems, you should consider replacing your roof.

If you have more than 3 layers in your roof and it’s having problems, it’s probably time to replace it.

When pressed for an answer, most reputable roofing contractors will give you an honest answer on whether to repair or replace. Always get three quotes and opinions when dealing with any contractor. Always check with the Better Business Bureau about any contractor you intend to use to make repairs.
