Should I Repair or Replace My Roof?

Residential Roofing, Roofing Repair, Roofing Replacement

No matter how sturdy, sooner or later, any roofing system will suffer some damage. Depending on the extent of damage, a repair or replacement may be on the cards.

Replacing the roof of your Dallas home is a major expense. We know! Though it is not cheap, a new, high-quality roof can prove to be a worthwhile investment in the long run as it not only helps you avoid expensive repairs but adds value to your home too.

Are you still confused?

Continue reading to figure out if you should go ahead with a complete tear-off or if just adding a few shingles will do the job just fine.

Is the condition of your roof bad?

If your roof is missing a few shingles or has a leak, you can probably have the roof repaired. That said, some problems necessitate a new roof. For example, while it is easy to address one leak, multiple leaks indicate that your shingles are too old and need to be replaced as soon as possible. Sagging deck or frame, granules gathered in the gutter, mold growth on shingles, and cracked, split, curling or missing shingles are other signs that your roof might need an update.


Note that in some cases, a residential roof replacement in Dallas, TX, can be less expensive than having to do the repairs on a routine basis. Even more important, the damage it is preventing from occurring can save you money over time.

Has your roof reached the end of its lifespan?

The age of your roof is another factor to consider. As much as we would like it to, roofing does not last forever. Most asphalt shingle roofs will last 15 to 20 years before they need to be replaced, while new types of GAF asphalt shingles can last up to 30 years if maintained well. Wood shakes last about 30 years as well. However, they are more susceptible to moisture damage and mold growth over time. Metal roofing shingles and slate roofs can both last over 50 years (though some slate roofs can last 100+ years!)

If your roof is reaching the end of its lifespan and you notice major problems related to the roof’s condition, you need a new roof. However, if the roof is not that old, going for residential roof repairs in Dallas, TX, might be the best option, especially if the warranty is still in effect. If that is the case, contact the roofing manufacturer to find out how to proceed.

Does the new roof go over the old roof?

If you decide that replacing your roof is the best option, you must then decide if you want to have a new roof placed over the old one or if you want the old roof torn off and replaced with a new one.

If your roof is old but structurally intact, it is usually a good idea to have the new roof placed on top of the old one. This is a cost-effective and less time-consuming alternative to having the old roof torn off first. Putting an additional layer of shingles over your roof also means that you are solidifying your preventative measures against leaks. On the other hand, if your roof has multiple leaks and already has several layers, you might need a completely new roof. There are also city codes in place regarding the number of layers permitted. In most areas, the maximum number of layers is three. Check with us to learn all about the roofing codes in Dallas, TX.

The importance of routine roof maintenance.

Performing routine inspections, resealing the flashing, maintaining proper attic ventilation, ensuring there is no standing water in the drainage system and trimming trees on your property are all maintenance tasks that you can do to increase the lifespan of your roof and prevent expensive repairs and an untimely replacement in the first place.

Should you go DIY or hire a professional?

Are you toying with the idea of doing the roof repairs or replacement yourself to save some money?

While you will find plenty of information online about every type of roof repair and replacement project, roofing tasks are ALWAYS best left to professional roofing contractors in Dallas, TX. There are many reasons why:

  • For one, there is always the risk of injuries. Roof replacement is dangerous work. There are many hazards to deal with, including heights, sloping surfaces, weather, and powerful tools. Without the right tools and safety precautions, you could suffer a slip and fall injury.
  • As a DIY homeowner, you lack the “eye” of a professional contractor, so you may be unable to identify non-visible yet significant damage on the roof that may incur extra costs down the road to get fixed.
  • With little to no roofing experience, it will also take you much longer to get the job done (if at all). Even if you manage to do it somehow, the quality of work is bound to be below-par. Again, this will result in much more expensive repairs down the line than what you are saving by not hiring a professional.


Installing a new roof on your Dallas home is a sizable investment, so you need to be sure that you are using your money wisely. Before you go the route of replacement, refer to the points mentioned above. Doing so will help you decide if you should repair your roof or replace it entirely.
