When done right, Roof replacement can significantly increase your home’s weather protection, curb appeal and overall value. Since it’s a major project, you must carefully prepare for it. It’s essential to do your research and work with a reputable residential roofing contractor. 

Be sure to avoid these 12 common mistakes for a successful roofing project.

1. Trying to Do the Job Yourself

Roof repairs and replacement are always best done by experienced contractors. These jobs are not as simple as they seem and can risk your safety. Professionals have the right tools, appropriate training and proper safety equipment. 

You could get hurt or accidentally damage other parts of your home if you attempt to replace a roof yourself. When you make mistakes during installation, your roof might not last long. By hiring pros, you’ll have peace of mind that your new roof will protect your house for years to come. 

2. Not Researching Your Roofer

The outcome of your project is in the hands of your contractor. That’s why you should do your research before hiring one. Experts strongly recommend obtaining at least three estimates from different companies. Ideally, you should choose a local contractor since they are easier to reach if you encounter issues during and after your project. 

Make a list of roofers that specialize in your preferred Material. You can ask your family and friends for referrals or look for nearby residential roofing companies online. Run background checks, read reviews, ask for references and look at portfolios. Don’t forget to ask for proof of license and insurance. Consider the experience of each candidate and the brands they work with. 

3. Installing New Materials Over the Old Roof

When it’s time to get a new roof, you can choose between an overlay and a complete tear-off. An overlay involves installing new shingles over the existing roof. On the other hand, during a tear-off, your contractor will remove the existing materials before installing the new ones. 

A tear-off allows professionals to catch and fix underlying issues that can compromise the longevity of your new roof. For instance, your contractor might discover that the decking has damage once the old shingles are gone. They would have to install a new decking to ensure your roof lasts long and remains durable.  

4. Not Having a Written Contract

Whether planning a residential or commercial roofing project, you must have a signed written contract before the construction begins. This legally binding document should contain all your project’s details, such as the expected work and material specifications. It ensures you and your contractor are on the same page. Never sign a contract unless you fully understand all of its contents. Don’t hesitate to let your roofer know if you have concerns or questions. 

5. Skimping on Materials

Roof replacement can involve substantial costs, so it isn’t surprising for homeowners to look for ways to save on their projects. While price matters, you should also consider quality when selecting materials. Substandard products cost less but might require replacement after just a few years. 

It always pays to invest in the best quality materials within your budget. Furthermore, you should factor in your climate when making a selection. Another thing that should influence your decision is your home’s architectural style. The right roofing option can elevate the look of your humble abode. 

6. Failing to Consider Energy Efficiency

Are you looking for ways to save on your energy costs? If so, look for materials that excel in energy efficiency, such as metal roofing. Reflective asphalt shingles can also reduce utility costs by reflecting sunlight and preventing heat from traveling indoors. These options will prevent your HVAC system from working too hard, lowering utility bills. 

7. Not Considering Roof Warranties

Before purchasing roofing materials or hiring a contractor, you must consider warranties. They will protect your investment against manufacturing defects and poor craftsmanship. Hire a roofer that offers both material and workmanship warranties. Contractors who are confident in their skills and the products they use will not think twice about providing comprehensive warranties. 

8. Overlooking Attic Insulation and Ventilation

Adequate attic insulation and ventilation are vital to a long-lasting roofing system. Insulation can keep the heat or cold out, helping maintain the comfort of your living space. Ventilation keeps your attic from being excessively warm and humid, preventing mold growth and early deterioration of roofing components. These components are necessary to maintain moderate attic temperatures in winter, reducing the likelihood of ice dams. 

9. Not Investing in Quality Underlayment

You’ll find underlayment between the shingles and the decking or sheathing. It’s usually made from OSB or plywood and is directly attached to the decking. This component creates an extra layer of protection against wind, rain, snow and other outdoor elements. When replacing your roof, be sure to choose a high-quality underlayment that meets your local building codes. 

10. Not Obtaining Permits

Permits can ensure construction projects adhere to local building codes. Whether or not you need them depends on how extensive a residential or commercial roofing project is. You could pay hefty fines if you start the work without the necessary permits. A local roofer would know which documents you must secure before construction. 

11. Not Considering the Condition of Your Gutters

Gutters protect your roof and the rest of your home from water damage. If your current ones are in poor shape, you must have them replaced. An efficient gutter system will divert rainwater from your home, preventing basement flooding and foundation issues.  

12. Not Preparing Your Home

Roof replacement can involve a lot of noise and mess. A reputable contractor will take the necessary steps to safeguard other areas of your property. However, you must still prepare your indoor spaces for construction and notify your neighbors about your project’s schedule. 

Removing outdoor furniture and decor will make your roof more accessible to workers. In addition, your walls can vibrate due to all the hammering, especially on the upper floors. It’s best to remove items on the wall that could fall during the roof replacement. Do you use your attic for storage? If so, you should temporarily relocate breakable items and cover things that are too large or heavy to carry. 

Even the best materials can fail early when not handled and installed correctly. It’s why Deschutes Roofing works with industry leaders and strives to deliver superior craftsmanship.
