Re-Roofing Services in Portland

Residential & Commercial Services

Your property’s roof is its first line of defense against the elements. It protects your home or business from rain, wind, snow, and extreme temperatures. Over time, however, roofs can become damaged and need to be repaired or replaced. When this happens, it’s important to choose a reliable and experienced re-roofing service.

Rainy City Roofing is your go-to re-roofing Portland experts. With over 30 years of combined experience among our roofing contractors, we have the knowledge and skills to handle any re-roofing project. Whether your property has a flat, sloped, or metal roof, we have the expertise to provide high-quality and durable re-roofing options.

When Is Re-Roofing Necessary?

Re-roofing is the process of adding a new layer of shingle on top of an existing one. This is different from complete roof replacement, where the old roof is completely removed first. Re-roofing can be a more cost-effective option, as it saves time and labor by not having to remove the old roof.

Here are some circumstances when re-roofing might be necessary:

  • Age of the Roof. The age of your roof is a key factor. If your roof is between 12 and 20 years old and most of it is in good overall condition, a re-roof might be an option.
  • Minor Damages. If your roof has minor issues, such as a few missing or damaged shingles but is otherwise structurally sound, re-roofing can be a feasible choice.
  • Budget Constraints. Re-roofing is generally less expensive than a complete roof replacement because it involves less labor. If you’re on a tight budget, this might be a good option.
  • Time Constraints. If you need a quick solution due to an impending sale of the house or approaching harsh weather, re-roofing can be faster than a full roof replacement.

Benefits of Re-Roofing

  • Cost Savings. Re-roofing can be less expensive than a complete roof replacement as it requires fewer materials and less labor.
  • Time Efficiency. Since the existing roof does not need to be removed, re-roofing can be completed more quickly than a full roof replacement.
  • Prevents Leaks. By adding an additional layer of protection, re-roofing can help prevent water leaks and keep small problems from developing into larger ones.
  • Improved Insulation. A new layer of shingles can enhance the insulative qualities of your property, potentially leading to lower energy costs.
  • Visual Appeal. Re-roofing can give your home a fresh, updated look without the expense and time commitment of a full roof replacement.

How Does Our Re-Roofing Work?

At Rainy City Roofing, here’s what our reroofing Portland contractors usually follow:


Our first step is to inspect the current condition of your roof. This will help determine if re-roofing is a viable option or if a full roof replacement is necessary. We will provide an estimate of the cost and timeline for the project. if you agree, we will move on to the next step.


Before we start re-roofing, we make sure the area is properly prepared. This includes protecting your property and surrounding areas from any damage that may occur during the process. We also remove any loose or damaged shingles and clean the roof surface.


Once the existing roof is prepared, we will install a new layer of shingles on top. It’s important to note that re-roofing can typically only be done once. If your roof already has two layers of shingles, it may not be able to support a third.


After the new shingles are installed, any additional components such as flashing or vents are added to complete the job.

Final Inspection

Once the re-roofing is complete, we will perform a final inspection to ensure everything meets our high standards. We want to make sure your roof is in top condition and provides long-lasting protection for your property.

Re-Roofing Vs. Roof Replacement

Re-roofing is not always the best option for every roof. In some cases, a full roof replacement may be necessary to ensure the structural integrity of your property.

Here are some key differences between re-roofing and replacement:

  • Number of Layers. Re-roofing can only be done once, meaning you can only have two layers of shingles on your roof. A full replacement can be done with any number of layers.
  • Cost. Re-roofing is generally less expensive than a full replacement, but this may vary depending on the size and condition of your roof.
  • Durability. While re-roofing can provide additional protection and prolong the lifespan of your roof, a complete replacement will offer the longest-lasting solution.

Does My Insurance Cover Re-Roofing Services?

Whether re-roofing is covered by insurance largely depends on the policy and the reason for the re-roofing. In general, home insurance policies provide coverage for damages that are sudden and unexpected. This means if your roof was damaged due to a peril such as fire, wind, hail, or other weather-related events, you may be covered for repairs or replacement.

However, if your roof needs to be re-roofed due to wear and tear or old age, it’s unlikely that your insurance will cover the costs. Most insurance companies consider roof maintenance as the homeowner’s responsibility. Therefore, damage that results from neglect or failure to maintain the roof might not be covered.

In some cases, insurance companies may only cover the depreciated value of the roof if it’s older, typically over 20 years. It’s important to review your specific policy or speak with your insurance agent to understand what is and isn’t covered.

How Long Does a Re-Roofed Roof Last?

The lifespan of a re-roofed roof can vary depending on factors such as the quality of materials used, installation method, and weather conditions. Typically, a new asphalt shingle roof can last between 15 to 30 years. In Portland where we experience harsh weather conditions, it’s important to invest in high-quality materials and proper installation to ensure the longevity of your roof.

Ultimately, no matter the quality of the materials without proper care and quality craftsmanship, the roof won’t last as long as it could.

Tips on How to Maintain a Re-Roofed Roof

To maintain your re-roofed roof, consider the following tips:

  • Regular Cleaning. Keeping your roof clean can help prolong its life. This involves removing debris such as leaves, branches, and dirt that can accumulate over time.
  • Trimming Trees. Overhanging tree limbs can scratch and damage your roof. Make sure to trim any branches that come too close to your roof.
  • Professional Roof Inspection. Regular inspections by a professional roofer can help identify potential issues early before they become major problems.
  • Check for Damage. Look for signs of damage like punctures, cracks, missing shingles, and other issues. Early detection and repair can prevent further damage.
  • Proper Ventilation. Ensuring proper ventilation can help reduce heat buildup, which can prolong the life of your overlay roof.
  • Quality Materials. The lifespan of an overlay roof also depends on the quality of materials used. Higher-quality materials tend to last longer.



A new roof does wonders for your property! Not only does it increase the curb appeal and look of your home, but it can also increase the value of your home substantially. We love working with local homeowners to provide a wide variety exceptional roof installation services for repairs, complete remodels, and more.


In addition to roofing and re-roofing services for Portland homeowners, we also work with local businesses. We know how important a well-built roof is for any building, but this is especially true for PNW businesses. With unpredictable weather and lots of rain every year, we give Portland businesses the peace of mind they need to know their businesses will stay nice and dry in any season.

Increased Value

A brand new tear-off roof is a major selling point for a house. It adds resale value to your home. If you know you’re going to sell your home at some point down the road, a tear-off is probably the best for you.

A Full Replacement

Everything is brand new when you invest in a tear-off roof job. This means that you will no longer have any rots, leaks, or other damage that may have occurred because of the condition of your old roofing materials. Our experienced roofing contractors take everything off your roof, so we get a clear look at what’s going on under your shingles.

Higher Quality

Since you will be getting a brand new roof, we will be able to assess all the high-risk areas of the structure to give you the best quality product possible. This means we can install new flashings and ensure that your roof is completely watertight for years to come.


When we replace your entire roof, it will last much longer than an overlay job. This is because you will have brand new materials that are less susceptible to wear and tear brought on by heat-trapping, which is very common when you have extra layers on your roof.
