How Much Does It Cost to Reroof Your Home?


Before introducing ONDUVILLA to the North American market, we commissioned a third-party study of homeowners and roofing contractors.  This was to get a better sense of demand for an entirely new category of roofing.  But first, we needed a sense of the future demand for reroofing, which ONDUVILLA is an especially attractive option. The answer might surprise you. Nearly two-thirds (64%) of homeowners plan to reroof their home in the next five years.

If that stat includes your home or your customers’ homes, the next discussion is cost, which can greatly vary depending on roof size and roof type, but ultimately it’s the roofing material being used.  Fortunately you’re not completely in the dark about estimating a cost. offers a detailed cost guide so you can get a sense of what to budget.

The following is a guide to the three main factors in reroofing costs:

  • House size: It goes without saying – the bigger the house, the bigger the roof. Any roofing contractor will need to see your house in person to give you an accurate cost, but you can help narrow the field by asking for a ballpark estimate based on your roof’s square footage. If you aren’t sure, here’s a handy how-to guide for measuring your roof size.
  • Height and pitch: These two factors directly impact how long it’ll take a roofing contractor to complete the job, and in turn, how expensive it’ll be.
  • Material: There’s a range of roofing options available to homeowners, and what you choose will significantly affect your overall cost. This is why so many homes use asphalt shingles – they’re the cheapest option in town, and until ONDUVILLA, the only option in that price range.


If you’re looking for some kind of range, also collected roof installation costs and has broken out the cost trends. The graphic above shows the national average, but on the site there is a tool that provides a cost analysis for your zip code.

Remember, the costs quotes on the site include tear-off costs for the old roof. ONDUVILLA can be installed directly over one course of Asphalt shingles, saving that cost and space in the landfill.

Reroofing 101: What You Should Know Before You Reroof


The typical roof lasts about 20 years, and if you’ve bought an older house or if you’ve lived in your house for a long period of time, it might be time for you to consider a replacement roof. Think you might be due for a reroof?

Here’s how to determine if you need a new roof:

  • Start by assessing the condition of your roof from the outside. Look for missing shingles, weathered or thinning shingles and the curling and buckling of shingles.
  • With asphalt tile roofs, the presence of shingle granules in the gutter is also a sign that your roof is ready to be replaced.
  • Keep an eye out for sagging, which could indicate a leak in your roof, and could be a sign of significant structural issues.
  • After inspecting the outside of your home, be sure to inspect your attic and crawl space for signs of water damage. Additionally, take note if any light is shining through.
  • You can expect the reroofing process to take 1-2 days for uncomplicated small to moderate sized homes, and up to a week or more for extremely large homes with complicated rooflines.

Once you’ve decided that you’re ready for a new roof

Three final reroofing factors to take into consideration:

  • Temperature: Ideal temperatures for a reroof are between 50 and 75 degrees Fahrenheit. Cold temperatures do not allow for a great seal when using asphalt shingles. Hot temperatures can be dangerous for workers who may be prone to heat exhaustion.
  • Risk of precipitation: Rain can be problematic for a reroof that involves tearing off your existing shingles. Precipitation also causes slippery conditions – whether it’s ice, snow or rain – making your roof unsafe for installers. Ideally you’ll want to plan your reroof install during a period of dry weather.
  • A better looking roof: There are many new roofing alternatives that can improve the appearance and property value of your home.  These include architectural shingles and new roofing materials that allow you to upgrade to the look of shake, slate or tile at an affordable cost.

Hopefully this helps in determining if your roof needs replacement. Keep in mind, mid-late spring and early fall are generally recognized by roofing professionals as the best time of year to replace your roof. But because of this, homeowners also should be aware that these are the busiest times of year for roofing contractors, so be sure to meet with your contractor sooner rather than later.

Tips on Hiring the Best Roofing Contractor


A new roof isn’t cheap. In fact, you can check out our recent post on how to estimate the cost of a new roof to get a better idea. A significant chunk of the cost isn’t just the roofing material, but also the skill and time of your roofing contractor to install it. And, just as you want a roofing material that’s durable and will last several decades at the least, you also need to select a reputable roofing contractor to ensure your roof is installed correctly. This will help prevent more headaches down the road.

The National Roofing Contractor Association (NRCA) agrees, and has even developed a website for homeowners appropriately titled, which among its many features, preaches the importance of knowing how to vet your roofing contractor.

We recommend you take some time reviewing the site whenever it comes time to replace your roof. However, we do want to mention a couple of the more important items that can’t be stated enough when determining who’s going to be in charge of one of your home’s most critical elements.

  • Ask for a copy of their liability insurance: Installing a roof is serious business, and there’s good reason why it should only be done by professionals. It’s dangerous work, and for more legal reasons than we can think of without asking counsel, you need to make sure whoever gets on your roof is properly insured.
  • Get a written proposal detailing cost and what needs to be done: This is a form of insurance in and of itself. This lets you know exactly what needs to be done, and has an agreed-upon price that ensures you and your roofing contractor are on the same page when it comes time to settle up.
  • Check out the company’s Better Business Bureau rating: While sites like Yelp are becoming increasingly common to share reviews, the BBB is still one of the most reliable places to determine a business’s reputation. A couple minutes on the site could steer you clear of a contractor with a regrettable track record.
  • Don’t choose solely on price: Too-good-to-be-true prices should be met with some amount of skepticism. It’s always recommended to get at least three estimates, but if one is noticeably cheaper than the others, there might be a reason for it. If you do decide to go with the one with the lowest cost, you might want to ask for references to make sure you shouldn’t expect low-balled quality as well.

Remember, a roof is one of the most important aspects of your home – both structurally and aesthetically. Take the time to vet your roofing contractor so you can have peace of mind that the roof over your head isn’t going anywhere any time soon.

How to inspect your roof

House Search


Inspecting your roof should be an integral part of your maintenance routine as a homeowner. At the very least, you should inspect your roof once a year.  Some experts even recommend keeping records of your roof’s condition bi-annually during both the spring and fall. If the area that you live in experiences severe or extreme weather conditions, you may want to inspect your roof more frequently.

Catching problems early can mean the difference between an easy fix and an expensive large scale project. Not properly maintaining your roof may also lead to problems with your homeowner’s insurance policy.

If you have shingles, start by taking a close look at their condition. Ask yourself the following questions:

  • Do I see any loose shingles?
  • Are there granules in my gutters?
  • Do any of the shingles have cracks, or do they appear to be buckling or curling?
  • Is my roof missing any shingles?

If you have an alternative type of roofing:

  • Metal roofs: Look for signs of rust, corrosion, and pitting
  • Wooden shingles/shake: Inspect for dry rot and warping
  • Slate and clay tiles: Look for missing, chipped and/or broken pieces

Next inspect for structural damage. Roof sagging could be a sign of a major roof problem as a result of water damage, poor ventilation, faulty roof materials or too much weight from rain, ice or snow. Also look for loose, damaged or missing flashing, which can lead to water damage.

After you’ve completed a thorough inspection from the outside, it’s also important to examine the inside of your home for signs of a deteriorating roof. In your attic, start by checking your insulation for moisture, this could be a sign of a roof leak. Another red flag when inspecting your roof from the interior of your home is light streaming through. Even small holes in your roof can cause serious damage.

During your inspection, if you find multiple issues with your roof, it may be time to call an experienced contractor for a professional’s opinion.

The Trend Away from Bland Exterior Design Should Extend to the Roof


Builder magazine recently published a great “Special Report” article titled “Banishing Bland: Trends in Residential Exterior Design.”

The second paragraph struck me the most:

“Nationwide, builders and architects are seeing a renewed emphasis from their customers on exterior styling, and that is playing out in mixing materials and textures, adding more and larger windows, or windows in various configurations, and using architectural elements to add oomph to what otherwise [would] be a bland box.”

The report, like the paragraph, focuses on everything below the eaves. What about the roof?  There is a huge market for homeowners who would consider a choice of materials, especially when their budget precludes tile, slate or other high-end roofs. How do I know that? Well we commissioned 3rd-party research a few years ago and they asked homeowners and contractors some pointed questions about this very subject.

The research found a “latent desire for new roofing options,” largely driven by near domination of asphalt shingles in the roofing market when higher-end materials are not within the budget. Consider that of the 500 homeowners our research surveyed, 89% said they had asphalt shingle roofs (3-tab + architectural) and of the 200 contractors surveyed, 80% of the roofs they installed in the prior year (2010) was asphalt shingles.*

Is this just because demand is that high for shingles? No of course not! The homeowners and contractors need options.

The research indicates that homeowners and contractors would consider an option to asphalt shingles if they were provided choices that they could afford and trust.

*These stats are all steep-slope roofs.
