If you're wondering why roofing quotes can be so far apart, you're not alone. So, let's clear up the confusion behind those different roofing quotes. This way, you can feel good about picking the right company for your home (and your wallet!).

What Changes Your Roofing Quote?

There are a few key reasons why prices range amongst roofing estimates, and not all of them are obvious at first look. In this blog, we will discuss aspects that can influence roofing quotes, such as:

The Job Itself

Not all quotes are for the exact same work. Some roofers might include tearing off and hauling away your old roof stuff. Others might just plan to put new shingles over your old ones (called a "roof-over"). That's cheaper, but it can cause big problems later.

Always read the small print or ask what exactly they're quoting. Are they replacing the stuff under the shingles? The metal flashing? Adding vents? These small things really matter.

Replacing Wood

When your old roof comes off, sometimes what's underneath isn't in great shape. We're talking about the wood that makes up your roof's "decking" or "sheathing." If it's old, wet, or has signs of rot, it has to be replaced. This is super important because this wood is what your new roof will be fastened to, and if it's weak, your new roof won't last.

Here's the tricky part: Some roofing quotes include an estimate for this work, assuming a certain amount of wood might need replacing. Other quotes might not include it, and instead charge you extra after they tear off the old roof and see the damage. This can be a big surprise bill!

Worker Costs

A big part of any roofing job is the cost of the workers. Some companies hire outside workers or day laborers to save money. Others use their own trained teams who know how to install specific brands and materials.

While a lower worker cost might seem good for your wallet, it can hurt your roof's life in the long run. Bad installation is one of the main reasons roofs break down too soon.

Guarantees and Warranties

That $5,000 quote might not come with any guarantee, or maybe just a one-year promise on the work. Meanwhile, the $12,000 quote might include a 10-year guarantee on the work and a 25-year product guarantee from the maker. Make sure you know what kind of peace of mind you're getting (or not getting) with each quote.

Insurance and Licenses

Good roofers carry general insurance and workers' compensation. Great roofers are GAF President's Club winners, like Blue Sky Roofing! If a roofer is cutting corners on their business costs, they might offer a lower price. But that could leave you on the hook if something goes wrong. Roofers without insurance or licenses might save you a buck now, but cost you thousands later.

How to Make a Smart Roofing Choice

Okay, so you've got three roofing quotes, and now you get why they're different. But how do you pick the right one? Here's your simple plan:

  • Compare Line by Line: Ask each roofer for a detailed quote. You want to know exactly what's included (materials, labor, tearing off the old roof, cleanup, guarantees, and any possible extra costs). If a roofer gives you just one total number with no breakdown, that's a warning sign.
  • Ask Questions: If something doesn't make sense, ask! A good roofer will be happy to explain their quote. Ask about materials, guarantees, timelines, how much experience their crew has, and what happens if they find unexpected damage once the old roof is off.
  • Think About the Whole Value, Not Just Price: Think about what you're getting, not just what you're spending. A slightly higher quote from a well-reviewed, insured, and certified roofer is almost always a better deal than a super-low price from someone with a pickup truck and a ladder.This is your roof. It protects everything and everyone under it. Picking the cheapest bid without thinking about the big picture is like buying cheap parachutes: sure, they're cheaper... but you might not want to try them out.
  • Check Reviews and References: Always verify the roofing contractor. Look up Google reviews online, check with groups like the Better Business Bureau, and ask the roofer if they can give you references or show you examples of recent jobs. A trustworthy roofer will be proud to share their past work.
  • Trust Your Gut: Sometimes your feelings tell you what numbers and papers can't. If someone seems shady, pushy, or too good to be true, they probably are. Go with a roofer who talks clearly, answers your questions honestly, and treats you with respect from the start.

Roofing Quotes Shouldn't Be a Gamble

Getting a few quotes is smart, but don't just pick the cheapest one without doing your homework. Your roof is one of the most important parts of your home, and cutting corners on quality or expertise now can lead to leaks, damage, or needing a new roof too soon.
