Greg Giving His Formal Stamp Of Approval Main

SmartSeries Case Study: The Renton Man Who Reroofed His Home 3 Times In 20 Years

The Third Time Was Finally The Charm… 

Because He Called RoofSmart.

Our SmartSeries showcases how we take a more intelligent approach to roof replacement than your average roofing company in Greater Seattle. We don’t just address the symptoms—we fix all underlying problems to maximize your roof’s lifespan and performance.

Most people reroof their homes once in their lives—MAYBE twice. But Renton homeowner Greg? He was going on his third roof replacement… in the last 20 years.


Because the two previous roofers put the wrong TYPE of roof on his home. As a result, Greg’s home had experienced several big problems. 

Here’s what happened—and how we solved Greg’s roofing woes for good.

Square Pegs; Round Holes

When we arrived at Greg’s home for his free inspection, we didn’t even need to get out of the truck to determine his problem. We saw it as soon as we pulled into the driveway.

Take a look at this photo of Greg’s home and old roof…

Greg’s Home and Old Roof

Can you guess Greg’s issue based on this picture?

Take a good look at it. What is it about his roof that’s different from most residential roofs?

Answer in three…



What makes Greg’s roof uncommon is that it’s low-sloped. Greg was having such massive problems because roofers kept installing asphalt architectural shingles on his home.

That’s a problem. Architectural shingles and flat/low-sloped roofing go together about as well as peanut butter and garlic. 

In other words: They don’t.

The “Faults” Caused By Asphalt 

Greg’s main problem was water damage. When you put asphalt shingles on a flat or low-sloped roof, water will eventually get under those shingles. After all, it’s just sitting there with nowhere else to go.

You can tell when water is trapped when the shingles have a “scooped” look. Here is a photo of Greg’s old roof so you can see this effect…

Scooped Asphalt Shingles
Water caused the shingles to curl and “scoop.”

Greg’s moisture issue ran DEEP and caused several problems:

  • The roof deck was sagging two inches from end to end.
  • The trusses were broken.
  • Mildew was growing on the shingles.
  • The ceiling was drooping.

As you can see, we had our work cut out for us. 

But we’re RoofSmart. Handling the “tough stuff” is our specialty.

Starting Fresh

First thing was first—all the “under the shingles” stuff had to go. We tore out the rotted wood, removed the roof deck, replaced the trusses, and reframed the ENTIRE roof.

Here are a few photos of the process…

Once we had all the underlying issues taken care of, we had one mission left: Make certain this is the LAST time Greg needed to replace his roof.

“Heavy Metal”

To ensure Greg never had moisture issues with his roof again, we installed the roof material his home actually required—metal.

Because it has no seams or gaps, water can’t penetrate standing seam metal roofing. And since it has a smooth finish, it easily sheds snow and rain. This makes metal the appropriate material for low-sloped roofs like Greg’s.

Here are some photos of Greg’s brand-new, lifetime-lasting metal roof…

Roofers Who Care

Crew Chief Alejandro gets a special shoutout on this project. He was the one who A) discovered all the underlying problems and B) made the decision to completely gut the old roof and start over.

We COULD have taken the easy route like the last two roofers Greg hired. We COULD have just replaced his shingles and called it a day. But that’s not the kind of roofing company we are because that’s not the kind of PEOPLE we are.

Everyone at RoofSmart genuinely cares about doing things the right way… even if it’s harder and takes longer.

Issaquah Roof Water Damage

Solving This Issaquah Home’s “Mysterious” Water Damage Issues

You Can’t Judge A Book By Its Cover. And You Can’t Judge The

Condition Of Your Roof By Its Shingles.

Our SmartSeries showcases how we take a more intelligent approach to roof replacement than your average roofing company in Greater Seattle. We don’t just address the symptoms—we fix all underlying problems to maximize your roof’s lifespan and performance.

This is a case of beauty being only skin deep… and a prime example of how pretty roofing shingles can cover up MASSIVE underlying problems.

A family in Issaquah called us after their elderly father passed away. They wanted to sell his home, but the ceiling was leaking in multiple areas. 

But here’s the thing: The shingles themselves were totally fine—they were in near-perfect condition. As they should be, since the previous roofer put them on only 12 years prior.

So, why was the ceiling leaking? That’s what this family called us to find out. 

Here are some images of the different leaks and water damage the home was experiencing…

What, exactly, was the root cause of the problem? It wasn’t just one thing. So let’s start with the most egregious issue: the attic.


The Attic Of Your Nightmares

We’ve been around the block a time or ten. We know what the average Seattle Metro area roofer looks for… and what they don’t. And something they virtually NEVER address is attic ventilation.

This time was no different. When the previous roofer came 12 years ago, they installed pretty new architectural shingles… but that’s it. They DIDN’T inspect the attic’s ventilation situation. And that ended up being a big reason for all the roofing trouble.

Proper attic ventilation is something we preach constantly. So the first thing we did was—you guessed it—inspect the attic. 

As soon as we poked our head in, we just about choked. The attic was stiflingly humid. And there was mold, mold, and more mold.

Here are a few photos of the nightmare mold situation in the attic…

There were two reasons for mold in the attic:

  1. The insulation was blocking the ventilation.
  2. There wasn’t enough intake ventilation.

Here are a few examples of the insulation blocking air from escaping the attic…

Like we always do, we took a bunch of pictures and showed them to the family. They were both disgusted and blown away. 

They’d called several other contractors to do some work on the house. They said none of those contractors brought up the mold situation. Fortunately, they eventually called us.


How We Fixed The Attic Ventilation Issue

The attic wasn’t just moldy—it was the source of many of the ceiling leaks. Fixing the attic was essentially a three-step process: 

  • We threw away all the mold wood and replaced it.
  • We moved the insulation and added baffling so air could actually escape the attic.
  • We added more intake ventilation to balance the airflow in the attic.

Here are a couple photos of the intake ventilation we installed…

Finally, the attic could breathe. That was one problem down. But we also had to address the improperly installed skylights—the other big reason for all the water damage.


The Skylights Were Like Bathtubs

The skylights a previous contractor installed were rated for a 3/12 slope. Basically, that means they needed to be installed on a slant.

The contractor, however, installed them flat. Here are a few photos…

Installing the skylights flat essentially turned them into bathtubs with stagnant water. Rainwater ponded on top, so the water eventually leaked through the skylights and inside the home.

Fixing this issue required two main steps:

  • Reframing the skylight curbs
  • Install custom flashing on the skylights

Here are some pictures of that process…

This process ensured water would no longer pool on and around the skylights. Leak problem solved!


Last But Not Least: Installing Beautiful New Shingles

The old roofing shingles were in good condition. But once you tear off roof shingles, you can’t reuse them. So we performed our SmartMatch™ Needs Analysis to determine the right new shingles for the customer. 

Based on the customer’s needs and budget, we pinpointed the Owens Corning Duration® Series Shingle as the best choice. It has a 30-year warranty, triple-fiberglass reinforcement, water-shedding technology, and 130mph wind resistance. Plus, its “No Guess” nailing zone ensures the most consistent and high-quality installation.

Here is the end result…

Finally, this home had a new roof that not only looked beautiful but also functioned flawlessly.

5 layers of roofing shingles

SmartSeries Case Study: Bellevue Farmhouse With A 5-Layer “Roof Sandwich”

The Ultimate Example Of Roofers Kicking The Can Down The Road.

Our SmartSeries showcases how we take a more intelligent approach to roof replacement than your average roofing company in Greater Seattle. We don’t just address the symptoms—we fix all underlying problems to maximize your roof’s lifespan and performance.

If you want picture proof of how lazy roofing companies can be, this is the case study for you.

Sam owned a historical farm in Bellevue. He’d recently built a new house on the land, but he left the old house up.

Sam called us for two reasons. First, he wanted a new metal roof installed on his pole barn. Second, the old farmhouse’s roof was leaking, so he needed to replace it.

Replacing the pole barn’s roof was relatively straightforward. Replacing the farmhouse’s roof? Let’s just say that project had “layers.”

The Roof Sandwich

We first started the re-roofing job on Sam’s old farmhouse. While we were removing the old shingles, we were blown away by what we found: Not one… not two… not three… not four… but FIVE LAYERS of old shingles.

During the initial inspection, we believed there were two layers of shingles. How did we not see the other three? Because the prior roofer cut the layers back at the edges to hide them. Sneaky!

Here are a few photos of the removal process:

Why, exactly, were there so many layers? Because all the previous roofers just kept installing new shingles over the existing ones. None of the roofers bothered to tear off the old shingles.

In other words, roofers kept kicking the can down the road.


Elbow Grease… Lots And Lots Of Elbow Grease

Removing all of these shingles was tough. The “sandwich” was so thick that the previous roofer used framing nails instead of roofing nails for the top layer of shingles. To put that in perspective, framing nails are about three times longer than roofing nails.

In the process of removing the shingles, we broke two shovels!

Here are a few more pictures of the removal process:

What we found underneath didn’t surprise us. There was a ton of rot and water damage. This, plus the sheer weight of all the shingles, actually caused Sam’s ceiling to sag. 

This was a BIG problem, and it left Sam with two options: reframe the roof or completely tear out the ceiling. Since tearing out the ceiling would be a very costly and messy process, Sam chose to reframe the roof.

So we got to work…

After fixing all the “under the hood” problems, we were finally able to start installing the new shingles. For this project, we used Owens Corning Duration shingles because of the good balance between durability and cost.

Here are a few photos:

The roof sandwich made things take a little longer than expected, but we finally finished Sam’s new farmhouse roof.

But our work wasn’t done.


One Roof Down… One To Go

Remember, we were also re-roofing Sam’s pole barn. Thankfully, that was much more straightforward. No roof sandwiches. No saggy ceilings.

We initially planned to complete Sam’s project in two days. That was before we found the roof sandwich. When all was said and done, we worked on Sam’s job for an entire week.

But let’s face it—sometimes it takes a little longer to make sure things are 100% RIGHT. There was NO WAY we were going to continue kicking the can down the road like the previous roofers. That nonsense ended with us.

If that sounds like the kind of roofer you’re looking for in the Greater Seattle area, get in touch. We would be honored to provide you with a free roof inspection. No games or pressure—we provide you with the information you need to make the best decision for your home.
