Centennial Roofing, From Southglenn to Smoky Hill

If your Centennial roof leaks, it’s probably not the shingles. On the steep, cut-up rooflines common here, water gets in at the valleys, the step flashing and the chimney. And once repairs pass a quarter of the roof, the city requires a full tear-off. Here’s what that means for your house, west side to east.

What Centennial Roofs Are Actually Like

Around Southglenn and Willow Creek, homes are mostly 1970s and 1980s, many on a second or third roof. Piney Creek and Foxridge run a little newer. A lot of Centennial houses have moderate to steep pitches with rooflines that intersect, and that’s where cheap workmanship shows first: your valleys, step flashing and chimney, not the open shingles.

So those details are what we look at hardest on your roof. Most leaks we get called to in Centennial were never a shingle problem.

Centennial, West to East

Centennial is a young city, incorporated in 2001, but plenty of its neighborhoods aren’t young at all. What your roof needs changes as you move east.

  • Southglenn and the west side. Some of the oldest housing in the city, much of it on a second or third roof. This is where we most often find tired decking and old roof vents that were never updated.
  • Willow Creek. Established streets with mature trees over many of the roofs. Trees are lovely and hard on your roof: shade, leaves in the valleys and branches rubbing the shingles all shorten its life.
  • Foxridge. Steeper pitches and more intersecting rooflines than the older streets to the west, so there are more joints to keep watertight.
  • Piney Creek. Bigger two-story homes. Big roofs with lots of valleys, dormers and roof-to-wall joints, which is exactly where workmanship shows first.
  • Smoky Hill and the east side. Newer homes on more open ground. These roofs are rarely worn out; when they fail, it’s usually hail or wind.

Where Your Centennial Roof Will Leak

When we trace a leak on a Centennial home, it’s almost never the open stretch of shingles. It’s one of a short list of details, and these are what we check on every inspection:

  • Valleys, where two slopes meet and all their water runs down one line.
  • Step flashing along a wall, which often gets reused from the old roof when it should have been replaced.
  • Kick-out flashing at the bottom of a roof-to-wall joint. When it’s missing, water runs behind your siding instead of into the gutter.
  • Chimney flashing and chase covers. A rusted cover on top of a framed chimney can leak into the house and look exactly like a roof leak.
  • Pipe boots, whose rubber collars crack in Colorado sun long before the shingles around them wear out.

Split-Levels and Low-Slope Sections

Plenty of Centennial homes are split-levels, and those often have a shallow section of roof over a porch, an addition or the lower level. Shingles are made to shed water on a proper slope. On a roof that’s too flat, they hold water and leak early.

If part of your roof is too shallow for shingles, we’ll tell you, and price the right material for that section instead of running the same shingle across the whole house because it’s quicker.

What Centennial Requires, and What It Means for You

Centennial's Building Division publishes its residential reroof rules. They’re worth knowing before you hire anyone:

  • A permit for anything over 100 square feet, posted at the house until the final inspection. A smaller repair doesn’t need one.
  • Repairs covering more than a quarter of the roof require a complete tear-off and reroof. So a big "repair" quote may really be a replacement.
  • A replacement removes every layer down to the deck, and used or salvaged materials aren’t allowed.
  • Ice barrier underlayment on all roofs, and drip edge on every edge.
  • A mid-roof inspection on every reroof permit, as well as the final. Centennial accepts photo inspections for both.

Centennial Roofing Questions

My Centennial roof only leaks in heavy rain. Is it the shingles?

Rarely. A leak that only shows up in a downpour is usually a flashing, valley or pipe boot problem, where the volume of water overwhelms one weak spot. That’s typically a repair, not a new roof, and we’ll quote it that way.

Do mature trees shorten my roof’s life?

They can. Shade keeps the roof damp longer, debris clogs the valleys and gutters, and branches that touch the roof grind the granules off the shingles. Keep branches trimmed well back and the valleys clear, and your roof will last noticeably longer.

Is a split-level harder to re-roof?

Not harder, but more detailed. There are more places where the roof meets a wall, and often a low-slope section that needs a different material. Those details are where the time goes, and they’re the parts worth paying for.

Should I repair or replace an older roof in Southglenn?

It depends on what’s left of it. If the shingles still bend without cracking and the problem is one spot, repair it. If they’re brittle, bare of granules and failing in several places, a repair only buys you a season. We’ll show you the photos and let you decide.
