Howard County Roof Replacement: An Unflashed Chimney and a Roof That Had Run Its Course

This Howard County roof replacement started with a handful of missing shingles and ended with a discovery that explained a lot, like a chimney that had never been properly flashed. Combined with a roof that had already been repaired multiple times and was nearing the end of its serviceable life, the case for a full replacement was clear. The crew re-decked the entire roof with half-inch CDX plywood, ran the full waterproofing system, flashed the chimney correctly for the first time, and finished with CertainTeed Landmark Pro in Max Def Driftwood.

For a Howard County rancher with a straightforward roof geometry, this was a project where doing the job right from the deck up made far more sense than continuing the cycle of repairs that had defined this roof for years.

Project Overview

The homeowner contacted Roof Right after noticing missing shingles. Missing shingles on their own do not always mean a full replacement is necessary, but they are a reason to take a closer look at everything else. On this Howard County roof, that closer look told the full story.

The roof had already been repaired multiple times. Repeated repairs on an aging roof are a signal worth paying attention to. Each patch addresses a symptom without resetting the underlying issue, and over time the repaired areas create an inconsistent surface that is harder to maintain and easier for water to find its way through. When a roof has been patched in multiple locations and is still losing shingles, the repairs have run their course.

The chimney finding was significant on its own. A chimney without proper flashing is an open invitation for water to travel directly into the wall assembly and attic at one of the most vulnerable transition points on the entire roof. The fact that it had gone unaddressed through however many repair visits the roof had seen made the case for a full Howard County roof replacement and a proper installation even stronger. Everything needed to be reset, not patched again.

The Howard County Roof Replacement Process

With a full replacement confirmed, the crew stripped the old shingles and evaluated the deck below. The entire roof had to be re-decked with new half-inch CDX plywood before any new roofing materials went down. CDX is a construction-grade plywood that provides a consistent, solid nailing surface and handles moisture exposure during installation. Re-decking the full surface rather than replacing individual sheets ensures the new system has a uniform foundation from edge to edge.

Ice and water shield was installed first along the eaves and around all penetrations. On a roof with this history, proper coverage at the eaves and around the chimney was especially important. The self-adhering membrane provides a watertight secondary barrier at the areas most likely to see moisture infiltration under real-world conditions.

Synthetic underlayment was then run across the full deck, providing a durable secondary moisture barrier beneath the shingles. Unlike traditional felt, synthetic underlayment resists tearing during installation and holds up better under foot traffic and weather exposure during the installation process.

The chimney was fully flashed as part of this Howard County roof replacement, properly this time, with metal integrated into the roofing system rather than left exposed or absent. All vent pipe penetrations were flashed and integrated into the shingle courses above them before the installation was complete.

Product Spotlight: CertainTeed Landmark Pro in Max Def Driftwood

For this Howard County roof replacement, the homeowner chose CertainTeed Landmark Pro in Max Def Driftwood, a strong product choice that suits a Maryland rancher well.

Landmark Pro is a step above CertainTeed’s standard Landmark line. The shingles are heavier, carry stronger wind resistance ratings, and have a thicker profile that gives the finished roof a more dimensional appearance from the street. For a homeowner who just invested in a full re-deck and new installation, moving up to Landmark Pro is a decision that pays off over the life of the roof.

Max Def Driftwood is worth understanding separately from standard Driftwood. The Max Def color process uses a wider spectrum of granule color variation to produce more natural depth and contrast across the roof surface. Standard Driftwood is a reliable, popular color: a warm blend of gray, brown, and tan tones. Max Def Driftwood takes those same tones and adds more dimension, more movement, and a finished appearance that reads as genuinely textured rather than flat. On a rancher where the roof is one of the most visible elements of the exterior, that distinction is visible from the curb.

CertainTeed backs Landmark Pro with a lifetime limited warranty and SureStart protection, which provides full replacement coverage during the early years of the roof’s life.

Signs You May Need a Howard County Roof Replacement

A roof that has been repaired more than once deserves a professional assessment. Here are the warning signs that a Howard County roof replacement may be the right call:

• Missing shingles in multiple locations — isolated loss can be repaired, but recurring loss across the roof signals a system that is failing broadly
• A history of repairs on the same roof — multiple patches over time indicate the roof is being managed rather than maintained, and the underlying system is declining
• A chimney with no flashing or deteriorated flashing — an unflashed chimney allows water direct access to the roof assembly at one of its most vulnerable points
• A roof deck that is soft, uneven, or showing signs of moisture damage — compromised plywood cannot support a new roofing system effectively
• Granule loss accumulating in gutters or downspouts — heavy granule loss means the shingles are breaking down and no longer protecting the deck below
• Shingles that are curling, cupping, or cracking — physical deterioration that repairs cannot reverse
• A roof that is 20 or more years old with an unknown repair history — age combined with uncertainty is reason enough for a professional inspection

If your roof has been patched more than once and is still showing problems, the patches are not the answer anymore.

Roof Right: Howard County Roof Replacement Done the Right Way

The story of this Howard County roof replacement is straightforward: a homeowner who came in with a small concern and got an honest assessment of what the roof actually needed. Missing shingles were the presenting issue. A worn-out deck, a history of repairs, and an unflashed chimney were the real problems underneath.

Addressing all of it properly with a full re-deck, correct flashing at every penetration, a complete waterproofing system, and CertainTeed Landmark Pro shingles backed by a lifetime warranty means this roof is not going to need another round of patches. It is built to last.
