Exploring the Impact of Roof Components on Efficient Roof Replacement

Observe your rooftop. Does it present a flawless, squared-off appearance? Alternatively, does it exhibit the elegance of a gently sloping hip roof, devoid of any chimneys, dormers, vents, or turrets? If the latter describes your situation, you’re in luck – your forthcoming roof replacement is poised to be a straightforward endeavor.
Yet, more often than not, your roof boasts various architectural elements. Perhaps a chimney, windows, or even a cricket – all of which we’ll delve into later – grace its surface. These distinct shapes and features introduce an element of complexity to the roofing process.

Navigating the Intricacies of Roof Shapes and Appendages

Certain roof configurations pose greater challenges when it comes to replacement. Any departure from a level deck engenders ridges, valleys, or seams, demanding meticulous handling to prevent water infiltration.
Tailored cutting of the base mat becomes necessary, accompanied by the use of specialized flashing. Employing innovative methods, shingles might need to be arranged to achieve an aesthetically pleasing outcome.
Remember, your roof necessitates proper ventilation. Roof airflow constitutes an additional factor. The same architectural elements that enhance visual appeal or fulfill specific functions might inadvertently impede ventilation.
Undoubtedly, subpar roof ventilation accelerates the deterioration of your shingles.
Herein, we shall explore various approaches your roofing professional can adopt to address the distinct waterproofing and ventilation requisites of your roof.

Custom Solutions for Your Exceptional Roof and its Replacement

  • Chimneys and Exhaust Vents:
  • Challenge: Prone to leaks
  • Solutions: Cricket, flashing, sealant, underlayment
Numerous residences possess at least one chimney – even sans a discernible fireplace! During a roof replacement, chimneys warrant special attention.
Does your chimney intrude upon the roof deck? A cricket might be strategically placed alongside the chimney, nearer to the roof’s pinnacle.
The cricket comprises two wooden components, joined at a ridge resembling a gable roof. This ridge runs perpendicular to the roof’s own ridge.
When rainwater courses down the shingles, the cricket guides it away from the chimney’s vicinity. Absent a cricket, vertically oriented step flashing can be fitted, extending six inches up the chimney’s side, yielding similar outcomes.
Chimneys mandate specific flashing techniques. Step flashing, cap flashing, and corner flashing can be skillfully applied. For the chimney deck, a waterproof underlayment such as CertainTeed’s Winterguard® emerges as the optimal base layer.
Exhaust pipes create openings through which water can infiltrate. A fitting solution entails the installation of a snug preformed flashing flange.
This flange envelops the pipe like a skirt, featuring a broad, seamless lower section that channels water away from the pipe’s base, down the shingles.
The roofing professional must incise a shingle over the vent, positioning it below the flange, augmenting the protective layer. Asphalt roofing cement comes into play to seal any hidden crevices.

Roof Design and Formation

  • Challenge: Vulnerable valleys, suboptimal ventilation
  • Solutions: Underlayment, flashing, installation methods, ventilation (additional ridge and eave vents might be requisite)
Valleys form a common aspect of many roofs. Water coursing down the roof converges into these valleys, eventually making its way to the gutters. This represents the desired functionality of your roof!
Valleys warrant reinforcement to ensure peak performance. Waterproof underlayment should be affixed to the deck within these valleys, forging a seamless foundational layer.
Additionally, metal valley flashing needs to be positioned along these valleys. The installation can manifest as either open or closed, contingent on the chosen shingles.
Furthermore, weaving the shingles can provide an extra layer of safeguarding for these exposed areas.
Ventilation requisites hinge upon roof design and formation. Unique roof attributes influence ventilation needs. Each deviation from the flat roof surface engenders zones where airflow might encounter obstruction. Typically, intake and exhaust vents suffice, even for intricate features like turrets.

Distinctive Architectural Elements

  • Challenges: Proper underlayment and shingle installation, safeguarding against feature-related leaks
  • Solutions: Tailored installation methods, specialized flashing techniques
Roof replacements warrant heightened focus on unique elements such as turrets, cones, and dormers.
Among these, dormers represent the most prevalent. Commonly found on Cape Cod- and Arts and Crafts-style residences, dormers consist of vertically protruding windows set against a sloped roof. Gabled and shed dormers are typical, while hipped, eyebrow, and segmental variations also exist.
Dormer sides form vertical walls akin to chimneys. Sidewalls incorporate waterproof underlayment and step flashing to prevent water infiltration.
Exceptional diligence is necessary during shingle installation on dormer rooftops. Custom shingle cuts, distinct installation methods, and ridge caps along the dormer ridge collaboratively ensure both aesthetic appeal and effective waterproofing.
Cones and turrets represent rarer (and more intricate) roofing features. Flourishing during the Victorian Era, these elements evoke medieval castle aesthetics.
Roof replacement tasks for cones and turrets prove to be exceptionally labor-intensive. Roofing products manufacturer CertainTeed approximates that handling these features demands five times the labor required for a standard roof.
“The incremental cost for features like turrets, cones, or tower-shaped roofs is attributed to the labor-intensive nature,” explains Jeff Frantz, Certainteed Mid-Atlantic Territory Manager. “These roofs necessitate specialized setup for new roof installation, including unconventional scaffolding and distinct shingle application.”
The challenge with such features lies in adorning conical bases with flat, rectangular shingle strips. Cone circumferences exhibit variability, requiring tailored cuts and installations to ensure shingles remain flush on curves.
CertainTeed advocates for trapezoidal shingle shapes, tapering towards a narrower width as they ascend the cone. A metal cap, typically made of copper, is secured atop the cone using roofing cement. This cap seals the cone’s tip, where deck and shingle seams converge.
