PROJECT SPOTLIGHT.

Multi-Family Shingle Roofing Project with Complex Slope Transitions

Phoenix Roofing Services completed a full shingle roof replacement at Siena Townhomes in Celebration (Kissimmee), Florida, totaling approximately 13,600 square feet across one multi-family building.

While this project may appear straightforward from the ground, it presented several technical challenges that required careful planning and system-specific installation methods — especially due to the building’s transition from low slope to steep slope roof planes.

Managing Low Slope to Steep Slope Transitions

One of the defining features of this project was the roof geometry. Portions of the building transitioned from approximately 4:12 pitch (low slope) to 9:12 pitch (steep slope).

These transitions are critical in multi-family roofing projects because:

• Low slope areas are more vulnerable to wind-driven rain

• Water flow concentrates differently at slope changes

• Underlayment requirements vary by pitch

• Shingle fastening patterns must be adjusted per manufacturer specifications

To properly address these conditions, our team installed Polyglass self-adhered underlayment in low slope and high water flow areas. Self-adhered underlayments provide superior secondary waterproofing protection, especially in areas where water exposure is more likely.

On steep slope sections, installation followed manufacturer fastening requirements to ensure proper wind uplift resistance and long-term performance in Florida’s climate.

CertainTeed Landmark Shingle System

The selected roofing system included CertainTeed Landmark architectural shingles, a widely recognized and trusted product in the multi-family and HOA roofing market.

Landmark shingles offer:

• Dimensional architectural appearance

• Proven wind resistance performance

• Manufacturer-backed warranty coverage

• Consistent color and curb appeal for community-wide installations

For condominium and townhome communities in Central Florida, architectural shingles remain one of the most cost-effective and reliable roofing systems when installed correctly and paired with proper underlayment and flashing details.

Flashing Replacement & Firewall Upgrades

In addition to the shingle installation, this project included:

• Full flashing replacement at roof-to-wall transitions

• Terminating wall repairs

• Installation of fire-resistant plywood at firewall separations

Multi-family buildings require special attention to fire separation assemblies and wall transitions. Addressing these details during roof replacement ensures not only waterproofing integrity but also compliance with building code requirements.

Why Detail Matters in Townhome Roofing

Townhome and condominium roof replacements are more complex than typical residential homes. Shared walls, fire separations, slope transitions, and community aesthetic standards all require a disciplined, technical approach.

At Phoenix Roofing Services, we specialize in multi-family and HOA roofing projects throughout Celebration, Orlando, Winter Park, and Central Florida, providing:

• Manufacturer-compliant installation

• Proper underlayment selection based on slope

• Code-conscious detailing

• Clear communication with property managers and boards

Projects like Siena demonstrate how thoughtful planning and system-specific installation create long-term value for communities.
