ASPHALT ROOFING
A Better Roof Starts With What You Don’t See.
A roofing system is more than shingles. Sentinel installs complete asphalt roofing systems with disciplined attention to decking, water protection, flashing, ventilation and every critical detail beneath the finished roof.
Serving homeowners throughout Michigan’s Lower Peninsula.
ARCHITECTURAL SHINGLE ROOFING
Performance. Protection. Curb Appeal.
Your roof is one of the largest visual elements of your home—and one of its most important protective systems. Sentinel helps homeowners select an architectural shingle system based on the home, roof design, performance requirements and desired appearance.
We Recommend the Roof That Fits the Home.
There is no single roofing product that is right for every property. Roof geometry, ventilation, exposure, existing conditions, architectural style and homeowner priorities all matter. Our process begins with understanding the home before recommending a roofing system.
Serving homeowners throughout Michigan’s Lower Peninsula.
Engineered for Michigan’s Extremes.
Michigan roofing systems must withstand relentless freeze-thaw cycles, heavy snow loads, and high-velocity winds. Sentinel installs complete asphalt systems designed for thermal stability and moisture resistance. By integrating proper ice-and-water protection with balanced attic ventilation and precision-cut flashing, we ensure your roof performs as a unified barrier against the elements.
ARCHITECTURAL SHINGLES
Dimensional shingles provide a substantial, layered appearance while forming the primary weather surface of the roofing system. Available in a wide range of profiles and colors to complement the architecture of the home.
DESIGNER & PREMIUM SHINGLES
For homeowners looking for a more distinctive appearance, premium shingle options can provide enhanced dimensional profiles and architectural character.
COMPLETE ROOFING SYSTEM
The finished shingle is only one component. Sentinel considers underlayment, ice-and-water protection, flashing, ventilation, ridge and hip components, penetrations and roof-deck condition as part of the complete installation.
BUILT AS A COMPLETE SYSTEM
The Shingles Are Only the Part You See.
A roof’s long-term performance depends on the entire assembly. Sentinel evaluates and installs each critical component as part of one integrated roofing system — not simply a layer of shingles.
01
ROOF DECK ASSESSMENT
We evaluate the existing decking and identify deteriorated or compromised areas before the new roofing system is installed.
05
BALANCED VENTILATION
Proper intake and exhaust ventilation helps manage attic heat and moisture and supports the performance of the roofing system.
02
ICE & WATER PROTECTION
Critical areas receive appropriate protection against water intrusion caused by ice, wind-driven rain and vulnerable roof transitions.
06
ARCHITECTURAL SHINGLES
Quality architectural shingles provide the finished weather surface while delivering dimensional appearance and curb appeal.
03
SYNTHETIC UNDERLAYMENT
A secondary protective layer is installed beneath the finished roofing material as part of the complete roof assembly.
07
RIDGE & HIP PROTECTION
Ridge and hip components complete vulnerable transitions while providing a clean, professionally finished appearance.
04
FLASHING & PENETRATIONS
Valleys, walls, chimneys, plumbing penetrations and other transitions receive careful attention because these details are common sources of roof failure.
08
FINAL QUALITY REVIEW
Sentinel completes a final review of workmanship, critical details and jobsite condition before the project is considered complete.
