All Weather Seal delivers permanent residential protection across Mid-Michigan with advanced CertainTeed asphalt architectural systems. In 2026, premium asphalt shingles hold a dominant 75% market share for residential roofing because they handle extreme weather without the structural warping common in alternative systems, securing your home for a half-century.
Mid-Michigan homeowners trust All Weather Seal because we eliminate the vulnerabilities of regional weather through precision installation and heavy-duty materials. We do not cut corners with cheap underlayments or standard retail-grade shingles. Our factory-certified crews build complete, integrated roofing systems designed specifically to withstand the brutal freeze-thaw cycles seen in Flint, Lansing, and Brighton.
Look, the reality is that Michigan weather destroys average roofs. From rapid thermal cycling to heavy winter snow loads, your roof deck takes a beating every season. Here’s the kicker: we don’t just replace your shingles; we upgrade your entire structural defense.
Every project strictly adheres to or exceeds local building codes across Genesee, Ingham, and Livingston counties.
Our installers are dedicated specialists trained in ventilation balance and leak prevention.
We provide clear, transparent pricing down to the last penny, with no hidden fees or surprise change orders.
When you replace a roof, you want to do it once and know it’s done right. That’s why we focus on 50-year CertainTeed systems. They are built to hold up through years of tough seasons, keeping your attic dry and your home protected for the long haul.
Most standard shingles start curling, cracking, or losing their protective granules after just a few rough winters and hot summers. Our heavy-duty systems avoid that breakdown altogether. They use multiple reinforced fiberglass layers and dense asphalt to absorb heavy impacts, stay firmly sealed against high winds, and hold their shape year in and year out.
Beyond the protection, they give your house that deep, dimensional curb appeal that looks great from the street. You get a reliable, high-performing roof that quietly does its job so you don’t have to worry about it every time a storm rolls through.
Landmark® PRO offers an upgraded architectural profile featuring Max Def colors for exceptional visual depth. Engineered with two laminating layers of high-strength fiberglass, it provides heavy-duty defense against the elements. Highland Slate® delivers the rugged, chiseled look of real natural slate quarried from the earth, utilizing individual premium shingle tabs to create a striking texture without the massive weight or cost of stone.
Landmark® ClimateFlex® combines classic architectural styling with SBS-modified polymer bitumen. This creates a flexible, rubberized shingle that absorbs the energy of heavy hail impacts easily. Northgate® ClimateFlex® represents the peak of cold-weather performance. Its specialized rubberized formula allows the shingle to remain pliable and crack-resistant even when installed in freezing winter temperatures, earning the industry’s highest Class 4 impact resistance rating.
Belmont® perfectly mimics the classic look of natural slate with authentic shadow lines and stepped edges, backed by advanced fiberglass durability. Presidential Shake® TL features an ultra-thick, triple-laminate design that replicates the rustic charm of hand-split cedar shakes with massive dimensional depth. Carriage House® offers a unique, scalloped cut that evokes Victorian-era architecture, while Grand Manor® uses an asymmetrical design with deep tabs to deliver the ultimate multi-layered look fit for estate-style homes.

We choose CertainTeed roofing systems because their integrated structural design outperforms and outlasts alternative premium systems. The system relies on perfectly matched components, from heavy winter barriers to custom ridge ventilation, ensuring the shingle array bonds directly to the wood deck without structural stress.
Standard roofs struggle with Mid-Michigan’s high humidity and intense winter cold because poor ventilation and low-grade underlayment trap moisture underneath the shingles. Over time, that trapped dampness causes hidden wood rot along your roof deck before you ever notice a leak inside.
CertainTeed asphalt systems breathe naturally when paired with our balanced intake and exhaust ventilation systems.
The multi-layered shingles lay perfectly flat, absorbing solar heat to create a watertight thermal seal.
The seal won’t warp, buckle, or pull away from the roof deck over time.
Our structured installation protocol ensures your new roof performs flawlessly for decades:
We remove all old roofing materials down to the bare wood to inspect for hidden dry rot.
We install heavy-duty waterproof membranes along the eaves, valleys, and chimneys to stop winter ice dams.
We replace cheap felt paper with high-tensile synthetic underlayment for a second line of moisture defense.
We secure specialized starter strips along all edges to lock down the perimeter against high winds.
Our crews use correct multi-nail patterns driven straight into the structural rafters for maximum wind ratings.
We install custom ridge vents and inspect soffits to ensure continuous, mold-preventing airflow.
We sweep your entire property with heavy magnets to collect all debris before signing off.
Yes, our CertainTeed asphalt systems are engineered specifically to handle the extreme weather variations found throughout Mid-Michigan. Every shingle configuration features specialized seals that resist wind tear-offs up to 130 MPH, along with built-in algae defense to prevent ugly dark streaking.
When installed by a certified specialist like All Weather Seal, these premium systems easily last 50 years. The combination of multi-layered fiberglass and specialized weathering asphalt prevents the cracking and drying out common in standard retail shingles.
Landmark® PRO focuses on enhanced aesthetic depth and increased thickness over standard shingles. Northgate® ClimateFlex® incorporates SBS-modified rubberized asphalt, allowing it to flex and resist impact during cold winter weather.
Yes, they are highly effective. The Class 4 impact rating on our ClimateFlex® options prevents severe hail and falling ice from cracking the shingle mat, protecting your home and helping lower annual home insurance premiums.
The shingles utilize proprietary CertaSeal™ thermal-activated adhesive strips. This tight seal locks the shingles together into a single wind-resistant barrier that prevents blow-offs during intense storms.
Our warranty covers the full replacement cost of materials and labor if manufacturing defects occur. Because we are factory-certified installers, this coverage is fully backed by the manufacturer for long-term peace of mind.
Do not wait for a small roof leak to turn into an expensive structural repair. Protect your property with the Home of the 50-Year Shingle.
