Water infiltration is one of the most common — and costly — forms of roofing damage in Colorado. That's why at Lianro Metal Roofs, we focus not just on roofing materials, but on the structural components that protect the most vulnerable parts of your roofing system.
Our professional roof valley installation and ice and water shield integration services are designed to provide enhanced protection against leaks, ice dams, and long-term water damage. Whether you're replacing an aging roof or building a new custom home, these components are essential for long-lasting roof performance.
We install valleys and moisture barriers as part of every full roof replacement — and we also offer them as standalone upgrades or repairs when damage is isolated or preventive improvements are needed.
A roof valley is the internal angle formed where two roof slopes meet. Because valleys naturally collect and channel water during rainfall or snowmelt, they're especially vulnerable to water infiltration, ice buildup, and wear over time.
Without proper flashing and underlayment, roof valleys can become weak points where leaks develop and materials deteriorate prematurely.
We fabricate and install both standard and custom valleys depending on your roofing material, slope complexity, and water flow needs.
Get Started TodayColorado's weather — with its heavy snow loads, frequent freeze-thaw cycles, and spring rainstorms — places stress on roof valleys like few other regions. If your roof valley is poorly designed or deteriorating, you may face:
Ice and water shield is a self-adhering waterproof membrane installed under the shingles in areas most prone to moisture intrusion — including eaves, valleys, ridges, and around penetrations.
This product forms a watertight barrier that protects the roof deck from snowmelt, ice damming, and wind-driven rain.
At Lianro, we fabricate roof valleys in-house and install them with precision to manage runoff, direct moisture away from critical joints, and integrate perfectly with your shingles or stone-coated steel roofing system.
We use ice and water shield on every new roofing system we install, following both manufacturer guidelines and Colorado best practices.
Seals around fasteners and decking to create a complete moisture barrier.
Adapts to nail punctures and temperature fluctuations for continuous protection.
Adds redundancy beneath the primary roof covering for enhanced protection.
Stops ice dams before they can cause damage to your roof structure.
Required by code in many Colorado municipalities for proper roof protection.
Used together with premium flashing and properly installed valleys, ice and water shield significantly extends the life of your roof.
Whether part of a full roof replacement or a standalone upgrade, we follow a detailed installation protocol to ensure long-term performance.
We ensure proper overlap, bonding, and integration to prevent any channel for water intrusion beneath the finished roof system.
Our roof valley and ice/water shield installation services are compatible with:
We tailor materials and flashing profiles to suit your roof's slope, drainage volume, and material type.
You may benefit from targeted valley or moisture barrier improvements if you've noticed:
Even without visible damage, valley upgrades and moisture barriers are valuable preventative improvements — especially in Colorado's climate.
We recommend including new valley flashing and full ice and water shield integration during:
The ideal time to upgrade your valley system and moisture barriers for complete integration.
Start with the right protection from day one on new construction projects.
Upgrade protection during roof expansions or architectural changes to your home.
When transitioning from basic shingles to architectural or steel roofing systems.
After weather events that may have compromised your roof's water protection.
Targeted valley repairs can be completed if the rest of the roof is still in good shape.
A roof valley is the area where two sloping sections of roof meet. These intersections naturally channel water down the roof, which makes them prone to leaks if not properly flashed and protected. Roof valleys require special installation techniques and materials to manage runoff and prevent moisture intrusion.
We install both:
The type of valley we recommend depends on your roofing material, slope, and regional conditions. In Colorado, open metal valleys are often preferred for better drainage in snow-heavy zones.
Ice and water shield is a waterproof membrane installed beneath your roofing material in vulnerable areas like eaves, valleys, and roof penetrations. It self-adheres to the roof deck and creates a watertight seal, preventing leaks caused by ice dams, wind-driven rain, and snow melt.
We install ice and water shield in:
It's a key part of modern roofing systems and helps stop leaks before they start.
In most Colorado municipalities, yes. Building codes often require ice and water shield along roof eaves or in any area where ice dams are likely to occur. At Lianro, we install it as a best practice on all full roof replacements — regardless of code — for added protection and peace of mind.
In some cases, yes. If your roof is otherwise in good condition, we can replace deteriorating valleys or install ice and water shield in specific problem areas. However, full integration is best done during a roof replacement or major upgrade for maximum protection and cost-efficiency.
Most do. Whether you're using IKO shingles or stone-coated steel, valleys must be either flashed or carefully woven to direct water away from the seam. Improperly installed valleys are one of the leading causes of roof leaks, especially in multi-slope or dormer-heavy designs.
We evaluate:
Based on those factors, we'll recommend either open metal valleys or shingle-integrated solutions with moisture barrier protection.
Look for:
If you notice any of these, schedule an inspection to prevent further damage.
