Weatherproof Sealing
Our sealing methods prevent water, air, and debris from penetrating the roof curb area. We use layered applications, including butyl tapes, flashing membranes, and liquid-applied sealants, tailored to flat commercial roofs. These materials bond tightly to metal curbs and the roofing surface.
Proper surface preparation is vital. We clean and prime surfaces to maximize adhesion and minimize shrinkage or cracking over time. Our teams ensure all seams and corners are sealed completely to eliminate weak spots where leaks can start.
Long-Term Leak Prevention
We aim to extend the life of installed roof curbs with maintenance-ready seals. Flexible sealants accommodate thermal expansion and contraction without breaking their waterproof barrier.
Fast-curing products reduce downtime, allowing HVAC systems to be operational quickly after sealing. We also inspect adjacent roofing components to confirm full integration and no risk of water migration beneath the curb.
Sealant Materials Selection
Choosing sealants depends on factors such as curb material, roof type, and environmental exposure. We prioritize elastomeric sealants for their flexibility and UV resistance.
Epoxy and polyurethane options are used in areas demanding high abrasion resistance and chemical stability. Each project involves analysis to match sealant properties to expected weather patterns and rooftop traffic for maximum protection.
Experienced Roofers
Our technicians hold certifications relevant to commercial roofing and HVAC installations. This ensures every project meets industry standards and local regulations. Experience matters. We have completed hundreds of commercial flat roof projects, including HVAC roof curb installation and sealing.
Quality Assurance
We implement a rigorous quality assurance process from start to finish. This includes detailed inspections, use of industry-approved materials, and adherence to manufacturer guidelines. Our sealing methods use high-grade products designed to withstand harsh weather and temperature shifts.
Local Expertise
Being based in Milwaukee means we understand the specific climate challenges here. Snow, ice, and humidity can affect roof performance, particularly around HVAC units. Our local experience allows us to recommend materials and designs suited for Milwaukee's environment. This minimizes potential leaks or damage.
FAQs on HVAC Roof Curb Installation & Sealing
We understand that proper HVAC roof curb installation and sealing impact the longevity and efficiency of your roofing system. Addressing common concerns helps clarify why precision and expertise matter.
How much does professional HVAC roof curb installation cost in Milwaukee?
Professional HVAC roof curb installation in Milwaukee typically costs between $1,200-$3,500 per curb, depending on size, complexity, and whether it's a new installation or retrofit. Custom fabricated curbs cost more than standard prefabricated options. Most commercial projects require multiple curbs, so total project costs often range from $5,000-$15,000 for a mid-sized commercial building.
Can damaged roof curbs cause water leaks in commercial buildings?
Yes, damaged roof curbs are a common source of water leaks in commercial buildings. When curbs crack, separate from the roof membrane, or have deteriorated seals, they create direct water entry points. This often leads to concealed moisture damage that can compromise insulation, deck materials, and interior spaces. Water infiltration through damaged curbs frequently causes problems that extend far beyond the immediate area of the curb itself.
How long does HVAC roof curb installation take for commercial buildings?
Standard HVAC roof curb installation typically takes 1-2 days per unit for commercial buildings. Simple prefabricated curb installations can be completed in 4-8 hours, while custom fabricated curbs or retrofits requiring structural modifications may take 2-3 days. Project timeline factors include building access, weather conditions, and whether the installation is part of a new construction or retrofit project.
Do commercial flat roofs in Milwaukee need special curb sealing for winter?
Yes, commercial flat roofs in Milwaukee absolutely require specialized winter curb sealing due to the region's extreme temperature fluctuations, heavy snowfall, and freeze-thaw cycles. Enhanced elastomeric sealants that maintain flexibility in sub-zero temperatures are essential. Additional flashing and ice/water shield membranes around curbs provide critical extra protection against ice dam formation and standing water issues common to Milwaukee's harsh winter conditions.
What are signs my commercial roof curbs need resealing or replacement?
Key signs your commercial roof curbs need resealing or replacement include visible rust or deterioration around curb edges, standing water near curbs, interior water stains below HVAC units, higher energy bills from air leakage, vibration or movement of HVAC equipment, visible gaps between the curb and roof membrane, damaged flashing, and sealant that has cracked, shrunk or pulled away from surfaces. Regular biannual inspections can help catch these issues early.
