Sealing and Waterproofing Around Skylight Curbs

Sealing and waterproofing are key steps for protecting skylight curbs from water damage. Choosing the right materials and methods ensures a tight, durable barrier that prevents leaks. Regular maintenance helps keep these seals effective over time.

High-Performance Sealant Options


We use sealants designed for flat roofing and skylight curbs that can handle extreme weather and temperature changes. Polyurethane and silicone sealants are popular because they offer strong adhesion and flexibility. These sealants resist cracking and shrinking, which are common problems with poor-quality products.


Our team applies sealants that are UV-resistant to avoid damage from sun exposure. We select products that fully bond to both metal and roofing membranes. This creates a continuous waterproof layer around the curb, minimizing the risk of water infiltration.

Techniques for Leak Prevention


Proper sealing starts with a clean and dry surface. We carefully remove all dirt, old sealant, and debris before applying new materials. This ensures better adhesion and longer-lasting protection.


We seal all joints and seams around the curb with multiple layers when needed. Flashing tape is often combined with liquid sealants for extra strength. We pay special attention to corners and edges, where leaks most often begin.

Long-Term Maintenance Solutions


Regular inspections of skylight curbs are crucial to catch early signs of wear or damage. We recommend checking seals twice a year and after severe storms.


For lasting results, we suggest scheduled resealing every 5 to 7 years depending on sealant type and weather conditions. Our team also handles prompt repairs to cracked or separated sealant to avoid bigger problems. Proper maintenance helps extend the life of both the skylight and roofing system.

Our Skylight Curb Installation Process

We focus on precise measurements, quality materials, and careful mounting to ensure the skylight curb fits perfectly and seals tightly. Each step is designed to protect the flat roof from leaks and structural damage while supporting the skylight properly.

Site Preparation and Assessment

We start by inspecting the roof area where the skylight curb will go. This includes checking the roof’s condition, locating any damage, and measuring the space carefully. It’s important to confirm the roof can support the curb and skylight without risking leaks.


Next, we clear debris and old materials around the installation spot. We make sure the roof surface is clean and smooth for the best seal. We also verify the roof slope and drainage to prevent water buildup near the skylight.

Custom Curb Fabrication

We build the skylight curb to exact dimensions based on the measurements taken. Using durable materials like metal or wood treated for weather resistance ensures the curb lasts over time.


Our fabrication process includes cutting, assembling, and sealing edges to create a strong, water-tight frame. Custom cuts allow the curb to fit flush with the roof’s surface, minimizing gaps and extending the roof’s lifespan.

Professional Mounting Techniques

We place the custom curb on the prepared roof spot and align it precisely with the opening. Fastening is done with corrosion-resistant screws or nails to hold the curb firmly in place.


Next, we apply high-quality roofing sealant and flashing around the curb edges. This stops water from seeping under the curb. We finish by testing the seal to ensure no leaks can develop during rain or snow.
