Secure and Versatile Mounting for Any Pitched Roof
Promisteel's Pitched Roof Mounting System provides a secure, reliable, and versatile platform for installing solar panels on a wide variety of sloped rooftops. Designed with both strength and ease of installation in mind, our system ensures the long-term safety of your solar investment while preserving the integrity of your roof structure.
- Universal Compatibility for Diverse Roof Types
Our greatest strength lies in versatility. We offer a comprehensive range of components to match virtually any pitched roof surface. For industrial metal roofs, we have specialized, non-penetrating solar clamps for standing seam roofs and fixtures for trapezoidal profiles. For traditional buildings, we provide robust solar roof hooks for tile roofs and secure flashing kits for asphalt shingle roofs. This ensures a perfect fit and a secure connection every time.
- Engineered for 100% Waterproof Performance
We understand that protecting your building from water damage is non-negotiable. Our pitched roof solar racking is meticulously designed to maintain your roof's waterproof barrier. Our non-penetrating clamps for metal roofs attach directly to the seams without creating any holes. For installations requiring penetration, we use high-quality flashing plates and EPDM rubber gaskets to create a durable, multi-layered seal that provides complete peace of mind.
- Lightweight and Easy to Install
Constructed primarily from high-grade, lightweight aluminum, our system minimizes the additional load on your roof structure. The components, such as our universal solar mounting rails and pre-assembled clamps, are designed for intuitive and rapid assembly. This allows installation teams to work faster and safer, reducing overall project time and labor costs.
Tailored Solutions for Your Specific Roof
| Roof Type | Promisteel Solution & Key Component | Installation Method |
| Standing Seam Metal Roof | Standing Seam Solar Clamps | Non-Penetrating: Clamps attach directly to the raised seams. No drilling required. |
| Trapezoidal/Corrugated Metal Roof | L-Feet with Hanger Bolts | Penetrating: L-feet are securely fastened to the roof purlins with self-tapping screws and EPDM washers for a watertight seal. |
| Tile Roof (Spanish, Clay, Flat) | Stainless Steel Tile Hooks | Penetrating: Hooks slide under the tiles and are secured to the roof rafters. Tiles are replaced to cover the hook arm. |
| Asphalt Shingle Roof | Flashing Mounts with L-Feet | Penetrating: An aluminum flashing plate is installed under the shingles, creating a waterproof seal around the attachment point. |
The features of the inclined roof photovoltaic support system include:
● Adjustable angle: The bracket system can adjust the angle of the solar panel according to the slope and direction of the roof to maximize the use of the energy of the sun.
● Good stability: The sloping roof photovoltaic support system adopts a stable frame structure and a safe fixing method, which can resist the influence of wind, rain, and other weather factors.
● Strong applicability: suitable for various types of roofs, such as concrete tiles, quartz tiles, asphalt tiles, metal tiles, color steel tiles, etc. The bracket system can also accommodate different slopes and orientations.
● Easy installation: The components of the bracket system can be prefabricated and only need simple assembly and fixing during on-site installation, which reduces the difficulty and time of on-site processing and construction.
● Easy maintenance: The materials used in the bracket system are corrosion-resistant and durable, which can reduce the frequency of maintenance and replacement and save maintenance costs.
● Increase the value of the house: Installing a sloped roof photovoltaic mounting system can increase the value and sustainability of the house.
FAQ
Q1: Will installing a solar mounting system on my pitched roof cause leaks?
A1: This is a primary concern, and our systems are engineered specifically to prevent it. For metal roofs, we offer non-penetrating solar clamps that attach directly to the seams without any drilling. For all other installations, we use high-quality flashing and EPDM seals to create a durable, multi-layered waterproof barrier around every attachment point, ensuring 100% waterproof integrity.
Q2: How do I know which components are right for my specific roof type?
A2: Our team will guide you. You can refer to our solutions table above, but the best way is to provide us with your roof type (e.g., standing seam metal, clay tile, asphalt shingle) and, if possible, some photos. We will then recommend the precise set of components, such as solar roof hooks for tile or specific clamps for your metal roof profile, to ensure a perfect and secure fit.
Q3: Is the system heavy? Will it damage my roof structure?
A3: Our pitched roof solar racking is primarily constructed from high-grade, lightweight aluminum. This material is chosen for its excellent strength-to-weight ratio, which minimizes the additional load on your roof. We always recommend a structural assessment for older buildings, but in most cases, our system's weight is well within the roof's load-bearing capacity.
Q4: Can I install solar panels on a slate or asbestos roof?
A4: We generally do not recommend installing solar panels on slate or asbestos roofs due to their fragile or hazardous nature. Slate tiles can easily crack during installation, and working with asbestos requires specialized, licensed professionals. We would be happy to discuss alternative solutions, such as a ground-mounted system, if you have this type of roof.
