Specialized Expertise for Montgomery County’s Flat Roofs
Flat and low-slope roofs require a different level of precision than standard shingle systems. Whether you have a contemporary home, a rowhouse, or a flat-roof addition over a garage or porch, ELR Roofing L.L.C. provides the specialized membrane systems needed to keep your property dry. As an Owens Corning® Roofing Preferred Contractor with extensive experience in commercial-grade residential solutions, we bring professional-tier oversight and 5-year workmanship guarantees to every project we manage.
Our Flat & Low-Slope Solutions

- Liquid-Applied Coatings: Extend the life of your existing flat roof with advanced silicone or elastomeric coatings that seal leaks and improve energy efficiency.

Is your flat roof holding water?
Flat roofs in Montgomery County face extreme challenges, from heavy snow loads to stagnant water during spring rain cycles. Most “standard” roofers treat flat roofs as an afterthought, leading to premature seam failure and interior water damage.
Benefits of an ELR Flat Roof System
- Energy Efficiency: White reflective membranes can significantly lower the temperature of your home during humid PA summers.
- Leak-Free Seams: We utilize modern heat-welding or specialized adhesives that are far more durable than the “peel-and-stick” methods used by budget contractors.
- Low Maintenance: Our systems are designed to be “set and forget” with minimal required upkeep beyond regular gutter cleaning.
- Ponding Water Resistance: We use materials engineered to withstand standing water, a common issue on older Schwenksville and Collegeville homes.
- Space Optimization: Transform a flat area into a functional space with impact-resistant membranes that support future deck installations.
The ELR Difference: Detail-Driven Results
Flat roofing is 90% about the details. We don’t take shortcuts on the areas you can’t see.
- Substrate Inspection: We fully remove old layers to inspect the wood deck for rot or moisture saturation—ensuring a solid foundation for the new membrane.
- Tapered Insulation: If your roof doesn’t drain properly, we can install custom-cut tapered insulation to create a slope and direct water toward your drains.
- Heavy-Duty Flashing: We use reinforced termination bars and specialized flashing at all wall and chimney transitions to prevent “peel-back” during high winds.
- No-Mess Cleanup: From removing heavy asphalt layers to the final magnetic sweep, we ensure your property remains spotless.
