You know that sinking feeling when you spot another water stain on your ceiling. The frustration of calling contractor after contractor, only to have the same leak show up again after the next storm.
Here’s what changes when your flat roof is done right. No more emergency calls when it rains. No more buckets strategically placed around your home. No more wondering if this repair will actually hold.
Your flat roof becomes what it should be – invisible protection that just works, year after year, through Sea Cliff’s harsh coastal weather and Long Island’s temperature swings.
We’ve spent over 22 years solving flat roofing problems that other contractors can’t figure out. We’re the family-owned company Sea Cliff homeowners call when they’re tired of temporary fixes.
We understand something most contractors miss – flat roofs fail at the details. The flashing where your roof meets the wall. The seams that weren’t properly welded. The drainage that was never quite right from day one.
That’s why we focus on getting these critical areas perfect the first time, using techniques like molecular welding for TPO seams and proper membrane installation that extends behind siding layers where other contractors take shortcuts.
First, we inspect your entire roof system, not just the obvious problem areas. We check drainage, look for membrane deterioration, and identify the flashing issues that cause most flat roof failures.
Next, we remove damaged materials completely – no patching over problems that will resurface later. We inspect and repair the deck if needed, then install proper insulation and drainage improvements.
The installation itself uses commercial-grade materials like TPO or EPDM rubber, with seams that are molecularly welded for permanent bonds. We extend membranes behind siding layers and create redundant flashing systems that won’t fail when Sea Cliff’s coastal winds and salt air test your roof.
Finally, we test the entire system and show you exactly what we’ve done, so you understand why this repair will be the last one you need.

Sea Cliff’s location puts unique demands on flat roofing materials. Salt air accelerates deterioration. Coastal winds create uplift forces. Temperature swings cause expansion and contraction that break weak seams.
That’s why we use TPO and EPDM membranes designed for these conditions. TPO offers superior heat welding capabilities – we’re talking about seams that are molecularly bonded, not just glued together. EPDM provides flexibility that handles building movement without cracking.
For commercial applications or larger residential flat roofs, we often recommend modified bitumen systems that combine the durability of traditional built-up roofing with modern installation techniques. These systems include multiple layers of protection and reflective coatings that reduce energy costs.
Every installation includes proper edge details, overflow drains to prevent ponding, and flashing systems that account for Sea Cliff’s weather patterns. Because in our experience, it’s not the membrane that fails first – it’s usually the details around penetrations and perimeter areas where water finds its way in.
A properly installed flat roof in Sea Cliff should last 15-25 years, depending on the material and maintenance. EPDM rubber roofing can exceed 30 years with proper care, while TPO systems typically provide 20-25 years of reliable service.
The key factor isn’t just the material – it’s the installation quality and how well the roof handles Sea Cliff’s coastal environment. Salt air, UV exposure, and temperature fluctuations all affect lifespan, which is why we use commercial-grade materials and installation techniques that account for these local conditions.
Regular maintenance extends roof life significantly. Simple tasks like clearing debris from drains and checking for membrane damage can prevent small issues from becoming major problems.
In our experience, almost all flat roof leaks come from improperly installed flashing around penetrations and wall connections, not membrane failure. This includes areas where pipes, HVAC units, or other equipment penetrate the roof surface.
The second most common cause is standing water from poor drainage. When water sits on a flat roof for more than 48 hours, it begins breaking down the membrane and can void manufacturer warranties. Sea Cliff’s occasional heavy rains make proper drainage critical.
Coastal winds also create unique challenges by lifting membrane edges and putting stress on seams. That’s why we use mechanical fastening systems and ensure all edges are properly secured and sealed against wind uplift.
If your flat roof is less than 15 years old and the leaks are isolated to specific areas, targeted repairs often make sense. However, if you’re dealing with multiple leak points, widespread membrane deterioration, or recurring problems, replacement is usually more cost-effective long-term.
We can often tell during inspection whether repairs will hold or if you’re just delaying the inevitable. Signs that point toward replacement include: multiple failed repair attempts, membrane shrinkage, widespread blistering, or structural issues with the roof deck.
The good news is that modern flat roofing materials and installation techniques are far superior to what was available even 10 years ago. A new flat roof installed correctly should give you decades of trouble-free service.
TPO (Thermoplastic Polyolefin) is white or light-colored, reflects heat well, and uses heat welding for seams – creating molecularly bonded joints that are extremely strong. It’s excellent for larger roofs and commercial applications.
EPDM is black rubber that’s very flexible and comes in wider sheets, reducing the number of seams needed. It’s particularly good for roofs with many penetrations or irregular shapes, though seam installation requires more precise conditions.
Both materials perform well in Sea Cliff’s climate, but TPO’s reflective properties can reduce cooling costs, while EPDM’s flexibility handles building movement better. The choice often depends on your specific roof configuration and energy efficiency goals.
Proper drainage starts with the roof design – even “flat” roofs need a minimum slope of 1/4 inch per foot toward drains. When existing roofs have drainage problems, we can install tapered insulation systems to create proper water flow.
We also ensure drain locations are adequate for the roof size and install overflow drains as backup protection. Scuppers (wall openings) provide additional drainage and prevent water from backing up if primary drains become clogged.
Regular maintenance is crucial too. Keeping drains clear of debris, checking for membrane settlement that creates low spots, and addressing small drainage issues before they become major problems. Standing water is a flat roof’s worst enemy, so we design every system to move water off quickly and efficiently.
Yes, we provide comprehensive warranties that cover both materials and workmanship. Material warranties from manufacturers like GAF or Firestone typically range from 15-30 years depending on the system chosen.
Our workmanship warranty covers installation defects and ensures that if problems arise from our work, we’ll return to fix them at no charge. We’ve been serving Long Island for over 22 years, so you can trust we’ll be here to honor our warranties.
The key to any roofing warranty is proper installation and maintenance. We provide detailed care instructions and can set up regular maintenance programs to keep your warranty valid and extend your roof’s lifespan well beyond the warranty period.
