Proven membrane systems engineered for Riverside's relentless sun. From single-ply TPO to time-tested EPDM, Gary installs flat roofs that stay watertight for decades.
Flat and low-slope roofs present unique challenges that standard shingle systems simply cannot address. Water does not shed off a flat roof the way it rolls down a pitched one. Every seam, every penetration, every drain must be perfectly sealed or you end up with ponding water, hidden leaks, and structural damage that compounds fast in Riverside's desert heat.
Gary has been installing and repairing flat roof systems across the Inland Empire for over three decades. He understands that the "flat roof" label covers a broad range of structures: from commercial warehouses and strip malls to residential room additions, patio covers, and modern architectural homes with parapet walls. Each one demands a system matched to its specific load, sun exposure, and drainage profile.
TPO has become the gold standard for commercial and residential flat roofing in Southern California, and for good reason. Its white reflective surface bounces back solar radiation, keeping buildings cooler and cutting energy bills measurably during Riverside's 100-degree summers. TPO membranes are heat-welded at the seams rather than glued, creating a monolithic, watertight bond that gets stronger over time. Gary installs TPO in 60-mil and 80-mil thicknesses depending on traffic expectations and warranty requirements.
EPDM is the rubber roofing membrane that has been protecting flat roofs since the 1960s. It has the longest real-world track record of any single-ply system, with documented installations still performing after 40-plus years. EPDM handles Riverside's extreme UV exposure and temperature swings without cracking or splitting. Gary typically recommends EPDM for structures where proven longevity matters more than reflective energy savings, including storage buildings, detached garages, and industrial facilities.
For roofs that take foot traffic or heavy equipment loads, Gary often specifies modified bitumen. These multi-layer torch-applied or self-adhered systems create a thick, resilient surface that resists punctures from HVAC technicians walking the roof, dropped tools, and hail. Modified bitumen also works well as an overlay on aging built-up roofs when a full tear-off is not cost-justified.
The number-one failure point on any flat roof is poor drainage. Standing water accelerates membrane breakdown, breeds algae, and adds destructive weight. Gary evaluates every flat roof project for existing slope, drain placement, and scupper conditions before recommending a system. When the existing slope is insufficient, he installs tapered insulation boards to create positive drainage paths that move water to the roof edge or internal drains reliably.
Every flat roof Gary installs follows a rigorous four-step process built from 35 years of field experience on Inland Empire rooftops.
Gary inspects the existing deck, drainage paths, insulation, and structural supports. He photographs problem areas and measures precise dimensions for material ordering.
Based on roof use, budget, and sun exposure, Gary recommends TPO, EPDM, or modified bitumen. He explains the trade-offs honestly so you choose what fits your building.
Old material is stripped to the deck. Damaged decking is replaced. Tapered insulation is laid for drainage, then the membrane is mechanically fastened and heat-welded at every seam.
Gary flood-tests critical areas, inspects every seam and flashing, and walks you through the completed roof. He provides maintenance guidelines and full warranty documentation.
Flat roofing demands specialized knowledge that most residential contractors simply do not have. Gary has spent decades mastering membrane systems.
Gary installs TPO, EPDM, modified bitumen, and built-up systems. He matches the membrane to your building instead of selling the one system he happens to stock.
Every TPO seam is hot-air welded, not glued. Welded seams create a permanent bond that strengthens over time and eliminates the adhesive failures that plague cheaper installations.
Gary corrects slope problems with tapered insulation and proper scupper placement before laying any membrane. Solving drainage first prevents 90% of future flat roof failures.
Gary and his crew handle every flat roof project personally. No subbed-out labor, no day workers, no one learning on your building. The same hands that measure your roof install it.
If a patch or coating can extend your flat roof another ten years, Gary will tell you. He does not push full replacements to pad the invoice. That anti-upsell philosophy has kept his reputation spotless.
When storm damage is involved, Gary handles your insurance company directly. He documents the damage, files the claim paperwork, and negotiates scope so you are not left covering gaps.
Get Gary's honest assessment. No high-pressure sales, no unnecessary tear-offs. Just the straight answer your building needs.
Gary will assess your flat or low-slope roof personally, explain your options in plain language, and give you a written estimate with no hidden fees. Most estimates are completed within 48 hours of your call.
