A sloped assembly functions by shedding rainfall rapidly — the pitch does most of the job, and overlapping pieces absorb a degree of imperfection.
A low-pitch assembly has not one of those helps. Water leaves unhurriedly, stands at whatever point the slope goes wrong, and the surface is a single membrane where the any weld amounts to a possible entry location. Low-slope roofing is a different craft from pitched roofing, and companies that treat the two as the same trade generate precisely the results you would anticipate.

The Systems and Which Each Covers
- Thermoplastic polyolefin. The seams are thermally welded, which produces a bond as strong as the sheet on its own. Typically white, and that reduces summer thermal load noticeably. The most common specification on new low-slope work.
- EPDM rubber. A synthetic material, usually black. Joints are taped instead of fused, and that makes the seam quality precisely the governing variable. Exceptionally tough when installed well.
- Mod-bit systems. Asphalt membrane strengthened and applied in plies. Hard-wearing and accommodating of maintenance access, and that is worth having on a roof with equipment a technician has to reach.
- BUR. The traditional layered assembly — layers and asphalt built up across alternating courses. Genuinely still appropriate on specific buildings.
- Rubber slate systems. A different product entirely — specified where the look of stone is wanted but not its mass.
Drainage — the Whole Game
The word "flat" is a misnomer. A properly built so-called flat covering has an intentional fall toward the drainage points. Where the fall is wrong, rainfall ponds, and ponded rainfall amounts to the one most consistent forecaster of membrane breakdown.
Accordingly an assessment examines drains and scuppers for obstruction, the pitch to them, evidence of prior standing water — which leaves distinct marks long once it is gone — and if added equipment placed after the membrane was installed today blocks the designed drainage.
Where Flat Roofs Give Out
- Membrane seams. For a welded membrane, a cold joint stays shut through a year or two and subsequently lets go.
- Curbs and penetrations. Each vent, curb, and scupper. Rooftop units added later by an outside contractor is a very frequent cause.
- Edge metal and edge terminations. Where the sheet ends and gets mechanically secured. Wind works with the greatest force exactly at the perimeter.
- Puncture damage. Impact from objects, limb fall, or maintenance use on a sheet never intended to take that use. Walk pads are inexpensive protection.
Which Factors Determine Membrane Numbers
Membrane pricing rest on a different group of factors from steep-slope roofing:
- Removal against overlay. Certain old assemblies accommodate another layer on top of the previous. Plenty do not, and water-logged insulation beneath the old sheet rules it off the table.
- Board and tapered work. Building in slope using built-up board costs genuine expense, and that spend fixes the single largest cause of flat roof trouble.
- Attachment system. Point attached, fully glued, or ballasted. Design wind loading, deck construction, and the building height govern the choice.
- Penetration count. Every curb, roof drain, and stack is individual detail. A roof holding substantial mechanical plant is a considerably distinct job from a clear field of identical size.
The Ten-Year Workmanship Guarantee
Low-slope producers offer manufacturer system warranties, routinely conditional on the work by a certified contractor and on documented maintenance. Such requirements are real, and we'll say clearly precisely what each product demands of you to hold its coverage valid.
Separately from whichever manufacturer warranty applies, qualifying membrane projects through The Roofing Company include ten years of workmanship guarantee. A defect coming back to our welding inside that term is our cost to resolve.
Membrane Roofing in the Pennsylvania Winter
Snow load does not slide clear of this kind of covering. It remains, thaws during the day, freezes again overnight, and the resulting load is a good deal heavier than dry accumulation to the same height. Drainage that functions perfectly adequately in warm weather may end up blocked with ice solid in the cold.
This turns precisely two items count here more than they might somewhere to the south: overflow drainage so an iced principal drain doesn't flood the roof, and a look going into winter instead of once trouble arrives.
