A Roof With Almost No Slope
A roof with barely any pitch is a different design problem from the ordinary sloped kind, so shingles are never the answer. A flat roof gives little margin for error in the details, so it pays to hire people who work on flat roofs regularly.
The Systems You Will Hear About
The seams on thermoplastic sheets are fused rather than glued, which makes them strong, and the quality of the welds is the main concern. The big rolls of rubber cover large areas with few seams, and punctures can be patched with the same materials. Layered asphalt systems have been used for generations and are valued for redundancy, and the system is heavy compared with single-ply.
The Weak Points of a Level Roof
The open field of a membrane is usually the toughest part of the whole system, and a roofer should walk every foot of the edge. Cracked sealant at the top of a wall flashing is one of the most common sources of leaks, and redoing sealant is routine upkeep.
Ponding, Drains and Rain Bursts
Ponding is the condition of standing water on a roof, and it accelerates wear on any membrane, and a little care goes a long way. A new roof is the best time to correct drainage problems for good, and the improvement is permanent.
How Heat Wears a Low-Slope Roof
Ultraviolet light and heat are the main forces that age the surface of a low-slope roof in this region, and a reflective finish lowers that stress. A coating adds a protective layer and can seal small cracks and seams, and the preparation is as important as the product.
What Happens Around Machinery
A roof with many openings needs more maintenance than one with few, and replacing a worn collar is a quick job. Tools, ladders and dropped objects can cut a sheet, so care is required, and a plan for traffic keeps the roof sound.
What a Roof Can Still Do
Localized seams, flashings and punctures can be fixed without touching the rest of the roof, so ask to see where the water is getting in. These options depend on the condition of the insulation under the old surface, and the survey is worth the small cost. A new roof is also a chance to improve slope, drains and edges, and it should be planned rather than rushed.
Small Flat Roofs With Big Responsibilities
A level porch roof may look like a minor part of a house, yet it protects the walls and the ceiling beneath it just as a main roof does, and the wrong material on a flat roof will leak. Where a flat porch roof meets the wall of the main house, the membrane has to climb the wall and be capped so that water cannot run behind it, so look at the wall as well as the roof. A roof used as living space has to meet higher standards than one that nobody walks on, so involve the roofer early.
What Sits Between the Roof and the Ceiling
A flat roof has little or no attic, so the layers of the roof itself have to do the work that attic insulation and ventilation do on a pitched house, and the combination is worth planning. A moisture survey with a meter or an infrared camera can map the wet areas without tearing the roof apart, and the map is a useful record.
A Simple Maintenance Calendar
Photographs taken each year create a record that makes changes easy to see, and the work is quick. Noting the date and the weather when a leak appears helps the roofer find the cause, and it pays to think it through.
Wind, Edges and Fastening on a Level Roof
Gusts lift a flat roof from its edges and corners, where the pressure is highest, and a membrane that is not firmly attached there can peel back like the lid of a can, so ask how the edges will be attached. Stones that have been scattered by wind or foot traffic leave bare patches that expose the membrane to ultraviolet light, and the gravel does a great deal of quiet work. Surprises about extra details are the most common cause of disagreement over flat roof bids, and it is easy to overlook.
Skylights, Hatches and Vents on a Level Roof
Each opening is a separate detail, and each one should be listed in the written proposal, so ask how every opening will be handled. The seal around a pipe on a low-slope roof has to be formed to match the membrane, because a generic rubber boot will not bond to every type, and every opening is one more detail to watch. A drain bowl that is sealed to the membrane with a clamping ring and sealant keeps water from creeping under the sheet at the outlet, and a little care goes a long way.
Getting Specific About the System
Look for the manufacturer system and the type of seam, whether welded, glued or taped, and a careful contractor will explain every line. Find out how drainage will be addressed and whether tapered insulation is included, and notes help you compare.
Preparing the Property for a Membrane Job
Hot-applied and adhesive systems give off smells while they cure, so windows and vents near the work area are usually closed for a day, and tell the crew about pets and schedules.
Common Worries Before a Flat Roof Project
A flat roof is not doomed to leak, and one that is well built and looked after can serve a property for a very long time, and the answers are usually more reassuring than expected.
