Flat and Low-Slope Roofing in East Syracuse, NY

Rear additions and full width front porches are where this village keeps its low-slope roofs, and with 54.0 percent of the housing built in 1939 or earlier they have been surfaced and resurfaced more times than anyone can now count. Rolled asphalt over built-up over plank decking is a routine find.

Local Context

Flat Roofs in East Syracuse

Rear additions and full width front porches are where this village keeps its low-slope roofs, and with 54.0 percent of the housing built in 1939 or earlier they have been surfaced and resurfaced more times than anyone can now count. Rolled asphalt over built-up over plank decking is a routine find. That history is the problem, because a new covering may not be laid over an existing one that is water soaked or has deteriorated to the point that it is no longer an adequate base, and a roof that has been holding standing water through repeated winters is very often exactly that. Wet insulation does not dry out under a fresh membrane. It just stops being something anyone can see.

Deciding

What to weigh before you book

So the first spend on an East Syracuse flat roof is investigation rather than material: open it, find out how many coverings are there, and find out whether the boards and insulation are sound. The second decision is drainage, which on these buildings usually means where the main slope sends its water. A steep roof shedding onto a small addition roof delivers meltwater and sliding snow from a far bigger area than the low-slope section itself, and if a downspout from above discharges onto it, redirecting that discharge sometimes solves the whole problem for a fraction of a re-cover. On filing, the village Buildings and Codes Department at 204 North Center Street does not name roofing separately in its published permit list, so ask the Village Clerk's Office, open 7:30 am to 4:00 pm on weekdays, whether the scope counts as an alteration.

The Work

What Flat Roofs involves

A flat or low-slope roof is a different assembly from the sloped roof above it, and in Onondaga County it does a harder job. It does not shed snow, so it carries the season's load in place, and water that cannot run off freezes and thaws in it repeatedly through the winter. These roofs are everywhere on the older housing here: front porches, rear additions, dormer tops, bay projections and the flat sections of Victorian and early twentieth century houses in the villages and the city. The Village of Liverpool singles them out, requiring a building permit for performing any work on a flat roof, including but not limited to hot tar or rubber membrane. The systems are single ply membrane, modified bitumen and, historically, built-up hot tar, and the decision between them is usually made by the drainage rather than by the material.

Questions

Frequently Asked Questions

Can a new membrane go straight over what is already there?

Not if what is there is saturated or has broken down to the point of not being an adequate base, and not where two or more coverings already exist. On this housing stock both conditions turn up regularly, so the layers should be checked and the insulation probed before anyone quotes a re-cover price.

Water sits on my addition roof for days after a thaw. Is that a defect?

Standing water is treated as a fault rather than a cosmetic issue, because it is the thing that finds seams, laps and terminations while the temperature keeps crossing freezing. The fix is usually in the falls and the outlet rather than in the choice of membrane, which is why drainage gets designed first.
