Flat and Low-Slope Roofing in Syracuse, NY
Before anything else on a city porch roof, measure the pitch.
Flat Roofs in Syracuse
Before anything else on a city porch roof, measure the pitch. Section R905.2.2 permits asphalt shingles only on slopes of two units vertical in 12 units horizontal or greater, and requires double underlayment on slopes from 2 in 12 up to 4 in 12, so a shallow porch that has been shingled twice may have been the wrong assembly on both occasions and the leak is a specification problem rather than a workmanship one. In a city where 43.1 percent of 67,601 housing units were built in 1939 or earlier, front porches, bay tops and rear additions with almost no fall are on street after street, and the number on the pitch gauge decides whether the job is a membrane job or a shingle job.
What to weigh before you book
The second number that matters is how wet the existing assembly is. The code bars laying a new covering over an existing one that is water soaked or has deteriorated to the point that it is no longer an adequate base, and on a low-slope roof that has been ponding for years that condition is common rather than rare, because saturated insulation and boards do not dry out under a new membrane, they simply stop being visible while they keep rotting. Have the assembly opened and probed before the price is fixed. On paperwork the city is straightforward: the Central Permit Office lists Roof as a residential construction permit type in its own right with its own online application, so this work is filed the same way a full replacement is and a quote with no permit line is an incomplete quote.

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.

Frequently Asked Questions
Can I just shingle the porch like the rest of the house?
Only if the measured slope is at least 2 in 12, and between 2 in 12 and 4 in 12 the code wants double underlayment. Below that, shingles rely on water running off faster than it can work back under the laps, which under standing snow it will not. Measuring is the cheapest step in the job and it decides everything after it.
Does a porch roof need a city permit?
The city treats Roof as its own residential permit type with its own online application, so plan for the filing rather than hoping the size of the job makes it unnecessary. An unpermitted roof can surface later at sale or at a rental inspection, which is an expensive way to save a form.
