Commercial Roofing in Tottenville, Staten Island, NY

Water borders Tottenville on three sides, and many small factories once lined the Arthur Kill shoreline, though most no longer operate. In 2012 Sandy destroyed the Coral Bay Cafe at Tottenville Beach, a reminder of how exposed the shoreline is, and the storm's gusts reached 80 mph. With water all around, wind of that kind reaches every edge, so the perimeter is the first concern on every building. Edge metal is tried by hand, sealant at laps is probed, fastener spacing at corners is measured and rust below fasteners is noted. Repairs start at the edge, because the edge gives way first, and the field membrane peels away from it.

The small factories that once lined the Arthur Kill shoreline were light industrial buildings, and some have been reused for storage, shops and small businesses. Their roofs are often layered corrugated metal or built-up membranes patched many times. Roofs of that age hold water, and the structure may be lighter than a modern deck.

We cores are pulled, wet insulation is scanned and the deck is tested. A coating suits a sound metal roof once rust is treated and fasteners are replaced. Metal roof retrofit adds a new panel over an old one when the structure allows. If cores show saturated layers, sections come off, and the replacement is phased so the business keeps running. The report shows the evidence and prices each option for the same roof.

A first walk on any of these roofs follows one order. Drains first, since a clogged drain changes how every other defect behaves. Then every penetration, bracket and curb, then the seams and laps across the field, then the parapet, coping and edge metal. On a metal roof we probe fasteners and laps by hand and look for rust streaks below screw rows. A scan after sunset maps wet insulation on membrane roofs. Every finding gets a photograph and a repair class, and the owner sees what can wait and what cannot.

Many small flat roofs depend on a single drain. When it clogs, water backs against the parapet. A drain with no overflow had no margin when Ida's rain brought on a flash flood emergency in September 2021, and spring, the wettest season in a city that takes in about 49.5 inches of precipitation a year, tests drains again every year. Strainers are cleared and photographed, leaders flushed and slope measured; overflow scuppers go in wherever the parapet allows. Drain and scupper work is the least expensive repair on a small roof and the one that most often heads off the next call. Water standing two days after rain can be a drain, a leader or a settled deck at fault.

Every roof gets its own page of photographs, a rating, scan results and a repair list ranked by urgency with prices, while a summary puts the buildings in order of risk. Each visit adds a dated entry, so after a storm the same record shows what changed, and an owner spends less time proving what the wind did and more time fixing it. Price on a small commercial roof moves with wet insulation, penetration count, access and system, and each of those is named so a repair, a coating and a replacement can be compared for the same building. Temporary protection is staged ahead of storm season for roofs that cannot take water, material for emergency patches is kept ready, and each owner receives the crew list for after-hours calls before the season opens.

Older buildings carry patches from many hands, so the log marks every earlier repair it can find. A photograph of the old patch, a note about its condition and a plan reference tell the next crew whether to trust it or replace it. Over several visits that history shows where water keeps returning.
