Roof Repair for Rahway homes and buildings

Rahway's roofs fall into three groups: pitched shingle roofs on houses, low-slope rear sections on older homes and two-families, and flat roofs on downtown and industrial buildings. Leaks on the first group are usually at flashing and penetrations; on the second at the joint with the main house; and on the third at parapets, drains and seams.

We repair asphalt shingle roofs, membrane and built-up flat roofs, and the flashing at chimneys, walls, skylights, hatches and rooftop equipment. Before recommending work, we inspect the full roof and show you photos of the entry point rather than patching above a stain.

For downtown building owners, the parapet is often the real problem: cracked coping, open mortar joints and failed base flashing let water into the wall and onto the roof deck below. We treat the parapet and the roof as one system.

Rahway housing

Rahway's older neighborhoods near downtown hold late-1800s and early-1900s Victorians, foursquares and two-families, many with rear additions on low-slope roofs. Further out are 1920s to 1950s colonials, capes and bungalows, and post-war capes and ranches on the edges. Downtown has two- and three-story brick commercial buildings with flat roofs behind parapets, and newer mid-rise apartment buildings; industrial and commercial buildings add large flat roofs.

Weather & exposure

Rahway is low and fairly flat, closer to the coast than the county's western towns, so nor'easters bring sustained wind-driven rain. The Rahway River has flooded low-lying sections after major storms, which affects basements and chimney bases more than roofs. Mature trees shade older streets, and freeze-thaw works on downtown parapets and the brick chimneys of older homes.

Repair or replace? What we tell Rahway homeowners

A repair is the right choice when the roof is otherwise sound. Ask for photos of the problem and the fix. On older houses, a low-slope rear section is often worth replacing on its own even when the main roof is fine. When shingles are worn throughout or leaks keep appearing, replacement is the better investment.

Commercial and industrial owners benefit from routine flat roof inspections, because seam and drain problems are inexpensive to fix early. After a storm, photograph visible damage before cleanup; we can document storm damage with photos and a written assessment for an insurance claim.

Rahway Specifics

Roof problems we see in Rahway

Downtown parapet and coping leaks

Brick parapets on older commercial buildings lose mortar and coping joints and let water run down inside the wall behind the roof flashing. We repair coping, repoint the parapet and rebuild the base flashing where the roof turns up the wall.

Rear kitchen and porch additions

Older houses and two-families often have a low-slope rear section that was roofed with roll roofing or shingles at too shallow a pitch. We replace it with membrane and flash the wall properly where it meets the main house.

Wind-driven rain at flashing

Nor'easters push rain sideways into chimney and sidewall flashing that would stay dry in ordinary storms. We rebuild flashing in lapped metal rather than sealant so it sheds water from any direction.

Ponding on industrial roofs

Large flat roofs on industrial and commercial buildings develop low spots and clogged drains. Standing water breaks down seams and adds load. We clear and reflash drains and recommend drainage corrections where water stands.

FAQ

Roof Repair in Rahway: your questions

Water comes in at the top of the wall on our downtown building. Is that the roof?

Often it is the parapet. Cracked coping or open joints let water into the wall above the roof flashing, and it shows up inside at the top of the wall. We inspect the parapet and the roof together and repair whichever is letting water in.

Our back kitchen roof leaks every winter. Why?

Low-slope rear roofs on older Rahway homes are often covered with material meant for steeper pitches, and snow melt backs up under it. Replacing that section with membrane and proper wall flashing is the lasting fix.

Do you repair roofs on industrial buildings?

Yes. We repair single-ply and built-up roofs on warehouse, industrial and commercial buildings, including seams, drains, scuppers, edge metal and rooftop equipment curbs, and provide photos and a written scope.

Does river flooding damage roofs?

Not directly. Flooding affects basements and lower levels. Where it matters to us is the chimney base, which can deteriorate after repeated saturation. If your basement has flooded, mention it when we inspect the chimney.
