Roof Repair for Manville homes and buildings

Roof repair in Manville centers on small, older homes that have been added onto over the decades. Dormers added to bungalows and capes create sidewall and valley details that were not always flashed well. Rear additions often have shallow roofs that were shingled anyway. Chimney flashing on the single brick chimney is a regular leak point, as are aging pipe boots.

Some older homes in the area may also have cement-based shingles or siding from the mid-1900s, which should be identified and handled appropriately before they are disturbed. Asset Roofing & Chimney repairs asphalt shingle and flat roofs on homes and on Main Street commercial buildings.

Manville housing

Manville's housing is mostly modest single-family homes on small lots: bungalows, small two-story frame houses and capes from the 1920s through the 1950s, with ranches and other homes filling in later. Many have been expanded with dormers and rear additions, and some have been raised or rebuilt after floods. Main Street and the surrounding blocks have small commercial and mixed-use buildings with flat roofs. Most homes have asphalt shingle roofs and a single brick chimney.

Weather & exposure

Manville is low, flat river-plain land, so humidity is high and flood history shapes the town. Damp air and limited attic ventilation in small older homes lead to condensation and mildew on roof decks. Tree cover is moderate along residential streets. Winters bring ice dams on small homes with limited attic insulation, and summer storms bring heavy rain.

Repair or replace? What we tell Manville homeowners

We trace the leak from inside and check whether it is a true roof leak or condensation, since the fixes are different. Roof leaks on Manville homes are usually repaired with new dormer and wall flashing, valley work, pipe boots or chimney flashing. Shingled low-slope additions are best converted to membrane.

If we see roofing or siding that may contain older cement-based materials, we tell you before any work disturbs it so it can be identified and handled appropriately. On commercial buildings we start with drains and seams and provide a written scope.

Manville Specifics

Roof problems we see in Manville

Added dormers on bungalows and capes

Dormers added after construction create new sidewalls and valleys. Where the flashing was not integrated properly, water enters at the dormer cheeks and front corners.

Shallow rear additions

Small additions with near-flat roofs are common. Shingles on a roof that shallow let water back up in heavy rain and snowmelt.

Condensation in small, damp attics

Low, humid ground and little ventilation lead to moisture on the underside of the deck, which can look like a leak and softens sheathing over time.

Older cement-based roofing and siding

Some mid-century homes still have cement-based shingles or siding. These should be identified before work disturbs them, so the right handling can be planned.

FAQ

Roof Repair in Manville: your questions

Our attic ceiling is wet but the roof looks fine. What is happening?

It may be condensation rather than a leak. Warm, humid air from the house reaches the cold roof deck and condenses. Better ventilation and sealing air leaks from the living space are the usual fixes. We inspect to tell the difference.

Water comes in around our dormer. Can you fix just that?

Yes. We open the siding and shingles at the dormer junctions, install new step flashing and corner flashing, and close it back up with matching material.

We think our house has old cement shingles. Can you still work on it?

We will look and tell you what we see. Older cement-based materials should be identified before they are disturbed, and if testing or special handling is needed, that needs to be arranged before roofing work proceeds.

Do you repair flat roofs on Main Street buildings?

Yes. We repair membrane and built-up roofs on commercial and mixed-use buildings, including seams, drains, scuppers and flashing.
