Roof Replacement in Longview, WA

Most Longview houses are on their second or third roof by now. Census data shows 28% of the city’s homes were built before 1950 and another 46% between 1950 and 1979, so the shingles you see today often sit on decking, vents and flashing left from an earlier job. As a roofing contractor in Longview, Builders Service Company handles roof replacement and new roof installation with asphalt shingles or EDCO metal, and every project starts by finding out what the old roofs left behind.

Roofs on Longview homes

Longview grew as a planned city, and much of its housing went up between the 1920s and the 1950s. Census data counts 16,826 housing units here, with a median build year of 1967. That mix gives roofs in town a wide spread of ages and histories.

• Built before 1950: These homes have been reroofed several times. We look for stacked layers, board decking that has dried and split, and chimney or wall flashing that has been patched rather than replaced.
• Built 1950 to 1979: The largest group. The rafters and decking are usually sound, but vents and flashing from past reroofs often no longer match the current roof.
• Built 1980 and later: About 18% of homes date from 1980 to 1999 and 8% from 2000 on. Many of these are due for their first full tear-off, which is the best chance to correct ventilation and underlayment the builder skimped on.

Detached single-family houses make up 60% of Longview’s housing and attached homes another 11%, and those two groups are where most of our residential roofing work happens. With 55% of homes owner-occupied, many owners here are planning a roof they will live under for a long time.

Longview’s weather and your roof

Longview sits in Washington’s Southwest interior, a region defined by wet winters and river flooding. Months of steady moisture are the main wear on a roof here. A roof that stays damp from fall into spring grows moss, holds water at its edges and finds every weak spot in the flashing. These details do the most good on a Longview reroof:

1. Full underlayment on a sound deck. We replace soft or rotted decking before anything goes down, then cover the whole deck so a lifted shingle or a wind-driven rain does not reach the wood.
2. Balanced attic ventilation. Intake at the eaves and exhaust near the ridge move damp air out of the attic, so it does not condense on the underside of the deck through a long wet season.
3. New flashing at every transition. Walls, valleys, chimneys and pipe vents get new metal rather than reused pieces from an older roof.
4. Drip edge and gutters that work together. In a region that already deals with river flooding, roof water should leave the eaves cleanly and be carried away from the house, not spilled against the siding and foundation.

Fire is a smaller factor. Longview’s wildfire risk is rated Low, at the 36th percentile for Washington, so the material choice here comes down to how each option handles rain over many winters rather than to fire rating.

Asphalt shingle or metal in Longview

Both roofs we install hold up to a wet climate when the details underneath are right, and we give them equal weight.

Asphalt shingles suit the pitched roofs found on most older Longview houses. They come in a wide range of colors, keep a traditional look that fits homes from the 1920s through the 1970s, and a damaged section can be repaired without disturbing the rest of the roof.

EDCO metal roofing comes in long panels with fewer seams for water to work into, and rain runs off it quickly. Moss has a harder time getting established on a smooth metal surface than on textured shingles. Unlike old cedar shakes, neither option rots when it stays wet.

The median home value in Longview is about $360,000, 3% above the Cowlitz County median, and both roofs make sense at that level. The choice usually turns on how long you plan to stay, the shape of the roof and the look you want. We bring samples of both to the consultation and talk through them on your house, not in the abstract.

Signs your roof needs replacing

In Longview, the warning signs usually trace back to moisture:

• Moss pushing up shingle edges. Once moss lifts the tabs, rain gets under them, and cleaning alone will not reseal them.
• Stains on the attic sheathing after a rainy stretch, or a musty smell up there in winter.
• Soft spots or sagging between rafters, a sign the decking has been wet for a while.
• Rot along the eaves and fascia, where water runs off a roof edge with no working drip edge.
• Repeated patches at the chimney or walls. If the same flashing leaks every winter, the roof around it is often near the end too.
