Call (562) 414-1770Westminster is in west Orange County between Garden Grove and Huntington Beach, about 25 minutes from our Long Beach office by the 405 or the 22. The 405 crosses the city and the 22 runs along its northern edge. Beach Boulevard and Bolsa Avenue are major routes through town.
Many of our Westminster calls come from owners of long-held family homes whose shingles have reached the end, and from small business owners with leaking flat roofs. We give straight answers on repair versus replacement and clear prices for both. Because so many Westminster homes share the same era and layout, we can usually tell from a short walk where a roof is likely to fail next: the valleys over the garage, the pipe boots, and the seam where a back room was added.
Mid-century homes and busy commercial corridors
Westminster homes are mainly one-story stucco ranch and tract houses built in the 1950s and 1960s, with gable and hip roofs. Most have been re-roofed with asphalt shingle, and some with concrete tile. Many homes have room additions and patio covers with low-slope roofs. Original sheathing on some of these homes is spaced board rather than plywood, which matters when a new roof goes on, since modern shingles need a solid deck.
Commercial corridors such as Bolsa Avenue and Brookhurst Street have many small shopping centers and offices with flat roofs, often with rooftop units and signs. Westminster is a few miles inland, so it gets some marine air but mainly deals with sun and age.

Roof problems we see most in Westminster
Shingle wear on older homes
Granule loss, curling and cracked tabs are common on aging Westminster shingle roofs. These roofs often need full replacement.
Additions with poor flashing
Room additions and enclosed patios often join the main roof with weak flashing. Leaks at the wall line show up during heavy rain.
Flat roofs on small centers
Shopping center roofs with many rooftop units have lots of penetrations. Each one is a leak risk if the flashing fails.
Hot attics with poor airflow
Many homes have limited attic vents, which shortens shingle life. Better ventilation helps the next roof last longer.
Westminster permits and scheduling
Westminster has its own building department, and re-roofs require a city permit and inspection. We handle the paperwork and the inspection. If your re-roof falls under Title 24 cool roof rules, we confirm which shingles qualify for your slope.
For commercial jobs, we plan around store hours and tenants. For homes, most single-story shingle re-roofs take two to three days. We keep tarps on our trucks during the rainy season and answer the phone 24/7 for active leaks. Westminster sits about five miles from the ocean, so marine haze rolls in on summer mornings, but salt corrosion is milder here than in Huntington Beach or Seal Beach. Sun and heat drive most of the wear we see.

Questions from Westminster
How long does a shingle re-roof take on a Westminster home?
Most single-story Westminster homes take two to three working days for a full shingle re-roof. Decking repairs or an addition with a separate low-slope roof can add time. We tell you the plan before tear-off starts.
Can you fix a leaking roof on my Westminster shop without closing?
Usually yes. Most commercial roof repairs in Westminster are done from the roof with no work inside. We coordinate access and any rooftop unit shutdowns with you in advance.
What shingles hold up best on Westminster homes?
Architectural asphalt shingles are a good fit for most Westminster homes and hold up well to sun. Some lines offer cool-rated colors that reflect more heat. We help you choose based on look, budget and any cool roof requirement.
