6,000 Sq. Ft. Cool Roof Replacement In Encino, CA

A cool roof replacement in Encino means a new roof built to reflect more of the sun's heat. The City of Los Angeles requires one on most re-roofs. On this hillside home we replaced about 6,000 square feet of roof with Owens Corning Duration COOL Plus shingles in Mystic Gray. It's a medium gray that still meets the city's rule.

The house sits under oak trees, with a pool out back. Its long, low roof wraps around the house in hips and valleys, so there was a lot of roof to get right.

What Is A Cool Roof?

A cool roof is one built to reflect more of the sun's heat instead of soaking it up. On a shingle roof, that comes from special granules on the shingle surface that bounce back more sunlight than regular granules do.

Every cool roof product gets a score called SRI, short for Solar Reflectance Index. A higher SRI means the roof stays cooler in the sun. An independent group, the Cool Roof Rating Council, tests and lists these products, so the score on the label is the one inspectors check.

On a roof this size, that matters. Thousands of square feet of shingles facing the Valley sun is a lot of surface sitting above the attic all summer. Owens Corning says its cool roof shingles may help lower household energy use by keeping the roof cooler.

Does A New Roof In Encino Have To Be A Cool Roof?

For most re-roofs, yes. Encino is part of the City of Los Angeles, which requires cool roofs on new and replaced roofs. For a sloped roof like this one, LA's cool roof rule sets a minimum score of 20. Owens Corning says its COOL Plus colors meet or exceed that minimum. The same brochure says these cool roof shingles meet the cool roof requirements of Title 24, California's energy code.

Re-roofs in Encino are permitted through LADBS, the city's building department, and the shingles have to be a rated cool roof product to pass. Rules can change, so check with LADBS or ask us during your estimate. We handle the permit and the inspections on every re-roof.

Why Mystic Gray?

A lot of homeowners hear "cool roof" and picture a white roof. You don't have to go white on a sloped roof in LA. Mystic Gray is a medium gray with a slight green undertone. On this house it sits quietly against the oaks and the hillside, and it still scores above the city's minimum.

Here's how Mystic Gray compares with other Owens Corning cool colors:

Higher is cooler. Scores from the Owens Corning Duration COOL Plus brochure; LA minimum from the Cool Roof Rating Council.

Mystic Gray is listed with the Cool Roof Rating Council under product ID 0890-0032, so its rating can be checked independently. We used the brightest option on our Northridge cool roof, Shasta White. This Encino job shows the other end of the choice: a mid-tone gray that passes without looking like a cool roof at all.

What We Found Under The Old Roof

With the old roof off, the deck turned out to be wood boards rather than plywood. Older homes were often built this way, with long planks nailed side by side across the rafters. A board deck can hold a new roof well, but only after it's checked board by board.

Some boards were damaged, so we cut those out and set new wood in their place before anything new went on. A shingle roof is only as solid as the wood under it. A soft board shows up later as a dip or a loose shingle.

What Goes Under The Shingles On A Cool Roof Replacement In Encino

A cool roof is only the top layer. What keeps a roof dry for decades is everything under it, and on a roof with this many hips and valleys, the details add up.

• Synthetic underlayment over the whole deck (Titanium UDL50). This is the white sheet with the purple print in the photos. It's Owens Corning's heavy-duty synthetic underlayment, lighter and tougher than old-style felt paper, so it holds up while the crew works across it for days.
• Metal in every valley. Valleys carry the water from two slopes at once, so they're the first place an old roof leaks. We lined each one with metal before the shingles went on.
• New flashing at the chimney. The chimney chase got new metal flashing where it meets the roof, which is one of the most common leak points on any house.
• New vents. Box vents and round attic vents went back in with new flashing, so the attic can breathe and every opening is sealed.
• Hip and ridge caps. Every peak and hip is finished with matching cap shingles, which close the top of the roof and give it a clean line.

How A 6,000 Sq. Ft. Roof Comes Together

A roof this large isn't done in one push. We worked it in sections: strip an area, repair the deck, seal it in underlayment the same day, then come back with shingles. In the photos you can see one section already shingled while the next is still in underlayment, with bundles staged on the roof.

That approach keeps the house protected the whole way through. It also means the crew is never racing to cover a huge open area before the end of the day. On a hillside lot with a pool below, debris control matters too. Materials stay staged on the roof, and each section is cleaned up as it finishes.

What Warranty Comes With Owens Corning Cool Roof Shingles?

Owens Corning lists a limited lifetime warranty on Duration COOL Plus shingles, which it defines as for as long as you own your home. As an Owens Corning Preferred Contractor, we can also offer upgraded Owens Corning warranty coverage on eligible systems. A warranty is included with every re-roof we do, and the exact terms for your roof are spelled out in your estimate.

Encino Homes And New Roofs

A lot of Encino's housing is now old enough for its second or third roof. Census data puts the median year built for homes in Encino's ZIP codes at 1967, and about three in four were built before 1980 (U.S. Census Bureau, ACS 2020–2024). Many of those homes are large, spread-out ranch and hillside houses like this one, where the roof is a big part of what you see.

If you'd rather go darker, our Encino shingle roof replacement used Midnight, one of the darkest colors that still meets LA's cool roof rule.
