We take on shingle roofs in El Monte, from a single valley to a full tear-off. Ask us for a free estimate.
Asphalt shingle remains a common roof covering on houses across El Monte. It installs quickly here, and it adapts to valleys, hips, and dormers without much trouble. That makes a targeted repair possible when only one section of the covering fails.
We repair shingle roofs, we tear them off, and we install replacement coverings. The right approach depends on the shingles and the wood deck, so ask us for a free estimate.
We strip the old covering down to the wood deck, then rebuild the roof in order. We lay the underlayment first, then the flashing, the starter course, the field shingles, and the ridge caps. Each layer protects the material underneath it, so the sequence matters.
With the covering off, we can finally inspect the wood deck underneath the shingles. Rot in the deck is the most common surprise, so we replace those boards and show you the material.
We set new metal in the valleys and along the walls, and new collars on the vent pipes. We rebuild the chimney saddles the same way, because sealant alone will not hold a joint for long.
Shingles shed most of the rain, but wind-driven water still slips past them in a storm. The underlayment is the protective sheet beneath the shingles, and it stops the rest. Once that sheet fails, water soaks into the wood deck underneath the covering.
We lay new underlayment on every tear-off, because the shingle test standards require a specific underlayment. Those same standards also specify the fasteners. The asphalt shingle standards summary from the Asphalt Roofing Manufacturers Association spells out both.
Installing new shingles over the old ones costs less up front, but it hides the deck completely. That approach adds weight to the framing and shortens the life of the new roof. We tear off in most cases, and we explain why before you decide.
Sunlight does most of the damage to asphalt shingles in El Monte. Granules wash away, the edges curl upward, and the mat underneath gradually turns brittle. Those weakened spots leak once the winter rain arrives, usually at a valley or a flashing joint.
Wind lifts loose tabs and drives rain sideways underneath the covering, and overhanging trees trap moisture in the valleys. Foot traffic and old patches open the joints that carry the most water.
We inspect the open field of the roof, but the joints take most of our time.
Box vents, ridge vents, and turbines all pull hot air out of the attic space below. Blocked or missing vents trap that heat under the shingles above. We check the ventilation your roof already has before we cover the deck again.
Cities do not all apply the same fire rules to a roof covering. So we call the building department that covers your address before we price the job. California runs its building standards on a statewide code, Title 24, and the 2025 edition is in force now.
The Building Standards Commission code page shows which editions apply today.
One failed valley on an otherwise sound roof usually calls for a straightforward repair. A roof that sheds granules on every plane needs a complete replacement instead. We walk the roof first and show you what we found before you decide on either one.
We price both options when the roof sits between those two conditions.
A shingle tear-off is loud, and the dust lingers around the property for a few days. We start early and work across the roof in sections. We cover whatever sits below the work area and clear the ground before we leave each day.
Roof size drives most of the cost on any shingle job. We measure it in squares, which is the trade term for a hundred square feet of roof. Stories, pitch, the number of layers already up there, and hidden rot move the price too.
We measure your roof from satellite imagery, so the estimate fits your own roof rather than an average one. Give us the property address and we can start on that measurement.
We repair and replace shingle roofs across El Monte and the communities beside it. Downtown and Mountain View are two of the neighborhoods where we handle the most shingle work. We also cover 91731, 91732, and 91733, areas the Census uses to organize local data.
You can see the rest of our coverage on the service areas page.
Call (626) 323-8814 and tell us the property address and roughly how old the shingles are. The estimate is free, and you receive the full scope and the price in writing. You can also send the details through our contact form whenever it suits you.
Shingle questions here usually come back to tear-off, coverage, and the price of the finished roof. We measure the roof planes in squares rather than working from the floor area. The answers below explain that measurement and what a tear-off adds to the work.
It depends on the shingle, because coverage per bundle differs by product. We count from the measured roof area and the waste at hips and valleys. Floor area is not roof area, so we measure the planes from satellite imagery.
We measure the roof in squares of a hundred square feet, not the floor area. Stories, pitch, existing layers, and hidden rot move the price, and the estimate is free. A steeper roof and a second story both add working hours.
Shingle price depends on the scope of the work, not just the product. Ask whether each quote covers a full tear-off or a layer over the old shingles. Roof size drives most of the cost, and our free estimate puts that scope in writing.
