Why El Monte Chooses El Monte Roof Pros
- ✓Every estimate states the layer count, the deck type and a per-sheet plywood price, so the number after tear-off is the number you were quoted
- ✓We measure rafter dimension, spacing and span from the attic before quoting any covering heavier than composition
- ✓Ventilation is sized by published net free area against attic floor area, not by counting vents on the roof
- ✓Counterflashing is cut into a fresh reglet at the correct height for the finished roof rather than re-sealed at the old one
- ✓Synthetic underlayment goes down the same day we strip, and no deck is left open overnight against a forecast
- ✓We quote the cheaper repair or recover alongside the replacement whenever your roof actually qualifies for one
How It Works
We Count the Layers First
We lift a shingle at the eave, at a valley and at the ridge, and count the coverings. Two layers of composition over spaced 1x6 boards prices nothing like one layer over half-inch plywood, and no honest number exists until somebody has looked. You get photographs of the exposed edge.
Deck and Load Measured, Not Assumed
From the attic we record rafter dimension, spacing and span, the deck type, daylight at the joints, and any staining on the rafter tails. That is what tells us whether the covering you want is a permit or a structural letter, and it takes one visit rather than a change order.
A Written Estimate With the Deck Priced
Plywood by the sheet, tear-off tonnage, dump fees, ventilation, drip edge, valley metal and flashing, all named as separate lines. If we think a recover or a repair is the better spend on your roof, that version is on the same page next to the replacement.
Strip, Repair the Deck, Dry In the Same Day
We tear off, replace the sheathing that will not hold a fastener, reset vents and curbs to the new roof plane, and get synthetic underlayment down before the crew leaves. Nothing sits open overnight against a forecast, and every penetration gets flashed to bare deck.
Our Roofing Services in El Monte, CA
Roof Replacement & Full Tear-Off
A replacement quote here is really two numbers, and only one of them is about roofing. The first covers the covering and the labor to install it.
Roof Leak Repair
Water on a layered roof does not travel in a straight line. It gets under the top covering and runs sideways along the old field beneath it.
Storm Damage Repair & Restoration
Storms here arrive as a week of wind-driven rain rather than as a single violent event, and that pattern finds one very specific weakness. Layered roofs fail at the fasteners, because the nail that was right for one covering is short for two.
Hail Damage Inspection & Repair
Hail is not the common failure mode in this valley. The most useful thing an honest inspector does here is tell homeowners when what they are looking at is not hail.
Wind Damage Repair
Santa Ana winds come down out of the passes dry and hard, and they get under roofs at the edges. On a roof carrying two coverings the edge is exactly where the extra layer has left a lip for the wind to grab.
Roof Inspections & Layer Assessment
An inspection that does not tell you how many coverings are on the roof has not told you the thing that matters most. Layer count sets the cost of every future decision on that house, and establishing it takes about ten minutes.
Asphalt Shingle Roofing
Homeowners spend weeks choosing a shingle and about four minutes on the deck it fastens to, which is backwards. On this housing stock the deck decides how long the shingle lasts, and the deck is invisible until the old roofing is gone.
Metal Roofing & Standing Seam
The reason to look at metal on a San Gabriel Valley tract house is weight, not appearance. Steel panel runs around a pound and a half per square foot against nine and a half to eleven for concrete tile, and on 2x4 rafters that difference is the whole argument.
Tile Roofing
Wanting tile on a house that was built with composition is a structural question before it is an aesthetic one. Concrete tile lands between nine and a half and eleven pounds per square foot.
Flat & Low-Slope Roofing
Almost every low-slope surface on these houses is younger than the house. Carports, patio covers, porch returns, and rear additions arrived over decades.
Roof Coatings & Sealing
This is the page where we argue against the product more often than for it. A coating over two layers of composition shingle is money spent on a roof you are still going to tear off, and it does not make the tear-off cheaper.
Roof & Attic Ventilation
Recovers bury ventilation. Every time a covering goes on over an existing field the roof plane rises an inch or more, and vents flashed to the original plane end up sitting low, half-buried, or choked at the throat.
Skylights & Sun Tunnels
Skylights on recovered roofs leak for a reason that has nothing to do with the skylight. The curb was flashed to the original roof plane.
Gutters & Downspouts
Every added covering raises the shingle edge and the gutter stays where it was. Gain an inch or two of rise and water leaving the roof arcs over the front lip.
Fascia & Soffit Repair
The eave is where a layered roof's mistakes collect. Every covering added over the last one pushes the field further past the fascia, and without a drip edge sized for the new height, water runs down the back of the board instead of off the front of it.
Chimney & Wall Flashing
Counterflashing is cut into masonry at a fixed height. Add a covering to the roof and that height shrinks, because the field rose and the reglet did not.
Emergency Tarping & Dry-In
A tarp on a layered roof cannot be nailed the way a tarp on bare deck can. Battens screwed through three coverings hit asphalt rather than wood, pull out in the first gust, and leave fastener holes in a roof that was already leaking.
Commercial Roofing
Layer limits apply to a warehouse as much as to a bungalow. The stack on a light-industrial building in this valley is usually deeper.
Insurance Claim Support
A policy pays for a sudden event. It does not pay for a roof that wore out.
What El Monte Customers Say
Three companies quoted a replacement off a photo. These guys lifted shingles at the eave and the ridge, found we were already on two layers, and gave us a per-sheet plywood price up front. Final invoice matched the estimate to the dollar.
We had a stain at a hallway light and assumed the roof was finished. They traced it uphill to a valley where the old metal had been left in and the new field cut short, rebuilt the valley, and told us the roof had another eight years. Nobody tried to sell us a reroof.
Asked for a coating on the carport and the shingle roof above it. They coated the carport and refused to coat the shingles, then explained exactly why. First contractor who has ever talked me out of spending money.
Tile roof, leak at a chimney every winter. They found the counterflashing sitting too low because the roof had been recovered, cut a fresh reglet at the right height, and added a cricket. Two wet seasons since and the shaft is dry.
El Monte Roof Pros is a licensed, insured roofing contractor handling roof replacement, roof leak repair, tile, metal and low-slope work across El Monte and the wider San Gabriel Valley. Our estimates start from what is already on the deck, because one layer of composition, two layers, or a shake-and-tile stack are three different jobs at three different prices.
We install architectural laminate shingle, UL 2218 Class 4 impact shingle, concrete and clay tile, lightweight tile, stone-coated steel, twenty-four gauge standing seam panel, and sixty-mil TPO or two-ply SBS modified bitumen on the flat sections. Residential and commercial both, from a post-war tract house with 2x4 rafters to a distribution roof with forty penetrations and a drain that has never been surveyed.
The California Residential Code stops at two roof coverings, so a third is always a full tear-off. A tear-off is also the only moment a rotted 1x6 skip-sheathed deck, a cracked rafter, or a vent buried by the last recover becomes visible. So we price plywood by the sheet in writing before we start, dry in with synthetic underlayment the same day we strip, and back the work with a written workmanship warranty.
About El Monte Roof Pros in El Monte, CA
El Monte Roof Pros is a roofing contractor working El Monte and the surrounding San Gabriel Valley, from single-family tract housing on 2x4 framing to light-industrial low-slope roofs. Most of what we do is decided by what is already on the deck, so most of what we sell is an accurate count and an accurate number rather than a product.
That shapes how we quote. Layer count, deck type, rafter size and span, ventilation net free area and counterflashing height all get recorded before a price is written, and plywood is priced by the sheet up front instead of appearing as a change order on day two. We would rather lose a bid on an honest deck allowance than win one and renegotiate it on the roof.
There are jobs we tell people not to give us. If your roof is on one sound layer with ten years left in it, we will quote the flashing repair rather than sell a replacement. If you want a coating over a doubled composition roof, we will decline the work and explain why. And if the covering you want needs framing we are not licensed to alter, we say so and bring in an engineer.

Commercial Roofing in El Monte and Across the San Gabriel Valley
The industrial belt through El Monte and its neighbours is full of nineteen-sixties and seventies tilt-up and masonry buildings, and their roofs carry deeper stacks than any house. Three or four plies of built-up work, a later cap sheet, and two decades of undocumented patching is the normal finding. We core before we quote, so the recommendation names plies, insulation type and whether that insulation is dry.
- ✓Two-inch core samples on a grid, logged on a roof plan before any price is written
- ✓Sixty and eighty mil TPO, mechanically attached or induction-welded, with probe-tested seams
- ✓EPDM where foot traffic and kitchen grease exposure rule out a welded thermoplastic
- ✓Two-ply SBS modified bitumen for small cut-up roofs and older masonry parapet detailing
- ✓Tapered insulation and corrected slope at drains during tear-off, not after
- ✓Fastener pull tests on the actual steel deck to set the attachment pattern
- ✓Twice-yearly inspections with a drain, seam and penetration log per building
- ✓Capital planning by roof section for multi-tenant industrial and retail owners
Frequently Asked Questions
How many layers of roofing can a house in El Monte have?
Two. The California Residential Code allows one recover over an existing covering and no more, so a third job is always a full tear-off. That is worth knowing before you buy, because it is the single biggest swing in what your next roof costs. We count the layers on the first visit and photograph the exposed edge so the count is documented rather than asserted.
My house has tile over an old shake roof. Is that a problem?
It is common here and it is worth taking seriously. Shake left in place means the tile is bearing on spaced 1x6 boards rather than a solid deck, and the combined dead load is well past what 2x4 rafters at twenty-four inches were drawn for. It usually still stands up. It also means your next roof is a full strip to bare framing, so budget for re-decking.
Why did my last roofer's price jump once the tear-off started?
Because the bid priced the covering and not the deck. Rotten sheathing, a cracked rafter tail, a buried vent and an undersized counterflashing reglet are all invisible until the old roofing is off, and a bid written from the driveway has no allowance for them. Ask for a per-sheet plywood price and a stated deck allowance in writing before anyone starts.
Do I have to re-deck if I go from tile to composition shingle?
Almost always, yes. Tile and shake originals were laid on spaced boards, and a shingle over spaced boards has unsupported span between the gaps, telegraphs the lines, and cannot hold a nail that lands in air. Solid half-inch CDX or seven-sixteenths OSB goes down first. It is a real line item, not an upsell, and it is also the moment ventilation can be corrected.
Is a recover over one existing layer ever the right call?
Yes, and we quote it when it is. One sound, flat, correctly nailed layer on a solid dry deck can take a recover, which skips the removal and saves real money. What rules it out is soft sheathing, a second existing layer, a cupped field that new shingles will telegraph, or a sale inside two years where a doubled roof becomes a negotiation.
Will a reroof trigger California energy requirements?
It can, and the answer belongs to plan check rather than to a salesman. El Monte sits in California Energy Commission climate zone 9, and reroof work is reviewed against the current Energy Code, which offers a prescriptive path with reflectance and emittance minimums and a performance alternative. How much of the roof you touch matters. Get the determination in writing before the tear-off.
