Feature by feature, from the solar array and the ridge down to the dryer vent, with the order of operations that makes it hold.

Or Call Us NowQuick answer. Bird proof a house feature by feature in one pass rather than by buying a single product: rigid galvanized mesh around the full solar array perimeter, spikes covering the full depth of ledges and beams, tensioned netting across open patio and porte cochere spans, and purpose made guards on dryer, wall and roof vents. Nests and droppings come out and the area gets sanitized before anything is closed up, otherwise you have sealed a contaminated space behind a barrier. Do it piecemeal and the flock simply relocates ten feet down the roofline. Valley Wash Pros is based in Fresno and works across the Central Valley, but that order of operations holds on any roof.
Bird proofing a home means going feature by feature and closing every sheltered ledge and opening a bird can use, in one pass. Solar array perimeter gets rigid mesh, ledges and beams get spikes in enough rows, open spans get tensioned netting, and vents get purpose-made guards. Nests and droppings come out and the area gets sanitized before anything is closed up. Do it piecemeal and the flock just relocates ten feet.
The first job is walking the whole roofline and writing down every place a bird lands, shelters or enters, because a single missed opening undoes everything else.
Birds are opportunists with a lot of free time. Close the array and leave the patio cover open and the colony moves to the patio cover, so you paid for half a solution and still have the noise. That is the most common way bird proofing money gets wasted.
So the sequence is: map every location, decide the barrier for each one, remove and clean, then install. On homes with multiple roof planes, hillside exposure and detail work that cannot be seen from the ground, the map is most of the value. Half the entry points are invisible from anywhere you can stand.
Order of operations matters as much as the map. Nests, eggs and packed material come out first and get bagged on the roof rather than pushed into the yard. Then everything affected gets cleaned and sanitized. Then the barriers go on, over clean surfaces.
The gap between the panels and the roof deck is the single best nesting site on almost any house, and it needs rigid galvanized mesh around the full perimeter.
Not just the front edge. The front edge is the one you can see from the driveway, which is why it is the one cheap installs cover, and birds simply walk in from the sides and the back instead. The mesh is cut to the actual gap, including where the roof plane changes and the rail height changes with it, and the corners and rail terminations are worked last. A pigeon walks through a two inch opening without slowing down.
It clips to the panel frame with purpose-made fasteners. Nothing gets drilled through your panels, your racking or your roof covering. Ask any bidder to say plainly how they attach it.
Clay and concrete tile give birds two things at once: a ridge to stand on, and open ends where the tile meets the ridge and the rake.
Ridge and hip lines take spikes, set in enough rows to cover the full depth. One row on a wide ridge cap just gives the bird a narrower place to stand. Open tile ends and eave closures need proper closure material rather than expanding foam, which cracks, discolors and lets water sit.
A tile roof also has to be walked correctly. Tile is only strong where it is supported, so you walk the lower third of each tile, over the batten and the head of the tile below it, with weight straight down instead of dragged sideways. Step in the middle of the span and the crack shows up as a ceiling stain the next time it rains hard. On a long run we set the walk path before anyone climbs, because nobody should be improvising footing while carrying a ten foot roll of mesh.
An open eave with exposed rafter tails is a row of sheltered ledges, and each bay is a nesting site.
The fix is closure, not deterrence. Small-gauge mesh or purpose-made bay closures, cut and fitted to each bay. Where the eave is architectural and cannot be closed visually, netting stretched along the run on an edge cable does it, and it disappears at a distance when tensioned properly. Check soffit vents and the soffit to wall joint on the same visit. A gap you can fit two fingers into is a door.
Any vertical opening on the roof is a nesting cavity waiting to be found, and every one of them should have a proper cap or guard.
Chimney caps, flue guards and vent screens are inexpensive and they solve a category of problem that gets expensive fast. A nest inside a flue is a blockage as well as a fire concern, and a bird that gets into an attic through an unguarded vent turns a roof problem into an indoor one, mites included.
Exterior dryer vents are one of the most commonly overlooked nesting spots on a house, and a guard takes minutes.
The flap opens, the duct is warm and dry, and it is completely hidden. Birds find these constantly. The right fix is a purpose-made guard that still lets the flap operate and lets lint out, not a piece of screen taped over the hood, which turns into a lint fire hazard. Same idea for bath fan terminations and range hood exhausts.
Open covered spans are netting country. Nothing else closes a volume.
The failure mode is tension. Slack netting sags into a hammock and birds sit in it, which is worse than no netting because now they are roosting on hardware you paid for. Edge cable, correct anchors, correct tension, and every corner closed. A bird will find the one edge nobody tied off. Beams, rafters and column tops inside those structures usually take spikes at the same time, since closing the span without addressing the landing surfaces just moves birds around inside it.
Flat horizontal surfaces at height are landing zones, and spikes are the right tool as long as they cover the full depth.
Ledge depth decides row count. Window heads, cornices, sconce tops, parapet caps, the flat top of a gate post. Spikes here are cheap, permanent and low maintenance, with one caveat: under trees they collect leaves until the strip itself becomes a nest platform. Plan on clearing them occasionally.
Some of the pressure on your roof comes from the yard, and a little pruning does more than another product.
Untrimmed palm skirts are excellent nesting habitat sitting directly beside the roof. Dense ivy does the same lower down. Overhanging limbs give birds a staging perch with a clean approach to the roof. Also check pool equipment enclosures, side yard alcoves and anything with a roof and one open side, because those get missed.
Skip anything that works by trying to convince a bird that a good spot is a bad spot.
Decoy owls stop working within days and often become perches. Reflective tape and spinners startle briefly, then shred in the wind and end up in the gutter and the pool. Ultrasonic units do essentially nothing, because birds hear in roughly the same range people do and habituate quickly to anything harmless.
Also skip expanding foam as a closure material, skip screen taped over a dryer vent, and skip sealing anything up before the nest and droppings are removed. All three create a second problem to pay for later.
Two things move the price and neither can be judged from the ground, which is why a number given over the phone is a guess.
The first is linear feet of open perimeter and open span, because barrier products are installed by the foot. Sixteen panels in two tight rows have far less open edge than sixteen panels in one long run. The second is how long the birds have been there. A nest from this spring is a bag of material. Three seasons of a colony is a cleanup and sanitizing project before the exclusion work starts.
A real scope tells you which barrier goes where, what gets cleaned and sanitized, whether the gutters get flushed, and what the roofline looks like when the crew drives away. If there are eggs or young in a nest right now, that changes the schedule, so ask before you book.
