Signal Hill has no neighbors to hide behind. It is a 365-foot rise completely surrounded by Long Beach, and a house near the top takes wind from every quarter with nothing upwind to slow it down. That is why covers fail here at the perimeter rather than over the damage. An oversized sheet flaps, the flapping works fasteners loose, and by the second night the whole thing is in somebody's street. We size covers to the opening, bury the edges under the course above, and fasten into framing rather than into sheathing.
The building mix is unusual as well. The 1921 Alamitos No. 1 strike set off one of the most productive oil booms in American history and the field still produces, so active wells and oilfield infrastructure sit intermixed with housing. Much of the newer hillside stock went up on former oil land, on steep engineered lots with retaining walls and terrace drains, where storm water arrives with velocity instead of ponding. Add a strong marine influence and you have damp materials in a high-wind location, which is demanding for anything temporary.
What Signal Hill Changes About Board-Up & Tarping
1Hilltop lots take wind from every side
On most jobs you can identify a windward plane and detail it harder. Up here the exposure changes with the system, so every edge gets the same treatment: sized to the opening, lapped under the course above, fastened at close spacing all the way around. Anything left free to lift will lift, and on this hill a loose corner becomes a fully detached cover within a night or two.
2Steep driveways limit truck placement
Lots here are stacked and cut into grade, with short steep driveways and retaining walls right at the property line. A loaded truck often cannot get above the house, so material is carried up and staged on a terrace. Plan on a longer setup than the same job would take on flat ground in Carson or Paramount, and on a crew working the roof from the uphill side.
3Working around active well sites
Housing on this hill shares the neighborhood with operating oilfield equipment and its access lanes. We keep trucks, ladders and material clear of those lanes and gates, since operators need to reach a site at any hour and a blocked access road is a real problem rather than an inconvenience. Where a property line runs against oilfield land, we confirm the boundary before setting anything up outside the fence.
How the Work Runs
The method is the same one we use on every board-up & tarping job, documented to the IICRC S500:2025 standard. Here it is in short — the full emergency board-up & roof tarping process explains each stage in detail.
- Safety and structure first
- Photograph the opening before we cover it
- Dry-in the roof opening
- Board and brace the openings
- Shore what is carrying load
- Handle the water already inside
The Signal Hill Background Worth Knowing
On these lots the drainage is engineered rather than natural. Terrace drains catch water partway down a slope, v-ditches carry it around a pad instead of across it, and retaining walls have weep holes with a gravel drain behind them so pressure never builds in the soil. All of that works until something clogs. Then a retaining wall stops being a wall and starts being a dam, and saturated soil pushes water through the joints and into whatever sits on the other side, which is usually a garage, a storage room, or the back of a lower level.

What It Costs in Signal Hill
We do not quote a number over the phone before seeing the property — anyone who does is guessing. The variables that actually move the price on a board-up & tarping job are area covered and roof pitch, number and size of openings, conditions at the time of the call, and they are broken down in full on the emergency board-up & roof tarping page. The assessment and the written estimate are free anywhere in Signal Hill, day or night, with no obligation.
Board-Up & Tarping Questions from Signal Hill Homeowners
Look at how it was attached. Nearly every failed cover we replace on this hill was an oversized sheet held down with rope, sandbags or staples, with free edges left flapping. We cut to the opening, screw furring strips through the material into rafters, and run the top edge up under the course above so wind cannot get a lip anywhere along the perimeter. With marine damp working against fasteners here, we use coated screws and check the install after the next blow.
A properly fastened tarp on a sound deck holds for weeks and gets you through the rest of a wet season. We have had covers stay tight for a couple of months while claims and permits worked out. That said, it is temporary by design — the material degrades in UV, and every storm works on the edges. If yours is going to be up longer than a few weeks, we come back and check it rather than assuming.
Usually not. Most policies require you to take reasonable steps to prevent further damage and allow emergency mitigation without waiting for an adjuster — waiting is often the thing that creates a coverage argument. Call your carrier and open the claim, then let us secure the building. We photograph everything before and after and give you an itemized invoice, which is what the adjuster needs to approve the emergency line separately from the repair scope.
Start uphill. On this hill the cause is almost never at the place the water got in. Walk the slope above your pad and check the terrace drains, the v-ditch and the retaining wall weep holes. A weep that has been painted or stuccoed over is common and completely disables the drain behind the wall. Then look at where the uphill property discharges. Fixing the entry point without finding the redirect just moves the problem a few feet.
