Emergency roof tarping

What to do in the first hour

In this order. The interior is usually the larger loss and the part you can actually affect.

• Move what is under the leak. Furniture, electronics, documents, anything absorbent.
• Contain the water. Buckets, and towels around them to stop splash spreading.
• Relieve a bulging ceiling. A small hole at the low point drains it into a bucket in a controlled way. A collapsing ceiling is a far bigger repair, and a hazard.
• Kill power to affected circuits if water is near fittings or outlets.
• Photograph everything, dated. Before you clean up, and from the ground outside.
• Call a roofing professional. Same-day tarping is a standard call-out in most markets.
• Do not climb up. Not to look, not to place a tarp, not in the rain.

What a proper tarp actually involves

The difference between a tarp that holds for weeks and one that fails in the next storm is entirely in the fixing.

• It extends over the ridge where possible, so water cannot run under the upper edge.
• The edges are secured to the roof, usually battened, rather than weighted down.
• It is taut. A tarp that ponds water adds weight and drives moisture into the deck.
• Fixings are placed deliberately, because every one is a new hole that must be dealt with during the real repair.
• It covers the whole affected area, not just the visible entry point, because water tracks along the deck.
• The attic is checked, so you know whether water is still arriving after the tarp goes on.

What happens on the call-out

1. 01

   Make safe

   The crew assesses whether the roof can be walked at all. A steep or storm-damaged roof in poor weather may mean interior containment only until conditions allow.

2. 02

   Locate the entry

   Not necessarily where the stain is. Water runs along the underside of decking before it drops.

3. 03

   Fit the tarp

   Over the ridge where possible, battened at the edges, taut, covering the whole affected area.

4. 04

   Check inside

   Attic and ceiling, to confirm water has actually stopped arriving.

5. 05

   Document

   Photographs of the damage and of the tarp in place. You will want both for a claim and for the permanent repair quote.

6. 06

   Set the deadline

   A tarp is a holding position with an expiry. Agree when the assessment and the real work happen.

What moves the price

Tarping is a call-out, priced on urgency and difficulty rather than by the square.

We publish no price range for emergency tarping. It is the roofing work where quoted prices vary most, because urgency, weather and local capacity all move it at once.

What to ask before you sign

• Can you get here today, and what is the call-out charge?
• Will the tarp go over the ridge, and how will the edges be secured?
• Will you check the attic to confirm water has stopped?
• Will you photograph the damage before you cover it?
• How long should this tarp hold?
• What is the cost of the tarp against the permanent repair, and does any of it credit across?
• Are you quoting on the permanent work, and am I under any obligation if you tarp it?

The full ten-point checklist is on choosing a roofer.

What to have ready

• Dated photographs of the interior damage before you clean up.
• Photographs of each elevation from the ground, if it is safe to be outside.
• The date and rough time the leak started, and what the weather was doing.
• Your policy declarations page, for when the claim conversation starts.
• Receipts for anything you buy to contain the water.

Where this goes wrong

Common questions

How long does a roof tarp last?

Properly fitted and battened, typically a few weeks to a couple of months depending on weather and exposure. A tarp thrown over and weighted can fail in the first windy night. Treat any tarp as a holding position with an expiry rather than a season-long fix.

Does insurance cover emergency tarping?

Most policies cover reasonable steps taken to prevent further damage, which is usually what tarping is. Keep the receipt and photograph the damage before it is covered. Whether it is reimbursed, and how it interacts with your deductible, depends on your policy and your insurer.

Can I tarp my own roof?

We would not advise it. A wet or storm-damaged roof is the most dangerous version of a roof, pitch is what makes it dangerous, and a badly fitted tarp can trap water against the deck and make the damage worse. Contain the water inside, and call someone.

Will tarping damage my roof?

Every fixing is a hole, so a tarp does add penetrations that must be dealt with during the permanent repair. On a roof that is already leaking that is a reasonable trade. Ask the crew to place fixings where the permanent work will cover them.

Is a tarp a repair?

No. It is containment. It stops water entering while you arrange an assessment and the actual work. A roofer who describes a tarp as the fix is describing something else.

What if the roofer cannot tarp it today?

Contain the water inside as best you can, keep photographing, and keep calling. After a widespread storm every roofer in the market is doing this at once, and a wait is normal. Interior containment and moving contents are the parts you control.
