TL;DR
- Call for emergency tarping if water is actively coming through your ceiling or a tree fell on the roof — non-emergency damage can wait for a scheduled repair
- Commercial tarps last 4-8+ weeks; hardware-store blue tarps fail in 24-72 hours due to thin material and no proper fastening
- Emergency tarp costs range from $150 (small section) to $1,800 (full roof), and all tarp costs are credited toward the permanent repair
- Emergency tarping is almost always covered by homeowner insurance as required mitigation — save the invoice for your claim
Water coming through a ceiling in the middle of a winter storm is about as stressful as homeownership gets. Here’s what to do, when to call, and what to expect.
What counts as a roofing emergency
Call for emergency response immediately if:
- Active water coming through a ceiling during or right after rain
- Tree or large limb fell on the roof with visible damage or active leak
- Wind event lifted or tore off visible sections of roofing material
- Broken skylight glass exposed to weather
- Hail damage with active leak (rare in SD but happens)
- Structural concern — visible sagging or damage that looks unsafe
It’s NOT an emergency (and can wait for a scheduled repair) if:
- Small ceiling stain from a leak that stopped when the rain did
- Missing shingles or tiles visible from the ground but no active water intrusion
- Damage you discovered but there’s no rain forecast
- Gutter overflow or exterior damage without roof penetration
Emergency response carries a $249 after-hours dispatch fee. Non-emergency repairs skip that and get scheduled same-week at regular rates through our roof repair service.
What should you do before we arrive?
If you have an active leak, do this immediately:
1. Move what you can move
- Electronics, paper, fabric furniture away from the leak path
- Boxes or storage that will absorb and hold water
- Anything valuable out of the affected area
2. Catch the water
- Put a bucket (or multiple) under active drips
- Line the bucket with a towel to reduce splashing
- Replace buckets before they overflow — set a 30-minute reminder
3. Shut off relevant circuits
If water is reaching:
- A light fixture: shut off that circuit at the breaker panel
- Electrical outlets: shut off that circuit
- Smoke detectors that look wet: shut off the circuit
Water + live electricity = bigger problem than a leaking roof. Shut it off, make the call, wait for us. If you’re unsure which breakers control the affected area, or if you notice any sparking or burning smell, Bright Pro Electric can send someone to assess the electrical side while we handle the roof.
4. Document with photos
- Before we arrive: photograph the interior damage, wet areas, any belongings affected
- Time-stamp matters: newer phones include this in metadata automatically
- This helps with insurance claims later
5. Call us
(858) 400-8901 — the number is answered 24/7. Tell us:
- Your address
- Nature of the damage (active leak, tree down, wind damage, etc.)
- Whether there’s active water coming in right now
- Whether the damage is accessible (single-story vs. two-story, steep roof, etc.)
We give you an honest ETA. Typical response times:
- Central San Diego, Chula Vista, La Mesa: 60–90 minutes
- Coastal north county (Carlsbad, Encinitas, Del Mar): 75–120 minutes
- East County (El Cajon, Santee, inland): 75–120 minutes
- Mountain communities (Julian, Alpine, Pine Valley): 90–180 minutes
What to expect when we arrive
- Safety assessment first. We look at whether the roof is safe to climb (wet, steep, damaged structure).
- Damage documentation. Photos, moisture readings, scope assessment.
- Tarp install over the damaged area.
- Interior water mitigation coordination — we refer water-damage specialists if needed.
- Scheduling permanent repair — once the storm passes and access is safe, we schedule a full roof inspection and permanent fix.
Total on-site time: usually 60–120 minutes for a typical tarp job.
Why do hardware-store blue tarps fail?
If you’ve bought a tarp at Home Depot or Lowes to cover a leak yourself, it’s probably lasting 24–72 hours before wind or weather defeats it. Here’s why:
Cheap tarps:
- Thin (4–6 mil polyethylene)
- Brass grommets only at corners (wind tears them)
- No UV inhibitors (degrades in sun fast)
- Design assumes you’re laying it on the ground, not stretching it over an angled roof
Commercial roofing tarps (what we use):
- Heavy (10–14 mil reinforced)
- Continuous edge reinforcement
- UV-stabilized (lasts months, not days)
- Fastened with wood 1x4 strapping screwed into the roof deck at proper locations (not just weighted down with bricks)
Result: a properly installed commercial tarp lasts 4–8+ weeks and doesn’t fail during subsequent storms. A blue tarp lasts until the next moderate wind gust.
How much does emergency roof tarping cost?
- Small section (pipe boot area, small flashing): $150–$280
- Medium section (one slope, 100–200 sq ft): $280–$450
- Large section (major damage, 300+ sq ft): $450–$850
- Full-roof tarp (rare, major storm damage): $850–$1,800
All tarp costs are credited toward the permanent repair if you book with us. So a $350 tarp tonight becomes $0 additional cost when we do the $2,800 permanent repair next week.
Does insurance cover emergency roof tarping?
Emergency tarping is almost always covered by homeowner insurance as mitigation — you’re required by most policies to take reasonable steps to prevent further damage. The tarp cost (and even after-hours dispatch fee) is usually reimbursed as part of the claim.
Save the invoice and submit it with your claim documentation. We also provide the storm-date and damage documentation needed to support the claim.
Do you need a tarp, or can it wait?
Quick decision tree:
- Water coming through ceiling RIGHT NOW during rain: tarp now (emergency dispatch)
- Small damp spot that appeared, rain has stopped: wait for morning, schedule regular repair
- Damage visible but no current leak, rain forecast in 2–3 days: schedule within 48 hours, regular rate
- Damage visible but no rain forecast for 7+ days: schedule regular repair, no rush
Not every storm damage needs emergency response. We triage honestly on the phone.
Frequently asked questions
Does insurance cover emergency roof tarping?
Yes, in most cases. Homeowner policies require you to mitigate further damage after a covered event, and emergency tarping qualifies. Save the invoice and submit it with your claim. The tarp cost and after-hours dispatch fee are typically reimbursed.
How long does a professional roof tarp last?
A commercial tarp with wood-strap fastening lasts 4–8+ weeks, even through subsequent storms. Hardware-store blue tarps fail in 24–72 hours due to thin material and no proper anchoring.
Can I tarp my own roof during a storm?
You can try, but it’s dangerous and usually ineffective. Wet roofs are slippery, blue tarps tear in wind, and improper fastening (bricks, sandbags) fails overnight. If water is actively coming through the ceiling, stay inside, catch the water, shut off affected circuits, and call a professional.
Is the emergency tarp cost separate from the repair cost?
No. All tarp costs are credited toward the permanent repair if you book with us. A $350 tarp tonight becomes $0 additional cost when we do the permanent fix.
