Bally, PA Emergency Roofing Services: Temporary Roof Tarp Guide
Estimated Read Time: 11 minutes
Roof leak and a storm on the radar? This guide shows you how to install a temporary roof tarp the safe, right way. You will learn what to buy, the exact steps, and how to avoid common mistakes that cause more damage. If the situation is unsafe or water is pouring in, call Mast Roofing & Construction for same-day emergency tarping and leak sealing.
Before You Start: Safety First
Working on a roof is risky, especially after wind or hail. Wet shingles, fallen branches, and loose decking increase the chance of slips and falls. If the roof is steep, power lines are nearby, or wind gusts exceed 20 mph, do not climb up. Secure the interior first and call a professional.
Key safety steps:
- Evaluate conditions from the ground. If you see sagging, exposed decking, or tree penetration, evacuate that area.
- Use a safety harness, roof anchors, non-slip boots, and thick gloves. A hard hat and eye protection are recommended.
- Use a stable extension ladder that extends at least 3 feet above the gutter line. Have a spotter hold the ladder.
- Never walk on tarps. They are slick even when dry. Plan your exits before you roll anything out.
Local tip: In Berks and Montgomery Counties, oak branches and slate outbuildings create hidden hazards. After nor’easters, shingles and nails collect in gutters and valleys. Sweep walk paths and magnet-scan for nails before stepping.
What You Need: Tools and Materials
Gather everything before you climb. Time and organization reduce your risk.
- Tarp: 6 mil or heavier polyethylene tarp, UV resistant, large enough to extend 3 to 4 feet past the damaged area on all sides. For larger openings, use multiple tarps overlapped by at least 12 inches.
- Fasteners: 1.25 to 1.75 inch plastic-cap roofing nails or 2x4 wood strips with deck screws for a batten system. Avoid ordinary staples.
- 2x4s: Straight, dry pieces for perimeter battens. Pre-cut to manageable lengths.
- Sealant: Roofing mastic or butyl sealant for emergency edge sealing, not as a primary fastener.
- Ladder, harness, roof anchor and rope, chalk line, utility knife, tape measure, hammer or drill-driver, broom, and a magnetic nail sweeper.
- Optional underlayer: Synthetic roof underlayment or heavy plastic sheeting for extra water resistance under the tarp.
Pro fact: Our emergency crews stock heavy-duty commercial-grade tarps for wide spans and use cap fasteners to reduce puncture tears. It is the same approach we use for businesses that need operations protected overnight.
Step-by-Step: How To Install a Temporary Roof Tarp
Follow this sequence to stabilize leaks until permanent repairs are made.
Step 1: Clear Debris and Locate the Damage
- From a secure position, remove loose shingles, limbs, leaves, and nails. Do not pry intact flashing or disturb ridge vents.
- Identify the water entry point and the full affected area. Water often travels along decking or rafters before dripping inside, so the source may be upslope.
If a tree pierced the roof or the deck feels soft, stop. A compromised structure needs professional shoring before anyone steps there.
Step 2: Dry and Prep the Surface
- Sweep the deck and gently dry it with towels if possible. Moisture under the tarp can cause mold.
- Snap a chalk line around the work area to guide your batten placement.
Step 3: Create an Anchor Row at the Ridge or High Point
- Never start fastening downslope. Begin at the ridge or highest point of the damaged area.
- If the ridge is intact, fasten a 2x4 batten parallel to the ridge across the top edge of the tarp. Use deck screws long enough to bite the sheathing but not penetrate living spaces.
- If you are using cap nails instead of battens, drive fasteners every 8 to 12 inches along the top edge, staying in the shingle overlap where possible.
Why this matters: Starting high controls water flow. Any gaps upslope will funnel water under the tarp.
Step 4: Roll the Tarp Downslope and Tension It
- Unroll the tarp down the slope so it extends 3 to 4 feet past all damage.
- Pull it tight, removing wrinkles that can catch wind. Keep your footing clear. Do not walk on the tarp.
Step 5: Secure the Sides With Battens or Cap Nails
- Install 2x4 battens along both sides of the tarp, fastening every 8 to 12 inches. Place battens over the tarp edges to clamp the material without tearing it.
- If using cap nails, fasten on a zigzag pattern 6 to 8 inches from the edge, spaced 8 to 12 inches apart. Add a second staggered row if wind is expected.
- Overlap multiple tarps by at least 12 inches with the upslope tarp on top. Batten through both layers at the overlap.
Step 6: Seal the Downslope Edge and Add a Bottom Batten
- Place a 2x4 batten along the lower edge to create a drip line that sheds water into gutters, not behind them.
- Apply a thin bead of roofing mastic at edges and overlaps to limit wind uplift. Do not rely on sealant instead of mechanical fasteners.
Step 7: Protect Penetrations and Flashings
- For chimneys, skylights, or vents inside the damaged area, cut the tarp to fit and overlap with an additional strip of tarp upslope by 12 inches. Batten around the cutout, keeping fasteners on solid decking.
- Do not remove or puncture intact flashing. The goal is a temporary weatherproof shell.
Step 8: Secure the Interior and Monitor
- Inside the home, set buckets, move valuables, and ventilate to reduce humidity.
- Check the tarp after the first rain. Tighten fasteners if you see billowing. Replace any torn sections.
When a Tarp Is Not Enough
A tarp buys time, but some situations require immediate professional help:
- Structural damage: Sagging rafters, deck delamination, or tree penetration.
- Large or multiple leaks: Water entering from several locations or near electrical lines.
- Steep or high roofs: Multi-story or slate and metal surfaces common around Reading and Pottstown.
- Mold risk: Persistent moisture in insulation or attic sheathing.
Mast Roofing & Construction provides same-day emergency tarping, leak detection, and temporary repairs for residential and commercial properties. Our team installs heavy-duty tarps, reinforces damaged components, and schedules permanent repairs once the weather clears.
Insurance Pointers: Document Everything
You can speed up claims by recording details while you work.
- Take wide and close-up photos before debris removal, after debris removal, and after tarping. Include interior water stains.
- Save receipts for tarps, fasteners, and safety gear. Insurers often reimburse reasonable emergency measures.
- Note the storm date and time, wind direction, and any fallen limbs. Your adjuster may ask for these.
- Avoid permanent changes before the adjuster visit unless safety requires it. Temporary tarping is generally encouraged.
We help homeowners navigate claims with clear documentation and Straightforward Pricing. Commercial clients receive a final quality assurance packet with photos at closeout.
Common Mistakes to Avoid
- Using light-duty tarps that shred in wind. Go 6 mil or heavier.
- Starting fasteners downslope. Water will find its way under the tarp.
- Skipping battens on edges. Cap nails alone can tear out in gusts.
- Stretching tarps over sharp limbs. Cut limbs flush first to prevent punctures.
- Nailing into ridges or hips without checking structure. Use existing sheathing.
- Covering exhaust vents completely. Maintain safe ventilation to reduce moisture and carbon monoxide risk.
Special Considerations for Different Roof Types
- Asphalt shingles: Standard approach with battens and cap nails works well.
- Metal panels: Avoid direct fasteners through standing seams. Use battens secured to the deck at panel flats where possible. Consider professional help for tall spans.
- Slate and tile: Fragile. Do not walk on these materials. Use ladders, planks, or call a trained crew. Our technicians are experienced with slate common in older southeastern Pennsylvania homes.
- Flat roofs: Use heavy tarps with sandbags at the perimeter and temporary mastic at seams. Avoid creating ponding. Commercial-grade tarps can span HVAC curbs and parapets with added battens.
How Pros Handle Emergency Response
Our emergency workflow follows a proven sequence to stop water fast and set you up for permanent repairs:
- Debris removal to expose the true problem area.
- Detailed damage inspection with photos and video.
- Emergency tarping to halt leaks and block weather exposure.
- Reinforcement of decking, rafters, and supports as needed.
- Full-scale repairs or replacements once the structure is stabilized.
For businesses, we add heavy-duty tarping, leak patching, debris cleanup, and documentation to minimize downtime and protect inventory.
What To Do Inside While You Wait for Help
- Move furniture and electronics. Pull area rugs and lift curtains.
- Place buckets and lay plastic sheeting over vulnerable areas.
- Cut small relief holes in bulging ceiling drywall to safely drain trapped water into a bucket. Wear eye protection and keep electricity off in wet areas.
- Run a dehumidifier or set HVAC to dry mode to lower moisture.
After the Storm: Next Steps to Protect Your Roof
- Schedule a roof evaluation. Even if your tarp held, underlying damage needs attention.
- Ask for photos and a written scope. You should see where water entered and what materials will be used for the repair.
- Consider preventative upgrades: improved flashing at walls, new underlayment, or impact-resistant shingles if trees overhang your home.
- Join a maintenance program. Routine inspections catch issues before the next storm.
Local homeowners often face repeated wind gusts through the Schuylkill River valley and freeze-thaw cycles that loosen flashing. A proactive plan saves money over time.

DIY vs Pro: A Quick Decision Framework
Choose DIY if:
- The roof pitch is walkable and the structure is sound.
- The opening is small and contained.
- Weather is calm for the next 24 to 48 hours.
- You have proper safety gear and a helper.
Call the pros if:
- There is structural damage or a tree strike.
- The roof is steep, high, slate, or metal.
- Leaks are near electrical lines or chimneys.
- You need documentation for an insurance claim or a commercial-grade solution to resume operations.
Prevent Leaks Before They Start
- Trim branches 6 to 10 feet from the roofline.
- Clean gutters and downspouts every season. Members of our maintenance program receive 25 percent off gutter cleanings.
- Seal flashings and penetrations proactively. Small gaps become big leaks in a nor’easter.
- Inspect after severe weather. Look for missing shingles, lifted edges, and hail bruising.
A consistent maintenance plan keeps your roof storm ready and extends its service life.

Frequently Asked Questions
How long can a temporary roof tarp stay on?
A good install can last a few weeks, sometimes longer, but it should be replaced with permanent repairs as soon as possible. UV exposure and wind weaken tarps over time.
Should I nail through shingles when tarping?
Yes, but only in the shingle overlap or into decking and with cap nails or battens. Avoid random penetrations. Battens spread the load and reduce tearing.
Will my insurance reimburse the tarp and materials?
Most carriers reimburse reasonable emergency measures to prevent further damage. Keep all receipts and photos. We also provide documentation to support your claim.
Can I tarp a slate or tile roof myself?
It is not recommended. Slate and tile are fragile and steep. A trained crew should handle access, anchoring, and safety on these surfaces.
What size tarp should I buy?
Choose a tarp that extends 3 to 4 feet beyond the damaged area on all sides. For larger openings, overlap tarps by at least 12 inches with the upper tarp on top.
