Temporary Roof Patching: What Works, What Doesn’t, and When to Call a Pro

When storm clouds gather over Merrimack, NH, and the skies open up, nothing is more alarming than discovering a roof leak. Living in New Hampshire means dealing with sudden summer storms, gusty winds, or fallen branches—putting your home or business’s roof to the ultimate test. If you find yourself in a roofing emergency, knowing which temporary patching methods will protect your property until help arrives can be the difference between a small repair and costly water damage.

Let’s break down what works (and what doesn’t) for temporary roof patching, highlight when it's time to call a trusted roofing professional, and answer a question many Merrimack residents search for: “Can I make a temporary roof repair myself, or should I always call a contractor?”

What Actually Works for Temporary Roof Patching?

Quick action is essential when you notice a leak or missing shingles. Here are effective temporary patching methods that can help you weather the storm:

• Plastic Sheeting (Tarp Method): One of the most reliable temporary fixes is heavy-duty plastic sheeting or a tarp. Securely fasten the tarp over the damaged area using roofing nails or weighted boards. Be sure to extend it well past the affected zone to divert water safely.

• Roofing Tape or Sealant: For smaller gaps or cracked shingles, roofing tape or waterproof sealant can hold back moisture for a short period. These materials adhere well and provide a solid, water-resistant barrier.

• Roofing Cement: If you have a small puncture or gap, roofing cement can be applied with a putty knife to plug the opening. This can buy you valuable time until a professional inspection.

Keep in mind that these methods are designed as stopgap measures. Especially under New Hampshire’s unpredictable weather, a DIY patch should be promptly followed up with a thorough inspection and permanent repair.

Don’t Fall for These Temporary Fixes

Not all “quick fixes” are created equal. Here are common DIY methods that Merrimack homeowners should avoid:

• Duct Tape: While duct tape might seem handy, it won’t withstand rain or UV exposure for long and can actually trap water, worsening roof damage.

• Caulking All Over: Overapplying generic caulking in the wrong places can block ventilation or cause moisture buildup.

• Using Household Plastics: Thin plastic or garbage bags are prone to tearing in wind or rain, leaving your property vulnerable.

• Heavy Objects as Weights: Placing bricks or heavy items on a tarp is risky—wind can send them crashing down, damaging your roof or creating hazards.

Should You Attempt a DIY Roof Patch?

"Can I make a temporary roof repair myself, or should I always call a contractor?" 

This frequently asked question has a nuanced answer. Minor, accessible damage—like a missing shingle or small leak—can sometimes be temporarily addressed by a confident homeowner using safe methods. However, if:

• The leak is spreading or water is pooling inside
• The damage is close to electrical fixtures
• There are structural concerns or large sections affected
• You feel unsafe accessing your roof.

It's best to contact a local professional like A-Z Roofing. Roofing work always involves risks, and improper repairs can void warranties, increase damage, or create safety issues.
