Why the ‘Pap and Lap’ Method Isn’t Enough for Roof Leaks
Danie Reitsma • April 29, 2025

When it comes to roof leak repairs, there’s a common shortcut often used by less experienced contractors known as the ‘Pap and Lap’ method. This approach, which involves simply covering damaged areas with acrylic and membrane, might seem like a quick fix, but it’s far from a permanent solution. At Home Renovations and Repairs, we believe in doing the job right the first time, using proven methods that align with the NHBRC’s specifications to ensure lasting results. Here’s why the ‘Pap and Lap’ approach just doesn’t cut it when it comes to effective roof leak repairs.


The Flaws of the ‘Pap and Lap’ Method


The ‘Pap and Lap’ method is a tempting choice for some contractors because it’s quick and inexpensive. However, this approach is fundamentally flawed for several reasons:

  1. Temporary Nature – Covering a damaged area with acrylic and membrane might stop the immediate leak, but it doesn’t address the underlying cause. This method often fails to fix the root of the problem, leading to recurring leaks.

    2. Lack of Structural Integrity – Roofing isn’t just about keeping water out; it’s also about maintaining the structural integrity of your home.            A quick patch can hide deeper issues like sagging roofs or poorly braced trusses that can lead to costly repairs down the line.

    3. Non-Compliance with NHBRC Standards – The NHBRC (National Home Builders Registration Council) has strict guidelines for roof              repairs, including the proper use of steel flashings, damp courses, and correct mortar mixes. Simply covering a leak without replacing              the faulty materials doesn’t meet these standards.

A Better Way to Repair Roof Leaks


At Home Renovations and Repairs, we take a more comprehensive approach to roof leak repairs that goes beyond temporary patches. Here’s what sets us apart:


  1. Thorough Inspection and Diagnosis
    Every successful repair starts with a detailed inspection. With over 40 years of experience in
    roofing, we have the expertise to identify the true source of a leak. We don’t just cover the symptoms – we address the root cause to prevent future problems.
  2. Replacing, Not Just Patching
    Instead of using a ‘
    Pap and Lap’ approach, we strip back damaged sections, remove deteriorated materials, and replace them with high-quality components like steel flashings and approved damp courses. This ensures a longer-lasting, more durable repair.
  3. Expert Structural Repairs
    If the leak is due to a more serious issue like
    sagging roofs or poorly designed trusses, we have the skills to correct these problems. Our team can reinforce the roof with girders and lattice girders, creating a stronger, more stable structure.
  4. Compliance with Industry Standards
    All our repairs are carried out in strict accordance with
    NHBRC standards, ensuring that your roof isn’t just watertight, but also structurally sound. This commitment to quality sets us apart from competitors who take shortcuts with acrylic and membrane patches.

The Cost of a Quick Fix


Choosing the ‘Pap and Lap’ method might save you money in the short term, but it can cost you much more in the long run. Here’s why:

  • Frequent Repairs – Temporary fixes often lead to recurring leaks, requiring repeated work and escalating costs.
  • Structural Damage – Ignoring the underlying structural issues can result in significant damage to your home, including sagging roofs and compromised roof trusses.
  • Lower Property Value – A poorly repaired roof can reduce the value of your home, making it harder to sell in the future.
