Metal Roof Service: Screws Backing Out

A common concern that homeowners express is when they notice backing out screws in their metal roof. Many customers choose a metal roof for its longevity and easy maintenance schedule. We often receive calls from customers who purchased a metal roof a few years ago from one of our competitors. These customers may have had the roof for several years and just performed a five year walkaround to inspect their roof for damage or leaks. On their inspection they notice several small leaks appearing inside on the top floor. Confusion arises as to why their roof is failing after only a few years.


During their inspection, the customers noticed a few roof screws are jutting out more than normal. They also see that most of the screws are stripped and can not be tightened any more. This is what we call “backing up screws”. Screws backing up occurs very often with improperly installed metal roofs. This is especially true in areas that are cold in the winter and hot in the summer.


We recently had this exact telephone call from Chris and his wife Debrah.  New Roof Repair customers located in Lewisburg, PA in Union County. Chris and his wife had purchased and installed a beautiful metal roof from a contractor in Williamsport. This contractor quoted a very low price by skipping the teardown of the old roof. They didn’t remove the old shingle roof and just built the metal one above the old roof. In order to make the quote so low, the contactors avoided the roof teardown and didn’t use the recommended underlayment. This resulted in a cheap, improper roof installation with a propensity to leak after a few years.

Reasons Metal Roof Screws Backing Out

Improper roof installation


By cutting corners with budget materials and incomplete installation, they greatly increased the likelihood that their roof would spring a leak… Additionally if the contractors crew is inexperienced they may quickly screw in the fasteners too deeply with power tools. It pays to take your time during the install because the screws may pierce too deeply into the bottom layer.

No Visual Inspection

Without the structural integrity of your metal roof, a strong winter will cause damage. Ice Dams may form due to improper attic ventilation or gutters clogged with ice and debris. These “Ice Dams” form with the constant freezing and thawing of snow and may grow very big and heavy. This extra weight will damage the screw heads and cause them to back out.


Cheap Materials or Not Enough


Too few screws will also allow wind under your roof in certain places. This wind will slowly start to pull you roof upwards and cause the fastener screws to back out. Budget materials are cheap, but prone to leaking. Budget materials will create holes if they experience extreme temperatures. All roof materials must be rated to handle the roof expansion and contraction in hot and cold weather.
