Are you a metal roofing contractor looking to take your craftsmanship to the next level? Successful installations rely on even, conscientious preparation that starts from the very beginning. Ridge caps may be one of the last steps in most metal roof projects, but if not properly fitted and secured with exact measurements, their installation can easily turn into a nightmare for both contractors and homeowners alike.
Today we’ll provide some helpful tips on getting it right so you can ensure a professional-looking finish every single time. Read on to discover more about how to set yourself up for successful metal roof ridge cap installation!
What is a Metal Roofing Ridge Cap?
Ridge caps are an essential element of any metal roof installation, providing extra protection against wind and water damage. The ridge cap serves as the peak of a roof, where two sides of metal roofing panels meet at an angle, forming a “ridge line” along the top of the roof. Ridge caps are installed on both sides of this ridge line to cover the joint between each side and provide full coverage for this vulnerable area.
Metal roof ridge caps come in many shapes and sizes, but no matter what size or shape you choose, they all do the same job – protecting your roof from wind and water damage.
They are usually made from durable materials such as aluminum or steel that can withstand inclement weather conditions. When properly sealed, these caps also provide an extra layer of insulation to help keep energy costs down.
All in all, installing ridge caps is a relatively simple process that can help extend the long-term life span and durability of your metal roofing system while providing extra protection against water or wind damage. It is important to be sure to use quality materials when installing these caps to get the maximum performance out of them for years to come.

The Two Types of Metal Roof Ridge Caps
The two types of metal roofing ridge caps are closed ridge caps and vented or ventilated ridge caps.
Closed ridge caps are fully sealed along all four sides, providing a tight barrier that prevents water from entering the roof system. This is a great choice for roofs in areas with heavy rains, as they can help keep your home dry inside. Closed ridge caps also provide a more aesthetically pleasing look than their ventilated/vented counterparts since they form one uninterrupted line along the peak of the roofline.
Vented/ventilated ridge caps, on the other hand, have perforations or open slots along two or more sides, allowing air to circulate beneath them which allows moisture to escape from underneath the cap and out of the attic space below. These types of ridge caps are best for areas with high humidity levels where moisture buildup could otherwise be detrimental to your home’s interior space. However, because these openings allow air in, some water can enter your home from outside as well; this is something you’ll want to consider if living in an area with considerable wind or frequent storms.
It all boils down to what you require them for; closed ridge caps are ideal if your main goal is to keep water out, whereas ventilated ones will help allow moisture from the interior of your home to escape. Depending on your climate, one type may be better suited for your needs than another – so take time to research which one will provide you with optimal protection for your metal roof!

How to Install Ridge Caps on a Metal Roof
Installing ridge caps on your metal roof is an important step to ensure your roof is properly protected from the elements. Ridge caps are installed along the ridge line of a roof, providing additional protection and weatherproofing. The installation process can be broken down into several steps: measuring, cutting and finishing, placement, and finally attachment.
Measuring the ridge cap is an essential first step in the process--you will need to measure both the length of the ridge line and its width.
Make sure that the measurements you take are accurate so that your ridge cap fits perfectly when it comes time for installation.
After measuring, cut your ridge cap to fit the dimensions that you have taken. Finally, finish off by smoothing any rough edges or corners with sandpaper or a file.
Once you have finished cutting and refinishing your ridge cap, it is time for placement. Carefully slide each section of the ridge cap over the ridgeline until it reaches its endpoint; make sure to leave enough room between sections for proper expansion and contraction of metal due to temperature changes. After proper placement has been achieved, move on to the final step – attaching the ridge caps securely in place.
The type of closure used on your ridge cap will determine what techniques should be used for attachment - either closed or vented ridge caps typically require different methods for securement.
Closed Ridge Cap Installation
Closed ridge caps usually require screws for attachment at regular intervals along the length of each section – make sure that these screws penetrate far enough into solid wood framing beneath it so as not to leave any gaps between them that could cause leakage in wet weather conditions. Once all screws are securely fastened in place, use tape sealant around their heads and along any gaps between sections of the ridge cap to ensure maximum protection against water intrusion.
Vented Ridge Cap Installation
Vented ridge caps should also be attached with screws at regular intervals along their length; however, they do not necessarily need sealant around their heads or between sections as they allow airflow through them which would render such measures unnecessary. Instead, they often come with their own specialized closures which should be adjusted accordingly during installation according to manufacturer instructions such as those found in product literature or online resources provided by manufacturers themselves – once tightened securely in place these closures will form a tight bond with no gap which may otherwise lead to water intrusion if left unsealed like closed Ridge Caps do require sealing after fastening them with screws.
Installing ridge caps properly on a metal roof can be tricky but following these steps carefully will ensure a secure and successful installation every time! Make sure you always follow manufacturer instructions closely when dealing with specialized closures on vented models so as not to miss out on any necessary adjustments during installation - this way you can rest assured knowing that your roof is fully protected from precipitation even during extreme weather conditions!
