Roof Inspection

Time for a Roof Inspection!

Early-October in Colorado - Time for a Roof Inspection!

If you’re a veteran in the commercial roofing business, the Fall season is a simple reminder that everything begins to fall on a roof during the summer, and well into the pre-winter months.

A commercial roofing system is one of the largest investments an owner will make in their company, and United Materials is here to assist in the education, protection, and preservation of that asset, as well as everything and everybody under its roof!


We encourage stakeholders across the board – from owners to Facilities Managers – to conduct seasonal roof inspections, and make those all-important repairs before the snow falls. Let’s work together, and focus upon a few subtle and not-so-subtle roof locations that will require a little extra focus this month and next. A tight roof means a safe roof, which means the people and equipment beneath the roof will be kept safe and dry.

Most commercial buildings have flat roofs, and fallen leaves may do a great deal of damage if not removed. Leaves retain moisture, and may lead to them degrading into a soaked and weighty mass. And what follows commonly includes:

► Obstructed drains

► Blocked scuppers

► Growth of mold, mildew, and fungus

► Backed-up water leading to additional weight

► Organic debris that may permeate into your roof system in other hazardous ways

Above all, these things lead to damaged roofing material, and leakage.


Along with the inspection and removal of the above items, it’s just as important to maintain drains and pipes atop the roof, and their drainage points at the ground level. This is where grounds keeping and facilities maintenance meet! Preventing standing water on the roof is crucial!


Select a cool and completely dry day for your roof evaluation. This will give perspective on where dry sediment and debris tends to gather. Also, be sure to check for splits; splits near vents, stacks, growth joints, walls and the perimeter. When temps continuously rise and fall, contraction repeatedly occurs.


As mentioned, checking your roof in the Fall offers the chance to check for damage brought on by the summertime sun, such as roof blisters. Roof blistering occurs when air is caught between the layers of felt, or between the felt and substratum. When the air heats, it moves, as well as triggers the splitting of felts. Roof blistering can lead to a slit, revealing a blister break. Water will pass right through!


When you work with United Materials, you’re working with a partner who will assist with this important inspection. We can help to evaluate each aspect of your roofing system. Aside from this list, there are a dozen smaller details that only a roofing professional can inspect. It also takes a skilled eye to acknowledge early problems with sealants, flashings, mortar, seams and penetrations. We’ll also check rain gutters and downspouts (that may be sagging), loose connections or damaged or missing fasteners.

Take a minute to call us at 303.623.4166, and certainly don’t wait for a simple inspection to turn into a costly repair. Delivering peace of mind is a specialty of ours. Let’s all enjoy a winter viewed from inside a warm and dry building.
