How to Prepare Denver Commercial Roofing For the Winter


November 29, 2017

Temperatures are starting to drop, which means fall is coming to an end and winter is right around the corner. Preparing for the winter season can mean many things for many different people. For commercial property owners, part of preparing for winter involves getting roofs ready for the change in the weather. Here’s how commercial property owners can prepare Denver commercial roofing for the winter:

Inspect the Roof

The first step to preparing your roof for the winter is inspecting it for potential problems. What should you look for? Look for obvious signs of damage, such as holes or puncture marks in the roofing material. Run your hands across the areas where sewams meet. If the roofing seams are open or if the material is coming apart ,contact a professional right away.

Pay close attention to the flashings, which are metal, plastic or same as the matereial in the field. lt is typically located around the pipes, vents, and HVAC system on your roof. Flashing can start to deteriorate, become loose, or crack if it has reached the end of its lifespan. If you spot any of these signs, call a roofing professional. If the flashing is damaged, water and snow can easily make its way inside your building, which can cause a big problem.

Another area that you need to inspect closely is the edge of the roof, especially if you have a flat roof. The flashing that attaches the roofing material to the edge of the building should be in good condition. If it’s not, this needs to be addressed right away. Worn down flashing located at the edge of your roof could blow off during a winter windstorm. To prevent this problem and protect your property, have the flashing replaced before the weather gets bad.

Many commercial property owners perform these roof inspections on their own, but it’s strongly recommended that you hire a professional to do so, especially if you don’t know much about roofing. If you perform the inspection on your own, it’s possible that you could miss a potential problem or seriously injure yourself while on the roof.

Clean the Gutters

Hire a professional to visit your commercial property and clean the gutters before winter arrives. Why is this important? The snow that falls on your roof will eventually melt, and this water will need to be able to drain off of your roof quickly. If the gutters are clogged with dirt and debris, the water will have no place to go so it will remain on your roof. Sitting water can weaken roofing materials and lead to leaks. In some cases, the water can become so heavy that it causes part of the roof to collapse. This can be a headache, not only because it’s expensive to repair, but also because it could interfere with your ability to operate your business. To prevent this problem, simply schedule a gutter cleaning in the early days of the winter. See tips for cleaning and repairing gutters.

Review Insurance and Warranty Information

Commercial property owners should take the time to review their insurance and warranty information just in case a roofing problem arises during the winter. First, make sure that you are up-to-date with insurance payments so you don’t try to make a claim for roof repair only to find out that your policy has lapsed. You should also review the details of your coverage to make sure you understand what is and is not covered under your current policy.

Next, take a look at the warranty or guarantee that you have on your roof. Is it still in effect or has too much time passed since the roof was installed? If it’s still in effect, review the details of what the warranty or guarantee covers. You should also make sure that you are doing everything you are supposed to do under the terms of the agreement. For instance, if the agreement states that the property owner must schedule two roofing inspections per year, make sure that you are complying with this term so you don’t accidentally void the warranty or guarantee. Keep these documents in a safe place during the winter so you can quickly access them if a problem arises.

Take A Look At the Trees

Before winter officially arrives, take a look at the trees on your property to see if any of the branches need to be trimmed to protect your roof. Keep in mind that snow can start to accumulate on tree branches over the winter, which could weigh them down and cause them to snap. These sharp, pointy branches could puncture or damage roofing material on your building, which is why it’s so important to trim them before they become a problem.

Create An Action Plan

No matter how long you spend preparing, it’s possible that something could damage your roof in the winter. For this reason, it’s a good idea to create an action plan that outlines exactly what will happen if a roofing problem is discovered. This is especially important if you are a landlord who rents out the property to a commercial tenant.

Who should be checking the roof for signs of damage throughout the winter? Who is responsible for getting in touch with a roofing professional? Will the business temporarily close while the repairs are made? These questions all need to be answered in your action plan to make sure everyone that you work with is on the same page.

Most Common Problems With Commercial Roofing in Denver


Commercial roofing materials are not indestructible, so they will eventually have problems. It’s important for business owners to know what problems they should expect so they know how to spot the signs of an issue and when it’s time to contact a professional for help. Here are some of the most common problems that may arise with commercial roofing in Denver:

Leaks

A commercial roof may develop a leak for a number of reasons. Roofs must be designed with water drainage in mind, meaning the roofing professional who installs your roof must figure out where and how water will drain. If there is no drainage system, water that falls on the roof will have nowhere to go. The longer that it sits on the roof, the more likely it is that the water will seep through the roof’s membrane and start leaking inside your building.

Leaks can also start to form if the roof is starting to wear down because of its age. A commercial roof can last anywhere from 15 to 50 years, depending on the type of roofing material that is used. As you get closer to the end of the roof’s lifespan, the materials may start to deteriorate and leaks may start to form.

If you spot puddles of water inside the building or dark-colored stains on the ceiling, this indicates there is a leak in your roof. Some property owners are able to smell a leak before they see it. If you smell mold but can’t figure out where it’s coming from, this could be a sign that the roof is leaking.

Thermal Shock

One problem that many property owners are unaware of is thermal shock, which is most likely to occur in the beginning of winter when the days are warm and the nights are cold. The roofing system will expand slightly when it is exposed to warm temperatures, and then contract when it is exposed to cold temperatures. Roofing systems that are exposed to both warm and cold temperatures within the same day will expand and contract as the temperatures change throughout the day. But, this puts a lot of stress on the roofing materials, especially if they are already worn down due to their age.

It’s recommended that you look for the signs of thermal shock if the temperatures have been high during the day and low at night. If you see any cracks or buckling in your roof, call a professional for help. You should also pay close attention to areas with flashing, which may become loose after expanding and contracting repeatedly.

Ponding

As previously mentioned, sitting water can lead to roof leaks. But in some cases, the sitting water may become so heavy that it causes the entire portion of the roof to collapse. “Ponding water,” which is water that sits on a roof for longer than 48 hours, can cause a great deal of damage. Every inch of ponding water on your roof weighs an estimated 5 lbs. per square foot. The heavier the ponding water becomes, the more stress it will put on the roof and the structure of the building, eventually causing the roof to collapse.

This is a much more serious issue than a tiny roof leak, so it’s important for business owners to understand how to spot the signs of this problem. Although the National Roofing Contractors Association defines ponding water as water that has been sitting on a roof for more than 48 hours, sitting water can actually do damage before 48 hours has passed. For this reason, it’s strongly recommended that you work with a roofing professional to ensure there is an effective drainage system put in place so water never sits on you roof. See 10 common commercial roof problems.

Punctures Caused by Foot Traffic

Property owners with single-ply or spray polyurethane foam roofs need to be especially careful to avoid punctures caused by foot traffic. If there are constantly people on your roof performing maintenance checks or repairs, it’s possible that the heavy foot traffic could lead to punctures in the roofing material.

Most roofing professionals know to install extra layers of membrane in areas where there are bound to be a lot of foot traffic. But even if you have these extra membrane layers, it’s still a good idea to restrict access to the roof to cut down on foot traffic. This doesn’t mean you should skip inspections or delay roof repairs, but don’t let anyone on the roof that does not have a valid reason to be there.

Blistering

Blistering is another common problem that may arise on your commercial roof, although it is typically only found on built-up roofs (BURs). Blisters are pockets of trapped air or moisture that form between layers of the roof’s membranes. As the blisters become larger, they will start to stretch the membrane further and further. Sometimes, the blisters will grow so large that the membrane will crack from the pressure.

Blisters are fairly easy to spot as long as you take the time to glance at your roof once in awhile. A blister will make the surface of your roof appear uneven and lumpy. If you spot blisters on your roof, call a professional even if the blisters appear to be shrinking in size. Blistering is a reoccurring problem that will not go away unless it is fixed by a professional. A roofing professional will most likely need to cut through the layers of membrane until he has reached membrane that has not been stretched out. Then, new layers of membrane will need to be installed to make the roofing system whole and effective again.

The Difference Between Denver Commercial Roofing Warranties and Roof Guarantees


Many people use the terms “warranties” and “guarantees” interchangeably when discussing Denver commercial roofing repairs, but these two terms have very different meanings. Every business or commercial property owner should understand how these two terms differ so they know what type of protection they have if an issue with their roof arises. Here’s what you need to know about commercial roofing warranties and guarantees:

Types of Warranties
There are two common types of warranties that cover commercial roofs. The first is a manufacturer’s material warranty, which is issued by the manufacturer of the roofing materials. This type of warranty typically provides protection from 10-30 years depending on material used. This can lead many commercial property owners to think that they are covered if they ever need roof repair. But unfortunately, that’s not necessarily true. A manufacturer’s material warranty will only cover the product if it is defective. For example, if the membrane on a TPO roofing system shows early signs of failure because it was installed next to window glare, it may be replaced under this material warranty.  However most issues arise due to the installation of the roofing materials, not the manufacturing of them. As a result, many commercial property owners are surprised to learn that their warranty does not cover many types of repairs. What does your roof warranty cover?

The second type of warranty is known as a NDL warranty. A NDL warranty is issued by the manufacturer of the roofing materials. A NDL warranty states that the manufacturer agrees in some respect to cover any repairs caused by defective roofing materials and labor.  In some cases the first two years after completion, the repairs are at the cost of the installer. After the initial 2 years the manufacturer will cover both material and labor for the remaining years of the warranty. If things don’t work out this way when a problem does arise, the manufacturer will be on the hook for the terms of the warranty.

There are a few loopholes that a manufacturer or installer can use to get around the terms of a warranty. Don’t just assume that the manufacturer or installer will do the right thing if a roofing issue arises. To avoid these problems, look for an installer that offers a roofing guarantee to customers along with the manufactuers material warranty. Its always best to get the NDL warranty, but they are usally only offered with a commercial project, and only an Authorized or Certified Installer of the product manufacturer can offer them. 

The Basics of Roof Guarantees
A warranty is filled with terms that exclude certain types of roof repairs and severely limit coverage. Often times a guarantee does not have many of these limitations or exclusions. An installer that offers customers a roofing guarantee is agreeing to cover the costs of any repairs that arise due to the materials, labor, or installation process. This means a roofing guarantee will cover everything from defective roofing materials to a problem that arises due to the improper installation of the roofing materials. For this reason, it’s in your best interests to look for a roofing company that offers customers this type of guarantee.


Finding the Right Roofing Guarantee
Many companies may offer roofing guarantees, but don’t take them at their word. You should always ask for a copy of the roofing guarantee before agreeing to do business with the roofing company. Ask for a copy of the guarantee from each company that you speak with so you can compare them and determine which offers the most coverage. This is one of many factors that you should consider when deciding which local roofing company to hire.

How do you know which company has the best roofing guarantee? There are a few things you should look for when comparing roofing guarantees from different companies. First, look at the time frame of the guarantee. How long will you be covered by the guarantee? If the guarantee only lasts 1 -2 years, then it may not do you any good. You should also pay attention to the dollar cap on repairs. Each guarantee will specify how much the roofing company will cover when a repair is needed. For example, a guarantee may state that the roofing company will pay $1,000 towards any covered repair. This means if the repair costs $1,500, you will be responsible for paying the $500 balance. Look for a roofing company that offers a guarantee with a high dollar cap on the covered repairs.

Next, find out if there is a fee for coverage under the guarantee. Some roofing companies ask customers to pay a one-time or annual fee for coverage under their guarantees. This is something that you will need to know when comparing guarantees from different companies to ensure you choose the best one.

Finally, read the terms of the guarantee to see if it discusses the cost of labor. Some guarantees will state that although the cost of the repair is covered, the cost of labor to make the repair is not covered. This type of guarantee basically asks commercial property owners to pay for a portion of the repairs that the guarantee is supposed to cover. 

Authorized Installers/Roofing Companies
Only accept and take bids from roofing companies that are authorized or certified from a manufacturer.  There are many roofing manufacturers in the market, and although not all are created equal, they do most of the homework and investigations of the roofing companies for you. Most manufacturers will only offer NDL warranties on behalf of the highest, and most qualified roofing companies.
