Four Signs Your Commercial Roof May Not Make it Through the Winter

Your commercial roof may not make it through the winter. It happens every winter when roofs collapse, spring leaks, or get damaged in a storm. Knowing the signs in advance will help you save the roof and save you money too. At Chaffee Roofing, we hear about roof problems every day. Our years of experience help us help our clients and prevent those problems from getting worse. We put some of the more common signs of these problems into a post, which should benefit all commercial roof owners. To help you know the signs that a commercial roof may not make it through the winter, take a look at the following points. Sagging across the roof Probably one of the more obvious signs is a sagging roof.  Get up on the roof and take a quick look around. If rainwater is gathering in pools, then you have a sagging roof problem. The deeper the pond, the bigger the problem. Sagging roofs can quickly develop into huge problems. Rain, snow, and hail can gather in pools and put a lot of extra weight on the roof structure. Your roof may collapse under the pressure, or you may get additional leaks around the building as the roof system stretches and expands beyond its design. The added weight of a heavy winter snowfall can be a disaster for […]

Four Benefits of Having Your Commercial Roof Inspected

The benefits of having your commercial roof inspected far outweigh the costs involved. Indeed most annual inspections cost very little, especially when you compare them to the cost of the problem. At Chaffee Roofing, we do plenty of annual commercial roof inspections. We recommend completing them on any roof because the benefits are so obvious. Sometimes clients are a bit skeptical, so we put a post together to help the skeptics see the way. As a reminder to inspect your commercial roof, let’s take a look at some of the following benefits. Detect leaks Leaks can happen anytime and anywhere. It does not matter how good the roofing material is; a bit of unexpected damage may let the rain or moisture leak through the roof. We sometimes see the results of a bad installation project. Maybe the wrong adhesive was used, or just poor working practices left gaps in the roof. A qualified, professional contractor is worth the money, so be careful with cheaper alternatives. An inspection will look for these problems. The commercial roof needs caring for and a bit of maintenance every year.  The smallest defects can cause the biggest problems. Find them before it is too late. How is the roof aging? A commercial roof will have a natural lifespan. If you care for it, the roof will reach its target and […]

Choosing The Longest Lasting Commercial Roofing For Harsh Winters

Winters are harsh on commercial roofing. All of that rain, sleet, snow, ice, and wind will do damage. Often business owners think their roof is strong until a night of wind and rain brings leaks and damp patches. The weight of heavy snowfall or a week of ice will cause its own problems. A harsh winter will expose weaknesses, often with devastating results. At Chaffee Roofing, we know the benefits of a long-lasting commercial roof. The type of roofing to come through the winter and withstand the toughest conditions is what you need. Let’s take a closer look at the best roofing for your building. TPO is one of the best roofing solutions for harsh winter problems. We supply EPDM, TPO, and PVC membrane roofing materials for commercial installs. All three products have their benefits, depending on the style of the roof. TPO is one of the best for harsh winters. It has many benefits, and for commercial roofs going through harsh winters, TPO covers all eventualities. Not shattering is one of the major benefits of any roof in a harsh winter. Instant, low temperatures can cause a roof to shatter, often overnight. This will not happen with TPO, and you can rest assured when the coldest nights come that your TPO roof will stay secure. Shrinking is another problem with cold and freezing conditions. […]

Heat – Welded PVC And TPO Seams Do Away With Seam Weaknesses

A flat roof is only as strong as its weakest seam. Many types of seams are not strong enough under pressure and will fail. Age, foul weather, and even poor application by badly trained roofing mechanics can cause a seam to open. Once the seam opens, the membrane separates, and the next rainfall will do the damage. At Chaffee Roofing, we know that properly installed heat-welded membranes fix the problem of seam weakness. Our years of experience tell us how both PVC and TPO give peace of mind when it comes to solid roofs.  Let’s take a closer look at how not to have roof seam weakness become an issue. It’s all in the welding Both PVC and TPO membrane seams are heated-welded together. The rolls of membrane slot into place and our highly-trained Chaffee Roofing technicians go into action. We use robotic welders on large, open plan roofing installations. The onboard computer automatically sets the correct temperature for the material. Hot air welding, using temperatures up to 800 degrees, seal together the seams of the membranes.  The computer also sets the correct pressure to apply and the most suitable speed when welding together the PVC seams. The bonding process creates the strongest seal possible in roofing systems. How about the tighter roof areas? While the robotic welder is ideal for the larger roof areas, […]

Types Of Commercial Roofing That Are Installed Over Your Old Roofing

Does your old commercial roof need replacing? Are you considering installing a new roof over the old one? Are you worried about choosing the right roof for your building?  We see projects where removing and disposing of the old roof is as big a job as installing the new one. The solution can lie in installing the new roofing over the existing one. There are types of commercial roofing systems that allow you to do this without any trouble. When done correctly, the finished roof is as strong and reliable as any new installation. Let’s take a closer look at the types of commercial roofing to install over your old roofing. TPO will install easily over the old roof TPO is one of those materials which fits easily over an old commercial roof.  The heat-welded seams do not leak, and the TPO does not shrink under the summer sun.  A significant advantage of TPO is puncture resistance. If you have a lot of foot traffic on your roof, then TPO is for your building. A team of qualified roofing technicians will install your new roof and leave you with a much-improved structure. Shingles can be difficult We often get calls from clients looking to replace a shingle roof. A major expense can be the removal and disposal of the old shingles. Yes, it is possible […]

Extending The Lifespan Of Your New Commercial Roof

How do you extend the lifespan of your new commercial roof? It is a very important question to ask when you make that big investment in improving your property. Get the answer right, and you will get the return you deserve, but get it wrong, and you are throwing money away. Based on its cost and importance, you should care for your commercial roof. A new roof is a new start in protecting your building and putting a lot of old problems behind you. Let’s take a look at how you can extend the lifespan of your commercial roof. Keep roof drains, gutters and scupper boxes clean A significant amount of people fail to keep leaves and debris out of water outlets. This causes drains, gutters, scupper boxes, and other water outlets to get clogged, causing a variety of problems. This can include damaging the underlying insulation, water running over counter-flashing details and into the building, or even water running off the side of the building, which wears down siding work, painting work, etc. Scheduling an annual cleaning from a roofing contractor can keep so many problems from developing. People always ask if they can do this themselves. With basic cleaning, the answer is typically yes if you are capable of doing so, but we can tell you from experience that 99% of people forget. […]

Tapered Insulation – How Does It Work?

On buildings designed with little to no roof pitch (i.e., slope to direct water toward drains, scuppers, etc.), or older buildings that may have settled over time, ponding water can be an issue. Depending on how much water ponds on the roof and how long it stays there, solutions are usually developed to help promote drainage. One of the most common solutions is tapered insulation. But how does tapered insulation work? The first step is always to determine the severity of the problem. If ponding water is minimal, then installing a tapered insulation system may be overkill. Adding drains, scuppers, or even installing relief outlets can solve smaller ponding water problems at a fraction of the cost. However, if ponding water is problematic throughout a large portion of the roof system, tapered insulation should be considered. The next step is to obtain information on the existing roof system. This starts in the field, obtaining roof measurements and identifying sources of water relief. Drains, scuppers, gutters, etc. all need to be identified and measured out relative to the building. That way, when the tapered system is designed, we know where we are trying to direct the water. Once information is obtained, the next step is to create a design. Typically, a design starts around the drains and works its way towards the edge of the building. […]

5 Signs You Should Replace Versus Repair Your Roof

Knowing when to replace a roof is a very valuable skill. You may do repairs through the many years of its life, but there comes a time when replacing the roof is the only option. Getting the timing right is vital.It will save you money.Looking for signs of replacing rather than repairing is the place to start. Five clear and obvious signs leave nothing to doubt.Let’s take a look at the five signs that indicate you need to replace your roof. The roof is marking its 25th anniversary Age catches up with a roof. All those years of being exposed to cold, wet, and windy weather, as well as hot summers, take their toll.Take a look at when the roof went on the building. If it is 25 years or more, annual repairs will most likely not be enough on a standard roof system.Repairing a 25-year old roof is not cost-effective on most roof systems. The roof is sagging in too many places When a roof begins to sag, you know you are in trouble. Typically, it means that the underlying insulation is in very poor shape or, in extreme cases, the structural wood or steel decking is beginning to collapse. If the contractor can repair a weakness, then you may be safe for a few years.When the roof as a whole begins to sag, […]

Benefits of HD Insulation

On many of our quotes and proposals for a new roof system, an option is presented for ½” HD insulation. Oftentimes, the additional cost may be similar to upgrading to a thicker membrane or even upgrading to more insulation. So what is HD insulation, and is it worth the additional cost? HD insulation is a stronger version of standard polyisocyanurate insulation, which is the most common type of insulation installed on flat roof systems. The difference is that standard polyisocyanurate insulation is 20 PSI, and HD polyisocyanurate insulation is 80 PSI to 120 PSI, depending on the type and manufacturer used. So, it is somewhere between 4 to 6 times stronger than standard insulation. So why does the strength of the insulation, which is under the roof membrane, matter? It provides a stronger surface for the new roof system to be installed over, which helps reduce punctures and support the membrane overall. The best way to visualize this is to think of a piece of paper. If you try to write on it on a soft surface, or even no surface, the pen will go right through the paper. If you write on a solid surface, like a wooden desk, the paper doesn’t puncture. With HD insulation, it’s a similar concept. It’s harder to puncture or damage the roofing membrane if the underlying insulation has […]

EPDM Seams and Flashings – What’s Changed?

EPDM has always been known as one of the most durable roofing products available. Its high UV resistance and ability to stand up to weather over time has made it a very popular flat roofing product, decade after decade. Its ability to resist ponding water on roofs has also made it very popular as a man-made pond liner, among its many uses. However, EPDM has always had one big weakness: seams and flashings. Alternative single-ply roof systems, like TPO and PVC, can be heat welded. If completed correctly by a knowledgeable crew, a heat weld is the strongest bond available. It essentially welds the flashings and seams together with the base PVC or TPO membrane. With EPDM, heat welding isn’t possible, so the seams are instead bonded together with adhesives. In the early days of EPDM, seams and flashings were only expected to last 10 to 15 years. The reason was the technology they had at the time, which was a product called splicing cement. On most early EPDM roof systems, the seams were glued together using this method. Some manufacturers used caulking products to hold off water penetrating the seams, which could help buy some time. However, after a period of time, the result would always be the same – open seams and flashings. The cure to this problem was an expensive one: re-do […]
