Paul Link asked:


Lead work can be found on many roofs, for example as flashing, or in valley gutters between roof sections. Lead roofs on the other hand refers to large sections of a roof, or a whole roof being covered in lead sheet / milled lead / machine cast lead. This is something that most people would associate with churches and cathedrals; indeed it is likely to be a feature of many grand old buildings, and many large modern structures. However, in recent times, theft of lead (among other metals) from the roofs of buildings has seen a massive increase. Quite simply and obviously, the reason is money.

Is this really a problem?

Yes. Recent examples of large scale theft of lead from roofs in the UK include the 100 square foot hole in the top of the 800 year old roof of a church in Leicestershire, and the estimated £30,000 of lead stolen from a Leicester entertainment complex roof.

The root cause - economic factors

So why has the value of lead increased to the point where some people are prepared to steal and cause great damage to property in order top get it?

The lead on the roofs of your local buildings is now likely to be at risk because of international economic changes such as:

Huge demand for lead in countries experiencing rapid industrial growth such as China and India has increased the price of lead on global markets sevenfold in only six years.

Supply problems e.g. from Australian mines, have pushed prices up further.

Some example figures

The figures we’re talking about for lead are approx £2000 / $4000 per ton last summer, although it’s now nearer approx £1500 / $3000. It is worth remembering however that iron and steel still account for approx 80% of the recycled metal in the UK. Scrap metals firms which were traditionally smaller family owned businesses, have benefited from rising metal prices to the point where the largest UK scrap metal merchants are now estimated to be worth more than £1 billion. Global scrap metal prices are set to increase again next year, and the UK metal recycling business is estimated to be worth £1.9 billion.

Insurance companies, such as those specialising in ecclesiastical insurance have had a massive increase in claims, payouts e.g. for theft of lead from roofs, and this has obviously resulted in increased premiums.

What measures can we take to stop lead theft from roofs?

Installing fences or obstacles around buildings, increased use of security patrols and equipment, greasing drainpipes around buildings (a real example), and even marking the lead roof with security inks may help in the fight against thieves. So what could the ultimate deterrent be?

The ideal answer

Quite simply, a roof without lead. Install a roof that looks like lead, but is not lead. Often, the large lead surfaces on older buildings are on a flat roof. Modern membrane roofing e.g. Sarnafil, looks like lead in appearance and colouring. Special battens or mop sticks can be added beneath the roofing material to make it look even more like traditional lead roof designs. Specialist flat roofing companies using roofing such as the Sarnafil 5 point system (single-ply flat roofing systems) can very quickly install a roof that is in character with the building, and provides affordable, complete waterproof protection for decades. A Sarnafil Roof Assured flat roof installation for example could last over 40 years according to the British Board of Agrément. Contact a specialist flat roofing supplier to discuss how you could defeat the lead roof thieves once and for all.

You would have heard and read many articles on roof repair and its preventions but this article will discuss factors to be considered while going for roof repair and reproofing decisions. Roof repair is one issue just about every homeowner frets about. Water leaking into a home can cause serious damage in a short amount of time. Just one leak from one storm can cause an entire drywall ceiling to fall dropping mushy gypsum board and messy fiber glass insulation onto you and your possessions.

Roof leak repair doesn’t have to be scary. There are tough roofs to work on no doubt. Attempting roof repairing on a steep slate roof repair should be left to the professionals. The same is true for metal roof repair or even tile roof repair. These are tricky materials to work with. But you should be able to successfully do home roof repair if you have a low-slope roof, a cool day and the right attitude.

The most important factor in any roof repair job is which contractor you choose. A good roofing contractor will check the area surrounding the leak in your roof for any sort of water damage. They should be able to let you know whether or not there is rot or water damage present, and whether or not it’s bad enough to need repair immediately. In today’s economy, cost is another important factor for roof repairs. There are many types of roofs here in Miami, and each type is going to have a different price range for repairs depending upon supply cost and availability of experienced contractors.

Roofs may need replacing for several reasons.  It may be leaking and be more economical to replace rather than repair it.  The roof may not be working correctly or does not look good.  Another reason for replacing the roof may be because you are extending your home and want the roof to look fully uniform.

Over the past 45 years, EPDM single-ply roof systems have grown consid­erably in market share compared with their modified bitumen and built-up competition. As a result, there are many aging EPDM roofs, and consultants will be faced with the task of providing cost-effective, durable solutions to keep the roofs in proper work­ing order without tearing them off entirely.

Several factors come into play and impact consultants’ decisions regarding the end of a roof system’s useful life. Thermal bridging, proper drainage, R-value, surface color, wind uplift, and hail resistance are all important factors to consider. When every­ thing is taken into account, consultants are faced with two primary choices when addressing an aged EPDM roof besides a complete tear off and replacement: restora­tion and re-cover.

EPDM roof restoration usually encompasses reworking the flash­ings, seams, and terminations, while leaving the field membrane in place. EPDM is well known for its long-term wea­therability, so in most cases the field mem­brane has life remain­ing. This option is used primarily when the owner wants to extend the life of the existing roof or warranty cover­ age for an additional five to ten years. EPDM roof re-covers provide the ability to address more issues than typical restora­tions. Proper drainage, thermal bridging, en­hanced R-value, al­tered surface color, as well as enhanced wind uplift and hail resis­tance, are all issues that are better ad­dressed with a roof re­cover.

The cost of roof coatings is typically about 50% of that of re-roofing and the benefits are very tangible;

substantial reduced cost over re-roof reduction in cooling costs with 80% reflectivity years of longevity given to the existing roof minimal disruption to the work environment during its application minimal waste going to landfill annual reduction in cooling costs as high as 22% no toxic odours or vapours ease of future repairs no increase in roof weight load

reduced long term maintenance and roof repair costs

My dad helped me get into my house by fixing roof repairs that needed to be made. He put a new roof in and applied new torch down but he did not put a fiberglass membrane down. It rained and now there are leaks in both of the areas that he “fixed”. Is the fiberglass membrane essential to maintaining the water-tight integrity of a roof using torch down?

Jordan FeRoss asked:


You need a roofing job done on your home or business, and while looking through the phonebook or internet you find that some Dallas or Fort Worth roofers and roofing repair companies are listed as either commercial or residential roofer. Maybe even some claim to do both! What’s the difference? A roof is a roof, right? Well… not so much.

The first thing that differentiates a residential roofing job from a commercial roofing job is the type of building the roof is for. Just because you bought what used to be a house and turned it into an office for your real estate company doesn’t make it a commercial roof. On the other hand, the roof of an apartment complex might just classify as a commercial roofing job even though it’s a residence. If you’re unsure on if the building you need re-roofed classifies as residential roofing or commercial, call the Dallas or Fort Worth roofing company you have in mind and ask.

Another difference between commercial roofs and residential ones would be the size of the job itself. How many square feet is the roof? How many workers will the Dallas roof repair company need to send to your location to do the job? Many residential roofing jobs only require a single contractor, where as commercial roofing jobs typically require a whole crew.

Many commercial buildings also have a lot more protrusions than a residential building. A residential home will typically only have a chimney jutting out. A commercial building, on the other hand, may have smoke stacks and ventilation systems and pipes, and mechanically wiring, and a roof entrance, and a skylight, etc. All these pose obstacles for the roofer, and in some cases so much that a crane has to be called in to aid with the job. Restaurants especially have lots of external machinery on the roof which can cause problems for the contractors doing the roof job.

Unions also factor into what makes a commercial job different from a residential one. Many roofing companies are a part of a union so that they can get the higher paid unionized commercial roofing jobs. Many unions will not allow their members to work union jobs. This is the case for most roofing jobs. A commercial roofer with a union can’t work the non-union residential job, because his union and labor costs won’t allow it.

The products and tools needed for the job can make a difference too. A residential roofer might not have the tools required to handle the bigger scale job of a commercial roof efficiently. They might also not have adequate manpower. There are even new developments in the roofing industry that are bringing about products designed especially for commercial roofing jobs. Products like rubberized roofing materials which are phasing out hot roofing.

So first, you’ll need to find out if your roof is residential or commercial. Most of the time it will be obvious (a house VS a mini mall), but for those that are closer to being both, check first. Also, make sure that once you know what kind of roofing job yours is, that you hire a roofing company capable of doing that type of job.

Webmaster Epdmcoatings asked:


When we start talking about roofing problems, the first thing we need to know about is types of roofs prevailing in the market and the pros and cons of each roof type. Whilst Roofing is constantly exposed to the elements, structural shifting, and stresses as well as chemicals in the atmosphere all take their toll on your roof. Aging occur on all roofs, wear and tear stemming from neglect, abuse, contamination, and accident can result in expensive repairs or premature failure of the roofing system, if not detected. A Regular inspection program will help detect minor problems before they become big ones, avoiding interruptions of work going on inside the building, and most importantly, protecting the owner’s investment and adding many years to the life of a roof.

Roof Types:

Wood: There are two types. Shingles are cut to a specific size and smooth finished. Shakes are irregular and rough-textured. Wood gives a natural look to a home. It also requires more maintenance to protect it from the elements.

Metal: Metal roofs have returned from the olden days to become a popular roofing option. Once limited to low-slope structures, standing seam steel roofs can now be used on steeper roofs as well. Metal is durable, practically maintenance-free, heat reflective and non-flammable. Installed in sheets, a metal roof will actually dissipate a lightning strike rather than conduct it.

Built-up Roofing: Built-up roofs are installed on flat or very low-sloping structures. They consist of alternating layers of felt or fiberglass treated with asphalt. These layers are topped with asphalt (tar) or aggregate. Built-up roofs are more common in commercial buildings.

Tile and Slate: These are two of the oldest roofing materials around. They are long-lasting and durable. Their weight requires a reinforced roof structure that can support them. Both can be quite expensive and neither is easy to install.

Slate Roofing: is a very expensive choice, but it’s very beautiful and distinct. Many Colonial and French homes look very appealing with this style of roof materials. Slate roof materials are heavy, as you can imagine, and will need additional structural support.

Factors that affect roofs

• Sun delivers a combination of ultraviolet rays and heat can prematurely age a roof.

• Snow or ice that melts and refreezes (called ice damming) pushes up the roofing material and causes leaks. Ice damming can be a temporary problem that ends when the thaw is complete. Excessive amounts can damage the roof and roof structure.

• Rain is normally kept at bay by a roof. But when rain or moisture gets underneath roofing, damage can occur.

• Wind can remove any roof in the most extreme occurrence. However even minimal amounts can weaken a poorly installed roof by letting dirt and moisture get underneath.

• Moisture from condensation underneath a roof not only harms the roof and sheathing, but also can cause problems inside of the house.

• Trees provide shade to help cool a house. They also provide leaves and limbs that can fall or scrub against the roof.

• Algae and moss get a foothold on moist surfaces. Excessive growth can retain moisture and cause eventual weakening of the roofing material.

Other Causes of Roof Problems:

• Improper Installation

• Improper Design

• Lack of Maintenance

• Flashing Failures

Each of these major causes of roof damage can be minimized by regular and careful inspection for early and minor problems. Immediate attention to any flaws or damages with competent repairs can help you avoid major damage to your roof and prevent the need for early and costly roof replacement.

Having a roof that leaks is a very common problem of many homeowners, especially if you live in an area that sees a lot of rain. When your roof leaks there are a lot of problems that can happen such as mold and mildew stains, damaged foundations, and water stains on the ceiling, just to name a few. Because of this it is important for you to have the knowledge of how to find the leaks in your roof.

When you do discover a leak in the roof you should not panic but simply know that it is time to fix the leaky roof. A leak can actually be a good sign as it will force you to check the leak and it is a good idea at this time to look over the entire roof to see if there are any other leaks or problems. Fixing a leak in your roof is not very expensive and it does not take a lot of time.

The Common Roof leaks problem can best be solved by using EPDM. It is compatible with all types of roof problems caused by sunlight, snow, moisture, rain wind and other causes etc. EPDM is the broader term among roofing material used for repairing, it includes liquid rubber. EPDM is compatible with almost all types of roof including flat roof, sloped roofs and other times of roofs mentioned in this article.
