Roof Repairs

You notice a stain on the wall or ceiling.

Paint is bubbling on the walls.

You find a piece of a shingle in your yard.

You see that the roof looks curled up.

There are all kinds of signs that there might be a problem with your roof.

Don’t wait to see if it gets worse. Roof leaks do not heal themselves. They may not drip with every rain or appear to change much but once a leak shows up it continues to let water into your roof whether you can see it or not. That water is slowly rotting the plywood and rafters, allowing mold to form in attic and wall spaces, encouraging insect infestations and attracting animals like raccoons to take up residence in your home rent free.

Please call to set up an appointment so that we can determine what the problem is and can get it fixed before more damage is caused. Time is money in these cases. Getting a leak fixed early will prevent bigger problems and expenses down the road.

A roof leak does not always mean that you need a new roof. If your roof is less than 10 years old, it will rarely need to be redone. I promise you that I will not try to sell you a roof that still has 5 or more years of life left if it can be repaired with confidence.

A good roof should last 20 to 30 years. There are sometimes problems with materials but most of the problems that I see are the result of improper, inferior installation techniques. It is disturbingly common, especially in new tract housing, where cheap materials and installers are the norm.

There are many ways to install a roof and the average homeowner is not going to recognize a good job from a bad one.

There are also proper and improper ways to repair a roof. Beware of roofers with a bucket of tar in their hands. Roof tar can make a good temporary fix but will seldom hold up for more than a few years and will usually begin to be a problem after a year. Roof tar will dry up and shrink and allow water to get trapped in the roof system and cause shingles to prematurely fail.

We will repair your roof properly so that after you have fixed the drywall from the last repair you won’t have to worry about the leak showing up again and putting you back where you started.

Roof repairs can be very difficult to diagnose. Often there will be multiple problems, some of which are not always evident. We will try to determine what the problems are and will take care of the obvious problems first. We try our best to fix the problem the first time but as we are not the ones who installed it we cannot always be sure of  finding every mistake on our first attempt. I will always respond if you have to call us again. I will not give up and leave you hanging.

Some of the most common problems that I see are:

  • Blown off shingles
  • Leaks around chimneys
  • Leaks where a valley ends at a wall
  • Leaks around pipes
  • Ice dams
  • Condensation problems
  • Animal damage
  • Wall flashings installed correctly

Most all of these problems can be fixed and the life span of the roof extended.


Attic ventilation is an important part of the roof system. Proper attic ventilation extends the life of a roof and reduces problems because it minimizes the temperature differential between the attic and the air outside. Proper ventilation will remove moisture and heat from the attic. Trapped heat and moisture can raise energy costs, cause ice dams, and damage roof system components as well as structural and personal items located inside the attic where temperatures can easily reach 150° F (65° C). Condensation that forms inside attics can be caused by the use of washing machines, dish washers, bath tubs, showers, and tumble driers unless these items are properly ventilated through the roof. In some cases the condensation can be bad enough to be mistaken for a roof leak. This is usually a winter time occurrence when the moist air in the attic can condensate on the plywood and actually form frost. Repeated years of this will damage the plywood.

Ventilation of the home attic is important for many reasons. During the summer, excess heat that builds up in the attic during the day results in high energy costs for cooling.

Also, moisture produced within the home may move into the attic if ceiling vapor barriers are not used. If this moisture is not exhausted from the attic it can condense and cause insulation and construction materials to deteriorate. Thus, temperature and moisture control are the major reasons for providing attic ventilation.

There are many types of attic vents available today. There are static vents, power vents, ridge vents, turbine vents, soffit / cornice vents, gable vents, starter vents, and cupola vents. These all come in a wide variety of sizes, styles and shapes. Some will ventilate better than others depending on the roof configuration, attic size, climate, etc.

Attic Ventilation is a process of air intake and output. The flow of air is critical to promote good ventilation.

Below are just a few of the commonly used ventilation systems used by G. Klemm Roofing, Co.

Ridgevent - Installed at the peaks of the roof, this product allows for added efficiency at the highest point in the attic where hot air tends to become trapped. Ridgevent is popular because it is barely visible after installation, removes the hot, trapped air in the highest attic areas, has no moving parts, and gives the ridges of the roof a unique look.

There are numerous brands and styles of ridgevent on the market. A lot of them do not work very well and some actually allow moisture to enter the attic in high wind situations. The ridgevent we use is ShingleVent II made by Airvent.  (see www.airvent.com for more information)  

The Low Profile and Turtle vents are static roof vents.  That means they have no moving parts. Most homes have these vents. The low profile vent is typically smaller than the Turtle vent but they both work well and are easily installed.

Power ventilation can be accomplished in two ways. In homes not mechanically cooled (air conditioned) the temperature can be controlled to some extent by the use of attic fans. These fans are usually ceiling mounted in a central hallway so that outside air is pulled through open windows and exhausted through the attic. Sufficient outlets must be installed in the attic to exhaust the air without creating high pressures against which the fan must operate. Air conditioned homes can use power attic ventilators by installing an exhaust fan through the roof or in the gable. Inlets for the ventilating air should be at the soffit, or the opposite gable, when no roof overhang exists.

Power ventilators have the advantage of providing good ventilation even when there is no wind. They also provide limited attic temperature control when installed in conjunction with a thermostat.

When it comes to ventilation, more is always better. Choices are many in ventilation. Dormer vents are another way to go. They are simple and can be installed out of sight at the rear of the building.

Proper roof ventilation in your new roof may be the difference between a successful, long-lived roof or a complete failure in a very short period of time. Considering the high cost of re-roofing the average home, a few hundred dollars for additional ventilation should be considered a very wise investment indeed.

Call G. Klemm Roofing, Co. to see if your roof ventilation is sufficient.

Ice Dams 

An ice dam (or ice jam) occurs when water builds up behind a blockage of ice. Ice dams can occur in various ways. Ice dams may not be avoidable, but you can prevent a leak from ruining your home. You need to understand how an ice dam can form to know how to minimize potential roof leak problems. 

An ice dam is a block of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas. 

Although individual cases look different, and often result in different types of damage, all ice-dam situations have two things in common: They happen because melting snow pools behind dams of ice at the roof's edge and leaks into the house; also, ice dams and the damage that results from them is avoidable.

Ice dams are most common in northern climates.  They occur when heavy snow buildup melts during the day and then refreezes when temperatures drop overnight. After several days of melting-freezing cycles, it's common for the melted water and ice to work up under the shingles until water enters the attic and eventually does damage to the ceilings, wall and contents.  In cases where the ice dam goes unnoticed for an extended period of time, it can do significant damage to the building and its contents.

However, there are products available, when properly applied, will minimize or eliminate the leaking caused by ice dams. There are also design features that you can incorporate into your structure to minimize or eliminate the water from entering your living space.

Proper insulation and roof ventilation can stop ice dams from forming, prevent damage and lower energy bills.

Although ice dams can form anywhere on a roof, they form most readily at the bottom edge of roofs, valleys and areas where the slope might change on a roof.

There's no way to guarantee an ice dam won't damage your home, but you can take steps to cut the chances of an ice dam forming in the first place:

o       If you haven't already, thoroughly clean all leaves, sticks and other debris from your home's gutters and down spouts.  This lets melting roof snow flow into gutters and through down spouts, just as they were designed.

o       Make every effort to keep snow on your roof to a minimum. Keeping heavy snow loads off your roof reduces the chances for both ice dam formation and roof failure due to the weight.

o       All winter long, keep gutters and down spouts clear of snow and icicles.

o       Evaluate the insulation and ventilation in your attic.  Most experts agree that the R-value of attic insulation should be at least R-30 (R-38 is preferable in northern climates).  In addition, good airflow from under the eaves or soffit area along the underside of the roof and out through the roof vents is essential.  The insulation prevents heat loss from the interior of the home.  The venting allows the attic air to stay cold enough to prevent or minimize the freeze/thaw cycle on the roof.  Consult a reputable roofing and/or insulation contractor about these improvements. 

o       In an emergency situation where water is flowing into the house structure, call an experienced roofing contractor.

Reroofs  (aka overlays, 2nd layers, recovers)

 There are 2 things to look for:

  1. Longevity
  2. Apperance

In my opinion it is always better to remove the existing roof layers. This is especially true for flat roofs. But despite the fact that a total tear off is the best choice, I understand that this is not always practiced and/or affordable. Saving money is important but what most home owners do not know (and a lot of contractors for that matter) is that there are many crucial details that need to be done to prevent serious problems down the road. These details require time. Unfortunately, a lot of these details are not addressed at all. The contractor does not detail the specific treatment to be used on the walls around the chimney and in valleys. He’s going to do things “his way” in affect selling you a cheap roof. The problems caused by improper installations on a reroof do not often show up within the first year, but these areas do not have proper flashings. They are actually letting water in between the two layers from day one. It is not uncommon for a leak to become apparent after 5 years or longer (I know, we repair them a couple hundred times a year). By that time your guarantee will be over. And if you call the original installer he’ll probably not be too concerned, if your lucky he’ll come back to smear some tar on it, if he comes back at all.

Don’t settle for a cheap roof. The low price may sound attractive but there is one reason. If you want to get the most out of your roof, DO NOT GO CHEAP! Get it done right.

I was going to explain these details with pictures and descriptions of proper installation techniques but I know that the majority of the roofing companies doing even know what they are doing wrong. I don’t want to teach them. (This would be a good place for one of those smiley faces).

The other important thing that I want to say about a 2nd layer is that you should only go over and old roof if:

  1. The roof boards or plywood is solid and mold free.
  2. The shingles are not excessively curled or it’s an architectural shingle.
  3. The pitch of the roof is 4” in 12” or greater.

The only real candidates for a reroof are a standard 3-tab shingle. These shingles have what we call a 5” exposure. This means that the shingles are spaced at 5” intervals all the way up the roof. For this reason we recommend an architectural (or dimensional) shingle manufactured by “Tamko”. The Heritage 30 (or 50) is the only remaining shingle that still has a 5” exposure. Some years ago the other manufactures all switched to a metric measurement that has about a 5 5/8” exposure. When these 5 5/8” shingles are put on top of a 5” shingle there is a pattern of ridge that shows up horizontally every 4 or 5 feet. This is not a good look.

If you are considering a recover/reroof on your house you should ask the contractor for a list of jobs that you can look at. Look at the recent ones but also look at some 5 year or older roofs. This will really show you the contractors quality of work.

Another point that needs mentioning: Try to find out who the applicators on your roof are going to be. Are they employees? Are they subcontractors? Do they get paid by the job? Are they properly insured (ie; workmans comp.)? Are they legal employees? Are they properly trained? If a problem or concern should occur will any of them be able to understand and properly answer your questions?   All of these things are what sets G. Klemm Roofing apart from the others. All of our employees are professional, polite, hard working, honest americans.  All of our employees are properly trained & insured. Our employees are paid on an hourly basis. When employees are paid by the job it means that production speed is most important to them and reflects on their paychecks. Quality then becomes an afterthought and usually not the only one.

Call G. Klemm Roofing and have it done right the first time.



Flat Roofs



A skylight is a special type of window built into the roof of a house in order to allow natural light to come into the house directly. Nearly everyone likes skylights. They let in light and warmth, provide a convenient place to hang indoor plants, and simply brighten up an entire room.

Aside from providing natural day light, skylights can also help in minimizing heating, cooling, and lighting costs. A skylight may be installed for artistic purposes, or as part of a general heating strategy. Skylights are also designed in a variety of shapes and made from many different materials.

Properly installed, roof skylights can add a touch of class to even a rather drab kitchen, bathroom or other room in your house. However, old and leaking, or incorrectly installed roof skylights are a never ending nightmare that will have you swearing never to have another skylight in your house.

Some of the different Skylights we install are:

  • Ventilating skylights: Are opened to allow air to pass through. These skylights are ideal for bathrooms and kitchens, where they help to relieve excess moisture and keep the low of air steady. Ventilating skylights may be controlled by a remote, by a hand crank, or by an automatic sensor which tracks inside temperature.
  • Fixed skylights: Any type of skylight which doesn't open. This type of skylight is intended solely to allow light to pass into the house.
  • Flat skylights: Probably the most common, consisting of a square or rectangular piece of flat glass or acrylic, which may be fixed or ventilating. A round skylight emerges from the roof as a half-sphere bubble. A polygon skylight peaks up out of the roof with a number of glass or acrylic polygons-these skylights are more expensive than simpler models, but are also very artistic impressive.
  • Pyramid skylights: Is a simple four-triangle pyramid which juts out of the roof.
  • Dome skylights: Similar to a flat skylight, except that the glass rounds up past the surface of the roof.
  • Tubular skylights: Use renewable energy natural light to light interiors, such as hallways, small rooms where a traditional skylights wouldn't easily fit. They're easier to install than typical skylights and, from the home's interior, resemble light fixtures.

 We can assist you in choosing the most appropriate materials and design for your roof, in accordance with your climate, so that your skylights will be both energy efficient and a lovely addition to your home.




Residential roofing is typically made up of a multitude of materials and surfaces whose primary task is to maintain a barrier between the interior and the weather. The most pervasive and difficult weather element to control is water. Roof flashing is usually the last line of defense in the battle against water penetration.

Flashing forms the intersections and terminations of roofing systems and surfaces, to thwart water penetration. The most common locations for roof flashing are at valleys, chimneys, roof penetrations, eaves, rakes, skylights, ridges, and at roof-to-wall intersections.

Flashing must be configured to resist the three mechanisms of water penetration: gravity, surface tension, and wind pressure. To achieve this, flashing can be lapped shingle style, soldered or sealed to function as a continuous surface, or can be configured with a non-continuous profile to defeat water surface tension.  

Flashing materials made of galvanized steel, copper, or aluminum direct water away from valleys, chimneys, vent stacks, skylights, and where dormers and other walls meet the roof. Flashing is also required along eaves and rakes (the ends of a gable roof). Newer membrane materials and modern sealants are available that complement time-tested techniques.

Flashing materials must be durable, low in maintenance requirements, weather resistant, able to accommodate movement and be compatible with adjacent materials. Common modes of failure include exposure to salt air, excessive heat, acid rain, heavy snows, and scouring winds.

The weather is a relentless bully. It seems to focus its stormy strength on a home's most vulnerable areas, attacking over and over again until rain and moisture infiltrates, and eventually damages, the home. Because a home's roof takes the brunt of the attack, it's critical to protect vulnerable areas of the roof against the elements, especially rainfall.

The most vulnerable areas of a roof are where the sloped roof meets a vertical wall, like the wall of a dormer window, or where a garage attaches to the two-story section of the house. If no water management strategies have been applied at the roof-to-wall transition, water can enter the home at this area, which can cause serious damage. Wet building materials can lead to mold growth, known to cause respiratory problems, and can lead to wood rot, which creates structural concerns.

The best practice for protecting these vulnerable areas against rain and moisture intrusion is to use step flashing integrated with the shingles.

The term flashing refers to both a material as well as a process. You can find flashing materials made of plastic, roofing felt, and rubber, but your best bet is rust-resistant metal, either galvanized steel, aluminum, or copper. The process of installing the flashing requires close attention and is a critical element to ensuring proper water management of the roof.


When it comes to the comfort of your home, the amount of insulation in your attic can be a big factor. Current costs of energy continue to rise. With additional insulation you may be able to save up to 20% on your energy bills. Over time insulation can settle, in affect losing the R- Value that it had when new. Installing a loose, blown-in, fiberglass insulation over the top of the existing product is a simple, cost-effective solution.

You can also visit the Owens Corning website to see the AtticCat insulation system that we use.  www.owenscorning.com

Roof insulation should always be installed according to industry standards, safety requirements, and optimal functionality conditions. For this you will need the assistance of a roofing professional. We guarantee that our roof insulation services will bring you lasting insulation comfort of the highest quality, and a roof insulation solution that will cater to all your needs and budget.
