How Much Does Roofing Cost?

When it comes time to replace your old worn out shingles or you may have had a storm damage your shingles the first question that always comes to mind is… how much is this going to cost me?

Roofing Costs

It is a fair question and it is important to all of us. Most of us just want a good job for a reasonable price. First of all, not all roofs are the same as far as roofing products and installation difficulty are concerned. And not all roof installer charge the same price. There are two factors involved in the cost of roof replacement, the cost of the roofing material, and the cost of labor.

In figuring your roof replacement the price generally includes the removal of the old shingles, roofing underlayment, dumping fees and the replacement of new underlayment and similar new replacement shingles. This may also include metal flashing, ice and water shield, starter shingles and metal drip edge. You may expect to pay more for a 30 year asphalt dimensional shingle than a 25 year 3-tab asphalt shingle. You can also expect to pay more for roof replacements in coastal cities due to stricter code regulations and in housing developments with high end specialty roofs.

Replacing roofs with roofing products such as slate, wood shingles, clay tile, concrete tile, and metal will cost you more to replace than the commonly used asphalt shingles would. Asphalt shingles make up about seventy percent of all roofs in the United States. Some other things to consider when calculating the cost of a roofing job should be the type of shingle being replaced, geographical location of the home or business, local codes and regulations, pitch and roof difficulty, and roof design and roof style.

Just the cost of installation alone, not counting the cost of material, will vary from state to state. Roofers who have been in business longer with a proven track record may be able to charge more. Some roofers may charge more according to additional services they offer such as extended labor guarantees and repair warranties. Some companies may charge more because of their nationally known name recognition. Others may charge more because of their advertising, advanced roofing equipment, and well-staffed offices.

The cost of replacing roofs can vary greatly and it cannot be assumed that one price fits all.  According to, who provides cost guides, comparisons, and term cheat sheets for hundreds of remodeling, installation and repair projects, calculates the average cost to replace a 1500 square foot roof using architectural shingles in the United States is $9,000.00. That is an average cost of $6,000 to $14,000.

But the bottom line to the question “how much does roofing cost” will be something you have to research on your own, in your own city or town by shopping costs with several roofing companies. Get several bids from reputable roofing companies to get the feel of what the going price is for your location.

Roof Repairs to Ventilation

Roofing Ventilation

Ever feel like you need to vent? Things just heat up inside you until you feel that you must have a release? At one time or the other almost everyone have. Most people don’t function well under that kind of duress. Well, without proper ventilation your roof is the same way. It doesn’t function the way it should either without a well-designed ventilation system.

During the summer months the space between the building structure and the peak of the roof heats up, and in the winter months it is the opposite.  The idea of venting the roof is to remove or get rid of the hot air in the attic during the summer time, and in the winter to maintain the proper temperature of the roof structure itself. How well the ventilation system works for keeping the desired temperatures inside the interior of the house or building by a number of factors.

Control The Temperature

The most important factor to keeping a desirable temperature inside the interior of a structure is the insulation on the floor of the attic. Other factors are the types roofing materials used. The decking, and if it has an insulation space itself, for instance a grid between the decking and the roofing panels. Another factor would be if there is sheathing on the inside of the attic space on the ceiling and walls.

As for the ventilation system itself there are several types that work extremely well. The homeowner will need to do his or her research to determine which one will serve their needs the best. No one type of ventilation system is better than another. It all depends on the roof design and climate in the region.

One popular type of ventilation is the” low profile or turtle type” vent system. They are the most uncomplicated and inexpensive of the ventilation systems. They have no moving parts and simply allow hot air to escape as it rises to the top of the roof ridge where they have been installed.

Roofing Ridge Vent

Another type is “ridge vent.” Ridge vent runs along and over the length of the ridge on the roof. The ridge vent system folds over the ridge and also is assisted by vents on the underside of the soffit to draw the airflow inside the attic from the soffit to the ridge where it is released.

A professional roofing contractor can give you a free estimate on installing ridge vents on your home or business. Good roofers can install the roof vents and be done in a day.

Still another type is the “wind turbine.” It operates by the wind blowing inside louvers which causes it to turn drawing the hot air out of the attic. How many turbines are needed on the roof is determined by how much space you have in attic. They should be installed near the top of the roof in order to catch the wind blowing.

Still another is the “power vent.” Power vents have an electric motor that turns a fan that draws the heat out of the attic. Most power vents have a thermostat that turns the unit on when it reaches a certain temperature. Because the motor requires electricity it will have to have an electrical power source installed. There is also a “solar power” vent which works the same way only powered by the sun.

Go ahead and vent. Trust me you’ll feel better.

Shed Roof Repair

So you finally decided to do something about that shed that’s been leaking for years now.

No question that there is damage to roof shingles and the decking. So here’s the question. So should I call someone out to repair the roof on the shed? Or, should I get brave and do the repairs myself?

DIY Repairs

Well if you have the extra money to spare then definitely call a roofing company or a qualified handyman. But if you want to save the money, and you have a little confidence as a DIY kind of person then…  “you can do it!”

First, do an inspection of the shed and determine if you can do a few small repairs or if you need to remove the old shingles and decking and replace the entire roof. Are there just a couple of shingles missing or loose that is allowing the roof to leak? Or, is the roof shingles weathered, deteriorated, curled and appear to have reached its life span? The inspection will let you know the extent of the damage and cost. Then make a list of the tools and materials that you will need to complete the job.

Repairing Missing Shingles

If you are just repairing the roof you can simply replace the damaged or missing shingles one at a time. Lift up the shingle just above the damaged shingle, remove the nails from the damaged shingle and remove it. Then slide the new shingle back into place, nail it down so that the shingle above it will cover the nails in the new shingle and if needed use a little roofing cement to hold the top shingle down on the new one. If you have nails holes just fill them with roofing caulk to stop the leak.

If you decide to replace the roof entirely then you should remove all the shingles and felt from the decking. Note: you may need to replace the decking as well if it is water damaged or disintegrating. Next you need to make sure the decking is clean and free of any debris. Make sure all the existing nails have been removed. Start at the left hand corner of the roof and roll out your new felt working from left to right. Overlap the felt 2 to 3 inches until it is fully covered.

Roofing The Shed

Use a starter shingle with an overhang of ¼ inch past the edge on both sides of the roof. Now start your three-tab shingle starting at the left hand corner and nail it over the starter shingle. Complete the row with however many shingles that it takes using four to six nails per shingle. On the next row cut off six inches from the first shingle so the tabs will be staggered and complete the next row. Continue on until both sides of the roof are covered.

For the ridge, determine how many shingles you will need to cover the ridge from one end to the other. Center the ridge shingles evenly and nail them into place so the next shingle covers the nails and complete the ridge by cutting off the excess at the end of the roof line.
