Cost To Reinforce The Roof

How to replace garage roof in the rain

In some cases, a qualified professional may reinforce the roof structure, including damaged trusses. In general, these types of repairs apply only to roof trusses with minimal damage that does not compromise the overall strength of the truss.

Most contractors qualified to repair or reinforce a roof truss wont estimate the repair cost. Examining the damage often doesnt reveal problems until the repair or reinforcement has begun. For this reason, most contractors will quote on a cost-plus basis. The cost is a combination of the cost of the materials plus an hourly charge. Typically, the hourly charge for these kinds of repairs averages $55 per hour.

How Much Does A New Garage Roof Cost

The cost of a new garage roof will depend on the size of your garage. The condition of your roof structure and your choice of roof covering will also affect the cost. A garage roof replacement cost in the UK can vary anywhere between £750 and £3600.

A professional roofer will remove the old felt from a roof and ensure the timber structure is in good condition. If the timber is rotten, it will need replacing before re-felting the roof. If any of the garage roof sheets need replacing, the cost of garage roof sheets is approximately £40 each. Each plywood sheet measures around 2.4 m x 1.2 m. You will have to add that expense to the final cost.

Up to now, weve only spoken about standard roofing felt for garage roofs. Up to a decade ago, all flat roofs were made with bitumen felt and asphalt, but that is no longer the case. These days there are more options available. EPDM and GRP fibreglass have become very popular over recent years. Although EPDM garage roofs and GRP fibreglass garage roofs are superior compared to felt and asphalt roofs, its worth noting that modern roofing felt has advanced a great deal. Modern roofing felt has a longer life expectancy thanks to modern technology.

How Much Does Replacing A Flat Roof Cost

The average cost of a flat roof is anywhere from £1000 to £5000. This seems like a rather wide range, but this is due to all the factors that affect the price. For example, depending on the type of flat roof you opt for, the price could either reduce or increase.

There are other factors to consider, including the size of the house, the labourers expertise, and the ease of access to the roof. This is all in addition to other considerations like scaffolding and so on.

The material used on the roof is one other factor to consider. There are four most commonly used materials in flat roof construction: felt, rubber, fibreglass, and lead. For instance, if you opt for a felt roof, you can expect to spend between £40 to £70 per m2.

Its worth noting that replacing a flat roof can fluctuate in cost as it is affected by several factors, which we will discuss in more detail. The most crucial factor is the size of the house and what section you want the flat roof placed. For example, a flat roof for a one-bedroom apartment is between £1500 to £3000.

Also, note that this is assuming the flat roof will act as the main roof. However, if you are on a budget, you could use the flat roof for a section of the house like the garage, in which case, the price could come down to somewhere between £700 to £1000.

One other factor that affects the price is the materials used for construction. For instance, a metal roof generally costs more than one made out of rubber.

Roof Replacement Cost By Pitch

Asbestos Garage Roof Replacement

Your roofs pitch also impacts the replacement cost. Pitch refers to how fast the surface rises from the edge to the top. This measures height gains for every 12 inches. Most people have a conventional pitch, which includes styles like gable, cross gable, hip, Dutch, dormer, shed, butterfly, and M. It also includes the top portions of gambrels and mansards. A pitch falling between 4/12 and 6/12 is considered conventional. Pitches falling between 0/12 and 2/12 are considered flat, while 2/12 to 4/12 is considered low. Most low-slope roofs are treated like flats in material and cost. High or are 7/12 and greater. These are seen on A-frame homes and the sides of a mansard and gambrel.

Below are the average cost ranges for the most common materials used on these roofs. Only conventional and steep roofs can use the most common materials, while flat and low-pitch areas need different materials. It is also important to remember there are other less-common materials available with higher costs.

Cost To Replace Asphalt Shingle Roof

Replacing an asphalt roof with new shingles will cost between $5,400 and $9,000, or an average of $7,211 for a 2,000 square foot home not including old roof removal. The actual cost will vary depending on whether it is a composite asphalt shingle roof or a fiber cement composite shingle installation.

Asphalt is the least expensive solution, with a cost to remove the previous asphalt roof and install a new one coming to $7,850 for a 1,500 square foot home, while the same project undertaken and installing concrete shingles instead of asphalt will cost $24,950.

Location Of The Property

The cost of living in large cosmopolitan cities is pretty expensive. This usually has a knock-on effect on other things, including food, and, in this case, labour costs. Therefore, if you live in a big city, a new flat roof cost could be higher than initially expected.

This is also true in rural areas as the availability of competent tradespeople might be hampered due to the location which could lead to an increase in the price.

Also, if your home is distant from the company or tradesperson coming over to embark on the project, this could increase. This is due to the common practice of contractors billing clients from the moment they leave their offices or workshops. Therefore, a long commute could end up costing you a lot of money.

Here Are Some Questions To Ask A Roofer Before You Hire Them

A garage refurbishment doesnt come cheap. It makes sense to ask a few questions beforehand to make sure you are hiring a qualified tradesman. Here are four questions you should ask before hiring anyone.

1. How many years experience do you have? Replacing slates and tiles is one of the basic skills of a roofer. But, have they had any training and have the qualifications to install a new flat roof using new technologies?

2. Ask the roofer if they can provide you with a few references from recent jobs they have completed. Get in touch with the references and ask them about their experience hiring this roofer.

3. Make sure you ask each roofer for an accurate quote. You dont want a roundabout figure over the phone. You want to get at least 3 accurate quotes from three different roofing companies.

4. Always keep in mind that the cheapest quote isnt necessarily the best. If the quote is much lower than the others, it might be a sign of a lack of experience, or he missed a vital part of the job. Be aware of sneaky, underhanded sales tactics. One of the most common sales tactics is to give you a low estimate at first, then add more items to the bill at the end.

Cost To Replace Roof Trusses With Rafters

Replacing a garage flat roof

Replacing a trussed roof with rafters can make sense if the original rafter designs are not available for the truss company. However, if your roof trusses are simple, they will usually cost much less than framing rafters on site. Framing rafters for a new roof typically costs between $13,500 and $22,00.

The size and complexity of the roof are the two factors contributing most to roof rafter construction costs. You may also incur costs for an engineer to draw a roof framing plan if your local building code requires the drawings for a permit.

How Many Shingles Will Your Roof Need

Once youve determined all of these various measurements, you should have a good idea of how many shingles your roof will need for a replacement. Remember that shingles are sold in 100 square foot increments known as squares and that your roofs square footage is affected by its pitch.

Once you find your pitch, and the total number of square feet for your roof, you can determine the number of squares you need by dividing your final number 100 and rounding up to the next whole number.

Dont be discouraged if you need something like 8 and a half squares its a good idea to have some shingles from the same lot as your roof on hand in case of future repairs. Shingles can vary in color from lot to lot, which can make a patch or repair job stand out if you needed to order additional shingles, so always round up and save your extra in case its needed later.

Roof Replacement Cost By Material

The material has a tremendous impact on the total cost of the materials and labor. Some materials are exclusive to the roof type you have. For example, a flat-topped home uses specific materials that are not used on conventional slopes. However, most homes use asphalt shingles, metal panels, tiles or shakes made of several materials, or specialty materials like cedar or slate.

Each material has costs. The more features a material has, the higher its costs. For example, architectural shingles that help protect against hail damage have a higher cost than standard architectural shingles. Clay tiles cost more than concrete, while copper costs considerably more than aluminum. Rare materials like slate and copper cost more due to their availability. Materials that are harder to install, such as wood and some clay tiles, also have higher costs. Materials with additional benefits, such as energy efficiency, algae protection, hail protection, or rainwater management, also have higher costs.

When choosing a material, consider its costs, maintenance, and longevity. While slate is very expensive, it can last 200 years or more in the right circumstances with little maintenance. This can make it more of an investment than a less expensive material.


Roof Replacement Cost By Material Type

Many people use asphalt shingles, but you may also have a roof made of any number of different materials.

Keep in mind, however, that if you opt for a heavier roof than what you currently have, that it may cost you more, simply because you may need to have your frame reinforced.
