General Roofing Costs
Overall, roofing repairs tend to fall into the following price ranges:
Minor repairs: approximately $150 to $400.
Moderate repairs: approximately $400 to $1000.
Major repairs: approximately $1000 to $3000.
This means you can expect a rough average cost of around $650.
If you receive a quote for over $3000 it’s likely time for a complete roof replacement. In this instance, you are looking at a larger quote, likely exceeding $7000.
But it’s definitely a good idea to calculate the roofing cost by the square foot, as set out below.
Roofing Costs by Square Foot Per Material
Roofing costs will differ depending on the material you need for your roof.
The materials come in different levels of price-point, and so the square footage also varies dependant on said material.
The most common roof type in the US is an asphalt shingle roof – which also happens to be the least expensive to repair or replace.
The average price to replace an asphalt shingle roof is around $7 per square foot to install. Per 10 x 10 square-foot, you’re looking at between $500 and $1000 for a moderate repair, based on the average US roof size of 2000 square feet.
If your roof features wood shakes or cedar shingles you’re looking at a repair costing around $500 to $1000. This might be due to the build-up of moss or damage due to insects that live in the wood. There are also metal shingles, which would be around the same price.
A whole new asphalt shingle roof would be around $7500.
These cost an average of $500 to $1500 to repair. Metal roof damage can involve the fixing of loose seams or damaged fasteners.
The average price for a new metal roof would be double an asphalt roof
A 1000 square foot metal roof will therefore come in at between $5000 and $8500
So a 3000 square foot metal roof will come to between $16,000 and $27,000.
Fascia and Soffits
Depending on how large your roof is, the average cost to repair fascia and soffits is $3000.
You can replace fascias with PVC or wood ($10 to $30 per 8-foot board) and soffit panels come in at approximately $20 for a 12-foot board.
These parts of your roof are subject to damage because they are often more exposed to the elements.
Roof trusses average around $1.50 to $4.50 per square foot. They are important as they support the whole roof and can actually stop more substantial leaks from penetrating the roof.
They can develop mold, which can be dangerous to health, so if you spot this then you’ll need them inspected.
Clay and Concrete Roofs
For clay and concrete roof, the prices come out as follows.
For a 1000 square foot roof, it will cost between $12,600 and $24,000.
For a 2000 square foot roof, you’re looking at a low end of $18,000 and a high end of $42,000.
For a 3000 square foot roof, it will cost between $24,000 and $45,000.
Slate and Stone Roofs
Often the nails on a slate or a stone roof can come loose, leading to the need for moderate roof repair.
It’s likely you’ll be looking at a quote of between $550 to $1500 to repair these nails.
Often they are too tightly attached to the roof, which can lead to propping up causing leaks to occur through the roof.
For a 1000 square foot roof, it will cost between $6000 and $12,300.
For a 2000 square foot roof, you’re looking at a low end of $13,000 and a high end of $21,000.
For a 3000 square foot roof, it will cost between $16, 000 and $27,000.
Other Roof Repair Issues
A chimney repair is likely to set you back between $750 and $1000. This is because the damaged chimney could be caused by structural damage on another part of the roof around it. This means additional repairs.
One example of this is the shingles around the chimney. These would need to be taken away and replaced with brand new shingles.
You can see whether a deal can be arranged with your contractor when it comes to this kind of repair. As it covers multiple areas, they might be happy to slightly reduce the cost that they would usually quote for a lone shingle replacement.
A skylight repair will normally feature some kind of leaking, caused by damage to the rubber gaskets and flashing used to secure it.
This might be a simple case of resealing the chalking with a solar sealant or a silicone sealant. If the damage is considerably worse – skylight flashing or damaged seals within the skylight itself – it could be that the whole skylight requires repair.
This might require totally new sealant and flashing. This might bump costs up to between $1000 to $3000. As is the case with considerable chimney damage, all the old shingles around the skylight will need to be taken away.
The area around the reflashed or resealed skylight will require replacement shingles. This might be a small portion of the roof, but it may require a larger space to be re-shingled. If this is the case, the cost will go up.
If you have more than one skylight to fix, the cost will of course go up in this case too.
It’s also worth noting that if a skylight is easier to get to, a contractor will likely reduce the quote of the job.
An entire replacement roof for a garage will come in at about $1500.
If a simpler repair is required, this will again be based on the materials needed. Base these quotes on the above list of materials, but be prepared for your garage roof repair to come in at a slightly lesser sum.
Keeping guttering well maintained is important. But sometimes they’ll need repairing, not just cleaning.
Patching a hole in guttering will cost around $2 to $4. This is the cost of roofing cement and a patch.
