Today's Homeowner looks at dozens of datapoints on roofers to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Cost planning is important when tackling a project as big as roof replacement. Below, we provide the average price range for replacing a roof on a 1,500 square foot home in Portland. We also outline price differences between common roof materials.
Installing a new roof is a major home renovation that might cost tens of thousands of dollars when finished. It's essential to research in depth to find the best credentialed and most respected roofing company for the job. Here are some important considerations when choosing a roofer.
Though most homeowners don't think about their roof every day, it plays a vital protective role for your home. Remain alert for these common signs that your roof may need inspection and repairs from a professional roofer.
The age and material of your roof are important. Asphalt shingles, the most common roofing material for homes, typically last about 20–25 years. If your roof is approaching or past this lifespan, have it inspected to see if it needs to be replaced.
One of the most obvious signs of a roof issue is leaking. Stains on ceilings, walls, and insulation — or in your attic — usually indicate that water is seeping through worn or damaged shingles. Don't ignore small leaks, because even these can lead to mold growth and roof deterioration.
If you can see the roof deck boards underneath your shingles, it means those shingles are severely curling or losing their seal and need replacement. Shingles should lie flat to keep water from getting into your home.
Examine your shingles closely from a safe ladder or while on the ground. Look for shingles that have cracked or no longer have their protective granule layer. Storms can cause exterior damage over time. To keep your roof in good condition, replace any shingles that have become detached or are openly gaping.
Roof flashing creates a barrier against the elements around valleys, chimneys, vents, and other areas that penetrate the roof. If this metal flashing is cracked, peeling away from the surface, or otherwise deteriorated, it can allow leaks. Problems with roof flashing should be addressed promptly.
If you notice your roofline showing signs of sagging or unevenness, it could be a sign of a problem with the structure that requires professional inspection. A sagging roof deck will worsen over time if not properly supported or replaced.
The best type of roofing material for your home in Portland will depend on factors such as your budget and how often you're willing to do maintenance.
Metal is more expensive but is more durable, while asphalt will be cheaper up front but won't last as long. Wood roofs have better insulation than many other materials, which can be very beneficial in the winter.
In Maine, roofing contractors do not require any state licensure unless they work with asbestos (which requires specific licensure from the Department of Environmental Protection). However, the state requires "a written contract with a specific provision that prohibits payment up front of more than one third of the contract price" for any construction or home improvement projects worth over $3,000.
You can expect to pay about $453 for roof cleaning in Portland. Things like how many stories your house has, the extent of the issue, the size of your roof, and the material of your roof will all influence the total cost.
Your roof absolutely impacts how energy-efficient your home is. For example, in the winter a good roof allows you to spend less energy heating your home. Some roofing materials, like metal, provide better insulation than other types.
Your home insurance may cover some roof replacement costs if you use one of your insurance company's preferred contractors (if it has any). It may be easier to get replacement or repair costs covered if the damage is due to a covered weather event like an ice storm. You should reach out to your home insurance company to find out if either of these situations apply to you.
After your roof installation, check the roof's appearance. If it looks uneven or not uniform, this is a sign that the roof was not installed well. Also, make sure the flashing wasn't reused. Flashing is important to prevent leaks and water damage to your home. Finally, you'll want to check that your contractor placed an underlayment between the shingles and sheathing of your house. This helps prevent leaks and extends the life of your roof.
