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:
Budgeting is important when tackling a project as big as replacing your roof. Below, we outline the average price range for replacing a roof on a 1,500 square foot home in Londonderry. We also outline price differences between common roof materials.
Installing a new roof is a big home improvement project that can cost an amount in the tens of thousands range when all is said and done. It's essential to research and find a top quality and trusted local roofing contractor for the job. Here are some key considerations when choosing a roofing contractor.
While the average homeowner may not spend a lot of time thinking about their roof, a roof plays an important role in keeping a home safe and secure. Keep alert for these signs that your roof might need professional attention.
Your roof's age and material are both important. The most common residential roofing material is asphalt shingles, which normally last about 20 to 25 years before needing to be replaced. Schedule an inspection if your roof is reaching this age to determine if it needs to be replaced.
Leaks are a common sign of roof issues. Water leaking through deteriorating shingles often leads to water stains on ceilings, walls, and insulation, or in your attic. Don't dismiss even small leaks, as they can still lead to mold and other damage.
If you can see your 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 are missing granules. Storms can cause exterior damage over time. To keep your roof in good condition, replace any shingles that are no longer attached or have gaping holes.
Roof flashing protects vents, chimneys, valleys, and other areas that pass through the roof. If the metal flashing is damaged, coming loose, or deteriorated, it can leak. Have any issues with roof flashing fixed right away.
A structural problem can lead to roof sagging or uneven slopes. If you notice signs of the roof sagging, get a roofing company to inspect it. An improperly supported roof deck will continue to deteriorate over time.
The best type of roofing material for your home in Londonderry will depend on factors such as your budget and how frequently you're willing to do maintenance.
Metal costs more but lasts longer, 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.
New Hampshire is one of the few states that does not require contractors to be licensed at the state level. You can check with your municipal government to see if there are any local requirements.
There is one exception: contractors who work with asbestos are required to be licensed by the New Hampshire Department of Environmental Services.
Roof cleaning costs about $499 in Londonderry. The total cost will depend on the square footage of your roof, how many levels it has, its material, and how thorough the cleaning will need to be.
Your roof absolutely impacts the energy efficiency of your home. For example, in the winter a good roof allows you to spend less energy heating your home. Certain 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 might be easier to get some costs covered if the damage is due to a covered weather event such as a severe storm. You should talk to your home insurance company to learn whether either of these situations apply to you.
A professional will either pressure wash or "soft wash" your roof, depending on the roofing material and how much cleaning is needed. Power washing is not recommended for certain roof types, such as asphalt shingles. To soft wash your roof, your contractor might use tools such as brooms and brushes, and chemicals such as detergent and bleach.
