Roof Replacements: Frequently Asked Questions

Should I get a shingle layover?

A roof layover, or shingling on top of your existing roof, is not the best option in general. It shortens the life of the new roof and it limits the warranty on the shingles given by the manufacturer, CertainTeed. When you put shingles on top of the older shingles, any hidden roof rot will remain hidden. It will not be fixed like it would be when the whole roof is replaced. Two layers of roof can cause problems with ventilation. Because of these issues, many roofing manufacturers cannot warranty their shingle material on layovers as long as they would on a tear-off.

Do I have storm damage / should I submit this to insurance? 

Ultimately your insurance company decides if you have storm damage but it’s always a good idea to have a local roofing contractor come take a look before you call your insurance. Some roof repairs will be less than or close to your deductible and will not be worth filing a claim with your insurance.

What’s the difference between the Landmark and Landmark Pro Shingle? 

There are two big differences between these shingles lines. The first is the Landmark has a 10 year warranty against algae and the Landmark Pro has a 15 year warranty against algae. If you have mature trees around your home; it might be a good idea to select the Landmark Pro as your shingle for your roof replacement. The second difference is physical weight. Landmark Pro is a slightly heavier shingle than the Landmark.

Are my shingles 50 year shingles?

All shingles are now labeled as limited lifetime shingles as opposed to 20 year, 30 year, or 50 year shingles. Most asphalt shingle roofs will last between 20 to 25 years.

Why are you switching my box vents to ridge vent? 

Box vents are being replaced with ridge vent because ridge vent gives a more effective ventilation for the overall roof. The ridge vent gives a cleaner look for the overall appearance of the roof.

Is ridge vent included in my roof estimate?

Yes – almost every roof replacement estimate Carlson Exteriors provides will include ridge vent. Take a look at your roof estimate and if it states “shingle over ridge vent” that means ridge vent. If your home does not have enough ridge line, box vents will be used and will be listed on your estimate.

Will you put starter in the rakes and eaves? 

Carlson Exteriors puts starter in the rakes and eaves of all roof replacements per shingle manufacturer requirements.

Why are you using synthetic felt instead of real felt? 

Synthetic felt is stronger and more durable than 15 lb or 30 lb asphalt saturated felt. It doesn’t tear as easily and will withstand all elements better if it’s exposed.

What if I have bad sheeting? 

If you have buckled or rotted sheeting, it will need replaced during the roof replacement. It’s impossible to tell the exact amount of wood that will need to be replaced until the shingles have been removed.

How far up do you install ice and water barrier? 

Per city code, ice and water barrier is required to be applied two feet inside living space. If you have larger overhangs, you will have more ice and water than if you have standard over hangs.

Do you offer financing plans or payment plans? 

Carlson Exteriors does not offer financing or payment plans. It is best to call your bank and talk loan options with them.

Are light color roofs better for heating and cooling?
