Look out for these common residential roofing issues

As a homeowner, you need to inspect your roof frequently. By being proactive, you can save yourself time and money down the line. Look out for these common issues:

Roof leaks
Leaks usually occur along your vents or chimney. The seals in these areas can come loose over time. Leaks can also occur when your flashing becomes dislodged or when shingles are ripped away due to weather. When roof leaks are ignored, they can cause significant water damage inside and outside your home. If you find a leak, your roofing contractor from Dennis General Contractor will repair your roof quickly and correctly.

Wind damage
Did you know that wind is one of the leading causes of residential roofing damage? High winds cause your shingles to slide or bend. In some cases, storms can blow the shingles completely off your roof. This allows water to enter your home. During a severe storm, you can end up with both wind damage and water damage. If you find shingles in your yard or suspect you have roof damage, turn to Dennis General Contractor right away.

Hail damage
Your roof is designed to stand up to extreme weather. However, there's a limit to how much it can take. Hail can weaken or break your shingles, compromising the integrity of your roof. This can also lead to leaks. Dennis General Contractor offers complete roofing services, including hail damage repair. You can count on us for a complete post-storm inspection, as well as reliable repairs.

Blistered roof
If your roof is impacted by hail or subjected to high heat, your shingles can blister. Poorly designed or manufactured shingles can also blister, often for no reason. When you notice blistering, it's important to contact your roofing contractor right away. Our crew will come out as soon as possible and examine your roof. We'll either replace your entire roof or make the necessary repairs. Your insurance company may cover the replacement. Our friendly staff can help you file your claim.

Discontinued shingles
What happens when the shingles your roof is made of have been discontinued? The crew at Dennis General Contractor will work hard to find the best possible match from our selection of vendors. If there isn't a good match, your insurance company might pay for a total roof replacement. Reach out to our team for help with our claim.
