Solar Shingle Installation
Many customers are familiar with the solar panels that have been on the market since 1956. While these panels are effective at gathering solar energy and have become more cost-effective over time, they’re bulky and some homeowners dislike the aesthetics of the tiles.
Solar shingles have emerged on the market as an alternative to solar panels. Compared to solar panels, solar shingles are lightweight and as easy to install as traditional shingles. Solar shingles look like ordinary asphalt shingles and provide the same kind of durability and protection—while also generating power for your home
At A1 Roofing, our team of professional roofing contractors can help you identify whether solar shingles are the right fit for your property, home ownership goals, and budget.

Warning Signs That You Need a New Roof
No one wants to deal with a surprise roof replacement, and there are important warning signs to look out for so you can take a proactive approach to maintain the condition of your roof. Here are five key warning signs that your roof may need maintenance or replacement.
1. Missing, cracked, or damaged shingles
Shingles serve a critical role in your roofing system. If you notice shingles are missing, cracked, or damaged, you should reach out to a roofing professional about a roof replacement.
The most frequent types of shingle damage are:
- Cracked, damaged, or curled shingles
- Missing or loose shingles
- Shingle damage or discoloration around vents, chimneys, or skylights
- Missing granules on shingles
While some shingle damage can be seen from the ground, you should also check your gutters. If you have shingle debris in your gutters, it may be a sign that your shingles are starting to fall apart.
2. Leaks
One of the most common reasons for replacing a roof is leaks. A leaky roof causes problems for the interior of your home, and it’s also a sign that the exterior of your house needs to be serviced.
Roofs may leak for a variety of reasons:
- Worn out shingles
- Storm damage
- Delaminating seams on your roof
- Wear from heavy equipment on roof
- Roof neglect
- Wear and tear from foot traffic
- Existing roof is reaching its lifetime value
While small leaks may be patchable, they often go unnoticed until the damage is significant enough to require a roof replacement
3. Interior water damage
If you’re noticing interior water damage, the culprit may be your roof. While a leak from a roof might look like a noticeable drip, water damage can also show up as water spots, stains, or discolorations in your attic, ceilings, or walls. Make sure to hire a professional to investigate all possible sources for the leak—but take note! When water damage shows up in your attic, ceilings, or walls, it very well may be a leaky roof.
4. Sagging roofline
What does your roofline look like? You should see straight, strong lines—no dipping or visible sagging. If your roofline sags, the culprit may be a framing issue. A water-saturated roof may also be the source of the problem.
5. Storm damage
Storms can significantly damage the integrity of your roof, even if they’re in perfect condition. Weather damage is especially common in regions that experience high winds or hurricanes, which can tear shingles from roofs or raise them up and cause them to crack. When this happens, your roof may leak or experience UV damage, especially if high winds are followed by rain, snow, or hail.
At A1 Roofing, our team of professional roofing contractors can help you uncover the source of your roof damage help to determine if a new roof is necessary to protect your home’s value.
