Hampton Roads Heat Wave: How 100° Days Affect Your Roof, Siding, and Home Exterior
What homeowners in Norfolk, Hampton, and Virginia Beach should watch for during this week's extreme heat
Virginia is facing a heat dome this week, with temperatures forecast to reach as high as 104 degrees across the region. While most of us are focused on staying cool indoors, extreme heat like this puts real stress on the outside of your home — and it's worth knowing what to watch for.
1. Roof Expansion and Shingle Stress
Asphalt shingles can soften and expand in extreme heat, then contract again once temperatures drop at night. This repeated cycle, especially during a multi-day heat wave, can accelerate cracking and granule loss over time — particularly on older roofs already showing wear.
2. Attic Temperatures and Ventilation
A poorly ventilated attic can reach well over 150 degrees during a heat dome like this one. That heat doesn't just raise your cooling bills — it can warp roof decking and shorten the life of your shingles from underneath. If your attic feels unusually hot or your energy bills have spiked, it may be worth having your attic ventilation checked.
3. Siding Warping
Vinyl siding in particular can warp or buckle in extreme, sustained heat, especially on walls that get direct afternoon sun. Look for any new rippling or gaps along your siding panels this week.
4. Deck and Fence Wood Stress
Wood decking and fencing can dry out and crack faster during heat waves, especially if they haven't been sealed recently. This is a good time to check for splitting boards or loose fasteners before the wood weakens further.
5. AC Condensation and Exterior Drainage
Your air conditioning unit will be working overtime this week — make sure the condensate line is draining properly and isn't pooling water near your foundation, which can contribute to moisture problems in extreme heat-humidity cycles.
What to Do Now
Most of these issues are minor if caught early, but sustained extreme heat has a way of turning small wear into bigger repairs by the time cooler weather rolls around. If you're noticing any of the signs above, or just want a professional set of eyes on your roof, siding, or attic ventilation before the next heat wave hits, Pratte Construction offers free inspections for homeowners across Norfolk, Virginia Beach, Hampton, and the surrounding areas.
