How your roof affects your energy bills

As summer rolls into Nottingham, we often welcome the sunny skies and longer days. But while we’re enjoying the sunshine, your roof might be quietly taking a hit. At JTB Roofers Nottingham, we know that heat and prolonged sun exposure can cause unexpected issues for your roofing system – even in the UK, where scorching summers may not be the norm, but warmer weather is becoming more frequent. Whether you're a homeowner in Mapperley or a business owner in the Lace Market, here are some key hot weather roof maintenance tips to help protect your property during those warmer spells. 1. Inspect for Sun Damage Hot weather can cause roofing materials to expand, warp, or crack – particularly older felt, slate, or concrete tiles. Nottingham roofs, especially those exposed to prolonged direct sunlight on south-facing slopes, are at greater risk. Tip: Check for signs of fading, curling edges, or brittle materials. If you’re unsure what to look for, book a quick inspection with our team. 2. Clear Out Gutters and Downpipes It might not rain much during a hot spell, but when it does, sudden summer showers can cause problems if your gutters are clogged with debris. Blocked drainage can lead to water pooling on flat roofs or overflowing onto walls. Tip: Clear out gutters and check that water is flowing freely. If you have a commercial building in Nottingham city centre, routine gutter maintenance is even more crucial. 3. Check for Loose or Damaged Tiles The combination of heat and thermal movement can loosen tiles or cause existing cracks to worsen. This leaves your roof vulnerable to further damage – particularly when cooler weather returns and causes materials to contract. Tip: Keep an eye out for visibly misaligned tiles or granules collecting in your gutters (a sign of tile erosion). 4. Flat Roofs Need Extra Attention Nottingham’s flat-roofed homes and businesses – common in extensions and commercial buildings – are particularly prone to UV damage. Sun exposure can cause felt or membrane roofing to blister, bubble, or become brittle. Tip: Have your flat roof checked every summer. Preventative maintenance is far cheaper than a full replacement. 5. Ventilation Is Vital High attic or loft temperatures can lead to moisture build-up, mould, or even premature deterioration of roofing materials. Proper ventilation allows hot air to escape and helps keep your roof structure in better condition. Tip: If your loft feels like a sauna during warm days, give us a call. We can assess whether your current ventilation is up to the job. 6. Schedule a Professional Roof Health Check Even if everything looks fine from the ground, there could be underlying issues that only a trained roofer would spot. At JTB Roofers Nottingham, we offer free roof health checks during the summer months to give you peace of mind. Why Trust JTB Roofers Nottingham?
