How to repair shed roof felt
When you leave damaged or weathered roof felt open to the elements, your shed soon deteriorates, allowing water and damp to damage your valuable building, tools and equipment.
But patching or replacing a felt shed roof is easy when you know how. Check out our free guide and video tutorial for the low down on patching a damaged felt roof.
- Remove finials and fascia boards
- Untack existing damaged felt
- Measure the roof and cut new felt to size
- Tack down new felt
- Re-affix fascia boards and finials
- Check regularly
- Tape measure
- Utility knife
1 - Remove finials and fascia boards
These should be easy to remove - they’ll either be screwed or nailed on. If they’re nailed, then gently prise them away from the shed. Keep them safe; you’ll want them later. If they've rotted, measure up and replace with timber from the local builders' merchant.
2 - Untack and remove existing damaged felt
You should be able to prise the tacks off with a flat-headed screwdriver. Take care not to damage felt that’s still intact underneath- otherwise you’ll find yourself with a longer job on your hands! Dispose of the old felt responsibly - it's best to take it straight to the local tip.
3 - Measure the roof and cut new felt to size
Measure the length of the shed roof, and make sure when you cut the felt that you allow for a two inch overlap on all sides. Offer it up to the roof to make sure you’ve cut to the right size.
4 - Tack down new felt
Tack down the edge of the new felt at six inch intervals. Remember to smooth it out before you tack to prevent wrinkles.
5 - Re-affix the fascia boards and finials
Screw the fascia boards and finials back into their original positions, and the job’s nearly finished! If you're using new timber to replace rotten fascias or finials, remember to treat it with wood preservative to prolong its life.
Trim off any felt that’s hanging below the fascia boards to keep things looking neat.
6 - Check regularly
